Traditional Brake Pads muaj asbestos
Yav dhau los, ntau lub tsheb nres tsheb muaj cov asbestos. Asbestos yog ib txwm tshwm sim fibrous ntxhia uas muaj cov cua sov zoo, ua kom tsis zoo thiab lub zog txhua yam. Vim yog cov khoom no, nws tau siv dav hauv kev tsim cov khoom siv brakes thiab tuaj yeem pab cov tsheb tiv taus kub thiab kev sib txhuam thaum lub sijhawm nres.
Asbestos txaus ntshai tau ua rau nws phasing tawm
Txawm li cas los xij, asbestos yog cov kab mob carcinogen. Thaum cov asbestos fibers tau tso tawm hauv huab cua thiab nqus tau los ntawm lub cev, lawv tuaj yeem tso rau hauv lub ntsws, thiab kev sib txuas mus ntev yuav ua rau cov kab mob loj xws li asbestosis, mob ntsws cancer thiab mesothelioma.
Nrog rau kev paub ntau ntxiv txog kev phom sij ntawm asbestos, ntau lub teb chaws thiab cheeb tsam tau pib maj mam txwv kev siv cov asbestos hauv cov khoom sib txhuam xws li tsheb nres tsheb.
Feem ntau cov tsheb nres tsheb niaj hnub no tsis muaj asbestos
Niaj hnub no, cov ntaub ntawv tseem ceeb siv hauv tsheb nres tsheb tsis muaj asbestos lawm. Hloov chaw, cov ntaub ntawv xws li semi-metallic, ceramic, thiab organic (non-asbestos organic) yog siv.
Semi-metallic nres pads muaj hlau fibers (xws li steel fibers) thiab lwm yam additives rau zoo braking kev ua tau zoo thiab tshav kub dissipation, thiab yog haum rau high-kev ua tau zoo tsheb thiab ib co tsheb hnyav. Ceramic brake pads yog tsim los ntawm ceramic fibers, fillers thiab binders, thiab lwm yam. Lawv muaj kev ruaj ntseg braking kev ua tau zoo, tsis tshua muaj suab nrov thiab tsim cov plua plav tsawg, thiab yog dav siv nyob rau hauv ntau lub tsheb zoo tib yam thiab high-end tsheb. Organic brake pads, ntawm qhov tod tes, yog tsim los ntawm ntau yam organic fibers thiab binders, thiab kuj pheej yig, nrog braking kev ua tau zoo raws li qhov xav tau ntawm lub tsheb nruab nrab.
Hauv kev xaus, txawm hais tias feem ntau cov tsheb nres tsheb niaj hnub no tsis muaj asbestos-dawb lawm, asbestos-muaj cov pawm nres tseem tuaj yeem pom nyob rau hauv qee lub tsheb qub lossis cov khoom tsis ua raws cai, yog li thaum kho thiab hloov cov paib nres, koj yuav tsum xaiv cov khoom uas muaj kev nyab xeeb. thiab ib puag ncig tus qauv.
