The composition of 3-layer PE coating production line
The three -layer PE anticorrosion structure includes fusion bonded epoxy-powder bottom layer, polymer adhesive middle layer and polyethylene top layer. The so-called 3-layer PE Coating Production line,3-layer refers to the 3-layer structure of epoxy primer, that is a thermosetting, non-toxic coating, curing after form high molecular weight cross-linked structure coating, With excellent chemical corrosion resistance and high mechanical properties, especially the best wear resistance and adhesion. It can form a continuous coating and steel pipe surface directly bonded, with good resistance to chemical corrosion and anti-cathode stripping performance.
To ensure that the overall coating at a higher temperature Has a good adhesion, making the middle layer of adhesive reactive groups to form a chemical bond. That is high quality of steel pipe anti-corrosion coating buried in the ground.
The intermediate layer is usually a copolymer binder, the main component of which is polyolefin, and is widely used as a vinyl copolymer adhesive. The polar moiety of the copolymer adhesive and the epoxy group of the epoxy primer can react to form hydrogen bonds or chemical bonds to form a good bond between the intermediate layer and the substrate; and the non-polar ethylene moiety has a Good affinity, so the middle layer and the surface layer also has a good bonding performance. Three-layer structure of polyethylene anti-corrosion, as the buried pipe outside the protective layer is very superior, and the technology has been widely used in the West-East Gas and oil field oil supply, urban gas supply, water pipeline used on the anti-corrosion.
