多年来为了解决粘结堵仓问题,人们也想了许多办法:诸如在仓壁上贴瓷砖、铺钢板,用电锤击打,都未能彻底解决,且人工捅煤仓又时常造成人身伤亡事故。在北方寒冷地区的煤矿企业,冬季若防寒措施有限,容易发生含水份的物料和仓壁冻结在一起而造成的堵仓。所以经大量的调研和实验,最后决定采用 UHMWPE 板材为煤仓内衬,利用UHMWPE板材的自润滑性和不粘性,以降低摩擦系数,达到解决堵仓现象。
聚乙烯板材的性能优点:
1.高耐磨性:静摩擦系数为0.07;
2.自润滑性:表面光滑、无粗糙;
3.抗冲击性:抗冲击性能好无破坏;
4.耐腐蚀性:能耐磷酸、碱、盐类等的腐蚀 ;
5.不粘附性:表面张力小不易结垢;
6.抗静电性:抗静电系数10的3到6次方;
7.防紫外线:有效延长产品使用年限 ;
8.生无毒:无味、无毒、无臭,本身无腐蚀性,可用于与食品和药品接触;
9.重量轻:密度是0.93-。97,质地轻居工程塑料之首。;
10.抗老化:在正常日照条件下,50年不老化。
