Asbestos Bulk Bag

Asbestos, tseem hu ua "asbestos fiber", yog lub ntsiab lus dav dav rau qee cov zaub mov silicate uas tuaj yeem faib ua elastic fiber filaments. Tshuaj formula: 3MgO·2SiO2·2H2O, fibrous, daj-ntsuab los yog dawb, dawb thaum phua rau hauv fluff, silky luster, elastic fiber, asbestos muaj acid kuj, alkali tsis kam thiab kub tsis kam, thiab yog ib tug tsis zoo conductor ntawm tshav kub thiab hluav taws xob. Cov fibers ntev dua yog siv los ua cov khoom siv hluav taws xob, xws li asbestos hlua, asbestos siv, ntaub asbestos, thiab lwm yam.; luv fibers yog siv los ua asbestos cement khoom, asbestos suab rwb thaiv tsev cov ntaub ntawv, asbestos rwb thaiv tsev cov ntaub ntawv (asbestos magnesium carbonate rwb thaiv tsev hmoov) thiab tsawg-voltage hluav taws xob cov khoom siv insulating cov ntaub ntawv, thiab lwm yam. Asbestos tsim ib tug loj npaum li cas ntawm hmoov av thiab siv nyob rau hauv cov txheej txheem. ntawm cov mining, uas yuav ua rau muaj kev puas tsuaj rau tib neeg lub cev hauv ntau txoj hauv kev, thiab kev tiv thaiv yuav tsum muaj zog.

Asbestos fibers tuaj yeem siv rau hauv xov paj, xov, hlua, ntaub, ntim, thiab lwm yam, thiab siv los ua cov ntaub ntawv lossis cov ntaub qhwv rau kev sib kis, tiv thaiv tshav kub, rwb thaiv tsev kub, thiab rwb thaiv tsev. Nyob rau hauv kev tsim kho, nws yog tsuas yog siv los ua asbestos boards thiab asbestos ntawv fireproof boards. Rwb thaiv tsev kav thiab kiln mats, thermal rwb thaiv tsev, rwb thaiv tsev kub, rwb thaiv tsev kub, suab rwb thaiv tsev thiab lwm yam ntaub ntawv. Asbestos fibers tuaj yeem sib xyaw nrog cov cement los ua cov khoom asbestos cement, xws li asbestos cement vuas, boards, ru tsev panels, asbestos kav, thiab lwm yam. Asbestos thiab asphalt tuaj yeem sib xyaw ua cov khoom asbestos asphalt, xws li asbestos asphalt boards, ntaub (linoleum ), ntawv, cib, asbestos kua coatings, cement txoj kev thiab putty rau expansion tawg, thiab lwm yam., siv rau waterproofing, cov ntaub ntawv rau tshav kub preservation, rwb thaiv tsev, Acid thiab alkali tsis kam, tsheb engineering cov ntaub ntawv. Nyob rau hauv cov nqe lus ntawm kev tiv thaiv lub teb chaws, asbestos yog bonded nrog yas xws li phenolic thiab polypropylene, thiab yuav ua tau rau hauv rockets, aircraft tis, roj tso tsheb hlau luam, foob pob ua ntxaij tail nozzles thiab high-speed torpedo launchers, ships, tsheb, aircraft, tso tsheb hlau luam, thiab ships. . Lub suab rwb thaiv tsev thiab cov ntaub ntawv rwb thaiv tsev kub yog tov nrog asbestos thiab ntau yam roj hmab, thiab tseem tuaj yeem ua rau cov ntaub ntawv sib khi rau cov pob qij txha ntawm cov kua foob pob hluav taws. Asbestos thiab phenolic resin laminates yog siv los ua cov ntaub ntawv kub-resistant rau lub taub hau missile. Blue asbestos kuj tseem siv tau los ua tshuaj tiv thaiv, tshuaj tiv thaiv atom hauv ob sab phlu, cais lossis lim, kua qaub-resistant muab tub lim, ntawv roj hmab, thiab lwm yam.

Kwv yees li 95 feem pua ​​​​ntawm cov asbestos siv hauv ntiaj teb yog chrysotile, nws cov fibers tuaj yeem tawg mus rau hauv cov fibers zoo heev. Rau txhua tuj ntawm asbestos noj hauv kev lag luam, kwv yees li 10 grams asbestos fibers raug tso tawm rau hauv ib puag ncig. Ib kilogram ntawm asbestos muaj txog ib lab fibers. Microfibers feem ntau yog 0.5 microns nyob rau hauv txoj kab uas hla thiab tsawg dua 5 microns nyob rau hauv ntev. Nws tuaj yeem dai hauv huab cua thiab dej rau lub lis piam thiab hli, ua rau muaj kuab paug tsis tu ncua. Kev tshawb fawb qhia tau hais tias kev mob asbestos muaj feem ntau 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, electromechanical engineering, chemistry, kev ua liaj ua teb, thiab lwm yam).
