Problems solved by technology

[0002] At present, traditional coatings are generally used in architectural decoration. Most of the coatings are poor in corrosion resistance and water resistance, and their adhesion is average. , not waterproof, the paint film is easy to peel off as a whole after being washed by rainwater. At present, the influence of acid rain is increasing, which makes the requirements for the coating coating of buildings higher and higher. The waterproof and anti-corrosion problems of buildings are related to people. working and living environment, and affect the service life of the building
