Anti-corrosion coatings, generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, is an essential paint coatings. Conventional anti-corrosion coatings are in general conditions, such as metals to play a role in anti-corrosion, protection of non-ferrous metals to use the life; heavy-duty anti-corrosion coatings refers to the relative conventional anti-corrosion coatings, can be applied in relatively harsh corrosive environments, and has the ability to achieve a longer period of protection than the conventional anti-corrosion coatings a class of anticorrosion coatings.
Types of conventional anticorrosive paints
According to the use can be divided into: rubber anti-corrosion paint, marine anti-corrosion paint, metal anti-corrosion paint, automobile anti-corrosion paint, pipeline anti-corrosion paint, furniture with anti-corrosion paint, steel structure with anti-corrosion paint.
According to the resin film is divided into: epoxy anticorrosive paint, perchloroethylene anticorrosive paint, chlorinated rubber anticorrosive paint, polyurethane anticorrosive paint, acrylic anticorrosive paint, inorganic anticorrosive paint, high chlorinated polyethylene anticorrosive paint.
Anti-corrosion coating test items
1、Physical properties: appearance, transparency, color, adhesion, viscosity, fineness, ash, PH value, flash point, density, volume solids content, bonding strength, etc;
2、Construction performance: covering power, usage, consumption, drying time (surface drying, solid drying), film sanding, leveling, hanging, film thickness (wet film thickness, dry film thickness) and so on;
3、Chemical properties: water resistance, durability, acid and alkali resistance, corrosion resistance, weather resistance, heat resistance, low temperature test, chemical resistance;
4, harmful substances: VOC, benzene content, toluene, ethylbenzene, total xylene, free formaldehyde content, TDI and HDI content sum, glycol ether, heavy metal content (lead, mercury, chromium, cadmium, etc.);
5, electrical properties: electrical conductivity, breakdown voltage or breakdown strength, insulation resistance, dielectric constant, dielectric loss.
