Coating acid and alkali resistance test
Coating acid and alkali resistance test is a method used to evaluate the corrosion resistance performance of coatings in acidic and alkaline environments. In the test, the sample is exposed to an acidic or alkaline solution to simulate chemical corrosion conditions. After a period of exposure, observe whether the coating surface appears discoloration, flaking, corrosion and other phenomena to evaluate the chemical corrosion resistance of the coating. This test is very important in painting, chemical industry, metal protection and other fields to ensure that the coating can maintain stability in different chemical environments.

Introduction of emulsion paint light fastness and weathering resistance and acid alkalinity
The light fastness and weathering resistance of Pigment are important indicators to measure application performance. Especially in the case that indicators such as controlling fading have not been set in the exterior wall emulsion paint standard, understand the light fastness and weathering resistance of Pigment, choose light fastness and weathering resistance, and dilute the two Pigment with small performance changes is even more important.

Summary of standard detection methods for mass detection after painting
The quality of painting mass must ultimately be reflected in the advantages and disadvantages of film mass, so the mass detection after painting is mainly the detection of film performance, including the Mechanical Properties of film (such as Adhesion, flexibility, impact strength, Hardness, Gloss, etc.) and special performance with protection function (such as weathering resistance, acid alkalinity, oil resistance, etc.). The specific standard detection method is introduced below.
