    Chemical plant corrosion is a common problem faced by chemical enterprises, reflecting lack of knowledge of corrosion prevention, small mistakes in equipment operation, often bring unexpected huge economic losses to enterprises.
    chemical plant corrosion can also be classified according to different principles. The anti-corrosion coating research room concluded that chemical plants can be divided into chemical corrosion and electrochemical corrosion according to the corrosion coefficient, according to environmental media can be divided into atmospheric corrosion, soil corrosion, non-electrolyte corrosion, gas corrosion, electrolyte corrosion, external current corrosion, contact corrosion, stress corrosion, frictional corrosion, biological corrosion, according to the form of corrosion can be divided into general corrosion, local corrosion and stress corrosion fracture. the main difference between
    chemical plant anti-corrosion coatings and conventional anti-corrosion coatings is that their high technical content, acid and alkali resistance technology is difficult, involving technological progress and product development, it is no longer too dependent on the knowledge and experience of coatings, ZS chemical plant anti-corrosion coatings it depends on electronics, physics, Ecology, machinery, instruments and management and other multidisciplinary knowledge and intersection, his technology comes from the synthesis of high resin resistance, high-efficiency dispersants and fluidizer applications, new anti-corrosion impermeable pigments and filler development, advanced and special test equipment and other supporting measures. Chemical plant anti-corrosion coating technology development also marks the development and upgrading of a company's scientific and technological technology level.
    in the chemical, petroleum, food, light industry and other industries, the vast majority of equipment, pipes due to the presence of corrosion media corrosion, corrosion media concentration, temperature changes at any time, so corrosion is very strict chemical plant. Coverings or linings made of a variety of corrosion-resistant materials can completely isolate metal equipment from corrosive media, prevent corrosion and abrasion of equipment, and improve corrosion resistance, wear resistance, safety and extended service life.
    China's chemical plant anti-corrosion coating research and development is very fast, in the traditional commonly used chemical plant corrosion-resistant coatings on the basis of the development of a number of excellent performance of new anti-corrosion coatings, and applied to practical engineering, practice has proved that these companies new anti-corrosion coatings excellent performance, some varieties of performance indicators have caught up with or exceeded the same kind of coatings abroad. The company developed ZS-811 high temperature anti-corrosion coatings that can withstand high temperature corrosion of 1800 degrees C, ZS-1033 anti-corrosion coatings that can withstand hydrofluoric acid, and ZS-822 compounds that can withstand corrosion of strong organic solvents and ultra-high temperature gas corrosion. High-temperature anti-corrosion coatings for ceramics, ZS-1041 anti-corrosion coatings that are specifically resistant to the strong corrosion friction of high-temperature flue gas and flue gas condensate, ZS-711 inorient anti-corrosion coatings that can withstand moisture corrosion in seawater and seawater, and acid-base-resistant coatings in various heat exchange equipment ZS-722 thermal anti-corrosion coatings, resistant to acid-base corrosion ZS-1031 anti-corrosion coatings under the impact of pressure-resistant friction, ZS-821 ceramic anti-corrosion coatings resistant to ether, fluorine, oil erosion and corrosion, etc., painted in deformation High-temperature acid-resistant ZS-833 flexible ceramic high-temperature anti-corrosion coatings, can withstand strong acid and alkali high temperature corrosion, especially nitric acid corrosion-resistant ZS-1032 anti-oxidation anti-corrosion coatings; Wide application prospects, market prospects, also chemical plant anti-corrosion experts.
    chemical plant anti-corrosion coatings, refers to relative to conventional anti-corrosion coatings, can be used in relatively harsh corrosion environments, and can achieve a longer protection period than conventional anti-corrosion coatings of a class of anti-corrosion coatings. ZS chemical plant anti-corrosion coating characteristics (1), can be used under harsh conditions, and has a long life of corrosion protection, chemical plant anti-corrosion coatings in the chemical atmosphere and marine environment, generally can be used for 10 years or more, even in acid, alkali, salt and solvent media, and at a certain temperature conditions, can be used for more than 5 years. (2), thick film is the chemical plant anti-corrosion coating chemical plant to mark. In general, the coating dry film thickness of anti-corrosion coating is about 100 m or 150 m, while the thickness of anti-corrosion coating film in chemical plants is more than 200 m or 300 m, and there are 500 m to 1000 m, or even up to 2000 m or more.
