Problems with color-coated steel plates
Thread Content
Dear teachers, what is the difference between color-coated steel plates and ordinary steel plates? ? ? This post was last edited by bolinuser on 2008-1-6 15:46]
Color-coated steel sheets are made from cold-rolled steel plates; after degreasing, phosphating, and chromating, they are hot-dip galvanized on both sides under a nitrogen atmosphere. A chemical conversion coating is then applied to facilitate strong adhesion of the primer, followed by an epoxy resin primer, and finally a color topcoat resistant to chemical corrosion. Tests have shown that after being heated continuously for 96 hours in an oven at 120 degrees Celsius, there are no changes in the gloss or color of the coating surface, and the coating does not peel off after bending or stamping. Its excellent mechanical properties and corrosion resistance make it widely used in interior and exterior building decoration materials. The substrates for colored coated sheets can be divided into cold-rolled substrates, hot-dip galvanized substrates, and electro-galvanized substrates. The types of coatings for colored coated sheets can be divided into: polyester, silicone-modified polyester, polyvinylidene fluoride, and plastic sol. The colors of colored coated sheets can be varied according to customer requirements, including orange-yellow, creamy yellow, dark sky blue, ocean blue, crimson, brick red, ivory, porcelain blue, and more.
Thank you for your guidance; the answer is very comprehensive! ! !
Many of the existing buildings here have been converted to roofs made of metal panels. I understood it through the hero’s explanation.
The explanations on the 2nd floor are detailed; I learned a lot
Thank you for the advice! I finally understand how color-coated steel plates are processed
