PE mentira membrana es una una vez consumible para la protección de los materiales crudos y descargados en el proceso.
PE lying film is the most widely used polymer material in the world today. It is formed by ethylene polymerization. The PE ionizing membrane is divided into high -density polyethylene, medium density polyethylene, and low -density polyethylene. Low -density polyethylene is soft, and high -pressure aggregation is used; high -density polyethylene has the characteristics of rigidity, hardness and mechanical strength, and multiple low -pressure aggregation. High -density polyethylene can be used as a container, pipeline, or a high -frequency electrical insulation material for radar and TV. A large amount of use is often low -density (high voltage) polyethylene. Polyethylene is waxy, has a wax -like smoothness. When it is not dyed, low density polyethylene is transparent, while high -density polyethylene opaque. Polyethylene is a bonus reaction and polymerization reaction of ethylene (CH2=CH2). High polymerization chain connected by -ch2-units. The performance of polyethylene depends on its aggregation method; the high-density polyethylene (HDPE) is made under medium pressure (15-30 atmospheric pressure) organic compound catalytic conditions. Polyethylene molecules of polymerization under this condition are linear, and the molecular chain is very long, with a molecular weight of hundreds of thousands. If it is a low-density polyethylene (LDPE) under high pressure (100-300MPa), high temperature (190–210 C), free radical aggregation under the catalytic conditions of peroxide, which is produced, which is a supporting structure.
