UHMWPE identification method: temperature measurements. Pure UHMWPE product quality polymer polyethylene wear block, at 200 degrees Celsius is not melted polymer polyethylene wear block, will not be deformed, but become soft. If it is not pure UHMWPE material at 200 degrees Celsius there will be deformed. Development of ultra high molecular weight polyethylene history: 1964 China successfully developed and put into industrial production; 975 Netherlands use decahydronaphthalene as solvent invented the gel spinning method successfully prepared UHMWPE fiber polymer polyethylene wear block wholesale and in 1979 he applied for a patent. After that through the efforts of a decade of research, confirmed gel spinning method is an effective method for manufacturing high-strength polyethylene fiber with industrial future.
