4. Specification (size): 16 * 2.00mm (300m / roll) 20 * 2.00mm (300m / roll).
5. Advantages: soluble heat resistance, smooth inner wall, can effectively reduce noise, good creep resistance, long service life, clean and sanitary, strong high temperature resistance, very good thermal conductivity, strong corrosion resistance, flexible and easy to install, lg-988-hdpe second generation raw material resin, This kind of material is composed of ethylene and octene. In the process of polymerization, the position of copolymerization on the main chain and the density of short branch chain are controlled by molecular design, so that it has good high temperature resistance, long-lasting static voltage strength and excellent impact strength, and there is no need for cross-linking in the production process.
Density table: LDPE {low density} MDPE {medium density} HDPE {high density}
1. The base material used to produce our ham pe-xc pipe is HDPE (high density polyethylene). The 3-4 or 5-6-layer tubes are manufactured by CO extrusion of multi-layer precision sizing sleeves. Then, the post-treatment was carried out by electron beam crosslinking.
2. In this process, the macromolecular physical structures of plastics are connected to each other. It is characterized by high stability, high temperature resistance and durability. The central positioning of EVOH production process and the structure of the 5-layer oxygen barrier layer are particularly good protection for pe-xc pipeline and prevent mechanical damage
3. High density polyethylene (HDPE) is used as raw material for radiation crosslinking polyethylene pipe, and other auxiliary materials (such as antioxidant, etc.) are added. The tube (uncrosslinked) is extruded in a plastic extruder, and then the extruded uncrosslinked tube is cross-linked by high-energy radiation (electron beam or gamma ray) on the radiation device (electron accelerator or Co-60 irradiation station). The polyethylene pipe produced by this method is called radiation crosslinked polyethylene pipe (pexc pipe). Because radiation crosslinking is to use high-energy particles (β - γ - ray) to react with polyethylene to produce free radicals on the molecular chain of polyethylene, and the free radicals combine to form cross-linking bonds. Therefore, this crosslinking method does not need to add chemical crosslinking agents and catalysts, so the product has high purity, does not bring any harmful low molecular compounds, and there is no precipitation of low molecular substances in the process of use Contamination of the liquid being transported. At the same time, the high energy particles can degrade the polyethylene molecular chain. Therefore, the raw materials used should be easy to be crosslinked by radiation (crosslinkable materials), so as to reduce the degradation side effects caused by radiation and ensure the quality of products. At the same time, pexc pipe also has uniform crosslinking degree, high chemical purity and good sanitary performance, which is especially suitable for the transportation of high purity fluid such as pure water. Therefore, pexc pipe is a real green environmental protection pipe.
