3PE anticorrosive steel pipe coating has good thermal insulation performance, 3PE anticorrosive steel pipe insulation performance is good, heat loss is only 25% of the traditional pipe, long-term operation can save relatively large resources, significantly reduce energy costs, and And still have relatively strong waterproof and corrosion resistance, and do not need to attach a pipe trench, can be directly bought into underground or water, in the construction is simple and rapid, comprehensive cost is also relatively low, at low temperature conditions is also good corrosion and impact resistance, and in a certain environment can also be straight Then buried in the frozen soil.【勝倉管業 高經理13730570531 QQ：2927372564】 Polyethylene three-layer protective layer, also known as 3PE anticorrosive steel pipe, is an advanced anticorrosive technology imported from abroad in recent years. Its full name is fused epoxy/extruded polyethylene structural protective layer, the structure is composed of three layers: the bottom layer is fused epoxy (>80 micron); the middle layer is adhesive (170-250 micron); the surface layer is extruded polyethylene (about 2 mm). 【勝倉管業 高經理13730570531 QQ：2927372564】The total thickness of the protective layer is about 1.8-3.7mm. In the three-layer structure, the main function of the fused epoxy powder coating is to form a continuous coating, which is directly bonded to the surface of the steel pipe, and has good chemical corrosion resistance and anti-peeling properties; react with the active groups of the interlayer adhesive to form chemical bonding, so as to ensure that the overall coating has good adhesion at higher temperatures. Nodding. 【勝倉管業 高經理13730570531 QQ：2927372564】Intermediate layer is usually copolymer binder, its main component is polyolefin, currently widely used vinyl copolymer adhesive. The functional groups of the copolymer adhesives can react with the epoxy groups of the fused epoxy powder coatings to form hydrogen bonds or chemical bonds, so that the intermediate layer and the bottom layer form a good bond; the non-reactive ethylene part has a good affinity with the surface layer polyethylene, so the intermediate layer and the surface layer also have a good bonding performance. 【勝倉管業 高經理13730570531 QQ：2927372564】The main function of the polyethylene surface is to protect the machine and prevent corrosion, which is the same as the traditional two-layer structure polyethylene coating.【勝倉管業 高經理13730570531 QQ：2927372564】
