Fiber ntau phaj siab phaj yog hom tshiab ntawm cov khoom tsim ua tsev. Raws li kev lag luam tus qauv ntawm lub tsev cov ntaub ntawv, nws yog cov tsis muaj asbestos thiab chrysotile fiber ntau cement tiaj tiaj phaj hauv lub tsev phaj. Tam sim no, feem ntau ntawm kev tsim khoom ntawm chrysotile fiber ntau cement siab phaj, cov khoom siv tseem ceeb fiber ntau cov roj ntsha silicon hmoov thiab lwm cov ntaub ntawv ntxiv, siv cov txheej txheem tshwj xeeb ntau lawm, los ntawm cov tshuab pulping thiab luam tawm tons ntawm presses siab kab kev kho cov txheej txheem tsim cov cement slab siv hauv kev tsim kho tau siv dav hauv ntau thaj chaw ntawm kev tsim kho rau nws txoj haujlwm zoo. Cov ntsiab lus tshwj xeeb ntawm cov fiber ua vaj huam sib luag pawg tsis yog tas mus li, thiab tuaj yeem txiav ua ntu zus raws li lawv tus kheej xav tau, lossis tuaj yeem kho raws li qhov kev xav tau.
Raws li cov khoom lag luam tshiab ib puag ncig lub tsev, calcium silicate board muaj qhov zoo ntawm tsoos fireproof board thiab ntxhia wool board, thiab muaj zoo dua fireproof kev ua tau zoo thiab kev pab lub neej ntev ntawm noo noo tsis kam. Nws tuaj yeem siv dav hauv hauv kev tsim khoom lag luam thiab kev lag luam engineering, qab nthab thiab kev faib tawm ntawm tsev. Phab ntsa, phab ntsa hauv qab rooj rau cov rooj tog hauv tsev kho kom zoo nkauj, phab ntsa txheej rau nkoj, muab faib phab ntsa rau cov tsev khaws khoom, phab ntsa vaj huam sib luag rau cov chaw nres tsheb, chaw ciav hlau, thiab lub raj tso pa tawm rau cov subways.
