Technical Field

[0001] This utility model relates to the field of polymer material processing technology, specifically to a pretreatment device for ultra-high molecular weight polyethylene sheet raw materials. Background Technology

[0002] Ultra-high molecular weight polyethylene (UHMWPE) sheets are engineering plastic sheets made from UHMWPE. They have extremely high molecular weight, which gives them excellent physical and chemical properties. UHMWPE sheets require pretreatment during processing to ensure the material's processing performance and quality.

The UHMWPE sheet raw materials are then transported to a mixing device for mixing. However, existing screening devices do not completely remove impurities, which affects the mechanical properties of the sheets. Furthermore, due to the poor flowability of the raw material powder, the existing mixing device does not mix evenly, and the pre-treatment process in the existing structure is dispersed, resulting in low efficiency.
