The epoxy resin powder bottom layer, the polymer adhesive intermediate layer and the polyethylene surface layer, wherein the epoxy powder bottom layer functions to form a continuous coating film, which adheres to the surface of the steel pipe and solidifies to provide good adhesion and has good adhesion. Chemical resistance and resistance to cathodic disbondment; the role of the polymer adhesive is to fuse with the epoxy powder coating before bonding, and bond with the outer polyethylene layer to make the three layers as a whole, the outermost layer is generally selected Medium-high density polyethylene (polypropylene is used in foreign countries), so the three-layer anti-corrosion structure combines the adhesion and anti-corrosion properties of epoxy powder with the weather resistance and mechanical damage of polyethylene layer, making up for their respective shortcomings. Increased coating life.
Three-layer PE anti-corrosion structure:
The first layer of epoxy powder (FBE > 100 um), the second layer of adhesive (AD) 170 ~ 250 um, the third layer of polyethylene (PE) 2.5 ~ 3.7 mm. The three materials are integrated and firmly combined with the steel tube to form an excellent anti-corrosion layer.
