超高分子量耐磨抗老化聚乙烯板UHMWPE板

高分子聚乙烯板产品特点：

（1） 耐磨特性，抗滑动摩擦能力强。超高分子量聚乙烯板耐磨性高于一般的钢管4-7倍，不锈钢的27.3倍。是酚醛树脂的17.9倍，尼龙六的6倍，聚乙烯的4倍，年磨损率平均值0．58㎜ ,提高了管道的使用寿命。

（2） 耐冲击性，在现有的工程塑料中超高分子量聚乙烯的冲击韧性值高，其抗冲击强度常温下是PE100的10倍以上。随着环境温度的降低，其抗冲击性能越强。

（3） 耐腐蚀性能，能耐绝大多数腐蚀性介质和有机溶剂的侵蚀，超高分子量聚乙烯可以在浓度小于80%的浓盐酸中应用，在浓度小于75%的硫酸、浓度小于20%的硝酸中性能相当稳定。

（4） 自润性，自身滑动性能优于用油润滑的钢或黄铜。在环境恶劣、粉尘、泥沙多的地方，超高分子量聚乙烯管自身干润滑性能更好。能运动自如，保护相关工件不磨损或拉伤。摩擦系数只有0.07~0.12，是普通PE的1/5，新钢管的1/6，橡胶的1/20。

（5） 无毒性，超高分子量聚乙烯材料是环保材料，无毒无味、防污抗蛀新型热塑性工程塑料。允许它用于与食品接触的场合。中国许多城市的主供排水道管都改用超高分子量聚乙烯管。

（6）耐低温性、抗老化，超高分子量聚乙烯管可长期在-269℃到80℃的温度下工作，由于分子链中不饱和分子团很少，分子量大，稳定性高，老化速度特别缓慢，使用寿命加长。

（7） 表面非附着性、不结垢，超高分子量聚乙烯管由于摩擦系数小和无极性，具有表面非附着性。

（8） 抗开裂性优，超高分子量聚乙烯管通过拉伸试验证明，它具有100~300%的延伸率，在承受巨大的外压和内压时或者是弯曲应力也能保持一定的变形而不断裂。

Ultra high molecular weight wear-resistant and anti-aging polyethylene board UHMWPE board
Features of polymer polyethylene board products:
(1) Wear resistance and strong resistance to sliding friction. The wear resistance of ultra-high molecular weight polyethylene sheet is 4-7 times higher than that of ordinary steel pipes and 27.3 times higher than that of stainless steel. It is 17.9 times that of phenolic resin, 6 times that of nylon 6, and 4 times that of polyethylene, with an average annual wear rate of 0.58 mm, which improves the service life of the pipeline.
(2) Impact resistance: Among existing engineering plastics, ultra-high molecular weight polyethylene has a high impact toughness value, and its impact strength at room temperature is more than 10 times that of PE100. As the ambient temperature decreases, its impact resistance becomes stronger.
(3) Corrosion resistance, able to withstand the erosion of most corrosive media and organic solvents. Ultra high molecular weight polyethylene can be applied in concentrated hydrochloric acid with a concentration of less than 80%, and its performance is quite stable in sulfuric acid with a concentration of less than 75% and nitric acid with a concentration of less than 20%.

(4) Self lubrication and better sliding performance than steel or brass lubricated with oil. In areas with harsh environments, dust, and sediment, ultra-high molecular weight polyethylene pipes have better dry lubrication performance. Able to move freely and protect related workpieces from wear or strain. The friction coefficient is only 0.07~0.12, which is 1/5 of ordinary PE, 1/6 of new steel pipes, and 1/20 of rubber.
(5) Non toxic, ultra-high molecular weight polyethylene material is an environmentally friendly material that is non-toxic, odorless, stain resistant, and mothproof. It is a new type of thermoplastic engineering plastic. Allow it to be used in situations where it comes into contact with food. Many cities in China have switched to ultra-high molecular weight polyethylene pipes for their main water supply and drainage pipes.
(6) Low temperature resistance and aging resistance. Ultra high molecular weight polyethylene pipe can work at the temperature of -269 ℃ to 80 ℃ for a long time. Because there are few unsaturated molecular groups in the molecular chain, the molecular weight is large, the stability is high, the aging speed is particularly slow, and the service life is longer.
(7) Surface non adhesion and non scaling, ultra-high molecular weight polyethylene pipes have surface non adhesion due to their low friction coefficient and non polarity.
(8) Excellent crack resistance, ultra-high molecular weight polyethylene pipes have been proven through tensile tests to have an elongation of 100-300%, and can maintain a certain deformation without fracture under significant external and internal pressure or bending stress.

Application field of ultra-high molecular weight polyethylene sheet:


1. Ultra high molecular weight PE flame-retardant sheet, used for underground operations in coal mines and other places prone to spontaneous combustion.


2. Engineering uses ultra-high molecular weight PE sheets instead of steel, which have high wear resistance, chemical resistance, and corrosion resistance.


3. UHMW PE sheet can withstand low temperatures at low temperatures.


4. UHMW PE sheets can be placed in damp or deep water.


5. Ultra high molecular weight PE board should be exposed to sunlight for a long time without fading.


6. Ultra high molecular weight polyethylene sheets provide radiation protection in medical facilities.


7. Ultra high molecular weight PE board for food contact safety.


8. UHMW PE lining solution is used with low friction coefficient and no moisture absorption.
