Common knowledge of coating: Analysis on the cause of discoloration of epoxy floor coating

Core tip: in some common places, we often see the phenomenon of gradual color change of floor paint How do these phenomena occur? Here is an analysis of the reasons for you: 1 Due to the different density of several pigments in the epoxy floor paint, during the storage process, the heavy pigments will gradually sink, and the light pigments will gradually float Therefore, if the epoxy floor coating is not stirred evenly when used, it will be inconsistent with the original color after the completion of the floor coating As long as the coating is well mixed before construction 2 Cleaning of epoxy floor paint with high acid value Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Home of paint news: in some common places, we often see some floor paint gradually changing color phenomenon, how are these phenomena produced? The following is to analyze the reasons for you: 1 Due to the different density of several pigments in epoxy floor paint, during the storage process, heavy pigments will gradually sink, and light pigments should gradually rise Therefore, if the epoxy floor coating is not stirred evenly when used, it will be inconsistent with the original color after the completion of the floor coating As long as the coating is well mixed before construction 2 The varnish with high acid value in the epoxy floor paint is easy to react with the iron packaging barrel, which makes the transparency of the epoxy varnish reduce, resulting in the darkening of the color Do not pack the paint with high acid value in iron 3 The heat resistance and light resistance of some pigments are not good, and some resins have poor weather resistance They are easy to turn yellow when exposed to light, especially in epoxy coatings 4 If the metal powder pigment is corroded by the residual free acid in the epoxy paint during storage, it will easily lead to blackening or green light 5 Some of the pigments in epoxy floor paint will change chemically, lose the inherent coloring power of the pigments, and cause fading or discoloration Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
