Production core advantage of Prepainted galvanized steel coil, PPGI
Acid rain resistance:
Coating protection mechanism: acid rain is easy to form in an environment with industrial emissions or high levels of pollutants. The surface of pre-coated steel forms acid infiltration, which accelerates corrosion, forms blistering, peeling, etc.
anti-UV:
Coating protection mechanism: The coating of the pre-coated board will be powdered and deteriorated under ultraviolet rays or strong sunlight, showing discoloration and loss of gloss, and the paint will fall off quickly.
Humidity and heat resistance:
Coating protection mechanism: In a hot and humid environment, the high osmotic pressure of water vapor accelerates the penetration, forming the deterioration of the coating film, and then corroding the substrate, causing bubbles and peeling.
Low temperature resistance:
Coating protection mechanism: most paints can maintain stable processing performance above 0 degrees, but in high-cold areas, when the temperature is lower than 20-40 degrees, ordinary paints will become brittle, bend and crack, or even fall off, so the protection function is Completely lost.
Main features of PPGI and PPGL
1. Compared with galvanized steel, it has good durability and long life.
2. Good heat resistance, less discoloration at high temperature than galvanized steel.
3. Good heat reflectivity.
4. Processability and spraying performance are similar to those of galvanized steel.
5. Good welding performance.
6. Good cost performance, durable performance and very competitive price.
