Ultrahigh molecular weight polyethylene (UHMW-PE) is integrated performance engineering thermoplastics having a linear structure. UHMWPE its development is very rapid, polyethylene board company 80 years ago, the world's average annual growth rate of 8.5%, after the 1980s, the growth rate as high as 15% to 20%. Moreover, China's average annual growth rate of over 30%. World consumption in 1978 was 12 Hefei polyethylene sheet, 000 to 12,500 tons, while in 1990 the world demand of about 50,000 tons, of which the United States accounted for 70%. 2007-2009 China has gradually become the world's plastics factory, ultra-molecular-weight polyethylene industrial development is very rapid, the following history: the 1930s, it was first put forward on the basis of ultra-high molecular weight polyethylene fiber theory; gel spinning appear plasticized spinning method and make a major breakthrough ultra-high molecular weight polyethylene technically; the 1970s, the University of Leeds Capaccio and Ward first developed a molecular weight of 100,000 molecular weight polyethylene fiber; roll Molding is a solid state processing methods, i.e., ultra high molecular weight polyethylene (UHMW-PE) below the melting point exert a great pressure polyethylene sheet, by particle deformation, effectively particles and particle fusion. The main device is a rotating wheel and a bow slider with a spiral groove with tongue and groove and tongue and groove with vertical grooves. Effective use of the friction material and the polyethylene sheet processing between the wall in the process, the pressure is sufficient to produce the ultra-high molecular weight polyethylene (UHMW-PE) particles are deformed. At the base end of the branch is equipped with heating units, after die extrusion materials. As will this roll device combined with an extruder, can process continuous.
