    Anti-corrosion coating is a coating coating that cures dense coatings, avoids corrosion of acids, alkalis and various substances on materials, and is an important branch of coatings. Anti-corrosion coatings are the most effective, economical and widely used methods to protect materials. Among them, Zhisheng Weihua heavy anti-corrosion coating refers to the relatively conventional anti-corrosion coatings, can be applied in a relatively harsh corrosion environment, and can achieve a longer protection period than conventional anti-corrosion coatings of a class of anti-corrosion coatings.
    anti-corrosion coatings consist of substrates, pigments, solvents and additives, and their corrosion and durability are related to substrate types, substrate pre-treatment, curing, coating thickness, bonding force between coatings and substrates, and some external environmental factors. Understanding the interaction of the components in the coating system, the physical and chemical causes of corrosion failure of anti-corrosion coatings, is the basis for the development of new anti-corrosion coatings.
    the development status of corrosion-resistant anti-corrosion coatings
    The protective concept of anti-corrosion coatings for metal materials mainly includes shielding, corrosion protection, cathode protection and the comprehensive protection of the above three methods.
    shielding is the most basic protection mechanism of anti-corrosion coating, it forms an inert isolation layer on the surface of the protected object, isolates the metal material from the connected environment, and contains the contact between the corrosive media such as water, oxygen and chloride ions in the environment, thus preventing corrosion reaction from occurring. This effect of anti-corrosion coatings depends on the thickness of the anti-corrosion layer, the tightness of the film and the stability of the coating. The corrosion-reprieve effect of anti-corrosion coatings is to create a protective film on the metal surface, such as a phosphate film or a passivated metal surface, thus protecting the metal. It is mainly rust-proof pigments that can act as passivation and phosphation on metal surfaces. Zhisheng Weihua anti-corrosion coatings grew into anti-corrosion paint industry standard, ZS anti-corrosion coatings more use of anti-corrosion conditions, anti-corrosion effect of good long-term corrosion resistance, has been recognized by the national project anti-corrosion. With the development of industrial technology, corrosion and corrosion protection are common in petrochemical, energy, power, metallurgy, aerospace and other fields.
    Domestic large-scale anti-corrosion coating enterprises, Beijing Zhisheng Weihua Chemical Co., Ltd., in the inorgic anti-corrosion coating research and development, the company after more than ten years of research and development of inororal polymerization technology has been in the forefront of the world, Beijing Zhisheng Weihua Chemical Co., Ltd. research and development can withstand 2300 degrees C high temperature corrosion ZS-811 high temperature anti-corrosion coating, ZS-822 composite ceramic high temperature anti-corrosion coating, temperature resistance can reach 1600 degrees C, high high temperature antioxidant capacity, high purity and non-volatile, it can withstand strong solvents and mixed solvents long-term immersion; ZS-1033 anti-corrosion coatings resistant to hydrofluoric acid, ZS-1041 anti-corrosion coatings that are specifically resistant to high temperature flue gas and strong corrosion friction of flue gas condensate; ZS-1042 Desulfurized special anti-corrosion coating, anti-impact anti-sulfur solution acid-base corrosion, ZS-711 inorgable anti-corrosion coating that can withstand seawater and sea water moisture corrosion, can increase the heat exchange anti-corrosion coating ZS-722 thermal anti-corrosion coating Resistance to corrosion of ZS-1031 anti-corrosion coatings under the impact of strong friction, ZS-821 ceramic anti-corrosion coatings that can withstand erosion and corrosion of ethers, fluorines, oils, etc., ZS-1034 anti-corrosion coatings resistant to most acid-base corrosion, solvents, intermediate media, etc., Acid strong oxidation corrosion ZS-1032 anti-oxidation anti-corrosion coatings, resistance to oxidation corrosion at 3000 high temperature ZS-1023 anti-oxidation anti-corrosion coatings,
    China's "13th Five-Year Plan" period, anti-corrosion coatings will enter the golden period of development and growth, its size, variety, performance will be greatly improved. With The development of China's infrastructure construction, industrial institution adjustment and emerging industries, anti-corrosion coatings have undoubtedly become an important field and branch of the coating industry and market system, and their related participating enterprises, technology development, product system, market size, actual demand, application areas, role play, etc. have reached a new level at present, and many industry experts believe that industrial coatings manufacturing scale is the most leading, high production efficiency, good production capacity, when anti-corrosion coatings.
