高分子量聚滑条 UHMWPE齿轮

 **高分子量聚刮板综合了如下优异性能：高性，高抗冲性，表面不粘性以及自润滑性。并且，即使低温条件下它亦能保持**的机械性能。高分子衬板是一种具有较高粘度的聚合物，为粉末形状，其典型粒径范围为100一200微米。由于粘度很高，它通常不能用普通的热塑性塑料成型方法来加工，而是用模压或柱塞挤出工艺，在高压下把**高分子量聚粒子熔融并烧结为坯材或型材，必要的话，再进行后续机加工。

  **高分子量聚板材产品特征：

  较好的性，良好的耐低温冲击性、自润滑性、无毒、耐水、耐化学药品性，耐热性优于一般PE，缺点是耐热性（热变形温度低、加工成型性差，外表面硬度，刚性，耐蠕变性不如一般工程塑料，膨胀系数偏大。UHMWPE流动性差，熔融状态下粘度较高，是呈橡胶状的高粘弹性体，早期仅能用压制和烧结方法成型，也可用挤出、注塑和吹塑方法加工。

机械性能**一般的高密度聚。具有**的抗冲击性、耐应力开裂性、耐高温蠕变性、低摩擦系数、自润滑性，**的耐化学腐蚀性、抗疲劳性、噪音阻尼性、耐核辐射性等。

UHMWPE scraper combines the following excellent properties: high abrasion resistance, high impact resistance, non sticky surface and self lubrication. Moreover, it can maintain excellent mechanical properties even under low temperature conditions. Polymer wear-resistant lining plate is a kind of polymer with extremely high viscosity, in the shape of powder, and its typical particle size range is 100-200 microns. Because of its high viscosity, it can not be processed by ordinary thermoplastic molding method, but by molding or plunger extrusion process. Under high pressure, ultra-high molecular weight polyethylene particles are melted and sintered into green materials or profiles. If necessary, subsequent machining is carried out.

Ultra high molecular weight polyethylene sheet product features:
  Excellent wear resistance, good low-temperature impact resistance, self lubrication, non-toxic, water resistance, chemical resistance, heat resistance is better than general PE, The disadvantages are heat resistance (low thermal deformation temperature, poor processing formability, lower external surface hardness, rigidity and creep resistance than general engineering plastics, and larger expansion coefficient. UHMWPE has poor fluidity, high viscosity in molten state, and is a rubber like high viscosity elastomer. In the early stage, it can only be formed by pressing and sintering methods, and can also be processed by extrusion, injection molding and blow molding methods.
  The mechanical properties are higher than those of ordinary HDPE. It has outstanding impact resistance, stress cracking resistance, high temperature creep resistance, low friction coefficient, self lubrication, excellent chemical corrosion resistance, fatigue resistance, noise damping, nuclear radiation resistance, etc.
