Pay attention to the "four look" when buying paint

In recent years, the use of colorful paints has increased in home decoration. However, the quality of the colorful paints currently on the market is large, and the advantages and disadvantages coexist. Therefore, you should carefully identify when you purchase, to prevent being deceived.

Mainly through the "four look":

A look at the aqueous solution of the colorful paint after a period of storage, the pattern particles will sink, there will be a layer of protective glue on the water. This layer of protective glue solution generally accounts for about 1/4 of the total amount of colorful coatings. Where the quality of the colorful paint, the protective adhesive aqueous solution is colorless or slightly yellow, and clear; and the poor quality of the colorful paint, the protective adhesive aqueous solution is greatly more than 1 / 4 of the total amount of colorful paint, or turbid The state clearly shows the same color as the pattern color. The main reason is not that the stability of the colorful paint is poor, that is, the storage period has passed and it is not suitable for use.

Second, look at floating objects. Any kind of colorful paint with good quality, there should be no floating objects on the surface of the protective glue aqueous solution. If there is a small amount of float particles, it is normal; but if the number of floating objects is large, the color particles are full. The surface of the protective glue aqueous solution, even a certain thickness, is not normal, indicating that the quality of such a colorful paint is poor.

Third, look at the particle size, take a transparent glass, fill a half cup of water, and then take a little colorful paint into the glass of water to stir. Where the quality of the colorful paint, the water in the cup is still clearly bottomed, the particles are relatively independent in the clear water, there is no anion and cation bonded together, the particle size 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 small number of large particles are like facial paralysis, and most of them are fine particles with fluff.

Four look at the sales price Where the quality of the colorful paints are produced by the regular manufacturers according to the formula, the price is moderate; and the poor quality of the colorful paint, some manufacturers cut corners in production, and some even personal counterfeit production, low cost, sales price It is much cheaper than a good quality colorful paint. Therefore, you should look for quality when purchasing, and don't want to be cheap.
