Problems solved by technology

[0004] At present, although some anti-corrosion coatings are applied to chemical equipment, with the development of society, people put forward higher requirements on the performance of chemical equipment. The high temperature resistance and corrosion resistance of existing coatings are not good, and the adhesion is not good. , it is easy to fall off during use, resulting in leakage. In severe cases, it will cause the shutdown of the production process, which not only causes economic losses, but also poses safety hazards

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special corrosion-resistant and high-temperature-resistant coating for chemical equipment. Background technique [0002] Corrosion is one of the main factors that lead to the damage of metal firmware. Corrosion problems will cause a lot of waste of resources and energy, pollute the environment, and more seriously, cause personal injury and death. The direct economic loss caused by metal corrosion accounts for about 2%-4% of the total output value of the national economy every year. [0003] With the development of our country's economy, the process of industrialization is gradually accelerating, and industry has become increasingly important to the development of the national economy. Chemical equipment is an indispensable part of industrial development, and its normal operation is directly related to the normal production and operation of engineering projects. Under normal ...
