Mainly through "four look":
A look at the colorful coating of aqueous solution after a period of storage, the pattern particles will sink, there will be a layer of protective colloidal water solution. This layer of protective glue solution, generally about 1/4 of the total amount of colorful paint. In the case of good quality and colorful coatings, the protective colloidal water solution is colorless or yellowish, and clear; and the poor quality of the colorful paint, the protective colloidal water solution is either more than 1/4 of the total amount of the colorful paint, or it is cloudy. The state is clearly presented with the same color as the pattern color particles. The main reason is that the stability of the colorful paint is not good, that is, the storage period has passed and it is not suitable for reuse.
Second, look at the floating objects where good quality and colorful coatings, in the surface of the protective colloidal water solution, there should normally be no floating objects, if there is a very small amount of color particles floating, it is normal; but if the number of floating objects is large, color particles are full The surface of the protective colloidal water solution, even with a certain thickness, is not normal, indicating that the quality of this colorful paint is poor.
Three to see the particle size to take a transparent glass, filled with half a glass of water, and then take a little colorful paint into the glass of water stirring. Wherever the paint is of good quality, the water in the cup is still clear, the particles are relatively independent in the clean water, there is no anion and cation that are bound together, the size of the particles is also very uniform, and the poor quality of the colorful paint, the water in the cup It will immediately become turbid, and the particle size will be polarized. A few of the large particles will be like cheeks, and most will be fine hairy particles.
Fourth, look at the sales price of all good quality and colorful coatings, are produced by the regular manufacturers according to the formula, the price is moderate; and poor quality of the colorful coatings, some manufacturers cut corners in production, and some even counterfeit personal production, low cost, sales price It is much cheaper than good quality and colorful paint.
