Description

technical field [0001] The invention relates to the field of polymer material preparation, in particular to a preparation device and method for ultra-high molecular weight polyethylene sheets. Background technique [0002] The market potential of ultra-high molecular weight polyethylene sheet and sheet composite structural materials is huge. In the case of the same thickness, the weight of ultra-high molecular weight polyethylene high-strength sheet is only 1 / 8 of that of steel plate, its wear resistance is about 5 times higher, but its strength is equivalent, its corrosion resistance is better, and its impact strength is higher. Using ultra-high molecular weight polyethylene sheets to produce composite processing boards, composite pipes and composite profiles can build a basic industrial industry with the same scale as large steel factories, steel pipe factories, and profile factories. For example, many parts such as shells, fuel tanks, bumpers, fenders, bottom guards, and...
