Automotive technology yog tsim, cov khoom ntawm kev sib txhuam cov ntaub ntawv kuj hloov zuj zus nyob rau hauv txhua txoj kev, feem ntau muab faib ua ob peb pawg loj:
Organic brake ncoo
Ua ntej xyoo 1970, lub nres nres muaj ntau cov ntaub ntawv asbestos, siv cov khoom kub kub, tiv thaiv hluav taws, thiab cov yam ntxwv sib txhuam, tab sis vim tias cov hmoov ua los ntawm asbestos hauv kev tsim thiab siv, muaj ntau yam kev puas tsuaj rau tib neeg lub cev. , uas yog ib qho yooj yim ua rau cov kab mob ua pa.Cov kab mob tseem yog carcinogenic, yog li cov paj rwb nres tam sim no txwv thoob ntiaj teb.
Tom qab ntawd, tam sim no cov organic nres pads feem ntau hu ua NAO nres pads (Non-Asbestos Organic, tsis muaj pob zeb-dawb organic nres pads), uas feem ntau muaj 10% -30% ntawm cov ntaub ntawv hlau, thiab tseem suav nrog cov nroj tsuag fibers, iav Fibers, carbon, roj hmab, iav thiab lwm yam ntaub ntawv.
Organic brake pads tau txhim kho kev ua tau zoo hauv kev hnav thiab kev tswj lub suab nrov los ntawm ntau xyoo ntawm kev txhim kho thiab cov khoom siv txhim kho, tab sis kuj tsim nyog rau kev tsav tsheb txhua hnub.Cov plua plav generated thiab kev puas tsuaj rau lub nres disc yog tsawg.Txawm li cas los xij, vim yog cov khoom siv, thiab lwm yam., cov khoom siv hluav taws xob feem ntau yog kim, thiab lub Hoobkas qub feem ntau yuav siv rau cov qauv nruab nrab thiab high-end.
Semi-hlau brake ncoo
Lub npe hu ua ib nrab hlau yog feem ntau nyob rau hauv cov khoom sib txhuam siv hauv cov khoom siv nres, los ntawm li 30% -65% ntawm cov hlau - suav nrog tooj liab, hlau, thiab lwm yam. Cov yam ntxwv ntawm lub ncoo nres no yog qhov txias, kub tsis kam, tus nqi qis, thiab qhov tsis zoo yog vim cov khoom siv vim li cas, lub suab nrov thaum lub sijhawm nres yuav loj, thiab hnav cov khoom siv hlau rau lub nres nres yuav loj.Txij li thaum semi-hlau nres ncoo muaj cov yam ntxwv ntawm peb saum toj no, feem ntau yog ob daim ntawv thov loj, ib qho yog thawj lub Hoobkas txhawb nqa nres nres ntawm cov qauv nruab nrab thiab qis kawg - qhov xwm txheej no yog tus nqi qis.Lwm qhov kev taw qhia yog feem ntau nyob rau hauv kev hloov kho ntawm daim tawv nqaij - vim hais tias cov hlau brakes zoo, nws yog tsim nyog rau kev ua tau zoo ntawm lub tsheb los yog nyob rau hauv ntau yam xwm txheej.Tom qab tag nrho, nyob rau hauv txoj kev siv no, qhov siab tshaj plaws ntawm cov tawv nqaij nres yuav ncav cuag ntau tshaj 800 degrees Celsius.Yog li peb tuaj yeem pom tias ntau lub npe hloov kho muaj cov khoom siv hlau ntau dua rau kev nres ntawm kev tsav tsheb hnyav thiab cov xwm txheej.
Ceramic brake ncoo
Ceramic brake pads tuaj yeem piav qhia tias tsis txaus rau cov khoom siv hluav taws xob thiab ib nrab hlau nres.Nws cov khoom yog ua ke los ntawm ntau yam ntaub ntawv xws li ntxhia fibers, aramid fibers, thiab ceramics fibers.Ntawm ib sab, thaum tsis muaj cov khoom siv hlau, lub nres nres thiab lub nres nres, lub suab nrov yuav txo qis.Nyob rau tib lub sijhawm, kev puas tsuaj rau lub nres disc yuav txo qis.Tsis tas li ntawd, cov ntaub thaiv npog ceramic tuaj yeem nyob ruaj khov nyob rau hauv qhov kub thiab txias, tsis txhob muaj cov organic lossis hlau nres vim lub sijhawm ntev lossis kev kub ceev, vim yog lub zog nres ntawm cov khoom melting, zoo heev txhim khu kev ruaj ntseg.Nws kuj yog hnav ntau dua.
