Dab tsi yog Qhov Sib Nqus Hauv Cov Nres Nres Nres
Dab tsi yog qhov aggregate nyob rau hauv lub brake pad? Ntau npaum li kaum hom khoom raw yog ntxiv rau lub nres nres. Nws yog tsim los ntawm cov khoom sib txhuam. Cov khoom sib txhuam tsuas yog cov khoom tseem ceeb, tseem hu ua aggregate. Xyoo 1972, World Medical Seminar tau lees paub tias asbestos fiber tuaj yeem cuam tshuam rau tib neeg kev noj qab haus huv. Nyob rau tib lub xyoo, tsoomfwv thoob plaws ntiaj teb tau siv txoj cai txwv rau cov plua plav asbestos. Qhov zoo: tus nqi qis; Qhov tsis xws luag: teeb meem rau tib neeg lub cev, qeeb cua sov dissipation;
Semi-hlau nres pads yog ua los ntawm crude steel fiber ua ib qho tseem ceeb sib tov, thiab muaj ib co sib nqus tsis xws luag: yooj yim xeb, yooj yim suab nrov, tsis kub. Lub brake disc yog hnav ntau dua, thiab lub braking quab yuam yuav tsum tau ntau dua; Qhov zoo: zoo thermal conductivity, haum rau high-temperature braking;
Cov hlau muaj pes tsawg leeg ntawm cov hlau nres nres yog txo, thiab qee qhov tsis xws ntawm tooj liab hmoov thiab steel velvet yog siv. Qhov hnav tsis kam yog tsawg. Qhov zoo yog zoo thermal conductivity thiab kub dissipation, tsis tshua muaj suab nrov, zoo braking kev nplij siab, thiab ruaj khov coefficient;
Cov khoom siv hluav taws xob ntawm Nao ceramic nres ncoo tsis muaj asbestos feem ntau yog siv iav fiber ntau, txias aromatic polyester fiber los yog lwm yam fibers (carbon, ceramic) ua cov ntaub ntawv ntxiv, thiab feem ntau siv ceramic nres ncoo. Nws txoj haujlwm tsuas yog nyob ntawm hom fiber ntau thiab lwm yam khoom ntxiv. Tus nqi ntawm ceramic brakes yog siab heev. Tsis muaj ntshiab ceramic nres ncoo hauv Suav teb tom qab kev muag khoom. Ntshiab ceramic nres ncoo yog siv rau kev sib tw.
Hmoov metallurgy nres ncoo thiab cov pa roj carbon monoxide yog siv rau kev kub ceev tsheb ciav hlau thiab dav hlau. Qhov zoo thiab qhov tsis zoo ntawm cov ntaub ntawv tsis sib haum xeeb yog qhov tseem ceeb hauv kev tsis sib haum xeeb, kev qaug zog thiab kub, rhiab heev rau lub siab thiab ceev, hnav tsis kam thiab suab nrov. Qhov zoo dua ntawm cov ntaub ntawv tsis sib haum xeeb, qhov zoo dua qhov kev tsis sib haum xeeb ua haujlwm nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, siab thiab ceev. Hauv lwm lo lus, nws txoj haujlwm yuav tsum tsis txhob hloov pauv ntau ntawm qhov qis lossis kub siab. Qhov zoo dua ntawm cov ntaub ntawv tsis sib haum xeeb, qhov tsis tshua muaj tus nres yuav luv dua tom qab rov ua dua, uas yuav ua rau "brake pedal" zoo.
Cov ntaub ntawv zoo dua tuaj yeem txo qhov hnav thiab suab nrov. Xaiv ib khub ntawm kev ua haujlwm siab nres kom ntseeg tau tias muaj txiaj ntsig zoo ntawm kev sib tsoo thiab kev nyab xeeb ntawm kev tsav tsheb hauv ntau qhov chaw!
