Description
Technical field
The invention belongs to emulsion demulsification leveling techniques fields, and in particular to a kind of quickly detection emulsion demulsification
The measuring device and its application method of change degree.
Background technique
The industrial emulsion liquid that China uses at present has a water-in-oil type emulsion and oil-in-water emulsion, and the latter is then more
The field for being widely used in industrial cutting field and being used as lubricant etc..In real process, inevitable phenomenon
It is oil-in-water emulsion in use since the friction by local ob causes amount of localized heat excessively high, demulsification can be encountered
Phenomenon, so that the film destruction of oil-in-water emulsion drop, the case where water-oil separating occurs, cause the performances such as its lubrication big
Big decline, leading to it can not secondary use, a more obvious phenomenon be again the emulsion uneven color after, and
Wherein there are many what minute bubbles can aoxidize emulsion to lead to its impaired performance for band.
By largely investigating, its reason is analyzed it was found that can be extensive by its emulsifiability by addition some emulsifier
It is multiple.But the degree of the part emulsifiability due to losing on existing industrial circle for the emulsion after use can not
The measurement centainly measured, cause to the additive additive amount of emulsion mostly be a biggish problem less.
Someone's report, the addition content of emulsifier and performance of emulsion itself have great linear relationship.However, with
The addition of emulsifier, the working performance of emulsion be gradually increased before this, but to not improving after certain peak value, can make instead
The internal structure of emulsion changes, so that emulsion is unable to reach working performance.Its reason is likely to, oil-in-water cream
Change liquid when no emulsifier or loss centainly due emulsifier, it may occur that certain demulsifying phenomenon causes to emulsify
Liquid water-oil separating, and then cause emulsion that qualitative change occurs, so that industrial operations can not carry out.
Also have in document and mention, since the loss of surfactants some in emulsion leads to demulsification, study carefully its essence
The reason is that the demulsification degree to emulsion not enough understands, it is unable to control the emulsifier for adding appropriate amount or respective additive or original
Liquid leads to that extra discharge is caused to waste.The cost of industrial investment is not only increased, more seriously increases and to dispose waste liquid
Cost, while inevitably pollution also is generated to environment to a certain extent.
It is relatively fewer about the method for measuring to emulsion resistance degree both at home and abroad.Standard GB/T7305-2003 and SH/
T0191-1992 repeatedly intake for oil product and oil-water ratio and experimentation in temperature design it is too single, do not meet reality
Situation.
Therefore apparatus for automatically measuring and the measuring method for researching and developing a kind of emulsion demulsification degree are very necessary.

Test solution container；And
Electrical connection or signal connect the control system of the laser machining device；
Wherein, the new liquid of emulsification refers to the brand-new emulsion being evenly distributed, as reference liquid, the old liquid of the emulsification
Refer to the emulsion of demulsification to be measured.
Preferably, the measuring device also includes: the display equipment being connect with control system.
Preferably, the display equipment includes LCD display or LED display.
Preferably, the test solution container is experiment ware.
Preferably, the experiment ware is fixed by the way that main body tank wall is arranged in the card slot activity on next door.

Preferably, the measuring device also includes: for controlling the temperature control device of the test solution vessel temp.
Preferably, the measuring device also includes: for preventing the case lid of ambient light interference.
The present invention also provides a kind of uses of measuring device according to above-mentioned quick detection emulsion demulsification degree
Method, this method include:
Step 1, the test solution container is taken out, hold the new liquid of emulsification respectively and emulsifies old liquid；
Step 2, the test solution container is respectively arranged in two accommodating spaces, the temperature needed is adjusted to by temperature control device
Degree；
Step 3, the laser machining device is opened by control system, carries out laser point to emulsifying new liquid or emulsifying old liquid
Optical scanning determines maximum absorption band wavelength；
Step 4, it is arranged above-mentioned maximum absorption band wavelength as laser testing wavelength in the laser emitter, to cream
Change new liquid and emulsify old liquid and carry out light transmittance test: the laser signal of laser transmitter projects is through the new liquid of Over emulsfication or the old liquid of emulsification
It is received again by laser pickoff, laser pickoff carries out photoelectric signal transformation to the laser signal received, and is sent to control system
System carries out light transmittance comparison, calculating and analysis by control system, obtains demulsification degree value.
Preferably, also including in step 4: before to emulsifying new liquid and emulsifying old liquid progress light transmittance test, in main body case
Upper capping case lid.
According to Lambert-Beer law, the light beam of certain wavelength period is predominantly absorbed by some after solution, and one
Part can then pass through.There can be the destruction of oil-in-water molecule after being demulsified according to emulsion, therefore there are the colorations of some suspension
Deep or shallow variation occurs.Original-pack emulsion before using is housed on the test ware of stationary barrier one end, the other end
Test ware is used to accommodate the emulsion destroyed using rear emulsifiability, after solution-stabilized, then covers case lid, in this way,
Laser emitter issues two kinds of test solutions of laser light by laser emission probe, and laser pickoff can then be visited by laser pick-off
Head is received through the light after test solution, is popped one's head in respectively with corresponding laser pick-off it should be noted that probe occurs for each laser
Position on main body case corresponds.Then each corresponding laser emitter light is projected by photoelectricity transformation principle to penetrate
Light transmission situation record after solution is in systems.It should be noted that several laser emitters are provided with altogether here, it is each
A laser emitter is corresponding with a laser emission point can penetration test ware.Since the uniformity and emulsifiability of new emulsion are excellent
Good property, therefore available new emulsion tests corresponding laser emitter outside ware and issues laser across new emulsion test ware
The light transmittance difference of corresponding position test solution everywhere is minimum；And in other side test ware it is the test solution after demulsification has occurred, it should
In test solution have some solvents and organic substance has occurred certain qualitative change or quantitative change, therefore laser pass through it is every after test ware test solution
The light transmittance of any is either large or small compared with passing through new emulsion centainly to have certain difference.We are saturating by each point
Light rate is compared with the light transmittance of stoste, makes each light transmittance curve analysis chart, can be obtained by mathematical interpolation calculating
The degree of each deviation of new old emulsion obtains emulsion demulsification degree in turn out.Here maximum demulsification degree value
For when measuring that water-oil separating is the most complete after corresponding solution to be measured be demulsified completely, thus the value measured also should new emulsion with
Between the complete demulsification degree of new emulsion, complete demulsification degree value is the light transmittance deviation measured at some laser probe
Maximum measured value at that.Certainly this is the light transmission feelings that laser generator sending laser records in a flash in solution
Condition, since there are mobility for solution, we can record deviation situation again every a bit of time, so to prevent one
There is contingency in the extent of deviation of kind situation, and test number (TN) usually says the test result that at least take three times, if measurement every time
The extent of deviation of the light transmittance almost larger difference of nothing out then illustrates that test data avoids the possibility of contingency generation, takes
Its average measurements.
It should be noted that knowing the result of the more tests of laser emission point number here more according to mathematical interpolation analysis
Accurately, and precision can be higher, is not described but still falls within the scope of the present invention here.It is another it should be noted that about right
Laser emitter issues the selection of the wavelength period of laser: can be by carrying out laser light splitting scanning to new emulsion in advance, generally
In the case of take out its maximum absorption band wavelength as subsequent laser testing wavelength, be because detection sensitivity at this time most
Height, the demulsification degree result that can finally measure can be more accurate.
It should be noted that if emulsion excessive concentration, may have that light transmission is more difficult, so before measuring
Certain proportion can be diluted to it, then on condition that the test solution of the new liquid of minimum demulsification degree and demulsification degree to be measured
Also corresponding dilution proportion is carried out, deionized water is preferably selected, demulsification journey is then obtained according to the extent of deviation of light transmittance
The bound of degree.
In addition, test ware lower section here is equipped with temperature control device, thus it is possible to vary the speed of the Brownian movement of different emulsions
Degree, it is also possible to change the measurement temperature of testing liquid.But the measurement of new emulsion and the emulsion of demulsification degree to be measured
Temperature setting unanimously will be measured generally by room temperature.It has measured every time another to measurement after a prepare liquid
Test ware is taken out cleaning treatment and completely renews prepare liquid by prepare liquid.
Beneficial effects of the present invention are as follows:
(1) device volume is small and exquisite brief, and test operation process is simple.
(2) it can adapt to the measurement of the demulsification degree of the emulsion in different range, resultant error is small, analyzes result
Real-time is preferable, high-efficient.

Condition needs and guarantees the stability during solution testing.
For measuring device of the invention centered on main body case, two laser emitters are mounted side by side on the side of main body case,
Two laser pickoffs are separately mounted to the other side of main body case.It should be noted that laser emitter and laser pickoff difference
There are several probes, the probe of laser emitter can issue laser beam respectively, and the probe of laser pickoff respectively can be with
Laser beam is received, a kind of pop one's head in the signal of six rows, five column spread pattern is only provided in Fig. 2, naturally it is also possible to design other
Distributed layout form.
It is stationary barrier among main body case, partition is mounted on middle in main body case, main body separator for container two sides and cabinet two
Middle is respectively provided with card slot in the shell of side, and effect is for placing fixed test ware, it should be noted that one sharing two here
A test ware, one is used to accommodate the excellent stoste of demulsification resistance, another is used to accommodate the higher old liquid of demulsification degree, needs
To illustrate that the position that depth of the prepare liquid of dress in test ware will at least exceed Laser emission and receiving transducer can sense
It sets, secondly it should be noted that the distance of laser pick-off probe distance test (DT) ware here is extremely close, prevents reception light from occurring to dissipate
It penetrates；Install the test ware of prepare liquid by card slot then can steadily fixed placement in main body case, it is specific as shown in Figure 1.
The generally hexahedron structure of ware 8 is tested, open at one end is upward, and test ware is long and wide length is big very compared with thickness
It is more, therefore the thickness for the experimental liquid that can be accommodated is naturally also relatively thin, to measure the deeper emulsion of some colors, because emulsion exists
When color is deeper, as long as dilution ratio is suitable, thickness it is enough it is thin can also have preferable translucency, used convenient for measurement emulsion
The comparison of the translucency of front and back can show the demulsification degree of emulsion indirectly after testing by light transmission.
It tests ware material and selects quartz glass, the reason is that its translucency is fine.
Temperature control device is installed below two test wares, all for giving test solution heating, the cream being convenient for measuring under different temperatures
Change liquid demulsification degree, tally with the actual situation needs.

In laser emitter and the signal of laser pickoff pass through and carry out circuit connection and being shown in digital display control with control system
On system screen.The different light of wavelength length can be issued by the light source of change laser emitter obtain different emulsions (difference
Test object) absorption peak optimal adaptation degree of absorption so that the absorption peak to peak value of emulsifiable concentrate and old liquid to be measured is more
Obviously, so reduce measurement result error.
Specific implementation process is as follows: two test wares 8 being taken out, the new liquid of emulsification is accommodated respectively and the old of demulsification occurs
Liquid, solution test ware 8 in submergence should ensure that the top laser can pass through solution, if emulsify new liquid coloration compared with
Height, laser are not easy to penetrate, then the dilution of certain multiple is carried out to it, and common extension rate can be determined according to eye-observation, subsequent institute
There is prepare liquid liquid equally to carry out the dilution processing of corresponding multiple；Then the test solution ware 8 equipped with solution is fixed in card slot 13, is beaten
It opens and adjusts the temperature to general room temperature with temperature control device 9；Power supply is opened after temperature is stable and solution-stabilized, is controlled by digital display
Screen is opened across the laser emitter 2 or 4 and laser pickoff 3 or 5 for emulsifying new liquid, and 11 pairs of digital display control flow controls are then passed through
System 10 carries out control and carries out laser light splitting scanning to the test solution, and (one Beer law of lambert, is point to Lambert-Beer law
The philosophy of light photometry is concentration and its liquid layer thickness for the power and extinction material for describing substance to a certain wavelength light absorption
Relationship between degree) it is principle, it determines maximum absorption band wavelength and as post laser test wavelength, is the laser inspection because at this time
It is best to survey sensitivity.Light transmittance is surveyed at absorption peak maximum wavelength, is minimum because of the influence of wavelength change at this time, and in other waves
Strong point, wavelength change influence big.Next it is arranged in laser emitter 2,4 with selected wavelength laser, to new and old emulsification
Liquid carries out the test of light transmittance, and case lid 12 is covered before test, prevents ambient light interference.Laser emitter 2,4 is simultaneously emitted by
Laser signal emulsified old liquid, the new liquid transmission of emulsification after, will be received in laser pickoff 3,5, and pass through optical telecommunications
Number conversion is delivered in the microprocessor of control system 10, passes through the light transmittance of the old liquid of emulsification and the light transmission of stoste (emulsifying new liquid)
Rate is compared, and makes each laser transmission point light transmittance curve analysis chart, then can be with the numerical interpolation analysis of computer
Obtain the light transmittance situation of each laser transmission point corresponding position of new old emulsion.In general, these processing of new emulsion
Numerical value afterwards is because of new emulsion evenness in a relatively more similar level；And the emulsion meeting after demulsification occurs
The transmitance of each point caused there are the phenomenon of coloration unevenness can have either large or small difference, so that at photoelectric conversion
There is biggish fluctuation deviation in numerical value after reason.By comparing the size of these deviations of new and old liquid so that it is determined that emulsion is broken
The size of emulsification degree.The size of these deviations of the new and old liquid refers to the average value for emulsifying new liquid and emulsifies old liquid
The deviation of average value.By analysis it is known that maximum demulsification degree is certain point in new old emulsion demulsification deviation
It is spaced maximum difference (emulsify new liquid and emulsify the maximum difference of old liquid), so that it is guaranteed that the demulsification degree of the old liquid measured
It can emulsify between new liquid and demulsification degree maximum emulsion.It, can be with by the maximum deviation degree of some laser transmission point
A general degree for knowing maximum demulsification, the demulsification degree liquid then measured is substantially within the scope of this.This
The determination that can be quantified stated on and, because having the old liquid of emulsification of the corresponding maximum demulsification degree of a upper limit, lower limit
Position is emulsifies new liquid, and other transmission point demulsification degree all can be between this.Certainly this is measuring for certain moment
Demulsification degree value should be obtained due to the mobility of solution every the laser testing that a bit of time re-records primary ibid process
New demulsification degree value；To prevent contingency, test result three times can be generally taken, if difference is little, illustrates to test
As a result good, then take its mean value as last demulsification degree value；If test result difference is larger, need to consider temperature or wavelength
The influence of selection or other factors to prepare liquid, general normal operating do not have too big influence.Case lid 12 is opened after the test,
Test ware 8 is taken out to be cleaned and handled clean.All laser emitters 2,4 and all laser pickoffs 3,5 are closed, are finally closed
Close power supply.
In conclusion being principle present invention utilizes Lambert-Beer law, to the demulsification degree of emulsion and thoroughly
Relationship between light rate has carried out test and has probed into, and verifies between them that there are certain linear relationships, thus new according to emulsification
Liquid and the light transmittance for emulsifying old liquid obtain the demulsification degree of emulsion.Specifically, the present invention selects the laser of suitable wavelength to examination
Liquid (emulsify new liquid and emulsify old liquid) is scanned analysis, and the light transmittance result of new old emulsion passes through photoelectric conversion and uses number
It learns interpolation analysis and compares the demulsification degree for obtaining old emulsion, achieve the purpose that automatic measurement.
