Asbestos Bulk Bag

Asbestos, tseem hu ua" asbestos fiber", yog ib lo lus dav dav rau qee yam silicate minerals uas tuaj yeem faib ua elastic fiber ntau. Cov tshuaj formula: 3MgO·2SiO2·2H2O, fibrous, ntsuab-daj los yog dawb, dawb thaum sib cais rau hauv pab yaj, silky luster, elastic fiber, asbestos muaj acid, alkali thiab kub tsis kam, tab sis kuj kub thiab hluav taws xob tsis zoo conductor. Cov fibers ntev dua yog siv los ua cov khoom siv hluav taws xob, xws li asbestos hlua, asbestos daim kab xev, ntaub asbestos, thiab lwm yam; luv fibers yog siv los ua asbestos cement khoom, asbestos suab rwb thaiv tsev cov ntaub ntawv, asbestos thermal rwb thaiv tsev cov ntaub ntawv (asbestos magnesium carbonate thermal rwb thaiv tsev hmoov) thiab tsawg rwb thaiv tsev cov ntaub ntawv rau voltage khoom, thiab lwm yam. Asbestos ua ib tug loj npaum li cas ntawm hmoov av nyob rau hauv cov txheej txheem ntawm mining. thiab siv, uas tuaj yeem ua rau tib neeg lub cev puas tsuaj rau ntau txoj hauv kev, thiab yuav tsum tau them nyiaj rau kev tiv thaiv kom muaj zog.

Kev thov tshwj xeeb ntawm asbestos

Asbestos fibers tuaj yeem woven rau hauv xov paj, xov, hlua, ntaub, ntim, thiab lwm yam, raws li cov ntaub ntawv los yog hauv ob sab phlu rau kev sib kis, tiv thaiv tshav kub, rwb thaiv tsev kub, rwb thaiv tsev thiab lwm yam khoom. Hauv kev tsim kho, lawv tsuas yog siv los ua asbestos boards thiab asbestos ntawv hluav taws kub boards. Rwb thaiv tsev kav thiab kiln mats, thiab cov ntaub ntawv xws li kev txuag hluav taws xob, kev tiv thaiv tshav kub, rwb thaiv tsev thiab suab rwb thaiv tsev. Asbestos fiber ntau tuaj yeem tov nrog cov cement los ua cov khoom asbestos cement xws li asbestos cement vuas, boards, ru tsev slabs, thiab asbestos kav. Asbestos thiab asphalt tuaj yeem sib xyaw ua cov khoom asbestos asphalt, xws li asbestos asphalt board, ntaub (linoleum), ntawv, cib, thiab kua asbestos xim, putty rau cement pavement thiab expansion tawg, thiab lwm yam, uas yog siv los ua waterproofing, khoom siv. rau kev txuag hluav taws xob, rwb thaiv tsev, kua qaub thiab alkali tsis kam, thiab cov khoom siv rau kev tsim kho tsheb. Rau lub teb chaws tiv thaiv, asbestos yog bonded nrog phenolic, polypropylene thiab lwm yam yas, uas yuav ua tau rau hauv anti-ablative cov ntaub ntawv rau foob pob ua ntxaij, aircraft tis, roj tso tsheb hlau luam, foob pob ua ntxaij tail nozzle raj thiab torpedo high-speed launchers, ships, tsheb, aircraft, tank, thiab nkoj. Lub suab rwb thaiv tsev thiab cov ntaub ntawv rwb thaiv tsev kub, asbestos thiab ntau yam roj hmab yog sib xyaw thiab molded, thiab tseem tuaj yeem ua rau cov ntaub ntawv sib khi rau cov khoom sib txuas ntawm cov roj foob pob hluav taws. Asbestos thiab phenolic resin laminates tuaj yeem siv los ua cov ntaub ntawv pov thawj cua sov rau lub taub hau cuaj luaj. Xiav asbestos kuj tseem siv tau los ua tshuaj tiv thaiv, tiv thaiv atomic hauv ob sab phlu, muab faib lossis lim, acid-resistant packing, roj hmab ntawv, thiab lwm yam.

Asbestos muaj kuab paug

Kwv yees li 95% ntawm asbestos siv nyob rau hauv lub ntiaj teb no yog chrysotile asbestos, thiab nws cov fibers yuav muab faib ua fiber ntau zoo. Rau txhua tuj ntawm asbestos noj hauv kev lag luam, kwv yees li 10 grams ntawm asbestos fiber raug tso tawm rau hauv ib puag ncig. Ib kilogram ntawm asbestos muaj txog 1 lab fiber ntau. Txoj kab uas hla ntawm cov metafiber feem ntau yog 0.5 microns, thiab qhov ntev yog tsawg dua 5 microns. Nws tuaj yeem raug tshem tawm hauv huab cua thiab dej rau lub lis piam thiab hli, ua rau muaj kuab paug tsis tu ncua. Cov kev tshawb fawb tau pom tias cov kab mob uas muaj feem cuam tshuam rau asbestos tau nthuav dav hauv ntau txoj haujlwm ua lag luam. Xws li asbestos mining, ua thiab siv cov asbestos lossis asbestos-muaj cov ntaub ntawv nyob rau hauv ntau yam lag luam (kev tsim kho, nkoj thiab tsheb kho, metallurgy, textiles, mechanical thiab hluav taws xob engineering, chemistry, kev ua liaj ua teb, thiab lwm yam).
