General knowledge of coating: characteristics of anticorrosive coating

Core tip: in pipeline construction, people hope that the pipeline can be as durable as possible in various environments, especially in some chemical plants Therefore, the birth of anti-corrosion coating has become inevitable, and once listed, it has been favored by the public What is anticorrosive coating? Now let's introduce anticorrosive coating for you! Introduction of anticorrosive coating: Anticorrosive coating, generally divided into conventional anticorrosive coating and heavy anticorrosive coating, is an indispensable one in the paint coating Conventional anti-corrosion coating can prevent metal corrosion under general conditions; heavy anti-corrosion coating is relatively conventional anti-corrosion coating 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 Paint Home News: in the pipeline construction, people hope that the pipeline can be as durable as possible in various environments, especially in some chemical plants Therefore, the birth of anti-corrosion coating has become inevitable, and once listed, it has been favored by the public What is anticorrosive coating?
