PE is ethylene by the polymerization of a thermoplastic resin

PE for short, is a kind of thermoplastic by polymerization of vinyl resin. In industry, including ethylene and small amounts of alpha olefin copolymer. Polyethylene odourless, non-toxic, feel like wax, has good low temperature resistance, The lowest temperature can reach - 70 - - 00℃) , chemical stability is good, most of the acid and alkali erosion can ( No acid) with characteristics of oxidation resistant Insoluble in common solvent, room temperature, small water imbibition, good electrical insulating performance; But polyethylene for environmental stress ( Chemical and mechanical effect) Is very sensitive, poor heat aging. From waste plastics recycling and processing of the pollution prevention into consideration, actively guide and support a batch of have the scale and level of waste plastics processing base, the phasing out of the factory, to improve the classification technology, will reduce the pollution to the environment of recovery processing of waste plastics. In order to realize technological progress will achieve a fundamental shift. In China most of the machines in surveying and mapping, or a little localization improvement, for surveying and mapping equipment is also a little knowledge, any change, no independent development research. Then again also easily recycled plastics, waste plastic in many places to be able to easily find, find the raw materials like plastic is your raw material price is very cheap, choose good plastic granulation machinery manufacturers also entrepreneurial success lay a solid foundation for you, is your good partner. Can be divided into thermosetting plastic and thermal plasticity, the former cannot remake used, which can repeat production. Plastic polymer structure, there are two basic types: the first kind is a linear structure, the polymer compound with this structure, known as linear polymer compounds; The second is body structure, has the structure of high polymer compound called shape high molecular compound. Some polymer with branched chain, called branched polymer, belongs to the linear structure. Although some polymer intermolecular crosslinking, but less crosslinking, known as the reticular structure, belongs to the body structure.
