Problems solved by technology

[0003] At present, although some anti-corrosion coatings are applied to chemical equipment, with the development of society, people put forward higher requirements for the performance of coatings used in chemical equipment. The existing coatings have corrosion resistance, high temperature resistance and flame retardancy. Poor, poor adhesion, easy to fall off during use, can no longer meet the needs of a rapidly developing society, and needs to be improved

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special high-performance coating for chemical equipment. Background technique [0002] 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 circumstances, due to the particularity of the environment in which chemical equipment is used, some oxidative-reductive gases and media are involved in the production of chemical companies. In addition, the production workshop has high humidity and high temperature, so it will A strong chemical reaction occurs on the surface of the equipment, resulting in corrosion. After being corroded, chemical equipmen...
