The anti-corrosion coating of 3pe anticorrosive steel pipe is of vital importance for the life of buried pipes. Some pipes of the same material are buried underground for decades without corrosion, while others leak out in a few years.That's because they use different coatings.Polyethylene three-layer structure protection layer, also known as three-layer PE(3PE), is an advanced anti-corrosion technology introduced from abroad in recent years.Its full name is fused epoxy/extruded polyethylene structure protective layer, the structure is composed of the following three layers: its full name is fused epoxy/extruded polyethylene structure protective layer, the structure is composed of the following three layers: the bottom layer is fused epoxy (80 m);The middle layer is adhesive (170-250 m);The surface layer is extruded polyethylene (about 2mm).The total thickness of protective layer is about 1.8-3.7mm.In the three-layer structure, the main role of fused epoxy powder coating is to form a continuous coating film and directly bond with the surface of the steel tube, with good chemical corrosion resistance and anti-cathodic stripping performance;It reacts with the active group of the interlayer adhesive to form a chemical bond, which ensures that the overall anti-corrosion layer has a good bond at a high temperature.The interlayer is usually copolymer binder, the main component of which is polyolefin.The polar functional groups of the copolymer adhesive can react with the epoxy groups of the fused epoxy powder coating to form hydrogen bonds or chemical bonds, so as to form a good bond between the middle layer and the bottom layer.But the non-polar ethylene part and the surface layer polyethylene has the very good affinity to cooperate, therefore the intermediate layer and the surface layer also has the very good adhesive performance.Innovation is the soul of an enterprise and the guarantee of its sustainable development.Communicate more, complain less;Understand more and argue less.Running a business is the common operation of many links.Konosuke matsushita. Think more innovation, review more progress.The situation of the enterprise is very complicated, so he should have the courage and determination to break his arm, because this waiver reduces a lot of pressure and drag on him, making him more powerful and looking for better opportunities to develop.
