Txhawm rau ua kom cov khoom zoo siab, muaj ob qhov tseem ceeb: sab nraub qaum thiab cov khoom siv raw.Txij li cov khoom siv raw (kev sib txhuam thaiv) yog qhov ncaj qha kov nrog nres disc, nws yog hom thiab zoo plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm nres.Qhov tseeb, muaj ntau pua hom khoom siv raw hauv kev ua lag luam, thiab peb tsis tuaj yeem qhia cov khoom siv raw khoom raws li cov khoom siv nres.Yog li yuav ua li cas peb xaiv cov khoom tsim nyog rau kev tsim khoom?Cia peb pib paub qhov kev faib tawm ntxhib ntawm cov khoom siv raw:
Raw khoom pob
Cov khoom siv raw tuaj yeem muab faib ua 4 hom:
1.Asbestos hom:Cov khoom siv thaum ntxov tshaj plaws siv rau ntawm cov khoom siv nres ua lub luag haujlwm hauv kev txhim kho lub zog.Vim nws tus nqi qis thiab qee qhov kub-kub kuj, nws yog dav siv.Txawm li cas los xij, cov khoom siv asbestos tau raug pov thawj tias yog Carcinogen los ntawm cov neeg kho mob thiab tam sim no txwv tsis pub nyob hauv ntau lub tebchaws.Feem ntau cov khw muag khoom tsis tso cai rau kev muag khoom ntawm cov ntaub thaiv npog uas muaj cov asbestos, yog li nws yog qhov zoo tshaj kom tsis txhob muaj qhov no thaum yuav cov khoom siv raw.
2.Semi-metallic hom:Los ntawm cov tsos, nws muaj fibers zoo thiab hais, uas tuaj yeem yooj yim txawv ntawm asbestos thiab NAO hom.Piv nrog rau cov khoom siv tsoos tsoos, nws tsuas yog siv cov ntaub ntawv hlau los ua kom lub zog ntawm cov khoom siv nres.Nyob rau tib lub sij hawm, qhov kub thiab txias tsis kam thiab tshav kub dissipation muaj peev xwm kuj superior rau ib txwm cov ntaub ntawv.Txawm li cas los xij, vim muaj cov ntsiab lus hlau siab ntawm cov khoom siv nres nres, tshwj xeeb tshaj yog nyob rau hauv qhov chaw qis qis, nws tuaj yeem ua rau lub ntsej muag hnav thiab lub suab nrov ntawm lub nres nres thiab nres nres vim yog lub zog nres ntau dhau.
3. Low-metallic hom:Los ntawm cov tsos, cov hlau tsis tshua muaj hlau nres yog me ntsis zoo ib yam li cov khoom siv hluav taws xob semimetallic, nrog cov fibers zoo thiab cov khoom.Qhov txawv yog tias hom no muaj cov ntsiab lus ntawm cov hlau qis dua li cov hlau semi, uas daws cov teeb meem ntawm cov nres disc hnav thiab txo cov suab nrov.Txawm li cas los xij, lub neej ntev ntawm cov pawm nres yog me ntsis qis dua li ntawm cov khoom siv hluav taws xob semimetallic.
4.Ceramic hom:Cov khoom nres ntawm cov mis no siv cov khoom siv tej hub uas tsis tshua muaj plua plav, tsis muaj plua plav, tsis muaj xeb ntawm lub log tsheb, lub neej ntev, thiab ib puag ncig kev tiv thaiv.Tam sim no, nws tau nthuav dav hauv kev lag luam ntawm North America, Europe, thiab Nyiv.Nws cov cua sov poob zoo dua li ntawm cov khoom siv roj hmab semi hlau, thiab qhov tseem ceeb tshaj plaws yog tias nws txhim kho qhov kev pabcuam nruab nrab ntawm lub tshuab nres nres thiab tsis muaj kuab paug.Hom nres nres no muaj kev sib tw ua lag luam muaj zog nyob rau xyoo tas los no, tab sis tus nqi kuj tseem siab dua lwm cov ntaub ntawv.
Yuav ua li cas xaiv cov khoom siv raw?
Txhua hom khoom siv raw muaj ntau yam khoom sib txawv, xws li resin, txhuam hmoov, steel fiber, aramid fiber, vermiculite thiab lwm yam.Cov ntaub ntawv no yuav muab sib xyaw ua ke kom ruaj khov thiab tau txais cov khoom siv kawg uas peb xav tau.Peb twb tau qhia txog plaub yam khoom sib txawv hauv cov ntawv nyeem dhau los, tab sis cov khoom siv raw yuav tsum xaiv hauv kev tsim khoom?Qhov tseeb, cov neeg tsim khoom yuav tsum muaj kev nkag siab zoo ntawm kev ua lag luam uas lawv xav muag ua ntej ntau lawm.Peb yuav tsum paub tias cov khoom siv raw khoom twg yog qhov nrov tshaj plaws nyob rau hauv kev lag luam hauv zos, dab tsi yog txoj kev hauv zos, thiab seb lawv puas tsom mus rau kev kub ntxhov lossis teeb meem suab nrov.Tag nrho cov xwm txheej no yuav tsum tau xav txog.
Ib feem ntawm cov khoom siv raw
Raws li cov neeg tsim khoom paub tab, lawv yuav txuas ntxiv tsim cov qauv tshiab, ntxiv cov ntaub ntawv tshiab hauv cov qauv los yog hloov feem ntawm txhua yam khoom los ua kom cov pawm nres tau zoo dua.Niaj hnub no, kev ua lag luam kuj zoo li cov khoom siv carbon-ceramic uas muaj kev ua tau zoo dua li hom ceramic.Cov neeg tsim khoom yuav tsum xaiv cov khoom siv raw raws li qhov xav tau tiag tiag.
