The main characteristics of polyethylene sheet, odorless, non-toxic, feel like wax, has excellent low temperature properties (lowest temperature up to -70 ~ -100 ℃), good chemical stability, resistance to most acid-base erosion (impatience with oxidation properties of acid) coal bin liner, room temperature, soluble in common solvents Inner Mongolia coal bin liner, water absorption, excellent electrical insulation properties; low density; toughness (also applies to low temperatures); stretching is good; electrical and dielectric insulation is good; low water absorption; water vapor permeability is low; good chemical stability; tensile properties; non-toxic and harmless. However, PE sheet for environmental stress (chemical and mechanical action) is very sensitive, heat aging resistance is poor. Applications medical equipment parts, seals, cutting board, sliding profiles. Widely used in chemical, machinery, electricity, clothing, packaging, food, environmental protection, textiles and other industries. Widely used in gas transmission, water supply, sewerage, irrigation, mining and transport of fine solid particles, as well as oil, chemicals, and postal and telecommunications and other fields Yinchuan coal bin liner, especially in the gas distribution has been widely used. Structure of polyethylene molecule is a long chain linear structure or branched structure, typical of a crystalline polymer. In the solid state, the crystalline portion and amorphous coexist. Crystallinity depending on the processing conditions and raw processing conditions vary, in general, the greater the density of high crystallinity. L.DP E crystallinity is generally 55% - 6 5%, HDPF degree of crystallinity of 80% -90%. Figure 2-1 shows the schematic structure of PE. Seen from the figure, PE molecules have a certain degree of branching. The LDPE branched high. 15 ^ -25 containing side chains as well as small amounts of methyl and butyl side chains per 1000 carbon atoms, due to reduced side-chain or branched molecular regularity, so Anyang coal bin liner, will contain a lot of support PE chain crystallinity, density and rigidity are low. HDPE branched low per 1000 main chain carbon atoms only 5-7 ethyl side chain, and therefore high crystallinity, density, rigidity and hardness properties are good. Depends on the degree of polymer molecular weight, degree of branching and crystallinity, such as elongation at break depends on high-density PE and crystallinity degree, its mechanical properties like, but ductility poor, so understanding polymer structure will be of great help · modified and other modified its structure in general H DPE tensile strength of 20 to 25MPa, while LDPE tensile strength of only 10-2f5MPa. The value of the tensile strength of the material from the project (100 -200MPa) also differ a great distance.
