Cov fibers hauv av yog cov fibers tau los ntawm cov pob zeb fibrous, feem ntau yog tsim los ntawm ntau yam oxides xws li silica, alumina, magnesium oxide, thiab lwm yam. Lawv cov khoom tseem ceeb yog ntau hom asbestos, xws li chrysotile asbestos, crocidolite, thiab lwm yam.

1. Txheej txheem cej luam ntawm cov khoom: Cov fibers minerals yog cov fibers tau los ntawm cov pob zeb fibrous minerals, feem ntau yog tsim los ntawm ntau yam oxides xws li silicon dioxide, txhuas oxide, magnesium oxide, thiab lwm yam. Lawv cov khoom tseem ceeb yog ntau hom asbestos, xws li chrysotile asbestos, crocidolite, thiab lwm yam.

2. Tsos: Fibrous

3. Kev Siv: Nws muaj kev sib kis zoo thiab tsim nyog rau kev sib tov nrog ntau hom kev sib tov. Cov khoom siv nres tsim los ntawm kev siv peb lub Hoobkas cov pob zeb cuav tsis muaj cov paj rwb pob zeb ntawm qhov chaw sib tsoo, thiab cov tsos ntawm cov khoom yog sib xws thiab sib xws nrog cov qauv zoo. Nruab nrog cov khoom siv tshwj xeeb rau kev sib cais cov pob slag hauv cov txheej txheem ntau lawm, cov ntsiab lus pob slag yog qis<3%, tom qab ua cov ntaub nres, lub suab nrov thaum lub sijhawm ua haujlwm tsawg.

4. Cov xwm txheej khaws cia thiab kev thauj mus los: Khaws cia rau qhov chaw qhuav, tsis txhob ntub dej, tsis txhob kub heev, thiab cais tawm ntawm cov kua qaub thiab alkalis.
