Yuav ua kom cov ntaub nres zoo, muaj ob qhov tseem ceeb: lub phaj tom qab thiab cov khoom siv raw. Vim tias cov khoom siv raw (kev sib txhuam thaiv) yog qhov kov ncaj qha nrog lub disc nres, nws hom thiab qhov zoo ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm lub nres. Qhov tseeb, muaj ntau pua hom khoom siv raw hauv kev ua lag luam, thiab peb tsis tuaj yeem qhia hom khoom siv raw raws li qhov tsos ntawm cov ntaub nres. Yog li peb yuav xaiv cov khoom siv raw li cas rau kev tsim khoom? Cia peb xub paub qhov kev faib tawm ntawm cov khoom siv raw:
Cov khoom siv raw pob
Cov khoom siv raw tuaj yeem muab faib ua 4 hom:
1. Hom Asbestos:Cov khoom siv raw thaum ub uas siv rau ntawm cov ntaub nres tau ua lub luag haujlwm hauv kev txhim kho lub zog. Vim nws tus nqi qis thiab qee qhov kev tiv taus kub siab, nws tau siv dav. Txawm li cas los xij, cov khoom siv asbestos tau ua pov thawj tias yog Carcinogen los ntawm lub zej zog kho mob thiab tam sim no raug txwv hauv ntau lub tebchaws. Feem ntau cov khw tsis pub muag cov ntaub nres uas muaj asbestos, yog li nws yog qhov zoo tshaj plaws kom tsis txhob muaj qhov no thaum yuav cov khoom siv raw.
2. Hom hlau ib nrab:Los ntawm qhov tsos, nws muaj cov fibers zoo thiab cov khoom me me, uas tuaj yeem paub qhov txawv ntawm asbestos thiab NAO hom. Piv nrog cov ntaub ntawv nres ib txwm muaj, nws feem ntau siv cov ntaub ntawv hlau los ua kom lub zog ntawm cov ntaub nres. Tib lub sijhawm, qhov kub siab thiab lub peev xwm tso cua sov kuj zoo dua li cov ntaub ntawv ib txwm muaj. Txawm li cas los xij, vim muaj cov hlau ntau ntawm cov ntaub ntawv nres, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kub qis, nws tuaj yeem ua rau qhov chaw hnav thiab suab nrov ntawm lub disc nres thiab ntaub nres vim muaj kev siab nres ntau dhau.
3. Hom hlau tsawg:Los ntawm qhov tsos, cov nres nres uas muaj cov hlau tsawg zoo ib yam li cov nres nres semi-metallic, nrog cov fibers me me thiab cov khoom me me. Qhov txawv yog tias hom no muaj cov hlau tsawg dua li cov hlau semi, uas daws qhov teeb meem ntawm kev hnav lub disc nres thiab txo cov suab nrov. Txawm li cas los xij, lub neej ntawm cov nres nres qis dua me ntsis dua li cov nres nres semi-metallic.
4. Hom khoom siv ua los ntawm av nplaum:Cov ntaub nres ntawm cov mis no siv cov khoom siv ceramic tshiab uas tsis muaj qhov ntom ntom, tiv taus kub siab, thiab tiv taus hnav, uas muaj qhov zoo ntawm tsis muaj suab nrov, tsis muaj hmoov av poob, tsis muaj xeb ntawm lub log hub, lub neej ntev, thiab kev tiv thaiv ib puag ncig. Tam sim no, nws muaj ntau hauv kev lag luam ntawm North America, Tebchaws Europe, thiab Nyiv. Nws qhov kev poob qis kub zoo dua li cov ntaub nres semi metallic, thiab qhov tseem ceeb yog tias nws txhim kho lub neej nruab nrab ntawm cov ntaub nres thiab tsis muaj kuab paug. Hom ntaub nres no muaj kev sib tw ua lag luam muaj zog hauv xyoo tas los no, tab sis tus nqi kuj yuav 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 cov resin, hmoov txhuam, hlau fiber, aramid fiber, vermiculite thiab lwm yam. Cov ntaub ntawv no yuav raug sib xyaw ua ke thiab tau txais cov khoom siv raw kawg uas peb xav tau. Peb twb tau qhia plaub yam khoom siv raw sib txawv hauv cov ntawv dhau los, tab sis cov chaw tsim khoom yuav tsum xaiv cov khoom siv raw twg hauv kev tsim khoom? Qhov tseeb, cov chaw tsim khoom yuav tsum nkag siab zoo txog kev ua lag luam uas lawv xav muag ua ntej tsim khoom loj. Peb yuav tsum paub tias cov khoom siv raw twg nrov tshaj plaws hauv kev ua lag luam hauv zos, cov xwm txheej ntawm txoj kev hauv zos yog dab tsi, thiab seb lawv puas tsom mus rau kev tiv taus cua sov lossis teeb meem suab nrov. Tag nrho cov yam no yuav tsum xav txog.
Ib feem ntawm cov khoom siv raw
Rau cov tuam txhab tsim khoom laus, lawv yuav tsim cov mis tshiab tas li, ntxiv cov khoom siv tshiab hauv cov mis lossis hloov pauv qhov sib piv ntawm txhua yam khoom siv kom ua rau cov ntaub nres ua haujlwm tau zoo dua. Niaj hnub no, kev ua lag luam kuj tshwm sim cov khoom siv carbon-ceramic uas muaj kev ua tau zoo dua li hom ceramic. Cov tuam txhab tsim khoom yuav tsum xaiv cov khoom siv raw raws li qhov xav tau tiag tiag.
