Description

FIELD OF TECHNOLOGY

The invention relates to the construction of a film reactor-extruder, designed to obtain a porous means directly at the place of its use, in non-factory conditions. In the claimed design, a porous agent is obtained and withdrawn from it in the form of a porous cured mass formed into a predetermined profile, which is finally re-foamed and / or cured at the application.

Porous means, the receipt of which is advisable to carry out in the inventive design of the film reactor, include small heat-cold-sound and damping profiles, which are used in industrial and domestic construction, as well as in the repair of building structures. This also includes porous medical devices - therapeutic, dressings, hemostatic and gypsum-like drugs. These include compact tourist watercraft and bedding, ambulances, erection and repair of small shelter structures, etc. Equipment film reactors of law enforcement, paramilitary, space units and emergency units is an actual application of the claimed invention.

BACKGROUND

Various constructions of film container containers are known, consisting of sealed film chambers connected through removable baffles in which reaction components are stored to form the target product by manual mixing, including a moving expandable mass, to obtain a porous shapeless from it outside the film reactor material or material formed by the configuration of the cavity being filled (see our patents of the Russian Federation No. 2245284, 2245285, 2276163, 2297376, decisions on the grant of patents on application m No. 2006100246 and 2006107426). The target product that can be produced according to these inventions, i.e. to be released from container reactors for foaming, curing and use, or to remain with the container reactor for later use with it, are either the final target products (blends, polymers, primers and putties, paints, packaging structures, sleeping accessories, etc. ), a monolithic or porous structure, or "raw" semi-finished products requiring outside the container reactor, in which such semi-finished products were obtained, curing or foaming and curing. In known designs of film containers, reactors, as a rule, use any one method of manual mixing of the starting components - the method of "crushing", or the method of "crushing", or the method of "shaking-shaking".

In U.S. Patent No. 4,929,449, which claims the design of a therapeutic film mixer container, the author recommends using all known manual mixing methods for mixing low-viscosity, easy-to-mix, soluble products, calling only the shaking method (widely used in medicine for rigid containers).

In all the constructions of film container reactors known to us, the target product is released from them or stored in them in the form of a shapeless reaction mass, which can then be molded into some means, for example, packaging, if the foam mass produced in the container has not yet completely solidified and is mobile .

Closest to the claimed design of the film reactor we described in RF patent No. 2297376 (application No. 2002125394). In accordance with this patent, a film reactor for producing a porous material at the place of use consists of basic sealed film chambers connected through a removable baffle and containing the starting components to obtain the target product by manually mixing them by the “crushing” method in a common chamber, which is formed by eliminating the specified partitions. The container also contains a free auxiliary chamber, the volume of which is established on the basis of the requirements of the “crush” mixing method. With all the perfection of this design, it does not allow the production of porous means of a given profile and with the technological characteristics required for use. A significant drawback of the known construction, as the practice of its application has shown, is also the inability to use the more intensive manual mixing method in film containers today - the method of shaking and shaking, is limited only by the crushing method.

The known reactor is limited to releasing a shapeless liquid mass from it, foaming already outside the container, i.e. The reactor acts here as a component mixing apparatus, but not as a reactor for establishing and implementing in it the required interaction of components of an adjustable degree of their conversion for subsequent organized extrusion of the formed foam mass through an exhaust device. The manufacture of a known reactor-mixer from a multilayer barrier film material (as well as placing it inside the outer package) does not allow for operational visual control of the technological process of obtaining the reaction foam. The identification of the indicated limitations of the known design and the need for porous means of different degree of readiness (survivability) and profile stimulated the authors to create the construction of a film container-reactor-extruder to obtain various porous means that can be removed from the reactor to the place of consumption with a given degree of porosity, curing and profile. In this regard, for the claimed design of the film reactor, which involves obtaining the target porous means inside the protective shell from the material of the reactor itself, in the prior art we reflect the popularity of the film package for the manufacture of foam cushions at the place of its application (US patent No. 5899325 and our patent of the Russian Federation No. 2245284). According to these inventions, the mixing of the starting components stored in the sealed main chambers of the film container is carried out in a common mixing chamber and then the reaction mixture in the form of a foaming mass is discharged into an external auxiliary bag, in which the main chambers themselves are located. In this outer bag, the expandable mass acquires its final cured form, which is dictated either by the shape of the outer bag used, or by the shape of the product into which the bag with the reaction mass expanding in it is placed, for example, into a container in which some fragile product is packed. The peculiarity of this design is that the outer film bag covers the main chambers of the container and, when the foam mass is released into the outer bag, it envelops the main chambers and does not allow the porous product to be completely freed from the outer shell when necessary under the conditions of use or according to economic requirements. For example, for medical purposes, if necessary, have a porous means of a given survivability and profile. It is therefore no coincidence that this design does not at all contain a device for discharging a porous mass from an outer packet. She does not pose such a task.

SUMMARY OF THE INVENTION

The objective of the invention is to create the design of a film reactor-extruder to obtain at the place of application of various chemical composition, porous structure and profile of porous means.

According to the invention, the film reactor-extruder consists of sealed film chambers connected through a removable baffle, which contain the starting components to obtain the target product (porous means) by their interaction in a common chamber, formed by removing this baffle and subsequent release of the moving porous mass from the common chamber . In order to be able to control the chemical composition, degree of cure, porous structure of the reaction mass and its mobility at the stage of interaction of the starting materials inside the reactor, as well as to form the profile of the porous mass discharged from the reactor and the produced porous product, the reactor contains a free auxiliary volume, which is connected to shared camera. In some cases (with low porosity of the produced product), the auxiliary volume is formed in the very common chamber. In this case, the total volume of the reactor, which is formed when all its partitions are removed and which it is able to accommodate, is at least equal to the volume of foam mass formed in the reactor:

Vo≥K (Vk)

where: Vo is the total volume of the reactor;

K = UK / Pack

K is the coefficient of pore formation;

Vк - the sum of the volumes occupied by the initial components;

UK - the average specific gravity of the starting components;

Yn is the apparent density of the mobile foam formed in the container.

The auxiliary volume of the reactor, which is formed directly in the common chamber or in the form of an auxiliary chamber, is established on the basis of the specified technological regime - the residence time of the mobile foam in the reactor itself, the required degree of completion of its foaming and curing of the subsequent formation of the necessary profile from it.

When the coefficient of pore formation K = 2, i.e. when the end product is a low-porous product and the common chamber is capable of accommodating the intermediate product of its production, the auxiliary volume can be present in the common chamber itself. In this case, this auxiliary volume will simultaneously serve as the technological volume for carrying out the stage of manual mixing of the starting components.

An important feature of the claimed design is the set volume of the common chamber, which is set based on the requirements of the manual method of mixing the starting components and its versatility:

Vok = Vk / (0.1 ÷ 0.8), where Vok is the volume of the common chamber.

The most preferred and versatile from the standpoint of using a wide range of starting components is the design of the inventive reactor, in which the free auxiliary volume is created in the form of an auxiliary chamber connected to a common chamber for mixing the components. To carry out the process of forming the desired profile in the target product, the inventive extruder reactor comprises an outlet device in the form of a forming die, which at the time of storage of the reactor can be closed by a removable partition, a lid, a plug and formed in the auxiliary chamber. The latter can also serve as a die channel.

As an option of possible connection of the common mixing chamber with the auxiliary chamber, when the latter is significantly larger than the common chamber, and can be stored separately from the main part of the film reactor and / or serve as an external protection of the main chambers in which hazardous components are located, their temporary detachable connection, for example, according to the scheme "passage fitting - passage cap".

With relatively small amounts of the porous agent produced in the film reactor and, accordingly, the small size of the reactor itself, its most preferred embodiment is the shape of a "sleeve" in which the cross section of the reactor is several times smaller than its length (like a "sausage"); the common mixing chamber and the auxiliary chamber form this form by connecting through a removable partition, the serial circuit "auxiliary camera - main camera A and then camera B" or according to the scheme "auxiliary camera - main camera B and then camera A". Chambers A and B contain the starting components to obtain the target product - a porous agent.

In certain critical applications (for example, when obtaining therapeutic porous agents applied to a wound or fracture at the site of use outside the hospital environment), it is necessary to visually monitor the formation of the porous agent already at the stage of its preparation inside the container itself. To solve this problem, the inventive film reactor contains a transparent (for visual observation) auxiliary chamber, which is made, as a rule, of a single-layer transparent film material-polyethylene, polyethylene terephthalic, polyvinyl chloride, polyurethane and other known polymers and their copolymers of medical quality. At the same time, the transparency requirement for the auxiliary chamber may conflict with the requirement of the barrier properties that the main film chambers of the reactor should have, as well as with the requirements of manufacturability of the general design, with its manufacture from a single sheet-blank of the film material. The solution of this contradiction in the claimed design is carried out by performing a film reactor of the "sleeve in sleeve" type, in which the inner sleeve is transparent, contains the main and auxiliary chambers, has a total volume of at least equal to the volume of the moving porous mass formed in it, and the outer sleeve is made of a multilayer barrier material, has a length of at least equal to the sum of the lengths of the main chambers (containing the source components), is closed at least on one side (from the side of the main chamber) and covers the main chambers, leaving an auxiliary transparent, uncoated chamber for visual observation of the process of formation of the porous mass, or provides the ability to remove the inner sleeve from it at the time of receipt of the porous means. Moreover, both sleeves have transverse dimensions close in value and, accordingly, have a tight mutual fit. The implementation of the film reactor of the specified type allows you to give its design the proper barrier properties, to protect the environment from penetrating vapors of toxic starting components at the time of storage of the film reactor with toxic components in the inner single-layer with low barrier properties.

The inventive design of a film reactor-extruder makes it possible to combine the starting components in a common chamber with various manual mixing methods — crushing, crushing, shaking or shaking. Recent developments in shaking methods (used to mix liquid and powder components) and agitation (used for mixing liquid components) lead the authors of the present invention to include an additional chamber (s) in the inventive reactor. Such a chamber (s) is connected to the common chamber of the reactor through an additional removable partition, and if there are several additional chambers, they are also connected to each other through a separate removable partition. The additional chamber contains a thermally degradable substance or a low boiling product (the decomposition or boiling point ranges from 40 ° C to 80 ° C), and the additional chambers (when there are at least two) contain products that interact with the evolution of gas in an amount that provides form stability to the common chamber and the possibility of combining the main components (to obtain the target porous means) by the most intensive method of manual mixing - by shaking or shaking.

Almost any pair of solid and / or liquid substances can be used as initial gas-forming products to fill additional airtight chambers. When mixed, gaseous products (a separate gas or gas mixture) are released. The limitation in their selection is the permissible chemical activity of the starting products and the products of their interaction. They should not have an undesirable effect on the main components and on the target porous agent. Such gas-forming products include relatively strong acid paired with salts of carbonic acid, acids paired with metals, substances with free isocyanate groups (isocyanates) paired with water and catalytic additives, and others, if they do not violate the above restrictions.

Ammonium carbonate (decomposition temperature about 58 ° С) or acidic ammonium carbonate (decomposition temperature in the range of 40-60 ° С), etc. can be used as thermally degradable substances. A list of such substances can be selected from the chemist's reference books (see, for example, the Chemist's Reference Volume 2, published by Chemistry, 1967, Leningrad).

As low boiling substances, you can use hydrocarbons, ethers and esters, aldehydes, alcohols and others. Among these are hexane, ethyl acetate, acetone, dichloromethane, carbon tetrachloride, petroleum ether, methanol and ethanol (see also the specified Handbook. Volumes 1-6). The amount of substances used to form gaseous products is determined on the basis of the required volume of gas, which should provide the necessary chamber stability to the common chamber. The experiments showed that the required volume of gas in the common chamber, which is under its some excess pressure, should be from 0.1 to 1.0 volume parts of the total volume of the mixed main components.

The manufacture of the inventive film reactor-extruder of the "sleeve-in-sleeve" type opens up new possibilities for the created structure - its adaptation to obtain a movable porous mass inside the container and subsequent withdrawal of gaseous products formed in additional reactor chambers under excessive pressure. To realize this new feature, additional cameras are placed at the end of the outer sleeve, which in this case is hermetically attached to the inner sleeve outside the junction of the auxiliary camera (1) and the camera (2), if the length of the outer sleeve does not cover (according to visual inspection requirements) the auxiliary camera the reactor. Or, the outer sleeves are of sufficient length so that it covers the entire inner sleeve and its gas generating additional chambers. The gas generated in the additional chambers is removed from the common chamber for mixing (11 + 12) gas-forming substances or removed from one additional chamber (if thermally decomposed or low-boiling substances act as gas-forming agents) and exerts its pressure on the thin-film (single-layer, easily crushed) inner sleeve, t. e. to the common reaction chamber of the starting components, where by this time a mobile porous mass is already being formed. Under excessive gas pressure on the inner film sleeve, the moving porous mass is discharged either into the auxiliary chamber and then beyond the reactor through the forming die, or immediately outside the reactor through the forming die if the auxiliary chamber is not used in this technology and the auxiliary volume is formed in common camera. When the porous product being produced is characterized by a low apparent density, small openings (of the order of 1 mm in diameter) are made in the common chamber and / or in the auxiliary chamber to discharge an excess of pore-forming gas, or this excess gas is discharged through a filter nozzle of the reactor.

The die itself can be composite - the inner film sleeve and the outer (removable) rigid form-forming lining-box (various configurations).

BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 shows a sketch of the inventive film reactor-extruder, made in the form of a sleeve and containing two main film chambers (2 and 3), in which the main components (A and B) are stored, and containing an auxiliary film chamber (1) free from components. The chambers (1, 2 and 3) are connected with the help of sealing removable partitions (fragile or in the form of a mechanical clamp), respectively (5 and 8). The reactor also has an outlet channel made in the form of a die (round in the drawing) for withdrawing from it a moving porous mass of a given profile to the place of its curing and / or re-expansion and use. This channel may be closed by a lid or a partition during the storage of the reactor and until the target agent and pore-forming gas are discharged from it. The reactor is made welded from a film of polymeric material (polyethylene or others) or a multilayer film material with increased barrier properties with respect to the pairs of the main starting components A and / or B. It is advisable to manufacture the reactor from a single sheet of film material by folding it (according to a pattern) and welding to form a continuous weld (6).

Figure 2 shows a sketch of the inventive film reactor-extruder, made in the form of "sleeve in a sleeve" and containing an inner sleeve (chambers 1, 2 and 3) of a transparent single-layer polymer film material. The outer sleeve is made of a barrier multilayer film material (polyethylene-aluminum foil-polyethylene terephthalate, as an example). The outer sleeve covers the main chambers (2 and 3), in which toxic components A and B are stored (for example, polyol and isocyanate components to obtain a polyurethane porous agent - rigid or flexible polyurethane foam).

The auxiliary chamber (1) remains free of cover and accessible for visual observation of the formation of the porous agent.

Figure 3 shows a sketch of the inventive film reactor-extruder, made in the form of a sleeve when connected in series through removable baffles of the chambers (1, 2, 3) with an additional chamber for mixing auxiliary gas-generating substances (D and D). Additional chambers (11 and 12) are separated by a removable partition (13), in the drawing, by a brittle one, when removed, they form an additional chamber for mixing gas-forming substances (for example, to separate carbon dioxide when mixing citric acid powder and an aqueous solution of baking soda). The evolved gas enters under a certain excess pressure into the common mixing chamber (2 + 3) of the main components A and B and gives it the necessary form stability to carry out the process of combining the initial components A and B by shaking (if components A and B are powder and liquid) or by agitation (with components A and B - liquid and liquid). The porous movable mass formed occupies fully or partially the entire total volume of the film reactor (chambers 1, 2, 3, 11, and 12) and then it is squeezed out of the reactor through the die channel (4), for example, by folding its end part from the side of the chambers 11 and 12 (according to the type of extrusion of toothpaste from the tube).

Figure 4 shows a sketch of the inventive film reactor-extruder made in the form of "sleeve in a sleeve" in which the outer sleeve is made of a multi-layer vapor-tight film material having barrier properties with respect to the pairs of components A and B. The outer sleeve covers the film chambers (2 and 3), made of a single-layer film material (transparent if necessary) with insufficient barrier properties for long periods of storage of the film container until its actual use . The outer sleeve is hermetically attached (welded) with its outlet to the junction of chambers 1 and 2 (outside). The outer sleeve, in addition, has additional chambers 11 and 12 at its end, containing gas-forming substances G and D. When mixing substances G and D (for example, acid and carbonate) by eliminating the partition 13 (Figure 3), a chemical flows between the chambers 11 and 12 reaction with the evolution of gas (for example, carbon dioxide), which in turn presses on the common film chamber (2 + 3) of mixing the starting components and pushes the porous movable mass formed in it into the auxiliary chamber 1 and then beyond the reactor through a forming die to the place of its dovspenivaniya and / or post-curing and use (e.g., in hard or insulated sealable cavity).

Figure 5 shows a sketch of one embodiment of the inventive extruder reactor, in which the outer sleeve is made of a single-layer transparent film material. The outer sleeve (15) has a length equal to the sum of the lengths of the main chambers (2 and 3) and the free auxiliary chamber (16), which is formed in the outer sleeve. All chambers are connected in series and form a tubular form of the extruder reactor. The main chambers (2 and 3) containing toxic components A and B are made of a vapor barrier multilayer film material by welding on the inner (polyethylene) layer. The size of the main chambers is established based on the possibility of using various methods of manual mixing of the starting components (depending on their viscosity, compatibility and quantity). The outer sleeve from the side of the auxiliary volume (16) contains an outlet die (4).
