Low pressure process is the core technology catalyst. TiCl4-Al (C2H5) 3 Germany Ziegler inventive structure formula polyethylene first generation of polyolefin catalysts, catalytic efficiency is low, per gram of titanium about thanks to kg of polyethylene. 1963 Belgian Solvay's first magnesium compound as the carrier of the second generation, the catalytic efficiency of titanium per gram to give tens of thousands to hundreds of thousands of g of polyethylene. Second generation catalyst also eliminates the need to remove catalyst residue after-treatment step. Fumed later developed highly efficient catalysts. In 1975, Italy developed into Montedison Group may be omitted and the direct production of granulated spherical catalyst polyethylene, known as the third generation of catalysts, high-density polyethylene produced yet another change. Chemical properties of polyethylene board (HDPE board) melting point of about 130 ℃, the relative density of 0.941 ~ 0.960. It has good heat resistance and cold Hubei polyethylene coal bin liner, chemical stability Shaanxi polyethylene coal bin liner, also has high rigidity and toughness polyethylene coal bin liner, good mechanical strength. Dielectric properties, resistance to environmental stress cracking resistance is also good. Melting temperature of 220 ~ 260C. Materials for the larger molecules, it is recommended melting temperature range between 200 ~ 250C.
