Industrial heavy-duty anti-corrosion coatings generally refer to high-performance coatings that can be used in harsh industrial environments and have a longer anti-corrosion life than conventional anti-corrosion coatings. Industrial heavy-duty anticorrosive coatings can be used for more than 10 years in environments such as chemical atmospheres and marine environments. At a certain temperature, the service life can reach more than 5 years in solvent medium, acid, alkali, and salt. Generally speaking, industrial heavy-duty anti-corrosion coatings have the characteristics of high solid content, long weather resistance, excellent adhesion, convenient construction, thick coating construction, and strong comprehensive performance. And it also has certain temperature resistance, high toughness, high hardness, wear resistance and so on. It can ensure better construction in industrial areas, long-term protection of anti-corrosion life, and more convenient repair of some corroded areas.

　　With the development of industrial technology, from daily life to transportation, machinery, chemical industry, metallurgy, from science and technology to national defense industry, corrosion problems exist in every place where materials are used. The acid and alkali resistance of acid and alkali resistant anticorrosive coatings has become an important reference index in the anticorrosion industry. Coatings, especially acid and alkali resistant anticorrosive coatings, are very important for coating customers who need anticorrosion in special environments.

　　The following points should be paid attention to when applying industrial heavy-duty anti-corrosion coatings:

　　Choose a suitable heavy-duty anti-corrosion paint, which must be used in conjunction with the base, middle and top paint. Commonly used enamel bags for industrial heavy anti-corrosion are:

　　1. Bridge anti-corrosion engineering: cold spray zinc + sealant + epoxy mica intermediate paint + polyurethane top coat;

　　2. Steel structure anticorrosion engineering: epoxy zinc-rich primer + epoxy mica intermediate paint + acrylic polyurethane topcoat/fluorocarbon paint.

　　3. Anticorrosion of steel structures in power facilities and power plants: cold spray zinc paint + cold spray zinc seal paint + epoxy mica intermediate paint + polyurethane top paint.

　　The thickness of the coating must not only exceed the critical thickness, but also reach the appropriate thickness according to different anti-corrosion requirements. Thick film is an important feature of heavy-duty coatings. Generally, the dry film thickness of conventional anti-corrosion coatings is about 100 or 150 microns, while the dry film thickness of heavy-duty anti-corrosion coatings exceeds 200 or 300 microns, and some even reaches more than 500 microns. The thick protective coating also ensures the long-term anti-corrosion life of the coating.

　　requires strict coating pretreatment to meet the specified surface treatment standards. Before applying industrial anti-corrosion coatings, the surface of the steel structure must be cleaned, and the dirt on the surface of the steel structure must be cleaned with gauze or a rag. Ensure coating adhesion. The anti-rust paint in the middle should be evenly applied, and the paint should not be missed. After the intermediate paint is dry, apply acrylic polyurethane or fluorocarbon topcoat. The color must be consistent, the paint must be uniform, and the finished product must be protected.

　　The construction environment temperature of industrial anticorrosive coatings should be 0°C to 30°C. The relative humidity should be less than 85%. The construction should be carried out in a well-ventilated environment. Open flames and welding should be avoided. The surface temperature of the steel structure should also be higher than the dew point temperature by more than 3c.
