Problems solved by technology

[0004] Traditional heat-resistant anti-rust anti-corrosion primers have limitations in forming long-term anti-corrosion coatings on the surface of high-temperature metal components, and the coated objects are easy to rust and crack under high-temperature environmental conditions, especially in high-temperature pipelines and special facilities. It is very difficult to repair and repair after taking measures such as sleeves, and it is difficult to detect the degree of corrosion in the concealed part of the equipment during operation in a high-temperature and high-pressure environment, resulting in certain hidden safety hazards during operation
