Abstract
The invention discloses a measuring method for fineness of electrophoretic coating, comprising the following steps of: mixing the electrophoretic coating with butyl cellosolve in a ratio of 1:1; processing the mixed coating by using the ultrasonic vibration technology; afterwards, dropping the mixed coating on a fineness plate to carry out fineness test, wherein the measurement for the coating fineness is more precise by using surface tension and the ultrasonic technology; and the method is simple and practical.
Description
Technical field
The invention belongs to paint field, relate to a kind of measuring method of electrophoretic coating fineness particularly.
Background technology
The measuring process of existing electrophoretic coating fineness be adopt with electrophoretic coating and water according to 1: 1 mixed after, drip and on the fineness plate, directly carry out fineness and test.This kind method causes tested coating to be easy to generate bubble, and the bubble and the particle of generation are obscured, and because bubble is very small; Usually all be micron-sized, add because due to the coating self characteristics, the mixed viscosity of coating and water is still bigger; This kind minute bubbles are difficult for come-up, more difficult breaking.Mix when stirring the back and on the fineness plate, forming paint film, bubble can't break naturally, causes on the fineness plate and leaves bubble; Its form is identical with graininess on the fineness plate; The own particle of bubble and coating causes on fineness plate sightingpiston easily to be obscured, and can't make a distinction at all, and then cause erroneous judgement disconnected; Mistake is judged as particle with bubble, influences the accurate reading of fineness.
Existing method only is to use the water dilution, can not reduce dope viscosity and deface tension force; Adopt the standing methods bubble velocity very slow, can't discharge bubble at short notice at all.
Therefore a kind of measuring method that can make bubble float easily and break need be provided, and then obtain fineness more accurately.
Summary of the invention
The technical matters that the present invention will solve provides a kind of measuring method of electrophoretic coating fineness; This method is utilized surface tension and ultrasonic technology, can make that the measurement of coating fineness is more accurate; This method is simple, practical.
For solving the problems of the technologies described above, the present invention provides a kind of measuring method of electrophoretic coating fineness, may further comprise the steps:
Electrophoretic coating and butyl glycol ether are proportionally mixed at 1: 1;
Mixed coating is handled with vibration of ultrasonic wave;
Drip afterwards and on the fineness plate, carry out conventional fineness test.
It is to be placed in the supersonic wave cleaning machine 1 minute dilution coating is airtight that said vibration of ultrasonic wave is handled.
It is to adopt Shanghai High Kudos Science Instrument Co., Ltd. that said vibration of ultrasonic wave is handled, model SK2200H, and frequency of operation is 53KHZ.
The present invention has the following advantages:
1, the present invention adopts butyl glycol ether dilution coating to make dope viscosity lower, and the effect of deface tension force is bigger, makes bubble reduce;
2, adopt the vibration of ultrasonic wave technology, utilize the physical shock mode to improve intermolecular motion, quicken bubble floating and friction, improved the bubble speed of breaking, make micron-sizedly to be suspended in that bubble in the dilution coating is floating to break to liquid surface;
3, method of testing of the present invention adds the strong diluting solvent of dissolving power and disturbs to destroy its surface tension, and utilize the supersonic wave cleaning machine concussion under the prerequisite that does not influence coating concentration and characteristic, and the interior bubble floating upward quickly of coating is also broken naturally.
Embodiment
Use embodiment that the present invention is further specified below.

The qualified electrophoretic coating of sand milling is prepared two laboratory samples respectively; 1# is an electrophoretic coating: water=1: 1; The 2# sample is an electrophoretic coating: butyl glycol ether=1: 1, and these two samples to be done leave standstill the fineness test of carrying out the variant time period after the processing, experimental data is seen table 1:
The contrast of the present invention's technology and ordinary skill when table 1 leaves standstill
Embodiment 3
The qualified electrophoretic coating of sand milling is prepared two laboratory samples respectively; 1# is an electrophoretic coating: water=1: 1; The 2# sample is an electrophoretic coating: butyl glycol ether=1: 1 places supersonic wave cleaning machine (Shanghai High Kudos Science Instrument Co., Ltd., model: SK2200H with these two samples; Frequency of operation: carry out the fineness test of variant time period 53KHZ), experimental data is seen table 2:
The contrast of the present invention's technology and ordinary skill during table 2 ultrasonic oscillation
Can find out that from above-mentioned experimental result when leaving standstill equally, the present invention's fineness in the time of 5 minutes reaches 5 μ m; And ordinary skill needs 30 minutes; When using ultrasonic oscillation equally, the present invention's fineness in the time of 1 minute reaches 5 μ m; And ordinary skill needs 5 minutes.Sample fineness through diameter measurement method test of the present invention is identical with the fineness of existing test mode test, the existing routine measurement of comparing, and the measuring accuracy of fineness has improved a lot, and efficient improves a lot.
Obviously, the above embodiment of the present invention only be for clearly the present invention is described and is done for example, and be not to be qualification to embodiment of the present invention.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that technical scheme of the present invention extends out or change still are in protection scope of the present invention.
