Description

The speed of temperature-sensitive part for the melt blended batch of thermokinetics change it is direct into Sample probes sense temperature methods
Technical field
The disclosure relates generally to drug manufacturing fields, and relate more specifically to active pharmaceutical ingredient (active Pharmaceutical ingredient, API) thermokinetics mixing (thermokinetic mixing) to produce new agent Type.
Background technique
The molecule that the high-throughput molecule screening technique that current pharmaceuticals industry uses already leads to newfound poorly water-soluble is real Body ratio is substantially improved.Since the pharmacokinetic profile of difference is abandoned molecule in the process of development, or due to non- Optimal properties of product, many treatment potentialities usually cannot be realized sufficiently in these molecules.In addition, in recent years, due to salt Form and neutral or the chemical modification of faintly acid/alkalinity drug practical limitation, pharmaceuticals industry, which has begun, to be increasingly dependent on Preparation method improves drug solubility.Accordingly, it is intended to enhance the advanced preparation technique of the dissolution characteristics of the drug of poorly water-soluble Current Good conveying is become more and more important.
The U.S. Patent application No.8,486 submitted by inventor same as the present application and other co-inventor, 423 are related to (thermokinetic compounding) compound in drug manufacturing field application thermokinetics.Thermokinetics is compound Or " TKC " is thermokinetics mixing up to melt blended method.By the pharmaceutical composition of the compound preparation of thermokinetics or multiple Condensation material can be according to well known to a person skilled in the art methods to be further processed, these processing include but is not limited to that hot melt squeezes (hot melt extrusion), melt are granulated (melt granulation), compression molding (compression out Molding), tablet press (tablet compression), capsule filling (capsule filling), film coat (film- Coating) or injection moulding (injection molding) is final products.
Although being mentioned using thermokinetics is compound compared to other methods known in pharmaceutical field in drug manufacturing field Significant advantage has been supplied, but can improve mix certain temperature-sensitives using thermokinetics mixer continuous fusion in some cases Or the processing of thermo-labile component.This group of subassembly, which is blended, may require that using the axle speed or reduced axle speed of raising to extend The time is handled, to be enough to assign the complete amorphism of batch (amorphosity) sufficiently handled.It has been found that in certain situations Under, such processing may cause overstep the extreme limit temperature or heat input, and heat input may cause the degradation of thermo-labile component.It has seen Carrying out the big calorimetric that entire batch absorbs may cause thermo-labile component thermal degradation, rather than improve whole batch temperature.Substantially Complete amorphism is well known measurement in medicine preparation and process field, in the composition for lacking substantially completely amorphism In, bioavilability may be damaged.
Summary of the invention
The disclosure keep punching research and develop in relation to by thermokinetics Application of composite in drug composite and composition The application of production.It is introduced at the basic physics of the drug component in the thermokinetics mixing chamber of thermokinetics mixer as batch The Short Description of reason will be helpful to understand this processing.
Thermokinetics mixer is completely unique in processing equipment field.Heating during mixed process is by processing material Not (not the needing chemical reaction itself, but the structure of crystalline drug can change) that material itself generates, such as without external heat exchange By the indirect heat transfer of radiation or convection current, or even do not directly heat such as through direct flame contact yet.Thermokinetics is mixed Clutch has the proprietary extension extended from drive shaft, and wherein drive shaft extends through the axis of tubular mixing chamber.These are proprietary Extension be formed as providing the angled contact surface along the direction of angle driving direction orientation, wherein angled contact Surface is suitable for reducing or eliminating pressure break, tearing or the fracture of processing component molecular.It is sent out in thermokinetics mixer during processing Raw processing step is usual are as follows:
1. controlled sliding occurs between processing component particles and extension contact surface, frictionally heats and contacts, thus High transient temperature is generated (since particle can roll and can slide over contact table in the contacting side of processing component particles Face, therefore and cause to be heated side);
2. in part high transient temperature can negatively affect the processing component particles of extended portion's heating chemical component it Before, these processing component particles are angularly sprayed the contact surface from extension, thus (due to mixing indoor extremely turbulent flow Condition) cause with mixing room air and other processing component particles it is instant cool down contact so that by by previous cunning Heat that is dynamic and frictionally heating contact generation is immediately assigned to the processing component particles of substantially entire batch;
3. the particle of angled deflection rubs each other, to generate the heating instantaneously spread, and reached in fusible particle In the case where melting temperature, melt granules are engaged and are opened with the non-melt particle of capture so that very crush or The non-melt particle of molecule dispersion is evenly distributed in melt granules;
4. the particle of angled deflection also from drive shaft axially and angularly outwardly, to cause sliding, friction It heats and is tangentially contacted with some of the inner surface of tubular mixing chamber, thus generated in the contacting side of processing component particles high Transient temperature so that particle due to it contacts with extension (direct or indirect) and when losing kinetic energy, particle quickly leaves The inner surface of mixing chamber and/or more there are the processing component particles of energy to push away or deviate the inner surface by other;
5. the instant cooling contact and mixing of above step 2 are repeated, with the particle for making to slide and frictionally heated It is disengaged with the contact of mixing chamber surface;And
6. since thermokinetics mixer connect at the end of thermokinetics mixing step thermokinetics mixer quilt Until closing, handle component particles violent and extreme turbulent flow be substantially it is instantaneous and substantially it is continuous (still It is not constant in the case where motor drive shaft velocity variations) so that the temperature of entire batch is substantially in entire mixing chamber Even, wherein temperature is surveyed at 1 centimetre to 2 centimetres of inner surface of the distance for frictionally heating surface and mixing chamber away from extension Amount.
It is heated to merge these processing component particles can one component particles will be handled using thermokinetics mixer Before the high temperature risen, thermokinetics mixer is mainly used for mixing, and fever is undesired side effect, thus by using mixing The coolant jacket of outdoor generates heat to reduce.The present inventor has been that the purposes that discovery thermokinetics is compound in pharmacy processing is made A part of isolated effort, wherein the disclosure is directed not only to chemical component-reservation mixing (chemical composition- Sparing field), and further relate to the structure change for causing thermally labile drug component.
This disclosure relates to be combined at least one excipient, polymer support or similar less activity or non-active ingredient At least one active pharmaceutical ingredient " API ", preferably at least part in crystal form active pharmaceutical ingredient (below In be known as components composition).Present disclose provides a kind of using following improved devices and/or method to the component in single batch The method that composition only mixes several seconds: when should terminate and incite somebody to action with determining that thermokinetics is mixed using only batch temperature measurement The thermokinetics mixed phase ratio that batch is removed from mixing chamber, the improved device and/or method shorten the batch processed time.
In the first embodiment of the disclosure, components composition mixing is carried out with lower first axle speed, wherein leading to Excess temperature rate increases the monitoring to batch for determining to carry out and realizes to the mixing of a large portion desired thermokinetics The judgement of generation completes the desired thermokinetics mixing of components composition using higher second axle speed later.
In second embodiment of the present invention, components composition mixing is carried out with lower first axle speed, wherein leading to The absolute value for crossing batch crystallinity determines or the reduction rate determination of batch crystallinity is monitored batch.In crystallinity or knot Brilliant degree reduces at the predetermined value of rate, and thermokinetics mixing is terminated, or using higher second axle speed in crystallinity or Crystallinity reduces the required thermokinetics mixing that components composition is completed at the second predetermined value of rate.
Inherence in the two embodiments is the discovery that, is widely tried in the thermokinetics mixing to components composition Test and mistake after, extend be exposed to realize needed for raised temperature needed for mixing time will lead to it is expensive and heat labile The degradation of drug molecule.The method that incorporation time needed for shortening must be found.The two embodiments meet these requirements.
The discovery result of first embodiment are as follows: lower first axle speed of components composition is blended in the processing and starts Only several seconds in provide a large portion components composition needed for mixing, but will lead to the extended of drug degradation Incorporation time is obviously needed, and has then used higher second axle speed later in this process.First embodiment packet Include such discovery: lower first axle velocity step only needs relatively short, and it terminates (and higher second axle speed The beginning of degree) it is triggered by sizable decline of the temperature increase rate of batch.When temperature increase rate in several seconds than initially counting The raised maximum temperature rate of the batch temperature of calculation it is small about 10% to 100% when, or when temperature increase rate have 1.5 degree/ Second to 0 degrees second increase rate (temperature (°F or DEG C)/time (second)) when, higher second axle speed will be started.Make us frightened It is odd, with the first reality all measured using individual temperature using individual axis velocity or only batch during entire mixed processing The mode of applying is compared, and can be realized as required mixing water under lower final batch temperature in a relatively short period of time and usually Flat (being determined by test and mistake, i.e., test mixed component composition after blending).The shorter place of first embodiment Reason time and lower final temperature make drug substantially non-degradable, and may be almost the same with the value of final products, And substantially eliminate the initial crystallinity of drug or pharmaceutical ingredients.Now to reduction crystallinity and increase mixed component combination The reason of amorphism of object, is described.
Structure change needed for hybrid medicine component is commonly known as amorphism or amorphous state.It is well known that The complex process almost all that solid particulate medicament is produced before final mixing or processing causes crystalline compounds.These purifying It closes object to be preferably amorphous before mixing with other components, to generate final desired composite medicine.It is well known that (Hancock et al. is in Pharm Res.2000 with the prediction solubility dramatically increased compared with its crystalline phase for amorphous drug April in year;17 (4): 397-404 deliver " what the real solubility advantage of amorphous drug is? (What is the true Solubility advantage for amorphous pharmaceuticals ?) ";www.ncbi.nlm.nih.gov/ pubmed/10870982).The biology that increased solubility only makes medical compounds be converted into amorphous state before administration is sharp One of expenditure advantage --- " importance of amorphous drug solid be its relative to corresponding crystal useful quality, generally send out Raw and physical chemistry unstability." (Yu, L. are Adv Drug Deliv Rev.2001 May 16;48 (1): 27-42 hair Table " amorphous drug solid: prepare, characterize and stabilize (Amorphous pharmaceutical solids: preparation,characterization and stabilization)";www.ncbi.nlm.nih.gov/pubmed/ 11325475).Yu further illustrates by crystallization and heat labile medical compounds (such as protein and peptide) and reverts to effectively Amorphous state technology status --- melting quenching, cryospray be dry, grinding, wet granulation and solvated crystalline it is dry It is dry.These processing are time-consuming and labour-intensive, and must separately be completed with other components with final amorphous drug Solid mixing, and processed crystalline drug solid is made to be subjected to degrading and recrystallize.Need may be implemented single or multiple crystallizations The method for being blended to produce required final drug dose composition of medical solid, and at the same time realizing needed for medical solid The a part of desired amorphous state as required final drug dose composition.
Second embodiment includes a kind of completely new approach of thermokinetics mixing for monitoring components composition.The present inventor is It is found that the method that the crystallinity of the mixing batch in thermokinetics mixer can be measured.It is mixed in thermokinetics mixing periods Indoor environment is preferably dark and turbulent flow, and the duration no more than about 30 seconds.Although it is contemplated that can directly measure The crystallinity of batch is mixed, so that mixing can be terminated when crystallinity is sufficiently reduced or effectively eliminated, but can in the past It is unknown in the turbulent flow batch mixing field of dry particl in the method for realization.The present inventor's first discovery uses Raman spectrum Instrument come measure mixing static amount solid material crystallinity, therefore can be used Raman spectrometer measurement mixed component composition Crystallinity.When analyzing the static sample of unmixed and mixed components composition, the Raman spectrometer of business allows user All wavelength detected associated with the other components of components composition are filtered out, and allows user to detect and measures group The drug of subassembly object or the percent crvstallinity of drug.Inventors have discovered that a kind of Raman spectrum probe, the Raman Spectroscopic probe head includes relatively narrow pipe, which has the required lens oriented in inner axial tube, and the end of the pipe is unlimited, with It is suitable for the light wave of Raman spectrometer detection in reception and transmission.It is without being limited thereto, for the exemplary suitable of second embodiment Raman spectrometer can be Princeton instrument company, especially TriVista CRS (http: // Www.princetoninstruments.com/products/specsys/trivistacr s/), TriVista CRS's swashs Light and detection device have been suitable for this relatively narrow pipe, and (in the case where TriVista CRS, pipe is that the microscope of standard is saturating Mirror tube).Probe in second embodiment uses the lens extension of Raman spectrometer, so that the distal portion quilt of lens extension It is directed in mixing chamber, being preferably directed into so that popping one's head in can detecte the knot of the particle moved between rotation shaft extension Brilliant degree.The close end of Raman spectrum probe is connect with Raman spectrometer and device microprocessor, the equipment of the device microprocessor User interface allows to check that the crystallinity of Raman spectrometer determines data and/or the crystallinity of Raman spectrometer is determined number Microprocessor is controlled according to mixer is transmitted to.When Raman spectrometer has determined mixing batch crystallinity and is transmitted to the data mixed When clutch controls microprocessor, mixer control microprocessor can make the mixing of components composition batch terminate or make axle speed Degree improves and terminates mixing hereafter.In this second embodiment, when drug or drug change from crystallization amorphous form, from The Raman scattering of drug or drug crystal stops or cannot be detected, i.e., present energy is by different from drug or drug crystal Energy state absorbs.When Raman probe detection drug or drug crystal disappear substantially, so that not needing to components composition The processing control of thermokinetics mixing carries out temperature measurement.
It is of the invention in preceding general introduction
In contrast, the processing or thermo-labile drug component that thermo-labile drug component is mixed with other components are processed into itself The processing of powder type is all from being not intended to that thermo-labile drug component is made to reach its melting temperature.Instead, it is desirable to the result is that basic On be thoroughly mixed or powder type.It, will if amorphism substantially completely may be implemented in identical mixing step Avoid individual processing step.Inventors believe that since he is in terms of using thermokinetics mixer processing commercial polymer Many years of experience, thermokinetics mixer can be to avoid decomposition of the thermo-labile drug ingedient in required mixed processing.However, this It is also contemplated that even if heated very short time may also lead to the decomposition of component, these components usually require high-cost inventor Several preceding processing steps of special technology application.It is considered as desirable by the inventor to how further shorten mixing batch to exist The processing time in thermokinetics mixer, but still it is able to achieve the amorphism substantially completely of batch.
Additional general introduction to first embodiment and second embodiment of the invention
The present inventor observes when testing in thermokinetics mixer to the thermo-labile drug component of test batch The phenomenon that he is occurred when using thermokinetics mixer.After the initial mixing phase carried out with lower axle rotary speed, batch Secondary temperature will increase and stablize (plateau).It will be unable to produce in processing batch to be further processed compared with low velocity Raw amorphism substantially completely.The inventors discovered that axle rotary speed is increased to higher level and is continued extremely short Period can generate amorphism substantially completely in gained batch, and component is hardly processed heat and divides Solution.
However, it has been found by the present inventors that the above method of result needed for obtaining extends the processing time in which may not be necessary. In the present invention, with etc. temperature under lower axle rotary speed to be seen it is stable and then axle rotary speed is increased to it is higher Axle rotary speed compare, handle batch processing the time and by high temperature time shorten.In the present invention, high-speed temperature passes Sensor accurately and substantially immediately measures average batch temperature, which is stored in mixer or batch In microprocessor (including CPU, memory, clock and I/O unit), which controls under program in batch Operation.It calculates the temperature sensed and one or more previously stored temperature and its compared with the record time temperature and becomes Change rate.When detecting that rate temperature change is decreased or increases to required temperature raising triggering rate, axis rotation speed Degree is increased to higher axle rotary speed from lower axle rotary speed.
It is smaller near the distal portion of probe irradiated by laser beam that Raman spectrum probe is preferably positioned to detection The crystallinity of particle in the movement of sample space.The list that light from irradiation area is collected by lens and passes through Raman spectrometer Color instrument is sent.It is filtered close to the wavelength of laser and drug or drug due to elastic Rayleigh scattering, and the light that remaining is collected It is dispersed on detector.Lead to laser photon with molecular vibration, phonon or the laser of other excitation interactions in system Energy deviate upward or downward.The transfer of energy gives the information of vibration mode in system.In the feelings of second embodiment Under condition, these vibration modes are carried out to handle the average crystallite for determining mixing batch by the algorithm of temperature sensor manufacturer Degree.Since the detection time of mixing batch crystallinity can extend to about 3 seconds, device microprocessor or mixer control are micro- Processor selectively runs crystallinity set point program, which determines the fall off rate of batch crystallinity And it is stored for prediction and uses.Since over-mixed 3 seconds or more (the batch crystallinity detection carried out by Raman probe) can Can lead to drug or drug degradation, it is therefore preferred to the required components composition of testing experiment batch, with obtain terminate mixing or Speed improves triggering set point.These triggering set points are together with the crystallinity absolute value or crystallinity fall off rate that currently measure It uses, so that it is required to obtain to stop mixing (or axle speed raising) before currently detected required crystallinity level Thermokinetics mixing.
Referring now to first embodiment, the present inventors have additionally discovered that the rate temperature change at point on the first temperature platform The viscosity variation of the Best Times of axle rotary speed is improved corresponding to instruction.The present invention measures the temperature change speed of mixing batch Rate, and axle rotary speed is increased to higher level from reduced levels according to following processing methods: (1) change of average batch temperature Change rate to be calculated as having reached the triggering rate for the temperature change that instruction batch has been realized in required viscosity variation, In, required viscosity variation indicates that significantly improving for amorphism, or the rate of change of (2) average batch temperature have reached The expected triggering rate of temperature change, this shows after considering the processing speed of temperature detection and calculating, and batch will be realized Indicate the required viscosity variation that amorphism dramatically increases during short process phase.In the case where processing method (2), It is actually detected and calculate axle rotary speed is increased to higher level before desired rate temperature change, to avoid detecting And calculate the unnecessary incorporation time after desired rate temperature change.
In the present invention, obtained pharmaceutical composition due to substantially completely mixed and have amorphism and it is excellent Selection of land has increased bioavilability and stability.
It is blended and disperses to add certainly in the mixing chamber of super mixer as described above, a kind of thermokinetics mixer is provided The method of hot mixt, wherein First Speed is changed to the second speed in processes after reaching the first expectation processing parameter Degree.In another embodiment, second speed can be kept until reach final process parameter, axis rotation at that time be stopped and Melt blended batch is extracted out or is discharged from mixing chamber, with for further processing.It in another embodiment, can be Midrange speed change one or more times is made to axle rotary speed between two speed and stopping axis rotation.Determine that axle speed changes Processing parameter be scheduled, and can sense and show, calculate, speculating or otherwise true with reasonable certainty It is vertical, change so that making speed during single rotation continuous processing of the batch in the mixing chamber of super mixer.Another implementation Mode is the change of the shape, width and angle of the facial parts being projected into main process task volume using shaft extension or protruding portion Change to control and be transported to the rotary shaft energy of extension or protruding portion and be converted to and hit the part of extension or protruding portion Intragranular thermal energy.
Present inventors studied a variety of mixtures comprising thermo-labile component are melt blended in thermokinetics mixing chamber. Inventors have surprisingly discovered that using multistage speed in some lots of single rotation continuous operation containing thermo-labile component Degree is solved the problems, such as more than the limiting temperature of batch or excessive heat input.Inventor is also unexpectedly found that, changes axis and prolongs It extending portion or the shape of protruding portion, width and leaves the angle of axial plane of axis and provides the shearing that control is transported to particle Method, then provides the control to the axis energy for being converted to thermal energy, these thermal energy can be used in softening or melting heat power Learn the polymer moieties of particle in mixing chamber.

Fig. 5 shows method of disclosure and using certain potential between the thermokinetics mixed method of substantially single axle speed Difference.Fig. 5 shows batch sensing temperature, the axle rotary speed as unit of RPM and any moment in processing and is input to The figure of the ampere number of the directly proportional measurement of energy in batch.As a specific example, the following combination of thermokinetics processing Object is to form griseofulvin: the batch of PVP (1:2 ratio), and batch size is 60 grams.Griseofulvin represents thermo-labile API.PVP Represent excipient.A series of three tests show thermokinetics in Fig. 5 and similar with shown in Fig. 3 and Fig. 4 in structure Carried out in mixer, wherein forward face 21 is prominent on direction of rotation forward and transverse width is about 1.0 inches, and keep with The plane and height that about 30 degree of leading edges for exiting through forward face 21 are stretched out from the axis of axis 23 are about 2.5 inches.Batch in Fig. 5 Secondary to handle under the conditions of thermokinetics self-heating, which use substantially single axle speeds.Y-axis is suitable for temperature (value is multiplied by 10) With the axle speed as unit of RPM (value is multiplied by 30).Time in x-axis is with 0.1 second for increment.If the composition of the batch with Be significantly higher than rotation axle speed --- that is, 2500RPM or higher --- the thermokinetics mixing of speed shown in Fig. 5, then it is final to produce The inspection of product is shown to be unacceptable crystallization and insufficient amorphous.Should the result is that those skilled in the art beyond expection 's.The thermokinetics higher axle speed of mixing art teaches ensures preferably to mix, but it is in the higher of these materials There is no occur under axle speed.When in lower rotation axle speed as shown in Figure 5 as processing example batch composition when, The inspection of final products shows that it is that abundant unbodied and bioavilability is abundant.But have occurred thermo-labile API can not The thermal degradation of receiving, this causes batch unacceptable.
In Fig. 5, in the zero-time, ampere number is increased to 35 amperes (1050 in figure) immediately.The discharge of batch is About 17.6 seconds, or when RPM is significantly reduced.Rotation axle speed is set as 1800RPM, and reaches in about 2 seconds of beginning The speed.In about 7 seconds, batch temperature reaches 260 °F, the shearing transition temperature of excipient.Change temperature higher than the shearing The shearing resistance of degree, excipient significantly reduces, and by particle and melted material to protruding portion surface and mixing chamber internal surface Shock and be transported to the energy in batch be then significantly reduced (when batch temperature reach shearing transition temperature when, electric current peace Training number is reduced to about half).From about 7 seconds to about 16 second, the batch temperature of composition while batch constant absorption big energy Degree does not increase.This raised energy conversion of temperature that do not result in is at thermo-labile or heat sensitive components thermal degradations.The test one As property confirmed the significant quantity component once in the melt blended batch of thermokinetics --- i.e. be greater than 5 weight percent, 10 weight Percentage, 20 weight percent or 30 weight percent --- reach it and shears transition temperature or fusing point, what entire batch absorbed A large amount of thermal conductivities cause thermo-labile or heat sensitive components thermal degradations, rather than increase entire batch temperature.This obviously shows 7 in Fig. 5 To 16 seconds time ranges, batch temperature actually reduced and has lasting energy input into batch at this time.
Use batch identical with Fig. 5 and thermokinetics mixer in Fig. 6, but used in continuous rotation batch processed Two speed.In Fig. 6, the programmable logic controller (PLC) for being connected to infrared sensor and variable frequency drives is used for detection batch Batch temperature is compared by secondary temperature with predetermined set-points, and the rotation axle speed of thermokinetics mixer is changed automatically Become another speed, lasting processing is until discharge batch by opening bottom release door.First Speed is set as 1800RPM, second speed are set as 2600RPM.The predetermined set-points of batch temperature are selected as substantially below excipient shearing and turn Horizontal 200 °F of temperature.It in the preferred embodiment, can be in the advance for the shearing transition temperature for reaching substantive component Scanning frequency degree changes, and system needs the batch temperature sensed to be sent to programmable logic controller (PLC) and the practical change of axle speed Between response time.As shown in Figure 6, there is no that the energy for being input to batch is not used in makes whole batch temperature liter It is high.The batch of processing shows substantially completely amorphism, and can not detect in about 6.5 seconds entire processing time API thermal degradation.The processing time of the time and 17.6 seconds in Fig. 5 form sharp contrast.
Fig. 6 shows substantive component or a part of the axle rotary speed in thermokinetics batch of certain thermo-labile components It when reaching shearing transition temperature or fusing point or should significantly improve before, the processing time later should minimize.In certain embodiment party In formula, First Speed should improve about 100RPM, 200RPM, 300RPM, 400RPM, 500RPM, 600RPM, 700RPM, 800RPM, 900RPM, 1000RPM or more and become second speed.In other embodiments, after second speed starts to batch from Mixing chamber release the processing time should be batch First Speed handle total time about 5%, 10%, 15%, 20%, 25% or More.
Well known in the art, the shock of particle on the surface assigns particle energies.Thermokinetics self-heating mixer One feature is to provide the shock to the particle containing polymer, thus the energy of imparting is partially converted into thermal energy with soften and/ Or melt these polymer.But thermokinetics mixing field general guide those skilled in the art are hit with that cannot finely control The mode of thermal energy can be converted to by, which hitting, provides shock of the particle in thermokinetics mixer.The disclosure is provided and is described for this The method of the control of sample.Highly cross-linked polymer and heat-curable compounds is very difficult to soften and melt, also exactly because of the original Cause is preferred, that is, highly cross-linked polymer and heat-curable compounds is resistant to breakage.But some dynamic using heat In some combinations of the component of mechanics mixed processing, highly cross-linked polymer and heat-curable compounds show bid value.It is true On, due to the fusing and blending of resistance to any other modes, thermokinetics mixing substantially handles high cross-linked polymer and thermosetting The unique method of property material.Field is mixed in thermokinetics, will improve rotation axle speed and/or processing Understanding Time is that can use Enough Impact energies are converted to thermal energy to cause softening or molten state for further processing in induction refractory fluidized polymer Method.Present embodiment, which discloses, can effectively control the device and method that Impact energy is converted to thermal energy.
Two main impact surfaces --- forward face and top surface of axis --- are controlled in thermokinetics mixer and are hit It hits and is converted to thermal energy.The two surfaces are that (volume is hereinafter also referred to as the volume for protruding outward mixing chamber of shaft extension " main process task volume " comprising from the inside cylindrical wall of mixing chamber radially-inwardly about 1 inch of most of confined area) 30% Or the facial parts of the internal cylindrical surface of less facial parts and mixing chamber itself.Change mixing chamber internal cylindrical surface Be not practicability selection, be since the surface is fixed, and the surface must keep smooth and keep uniform cylindricality with It resists the accumulation of melted material and allows to contact with movement by the self-heating that sliding and slidingtype occur for the particle of mixer room.
The disclosure is transported to extension using the variable for the top surface of shaft extension being projected into main process task volume to control The rotary shaft energy in portion is converted to the intragranular thermal energy hit with the part.It has been found that changing the width of interarea portion part Spend and leave axis axial plane angle provide be transported to the part hit particle shearing controllable variations, after And the axis energy for being converted to thermal energy is controlled, these thermal energy can be used in softening or melting the poly- of the particle in thermokinetics mixing chamber Polymer portion.
Referring again to Fig. 3 and Fig. 4, as long as discovery particle is in mixing chamber, accumulating the shearing being subjected to will lead to heat power Learn mixed self-heating phenomenon, the shearing by the shape and size on the direction of rotation facial parts surface of the extension from axis with And mixing chamber internal surface determines.Substantially all particles during axis rotates in mixing chamber are all in 30% volume of outside of inner space In, i.e. the centrifugal force holding particle and melted material of extension rotation leave the central volume of mixing chamber.Therefore, it is necessary to design The thermokinetics mixing chamber of effect, so that the distal portions of shaft extension are formed as realizing direct high shear (extension end front On face), indirect high shear (mixing chamber internal surface on) and material centrifugation is maintained at three kinds of functions in mixing chamber external volume.Axis The top surface of extension 30a to 30c forms generally vertical rectangular portion, the plane angulation of the rectangular portion and the axis by axis 23 Degree setting.It has been found that changing the simple rectangular portion of axis or width, angle or the unexpected improvement of shape of bow-shaped leaves and controlling The accumulation shearing for making the particle being transported in the mixing chamber of thermokinetics mixer is then provided to temperature-sensitive in processing batch Or the control of the assigned thermal energy of thermo-labile component and desired heat input.
For these specific comparisons of the operation of the heat power mixer with several interarea portion part configurations, it is assumed that logical Energy input and the axle rotary speed for crossing axis are roughly the same, and the number of shaft extension and its in mixing chamber along shaft length Interval it is essentially identical.Therefore, compare the influence that display is changed to interarea portion partial shape.
In general, the length relative to interarea portion part, which reduces width, improves the axis energy for being converted to thermal energy, these heat The polymer moieties of particle in thermokinetics mixing chamber can be used to soften or melt.Width has to be larger than minimal-contact width So that particle is subjected to hitting along the sliding of width, particle is induced " to slide " or assign the CONTACT WITH FRICTION of energy, is hitting institute The period for stating part rolls and sliding.Only normal graze of the particle on surface impinges upon the heat assigned for softening or melting Relative nullity in dynamics self-heating energy.But in some cases, sometimes with interarea portion part handle be easy fusing and Thermo-labile or thermally sensitive polymeric provides only such graze and hits (glancing inpact) with to being applied to the component Heat provides more controls.It is consistent with this introduction, usually using the axial plane minimum angles with axis (for example, at least 10 degree or extremely Few 15 degree) the interarea portion part processing of the minimum widith (at least 0.25 inch) of alignment is difficult to or resisted through application heat and softened Or fusing polymer, the time of contact with essentially identical energy input is provided, so as to by these energy be distributed into sliding and Rotary motion improves the self-heating of particulate polymers content.
At present in DraiswerkeThe design of the shaft extension found in thermokinetics mixer has Fig. 8 Shown in cross section 50, cross section 50 has the totality substantially spiral that circular interarea portion part 51 and width are about 2 inches Shape shape.The design it is not significant to be directed toward the relative shear 52 shown in several short arrows of interarea portion part 51.Therefore, this Device melts the molten of substantially resistance to softening or fusing to generate the heating of enough thermokinetics improving processing time and shaft power It is relatively expensive in terms of body polymer blend.Therefore, have the thermo-labile or thermally sensitive polymeric of such resistance opposite for handling It is insufficient.Thermokinetics mixing field does not propose the width that the axial plane relative to axis changes interarea portion part or angle to poly- The thermokinetics processing for closing object has any influence.The disclosure discloses such some embodiments in Fig. 9 to 12.
Fig. 9 to Figure 12 respectively illustrates interarea portion partial cross sectional 53 to 56, cross section 53 to 56 have it is of same size and With its represented by extension axis axial plane at 15 degree, 30 degree, 45 degree and 60 degree angles interarea portion part 57 to 60.It is main Projection width of the facial parts 57 to 60 on axis axial plane indicated respectively with length 65 to 68 and with relative shear 61 to 64 is directly related, wherein improve interarea portion part in the case where same widths reduces relative to the angle of the axial plane of axis Projection width in plane and unexpectedly improve same axis power input, on rotation axle speed and axis between extension Away from the relative shear in the case where with arrangement.Utilize the disclosure, it now is possible to control and pass through in thermokinetics mixer extension Convey the self-heating of shearing.Interarea portion partial width is reduced while keeping the angle relative to the axial plane of axis to maintain Thermokinetics handles total heat input in batch, and improves any list along the projection length of the axial plane of axis by reducing The shearing of only particle.
Therefore, now by thermokinetics self-heating be mixed and blended processing polymer shear strength can with pass through The relative shear energy that shaft extension assigns in mixer matches.As very common, when the polymers compositions packet in batch When both polymer containing high shear and low sheraing polymer, needs further to design and refine.It provides and is suitable for high shear component The shearing that interarea portion part assigns can convey too many thermal energy to low sheraing component.In this case, low sheraing component is inclined to It is rolled in softening and along the width of interarea portion part, so that the heat of generation is further improved, and high shear component is tended to It is easier to leave the surface.Such case may tend to cause not exclusively to mix, wherein the fusing of high shear component it is insufficient or Low sheraing component overheat.Still also need to realize the master of the high and low shearing component conveying optimizing shear into thermokinetics batch Facial parts design.
It has been found that increasing interarea portion partial width realizes the optimization.It is being 15 degree to 80 degree with the axial plane of axis Under angle, the interarea portion part that width is at least 0.75 inch is the traveling of both high and low shear polymer solution components in batch Enough paths are provided, so that high shear component is kept with the sliding of sufficiently long interarea portion part and gliding contact to generate heat And heat is absorbed to soften, to be blended with low sheraing component from low sheraing component.

Figure 19 shows another important embodiment of the dynamics mixer of the disclosure, and wherein half 5 and 7 and door 6 exist Inside is respectively lined with internal liner 5a, 7a and 6a.Liner is suitable in the operation process of mixer and in half 5 and 7 and door 6 Surface is closely positioned adjacently, to provide any in the acceleration desired many groups of thermokinetics frictional contact surfaces of particle One kind, the expectation surface are selected from the material of any suitable of liner 5a, 7a and 6a or optimization.Figure 19 shows adjacent thereto The exploded view of (when installation) part separated liner 5a, 7a and 6a.Half 5 and 7 is bolted together so that liner 5a It is fixed to serve as a contrast the inner surface in these half 5 and half 7 with 7a.The hole of the end of liner 6a allows liner 6a to be bolted To door 6.In thermokinetics mixer well known by persons skilled in the art, the inner surface of mixing chamber, which is limited to have, to be surrounded and closes Those of enough mechanical and calorific intensitys needed for the thermokinetics operating of such mixing chamber steel alloy.It is thus known that heat it is dynamic The processing capacity of mechanics mixer is only limitted to not attach to excessively the slippery inner surface of the steel alloy of mixing chamber and at the same time beneficial Ground, which is hit, those of frictionally heats mixture on these surfaces to provide for the particle in mixture.In addition, thermokinetics is mixed Even if relatively small slight abrasion, which may also be significantly changed, on clutch mixing chamber internal surface generates thermokinetics to indoor particle The efficiency of heating, wherein the distance between shaft extension and the inner surface of mixing chamber are specifically designed as optimization by mixing chamber The thermokinetics of the interaction of the particle moved between inner surface and shaft extension heats.Therefore, such mild wear can Need replacing the group of entire relatively expensive half 5 and half 7 in such thermokinetics mixer.Embodiment of the present invention disappears In addition to such expensive cost.Liner 5a, 7a and 6a are much more relatively cheap than half 5 and 7 and door 6 on replacement cost.Liner Replacement it is very simple and quick.Preferred liner composition comprising stainless steel (alloy with the chromium greater than 12 weight percent) with And other such steel alloys, titanium alloy (such as peptide nitrogenize or nitrogenate) and wear-resistant and hot polymer (ratio Such as).Another embodiment of the disclosure provides the non-smooth inner surface of liner 5a, 7a and 6a, for example, formed about Liner 5a, 7a be parallel with the internal cylindrical surface of 6a or helicla flute, surface texturizing (texturing) and/or electropolishing.Lining The such material and texture of piece 5a, 7a and 6a are intended to be optimized or desired balance of properties, and the balance of properties will reduce Thermokinetics fusing the undesirable of particle sticks and/or promotes between shaft extension and the inner surface of liner 5a, 7a and 6a The thermokinetics CONTACT WITH FRICTION of the mixing chamber particle of operation.
Passing through the material for selecting liner 5a, 7a and 6a or texture to obtain the another of the disclosure of thermokinetics mixing purpose It, can be by changing similar material with the inner surface those disclosed for being just directed to liner 5a, 7a and 6a in one embodiment Composition and/or texture adjust the shaft extension of preceding striking face including shaft extension and top striking face.
Another feature of the disclosure is, the top surface of shaft extension, at least a small amount of height that extends back and prolong higher than axis The height of the forward face of extending portion hits face (face 22 of Fig. 3 and Fig. 4) those of on it to form ramp structure and indoor particle It is to mix the main positions worn in chamber internal surface.Design of the consequence of the discovery for shaft extension in thermokinetics mixer It is meaningful.It has been found that such top surface has the function far different with forward face.The forward face of shaft extension along Its width being rearwardly directed to pulls particle, causes substantially to drive particle along the axis direction of drive shaft.Such axis drives Then dynamic particle tends to encounter another forward face of the shaft extension of another line behind shaft extension.By axis rotation driving with The movement of the particle of face contact is far different at the top of shaft extension, compared with the forward face of shaft extension, in such movement Impart the bigger friction thermokinetics energy of particle.
Figure 20 shows side view (the axis side for the axis that shaft extension 30 is installed of the removable portion of shaft extension 30 To view), the figure shows forward faces 21 and top surface 22.Reference altitude 30b to 30d is measured from datum level 30a.Before Portion face 21 or top surface 22 are not shown in the plan view, but are shown with its projection in the axis side view of axis.Top Face 22 includes leading edge, which is increased to height 30b from height 30c, and is hereafter bent upwards backward higher to having The similar inclined back edge of height 30d.The only a part inner surface of half 7 is shown as separating with top surface 22, and part P1 is extremely P4 indicates to impinge upon on top surface 22 and then impinge upon the path of the particle of the inner surface of half 7 first.Have been found that mixing chamber Greatest wear region in any interior surface is along the leading edge indicated by the line from height 30c to 30b --- that is, particle Rum point at the P1 of part --- region backward.Most of kinetic energy is obviously converted to friction of the particle in the region and adds Heat, as the noticeable wear by the hardened surface proves.Compared with starting along proximal edge at height 30c, top surface 22 increase at it along the distal edge of height 30b to 30d rapider, cause along part P2 and from height 30d to half 7 The relatively long friction travelling route of the particle of inner surface inclined-plane transmitting.In part the inner surface friction of P3 and half 7, rotate and drag After dragging contact, the particle heated extensively is rebounded from the inner surface of half 7 to be contacted again the top surface of another shaft extension.Portion The length of P2 is divided substantially to control the friction required for the thermokinetics mixing and fusing of granules batch in disclosure mixing chamber Heating time.The disclosure includes selection shaft extension, and the extension provides in thermokinetics mixing for shock particle longer Or the top face contact path of short length and the deviation angle, so that the significant or most of indoor particle is frictionally heated contact control In desired batch temperature.
Figure 21 shows the perspective view of the particular implementation of the shaft extension of Figure 20,21 He of forward face with spill Top surface 22, the forward face 21 and top surface 22 of spill can generate the part for being respectively used to the variable-length of part P3 ' and P3 " P2 ' (longer) and P2 " (shorter).In some embodiments, top surface 22 includes prolonging from its leading edge to its edge after The convex that the radius stretched is about 4.5 inches.
