| Title | New Classification of PPGI Galvanized Steel Coil | ||||
| Description | Scratch resistant PPGI prepainted galvanized steel coil As cheap PPGI prepainted galvanized steel coil machining demand is higher and higher, coating in the guarantee of good flexibility, at the same time, need to improve the coating resistance and wear resistance, the existing technology adds polyamide powder in the coating formula, react with isocyanate in coatings, forming interpenetrating network system, to improve the surface roughness and hardness of the coating. Antibacterial PPGI prepainted galvanized steel coil Uses in household electrical appliances, food packaging, medical utensils antibacterial coating: mainly contains Ag+, the silver ion is the most effective antibacterial agent in nature, through zeolite as a carrier, release silver ion. Invades the cell body of the bacteria on the surface of the coating, cutting off its respiration. Disadvantages: the high cost of silver; Silver ion is unstable in the zeolite. Self-cleaning PPGI prepainted galvanized steel coil Self-cleaning coatings are generally divided into two categories: - surface hydrophilicity (true self-cleaning) - hydrophobic surface (lotus leaf effect surface, easy to clean) Hydrophilic surface coating Add hydrophilic auxiliary agent in the coating, coating after baking, the auxiliary agent float to the surface of the paint film, hydrophilic group hydrolyzed after water, make the coating surface hydrophilic, rain easy to wash off the attached layer and achieve self-cleaning. PPGI prepainted galvanized steel coil for cold roof Pigment powder in the paint can selectively absorb visible light, the rest of the reflected visible light is reflected as visual color. Cold roof paint Same color, different pigment powder, in the infrared camera, the display is completely different. Antistatic paint It is used in the production environment of electronic parts, food, optical equipment, medical facilities, etc Generally existing products: to coating antistatic auxiliaries or exposed metal surface. | ||||
