非石棉矿物纤维作为石棉的代用品,目前已开发100多种,分为天然矿物纤维和人造纤维两类,前者如毛沸石(erionite)、丝光沸石(mordenite)、硅灰石(Wollastonite)、粘土纤维(如坡缕石polygorskite、海泡石sepiolite、绿坡缕石(attapulgite);后者如玻璃纤维、岩棉、矿棉、陶土纤维等。由于非石棉矿物纤维的化学组成与石棉纤维相似,因此对其致病性给予高度的重视。 (一)非石棉矿物纤维的体外效应
Non-asbestos mineral fibers as a substitute for asbestos, has been developed more than 100 kinds, divided into two types of natural mineral fibers and rayon, the former as erionite, mordenite, wollastonite, clay Fibers such as polygorskite, sepiolite and attapulgite, the latter such as glass fiber, rock wool, mineral wool, clay fibers, etc. Since the non-asbestos mineral fibers have a chemical composition similar to that of asbestos fibers, Therefore, its pathogenicity give a high degree of attention. (A) non-asbestos mineral fiber in vitro effects
