Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm asbestos molded brake hauv ob sab phlu?
Qhov zoo ntawm Asbestos Moulded Brake Lineing Rolls
Zoo heev kub tsis kamAsbestos fibers muaj qhov siab melting point thiab muaj zog thermal stability. Lawv tuaj yeem tswj hwm kev ncaj ncees txawm tias nyob rau hauv qhov kub thiab txias uas tsim los ntawm qhov ntev - lub sij hawm lossis hnyav - lub luag haujlwm nres (feem ntau ncav cuag ntau pua degrees Celsius). Qhov no tiv thaiv lub brake hauv ob sab phlu los ntawm deforming, charring, los yog poob kev sib txhuam vim overheating.
Zoo kev sib txhuam stabilityKev sib txhuam coefficient ntawm asbestos-raws li cov hlua nres yog qhov ruaj khov nyob rau ntau qhov kub, qhov nrawm, thiab lub zog siab. Qhov no ua kom lub zog sib npaug, tsis txhob muaj teeb meem xws li nres nres (kev sib txhuam hauv kev sib txhuam thaum kub dhau) lossis nres nres (dhau, kev sib txhuam ntau dhau), uas yog qhov tseem ceeb rau kev nyab xeeb ntawm cov tshuab hnyav thiab tsheb.
Zoo hnav tsis kamAsbestos fibers muaj lub zog txhua yam thiab tsis yooj yim hnav. Thaum ua ke nrog cov binders thiab fillers nyob rau hauv lub brake hauv ob sab phlu qauv, lawv muaj peev xwm ua tau kom ntev lub neej kev pab cuam ntawm lub brake tivthaiv, txo qhov zaus ntawm kev hloov- ib qho zoo nkauj feature rau hnyav- cov khoom siv ua haujlwm hnyav.
Tsawg tus nqi tsim khoomAsbestos yog ib qho khoom siv dav dav thiab pheej yig. Cov txheej txheem tsim khoom ntawm asbestos molded brake hauv ob sab phlu yog qhov yooj yim, uas ua rau tag nrho cov nqi tsim khoom qis, ua rau tus nqi -kev xaiv zoo rau cov ntawv loj - teev kev lag luam yav dhau los.
Disadvantages ntawm Asbestos Moulded Brake Lineing Rolls
Muaj mob hnyavQhov no yog qhov teeb meem tseem ceeb tshaj plaws thiab tuag taus. Asbestos fibers yog me me thiab lub teeb yuag. Thaum lub sijhawm tsim khoom, kev teeb tsa, siv, thiab kev saib xyuas ntawm cov hlua khi, cov fibers no tuaj yeem yooj yim ua pa thiab nqus tau los ntawm tib neeg. Ntev -lub sij hawm raug rau asbestos fibers tuaj yeem ua rau muaj kab mob loj xws liasbestosis(scarring ntawm lub ntsws cov ntaub so ntswg),mesothelioma(ib qho mob qog nqaij hlav tsawg thiab mob hnyav ntawm lub ntsws lossis lub plab), thiab mob ntsws cancer. Cov kab mob no feem ntau muaj lub sijhawm latency ntev (feem ntau xyoo caum) thiab nyuaj kho.
Ib puag ncig muaj kuab paugMuab pov tseg asbestos brake hauv ob sab phlu, nrog rau cov plua plav tsim thaum lub sij hawm nres, tuaj yeem ua rau cov av thiab dej. Asbestos fibers nyob rau hauv ib puag ncig tuaj yeem nyob mus ntev thiab tseem ua rau muaj kev pheej hmoo rau ecological systems thiab tib neeg kev noj qab haus huv. Txoj kev pov tseg tsis raug (xws li kev muab pov tseg lossis kev tua hluav taws) yuav kis tau cov pa phem ntxiv.
Kev txwv los ntawm cov kev cai thoob ntiaj tebVim muaj kev pheej hmoo rau kev noj qab haus huv loj, feem ntau lub tebchaws thiab cheeb tsam tau tshaj tawm txoj cai nruj thiab cov kev cai txwv tsis pub lossis txwv kev tsim khoom, muag, thiab siv cov asbestos- muaj cov khoom, suav nrog asbestos nres hauv ob sab phlu. Kev siv cov khoom zoo li no yuav tsis tsuas yog raug nplua raws li txoj cai tab sis kuj ua rau lub tuam txhab cov duab thiab lub koob npe nrov ntawm kev lag luam.
Tsis zoo sib xws nrog qee qhov tshiab braking systemsNrog rau kev txhim kho tsheb thiab tshuab siv tshuab, ntau lub tshuab nres tsheb niaj hnub xav tau sib dua, nyiam ib puag ncig, thiab siab dua - cov khoom siv nres. Asbestos nres hauv ob sab phlu yog hnyav heev thiab tsis ua tau raws li cov qauv tsim ntawm cov khoom siv tshiab. Tsis tas li ntawd, lawv qhov kev sib txhuam tsis tuaj yeem ua tau raws li qhov xav tau ntawm qee qhov siab -precision braking systems.
Koj xav kom kuv pab koj txheeb covkev sib piv cov lusnruab nrab ntawm asbestos nres hauv ob sab phlu thiab lawv cov kev xaiv tseem ceeb (ceramic, semi{0}}metallic)?
