How to judge the quality of paints?
After a period of storage of the colorful paint, the pattern particles will sink and there will be a layer of protective glue on it. This layer of glue solution generally accounts for about 1/4 of the total amount of paint. Where the quality of the paint is good, the protective adhesive aqueous solution is colorless or slightly yellow, and clear; while the poor quality paint coating, the protective adhesive aqueous solution is turbid, obviously showing the same color as the pattern color, the main problem is not The stability of the paint is poor, that is, the storage period has passed and should not be used any more. Methods and steps Look at the water After a period of storage of the colorful paint, the pattern particles will sink and there will be a layer of protective glue on it. This layer of glue solution generally accounts for about 1/4 of the total amount of paint. Where the quality of the paint is good, the protective adhesive aqueous solution is colorless or slightly yellow, and clear; while the poor quality paint coating, the protective adhesive aqueous solution is turbid, obviously showing the same color as the pattern color, the main problem is not The stability of the paint is poor, that is, the storage period has passed and should not be used any more. Look at the float Any good quality paint coating, on the surface of the protective glue aqueous solution, usually has no floating objects, and sometimes there are very few float particles floating, which is normal; but if the number of floating objects is large, even a certain thickness, it is not normal. . Look at the degree of particle Take a transparent glass and fill in a half cup of water. Then, take a little paint and stir it in the glass. Where the paint is of good quality, the water in the cup is still clearly bottomed out, the particles are relatively independent in clear water, and the size of the particles is very uniform. Look at the sales price Good quality paints and coatings are produced by regular manufacturers according to formula, and the price is moderate; while poor quality paints and coatings, some cut corners in production, and some even personal counterfeit production, low cost, good sales price than good quality paint Paint is much cheaper.
