Description
Technical Field
The utility model relates to flame-retardant high-strength polyethylene blow molding equipment, and belongs to the technical field of blow molding film forming equipment.
Background
Polyethylene is a thermoplastic resin produced by polymerizing ethylene. Polyethylene is a crystalline thermoplastic resin. Their chemical structure, molecular weight, degree of polymerization and other properties are largely dependent on the polymerization process used. The polymerization process determines the type of branching and the degree of branching. Crystallinity depends on the degree of regularity of the molecular chains of the piece and the thermal history it experiences. One type of polyethylene plastic, the convenient bag we often mention is polyethylene. Polyethylene is the most simple polymer and is also the most widely used polymer material. Polyethylene is produced by the addition polymerization of ethylene. The properties of polyethylene depend on its mode of polymerization. The high-density polyethylene is polymerized under the catalysis of 15-30 atm organic compound. The polyethylene molecules polymerized under such conditions are linear and have very long molecular chains, up to several hundred thousand molecular weight. If free radical polymerization is carried out under the peroxide catalysis condition of 100-300MPa and 190-210C, the low density polyethylene is produced, and the low density polyethylene is of a branched chain compound structure.
