宁津县鸿宝化工有限公司专业生产超高分子量聚乙烯链条导轨,我们拥有最先进的生产设备和加工设备,并且拥有最专业的设计和加工团队,为您提供最优质的产品和服务!
超高分子量聚乙烯板采用齐格勒型高效催化剂低压合成法,分子量根据需要控制在150-300以上。考虑到加工过程分子的热降解,因此具有粘均分子量大于170万的高密度聚乙烯加工成各种制品,才能更加具有优越性能。
1高耐磨性:在目前所有是工程塑料中UHMW-PE的耐磨性能最好,最引人注目。分子量越高材料就越耐磨,甚至超高许多金属材料(如碳钢、不锈钢、青铜等)。例如UHMW-PE管,在强腐蚀和高磨损条件下使用寿命是刚管的4-6倍,而且提高输送效率20%。充分展现了“节能、环保、经济、高效”的优越性。
2 耐腐蚀性:在碱液中不受腐蚀,在75%的浓硫酸、20%的硝酸中能稳定,它对海水、液体洗涤剂也很稳定。
3 极低的摩擦系数:静摩擦系数为007,自润滑性良好,是一种理想的轴承,轴套、滑块、衬里材料。选用UHMW-PE最为设备的摩擦部件,除可提高耐磨寿命外,还可以收到节能效果。
4 抗冲击性:抗冲击性居塑料之首,无论是外力强冲击,还是内部压力波动,都难以使其开裂。其冲击强度是尼龙66的10倍,聚氯乙烯的20倍,聚四氟乙烯的8倍,特别是在低温环境,其冲击强度反而达到最高值,其柔韧性能为输送系统提供了极为安全可靠的保障。
5 抗老化性:性能稳定,抗老化性好,地面、地下埋没均可,50年不老化。按ASTM方法 测定(负荷4.6kg/cm2),热变形温度为85℃,使用温度可达90℃,在特殊情况下,允许在更高的温度下使用。UHMW-PE是一种任性极好的材料,它的耐低温性能也非常优异,在-269℃低温下仍具有一定是延展性,而没有脆烈迹象。但线膨胀系数较大 ,导热性能很差,所以在设计制品时,要给予充分注意。
6 电性能:体积电阻大,击穿电压达50KV/mm。介电常数为2.3.在较宽的温度及频率范围内,适宜用作电气工程的结构材料。
7 卫生无毒:UHMW-PE无味、无毒、无臭,本身无腐蚀性,具有生理惰性和生理适应性。美国食品与药品管理局(FDA)和美国农业局(USDA)允许它用于与食品和药品接触的场合。
1 high abrasion resistance: in the present is all engineering plastic in uhmw-pe wear-resisting performance is best, the most notable. The higher the molecular weight of material is more wear-resisting, even many metal materials (such as carbon steel, stainless steel, bronze, etc.). Uhmw-pe pipe, for example, under the condition of strong corrosion and high wear life is just tube 4 to 6 times, and improve the transmission efficiency of 20%. To fully demonstrate the "energy saving, environmental protection, economic and efficient".
Corrosion resistance: from corrosion in lye, in 75% of sulfuric acid, nitric acid of 20% can be stable, it for sea water, liquid detergent is also stable.
3 extremely low coefficient of friction, static friction coefficient is 007, good self-lubrication, is an ideal bearings, bushings, slider, lining material. Selection of uhmw-pe most e friction parts, besides can improve the wear life, can also receive energy saving effect.
4 impact resistance, impact resistance among the top of the plastic, whether strong impact force, or internal pressure fluctuation, can make its cracking. The impact strength of nylon 66 is 10 times, 20 times of polyvinyl chloride (PVC), ptfe eight times, especially in low temperature environment, the impact strength maximum instead, its flexibility for conveying system provides a very safe and reliable protection.
5 aging resistance, stable performance, good aging resistance, ground, underground buried, aging in 50 years. According to ASTM method determination of 4.6 kg/cm2 (load), thermal deformation temperature 85 ℃, the temperature can reach 90 ℃, under special circumstances, allow use at higher temperatures. Uhmw-pe is a wayward excellent material, it also is very good, good low temperature resistance performance of the in - is still has some 269 ℃ low temperature ductility, without brittle signs. But larger linear expansion coefficient, heat conduction performance is very poor, so when designing products, to give full attention.
Performance: the volume resistance, the breakdown voltage of up to 50 kv/mm. Dielectric constant of 2.3 in relatively wide temperature and frequency range, suitable for electrical engineering structure materials.
7 health non-toxic: uhmw-pe tasteless, non-toxic, odourless, itself no corrosive, has physiological inertia and physiological adaptability. The us food and drug administration (FDA) and the United States of agriculture (USDA) allows it for special occasions in contact with the food and drug.
