    Core tip: steel materials are widely used in construction, transportation, chemical industry, energy, electric power and other industries, and they are exposed to corrosive environment to varying degrees, so the corrosion of steel materials is a common problem There are many anti-corrosion methods for steel materials, and the most common method is to use anti-corrosion coating The market scale of anticorrosive coating is second only to that of architectural coating It is estimated that the market scale will exceed 1 million tons by 2020 The anticorrosive coating separates the protected material from the corrosive substances outside and plays the role of protecting the material Anticorrosive coating is generally divided into conventional anticorrosive coating and heavy anticorrosive coating routine 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 Coating home news: the use of steel materials in construction, transportation, chemical industry, energy, power and other industries is relatively large, and they are exposed to the corrosive environment to varying degrees, so the corrosion of steel materials is a relatively common problem There are many anti-corrosion methods for steel materials, and the most common method is to use anti-corrosion coating The market scale of anticorrosive coating is second only to that of architectural coating It is estimated that the market scale will exceed 1 million tons by 2020 The anticorrosive coating separates the protected material from the corrosive substances outside and plays the role of protecting the material Anticorrosive coating is generally divided into conventional anticorrosive coating and heavy anticorrosive coating Conventional anti-corrosion coating is a kind of anti-corrosion coating which can prevent metal from corrosion and prolong the service life of metal under general conditions; heavy anti-corrosion coating is a kind of anti-corrosion coating which can be applied in relatively harsh corrosion environment and has a longer protection period than conventional anti-corrosion coating Anticorrosive coating heat conduction anticorrosive coating is one of the best anticorrosive coatings It has many anticorrosive and heat conduction functions and high performance requirements Heat conducting and anticorrosive coating is mainly used on the outer wall or inner wall of oil tank and pipeline or less used in heat exchanger in petrochemical field The main reason is that all kinds of anti-corrosion coatings have their limitations in use, some can resist high temperature and corrosion, but not heat conduction, some can conduct heat but not oil, some have short service life, etc 722 thermal conductive anticorrosive coating adopts film-forming solution with high conductivity and filler with high heat transfer and high heat radiation The cured coating's conductivity (70 ℃) can reach 50W / m.k, and the thermal radiation coefficient of coating blackbody can reach 0.92 ε The heat exchange rate can be increased by more than 10% compared with the base material of 722 acid resistant thermal conductive anticorrosive coating, and can be increased by more than 50% in some materials It has excellent heat resistance and corrosion resistance It can resist the corrosion of acid, alkali, salt solution and organic solvent The maximum working temperature can reach 750 ℃ 722 acid resistant heat conduction anticorrosive coating has a high coefficient of thermal expansion The expansion and contraction energy of the coating keep the same when the temperature rises and falls repeatedly, and there will be no cracks or peeling off The ceramic functional filler composed of many components of 722 acid resistant heat conduction anticorrosive coating endows the coating with excellent wear resistance, thermal shock resistance and long-term resistance to air erosion, liquid erosion and powder friction [focus on WeChat official account "paint net"; pay attention to surprises, scan code to see if your husband is selling paint..
