Asbestos Fiber ntau

Asbestos Fiber yog dab tsi?

Asbestosfiber ntauyog serpentinite thiab hornblende series inorganic ntxhia fiber. Nws yog tsim los ntawm hydrated magnesium silicate (3MgO·3SiO₂· 2 H₂O).

Cov khoom ntawm Asbestos Fiber

Asbestos fiber ntau yog kub resistant, tsis-ignitable, dej resistant, acid resistant thiab tshuaj resistant. Muaj ntau tshaj 30 hom asbestos fiber ntau. Tab sis muaj 3 hom uas feem ntau siv hauv kev lag luam, xws li chrysotile asbestos, chrysotile asbestos thiab hlau asbestos. Asbestos yog carcinogenic. Muaj kev pheej hmoo ntawm mob qog noj ntshav mesothelioma thiab mob ntsws cancer hauv ib puag ncig nrog cov plua plav asbestos hnyav. Yog li ntawd, thaum ua haujlwm nrog asbestos, kev tiv thaiv yuav tsum tau ua.

(1) Qhov tshwj xeeb ceev thiab hnyav hnyav yog me dua. Qhov nruab nrab qhov ceev yog 2.75 thiab qhov hnyav ntawm chav tsev yog 1600 ~ 2200 kg / m³. Nws yog ib qho zoo heev lub teeb yuag khoom.

(2) Cov thermal conductivity tsawg. Lub tshav kub conductivity coefficient yog 0.198 ~ 0.244W (m·K).

(3) Cov hluav taws xob conductivity tsawg. Nws lub neej ntev dua li cov yeeb nkab hlau cam khwb cia. Nws muaj lub zog mechanical siab thiab tuaj yeem tiv taus siab heev. Nws yog cov khoom siv hluav taws xob zoo insulating.

(4) Nws yog ib qho yooj yim los txiav thiab txheej txheem. Nws tuaj yeem raug chiseled los ntawm cov ntsia hlau, uas zoo ib yam li ntoo.

(5) Nws muaj cov khoom siv tshuaj ruaj khov. Txawm hais tias nws tsis tuaj yeem tiv taus acid, nws kav ntev dua hauv cov dej ntxhia ntau dua li cov kav dej ua vaj tse
