Pail Mould is one of the objects of chemical production. The material of the chemical barrel is high-density polyethylene, also called low-pressure polyethylene, that is, HDPE. This material is not easy to weld with a plastic welding gun. You can use an iron sheet to burn the plastic of the same material on 1653, or use high-pressure Polyethylene [LDPE] or EVA plastic is hot, and this material is softer and has better toughness. At present, there is no glue to stick this material, and there is none in the world. If bonding is necessary, surface treatment must be done to stick it. . HDPE (High Density Polyethylene): HDPE is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance and can be used for packaging purposes. HDPE has good electrical properties, especially the high dielectric strength of the insulation, making it very suitable for wires and cables. Medium to high molecular weight grades have excellent impact resistance, which is the same at room temperature or even at low temperatures of -40F. The chemical plastic barrels use hollow-grade low-pressure polyethylene. There are many brands of such raw materials, from different origins and different origins. The use is different, the quality is also different, the factory often chooses the appropriate brand according to the product requirements.
