Asbestos-dawb nruas nres hauv ob sab phlu tau dhau los ua tus qauv hauv kev lag luam tsheb tau ntau xyoo lawm, uas tau tsav los ntawm kev noj qab haus huv thiab kev nyab xeeb. Txawm li cas los xij, zoo li txhua yam thev naus laus zis, lawv tuaj nrog lawv tus kheej qhov zoo thiab qhov tsis zoo piv rau cov qub asbestos-raws li hauv ob sab phlu.
Ntawm no yog cov ncauj lus kom ntxaws.
Qhov zoo ntawm Asbestos-Dawb Nres Nres
1. Tsis yog -Toxic and Safe for Health:
Qhov Zoo Tshaj Plaws Tseem Ceeb: Asbestos fibers, thaum nqus tau, yog cov carcinogen paub thiab tuaj yeem ua rau cov kab mob xws li mesothelioma, asbestosis, thiab mob ntsws cancer. Asbestos- cov ntaub qhwv dawb tshem tawm qhov kev pheej hmoo ntawm kev noj qab haus huv hnyav rau cov kws kho tsheb thaum lub sijhawm teeb tsa thiab kho, thiab rau cov pej xeem los ntawm cov pa paug plua plav.
2. Superior High -Kev Ua Haujlwm Kub:
Asbestos linings raug kev txom nyem los ntawm "faj" ntawm qhov kub thiab txias, qhov twg lawv cov kev sib txhuam coefficient poob qis heev. Niaj hnub nimno non-asbestos organic (NAO) thiab semi- cov ntaub ntawv hlau yog tsim los tiv thaiv qhov kub thiab txias nrog kev ua tau zoo dua qub, muab kev ruaj ntseg dua thaum siv dua lossis hnyav dua.
3. Kev ua tau zoo dua hauv cov dej ntub dej:
Asbestos absorbs noo noo, uas tuaj yeem ua rau poob ntawm lub zog braking thiab nce corrosion hauv cov dej ntub lossis ntub dej. Feem ntau cov asbestos- cov ntaub ntawv dawb yog tsawg dua hygroscopic (dej-absorbing), ua rau muaj kev ua tau zoo dua qub hauv huab cua los nag.
4. Softer ntawm Nres Nres:
Feem ntau, tsis yog -asbestos hauv ob sab phlu (tshwj xeeb tshaj yog NAO) tsawg dua abrasive dua semi-nws yog xim hlau lossis asbestos linings. Qhov no ua rau txo qis hnav thiab tsim kua muag ntawm lub nruas nres lawv tus kheej, txuas ntxiv lawv lub neej kev pabcuam.
5. Kev ua haujlwm ntsiag to:
Txawm hais tias tsis muaj tseeb thoob ntiaj teb, ntau NAO cov qauv tsim los ua kom ntsiag to thiab ua kom tsis muaj zog dua li lawv cov qub qub, tshwj xeeb tshaj yog thaum lawv txias.
6. Ua raws li cov kev cai:
Kev tsim, muag, thiab siv cov asbestos hauv cov khoom lag luam nres yog txwv lossis txwv hnyav hauv ntau lub tebchaws. Kev siv asbestos- cov ntaub ntawv dawb yog qhov yuav tsum tau ua raws li txoj cai.
Disadvantages of Asbestos-Dawb Nres Nres
1. Tus nqi siab dua:
Cov txheej txheem tsim khoom thiab cov khoom siv siab heev (xws li aramid fibers, ceramic compounds, thiab sintered metals) siv nyob rau hauv siab - zoo asbestos - cov ntaub ntawv dawb feem ntau ua rau lawv kim dua los tsim dua li qub asbestos - cov khoom siv tau.
2. Plua plav tiam:
Thaum cov plua plav tsis yog - lom, qee cov qauv (tshwj xeeb yog ib nrab-nws yog xim hlau) tuaj yeem tsim cov hmoov av tsaus nti, nws yog xim hlau uas pom zoo heev thiab tuaj yeem nyuaj los ntxuav ntawm cov log hlau. Qhov no yog feem ntau pom raws li ib tug cosmetic drawback.
3. Variability nyob rau hauv Zoo thiab kev ua tau zoo:
Lo lus "asbestos-dawb" suav nrog ntau yam khoom siv nrog ntau yam kev ua tau zoo sib txawv. Qhov pheej yig, qis-NAO hauv ob sab phlu zoo yuav tsis muaj zog nres thiab hnav sai heev, qhov zoo tshaj plaws ceramic lossis semi-cov ntaub ntawv hlau yuav ua tau zoo heev. Qhov no ua rau kev xaiv cov khoom tsim nyog tseem ceeb.
4. Hla-Lub Sij Hawm (Nyob hauv-In):
Ntau cov asbestos niaj hnub no- cov ntaub ntawv pub dawb yuav tsum muaj cov txheej txheem "pob txaj-" kom hloov tau ib txheej ntawm cov khoom sib txhuam mus rau lub nruas. Yog tsis muaj qhov no, lawv yuav tsis ua tiav lawv lub peev xwm braking tag nrho thiab tuaj yeem ua rau lub suab nrov lossis kev co.
5. Kev ua haujlwm txias tuaj yeem sib txawv:
Qee cov formulations, tshwj xeeb tshaj yog tej yam semi-metallic linings, tej zaum yuav muaj ib tug me ntsis kev sib txhuam coefficient thaum lawv txias heev piv rau lawv qhov zoo tshaj plaws kev khiav hauj lwm kub. Txawm li cas los xij, lawv feem ntau sov so tom qab thawj ob peb daim ntawv thov nres.
Hom Hom Asbestos -Dawb Linings & Lawv Kev Lag Luam - tawm
Nws yog ib qho pab tau kom nkag siab txog cov hom:
1.Non-Asbestos Organic (NAO):
- Pros:Nyob ntsiag to, du pedal xav, maj mam ntawm nruas.
- Cons:tuaj yeem hnav sai dua thiab tsim cov plua plav (tsis yog- lom) ntau dua li lwm hom. Tsis zoo rau kev siv siab - kev ntxhov siab.
2.Semi-Nws yog xim hlau:
- Pros:Zoo heev tshav kub dissipation, muaj zog nres lub zog, ruaj.
- Cons:Nws tuaj yeem ua suab nrov, ntau dua abrasive rau nruas, thiab tsim cov plua plav hlau dub. Tej zaum yuav ua tau tsis zoo thaum txias heev.
3.Low-Metallic NAO:
Kev sib xyaw ntawm NAO nrog me me ntawm cov hlau fibers. Muab qhov sib npaug zoo ntawm kev ua haujlwm, suab nrov, thiab hnav, tab sis tseem tuaj yeem ua plua plav.
4.Ceramic:
- Pros:Nyob ntsiag to heev, tsim lub teeb me me- xim plua plav uas tsis lo rau lub log, kev ua haujlwm ruaj khov nyob thoob plaws qhov kub thiab txias.
- Cons:Feem ntau qhov kev xaiv kim tshaj plaws. Nws tuaj yeem ua haujlwm tsawg dua ntawm qhov kub thiab txias.
Xaus
Covqhov zoo ntawm asbestos-dawb nruas nres hauv ob sab phlu overweigh qhov tsis zoo, nrog rau kev tshem tawm ntawm kev pheej hmoo tuag taus yog ib qho tseem ceeb tshaj plaws. Cov kev tsis zoo niaj hnub no feem ntau cuam tshuam txog tus nqi, cov plua plav kom zoo nkauj, thiab qhov yuav tsum tau xaiv cov khoom zoo uas haum rau lub tsheb daim ntawv thov.
Rau feem coob ntawm cov tsav tsheb, lub siab - zoo asbestos- cov ntaub ntawv dawb (txawm yog NAO, semi-hlau, lossis ceramic) yuav muab kev nyab xeeb dua, zoo ib yam, thiab txhim khu kev qha braking kev ua tau zoo dua li cov thev naus laus zis thiab txaus ntshai asbestos nws hloov.
