Asbestos yog cov khoom siv hauv tsev tshwj xeeb uas tsis muaj qhov sib piv hauv nws cov khoom. Nws qhov kub tsis kam yog siab heev - mus txog 500 degrees. Hauv kev tsim kho, feem ntau siv asbestos dawb.
Scope of application
Cov khoom siv yog siv los ua kom muaj zog ntawm cov cement, hauv kev tsim cov ntawv kub-resistant thiab ruaj khov thiab cov kav dej, pebbles. Asbestos tau siv dav hauv kev tsim cov ntsiab lus txhawm rau txhawm rau txhim kho lawv cov hnav tsis kam. Nws yog nquag siv nyob rau hauv brakes raws li ib tug anti-kev sib txhuam, thiab nyob rau hauv zus tau tej cov asph alt. Kev siv cov asbestos yog nrov hauv kev lag luam raws li cov khoom pom. Nws yog ib tug muab tub lim nyob rau hauv yas, scraps thiab insulators.
khoom lag luam asbestos
Asbestos cov khoom lag luam muaj cov hluav taws xob zoo heev, rwb thaiv tsev kub thiab cov yam ntxwv refractory. Ua ntej ntawm tag nrho cov, lawv yog siv nyob rau hauv kev lag luam rau tsim hermetic kev twb kev txuas thiab raws li kev tiv thaiv hluav taws. Cov yam ntxwv tshwj xeeb yog siab heev uas lawv tau pom zoo rau kev siv cov insulator hauv cov chav flammable. Nws yuav tsum tau muab sau tseg tias asbestos thiab nws cov derivativesmuaj qhov loj.
Hauv kev lag luam metallurgical, cov khoom lag luam asbestos yog siv los tsim cov kav dej thiab cov kav dej. ATI yog siv los ua cov rwb thaiv tsev thermal thiab cov khoom siv hauv ob sab phlu rau cov khaub ncaws tshwj xeeb thiab ntau lwm yam khoom siv rau kev lag luam.
Asbestos non-woven npuag kuj siv los ua thermal rwb thaiv tsev. Nws yog siv feem ntau rau insulating qhov chaw kub, nws tuaj yeem tiv taus kub txog 400 degrees Celsius. Elastic asbestos ntawv yog siv los insulate chav thiab kav dej thiab lwm qhov chaw kub. Nws tseem yog tsim los ntawm asbestos.
Asbestos npuag: daim ntawv thov thiab hom
Ntxiv rau cov ntaub tsis-woven, tseem muaj cov ntaub qhwv los ntawm asbestos yarn nrog viscose, iav fiber lossis paj rwb xov. Cov ntaub zoo li no hu ua asbotkan (asbestos npuag) (GOST 6102-94). Ntxiv dua thiab, lub ntsiab yam ntxwv yog thermal rwb thaiv tsev. Cov ntaub no yog siv los ua txhua yam rau cov neeg ua haujlwm koom nrog hauv kev tsim khoom hauv kev cob qhia uas muaj qhov kub thiab txias thiab tua hluav taws.
Asbestos ntaub (asbestos ntaub) yog dav siv los insulate furnaces thiab lwm yam khoom siv cua sov. Cov ntaub zoo li no muaj txiaj ntsig zoo hauv kev tua hluav taws me me thiab cov khoom siv uas tsis tuaj yeem hlawv hauv qhov chaw tsis muaj cua.
Asbestos ntaub: yam ntxwv
Nws zoo li cov ntaub ntom ntom. Nws tsis lom. Qhov zoo no tseem ceeb heev.thaum sewing overalls. Lub txee lub neej ntawm xws li canvas, tsis poob ntawm tag nrho cov zoo, yog los ntawm 5 mus rau 10 xyoo.
Nws yuav tsum tau muab sau tseg tias asbestos ntaub yog siv tsis tau tsuas yog nyob rau hauv tailoring zuag qhia tag nrho, tab sis kuj nyob rau hauv zus tau tej cov ntaub ntawv rubberized thiab asbestos textolite.
Muaj cov khoom tshwj xeeb ntawm asbot fabrics uas yog tsim los siv hauv aviation.
Txawm hais tias cov ntaub asbot tsis muaj tshuaj lom, tseem yuav tsum tau ceev faj thaum ua haujlwm nrog lawv. Qhov tseeb yog tias thaum siv, lawv tuaj yeem tso cov hmoov av asbestos mus rau ib puag ncig. Nws, nyob rau hauv lem, muaj ib tug fibrogenic nyhuv, yuav tsub kom nyob rau hauv lub ntsws. Yog li ntawd, kev cob qhia ua haujlwm nrog cov ntaub asbestos yuav tsum tau nruab nrog lub qhov cua zoo, thiab txhua tus neeg ua haujlwm yuav tsum siv cov cuab yeej tiv thaiv tus kheej.
Tam sim no, asbestos npuag tau tsim ntau ntau thiab ntau hom, qib nrog cov khoom sib txawv thiab siv ntau yam.
Khoom ntawm asbestos fabrics
Fabrics ua los ntawm asbestos threads muaj qhov zoo hauv qab no.
Ua ntej, lawv muaj zog heev. Qhov thib ob, lawv yog cov kav ntev. Thib peb, lawv yog cov ruaj khov. Plaub, lawv muaj peev xwm tiv taus cua sov thiab hluav taws. Thiab thib tsib, lawv khaws lawv cov khoom ntawm qhov kub thiab txias.
Environmental yam ntxwv ntawm asbestos fabrics
Asbestos npuag muaj kev lees paub zoo thiab ua tau raws li kev cai hauv tebchaws.
Asbot fibers muaj peev xwmyooj yim faib ua me me. Lub cev yog cuam tshuam ncaj qha los ntawm asbestos plua plav, uas nkag mus rau nws los ntawm kev nqus pa. Nws tuaj yeem ua rau ntau yam kab mob, xws li mob ntsws cancer lossis mob qog nqaij hlav ntawm lub plab kab noj hniav thiab pleura. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum tau ceev faj thaum ua hauj lwm nrog fabrics, txij li thaum tsis muaj kev ruaj ntseg hloov rau asbestos. Tsuas yog cov khoom no muaj cov yam ntxwv zoo li no. Tab sis nws cov nqi kim dua tseem poob qis ntawm lawv cov yam ntxwv rau nws cov khoom siv kho tshuab.
Txhawm rau txo qhov kev pheej hmoo ntawm kev nqus cov plua plav asbestos, cov khoom tsim los ntawm cov khoom siv no tuaj yeem pleev xim los yog npog nrog zaj duab xis, thiab cov khoom uas tsis kho nrog cov khoom tiv thaiv yuav tsum tsis txhob muab tso rau hauv qhov chaw uas muaj huab cua zoo.
