Koj puas paub dab tsi txog cov ntaub ntawv sib xyaw hauv cov pawm nres?
Nrog rau qhov kev nthuav qhia ntawm cov kis tau tus mob, nws txhais tau hais tias lub dominance ntawm lub nres nres. Nws tuaj yeem hais tau tias qhov twg muaj cov khoom siv kis tau tus mob, muaj lub nres nres kom muaj kev nyab xeeb.
Puas yog cov brakes ua los ntawm cov khoom sib xyaw? Yog, nws yog ib qho khoom siv zoo heev. Vim hais tias cov formulation feem ntau muaj xws li ib tug fiber ntau thiab ib tug functional modifier, cov resin ces siv raws li ib tug binder rau kub dov.
Yog li yuav ua li cas thiaj tsim tau cov brakes? Pib los ntawm cov khoom siv ntawm cov khoom siv nres, cov khoom sib xyaw ua ke tuaj yeem muab faib ua asbestos thiab non-asbestos. Txawm li cas los xij, vim tias asbestos tsis yog ib puag ncig tus phooj ywg thiab tsim kev puas tsuaj rau tib neeg kev noj qab haus huv, txij li nruab nrab -1970s mus rau nruab nrab -1980s, lub teb chaws pib siv cov tshuaj uas tsis yog asbestos.
Tam sim no, muaj peb yam uas tsis yog-asbestos formulations: semi-metallic, oligo-metallic thiab non-metallic. Rau lub brake liner, dab tsi tus neeg siv xav tau yog qhov zoo heev hnav tsis kam, siab zog kub cheeb tsam tom qab tsis sib haum xeeb thaum tshav kub kub tsim, thiab tam sim no ntau thiab ntau xim rau lub suab nrov teeb meem. Nrog rau kev txhawj xeeb ntau ntxiv ntawm cov teeb meem suab nrov, ntau lub tuam txhab thiab cov chaw tshawb fawb tau siv zog tsim NAO cov qauv, cia siab tias qhov kev ua haujlwm ntawm qhov kub thiab txias kuj tuaj yeem ua raws li qib qub. Qhov zoo ntawm cov mis hlau me me yog cov cua kub sai sai, cov coefficient tsis sib haum xeeb, lub suab nrov, thiab kev puas tsuaj loj rau disk. Muaj ntau cov khoom siv organic hauv cov mis tsis yog xim hlau, tab sis nws yooj yim rau carbonize nyob rau hauv qhov kub thiab txias, thiab nws txoj haujlwm txo qis. Nyob rau hauv lub formulation peb tsim, phenolic resins nrog zoo heev kub kuj tau siv.
Lwm cov khoom xyaw thiab cov khoom siv sib xws yog raws li hauv qab no: Cov khoom siv fiber ntau: carbon fiber, aramong fiber, steel fiber, composite fiber Conflict agent: conflict particles, zirconia (oxide, kim dua alumina, tab sis tsawg nrov), magnesium oxide, potassium hexatitanate whisker lubricant : tooj liab sulfide, dag graphite (kom txo cov kev puas tsuaj rau lub disk) Lwm yam regulators: Nitrile hmoov, 2-8 tooj dag hmoov, barium sulfate, carbonate Nyob rau hauv lub tiag tiag calcium ntau lawm txheej txheem, tus engineer yuav hloov qhov kev faib ua feem thiab hom. cov ntaub ntawv qub raws li cov neeg siv khoom xav tau rau kev sib tsoo coefficient thiab cov suab nrov suav cov qauv, thiab tom qab ntawd tsim cov qauv me me rau kev sim, thiab tom qab ntawd txhim kho, sim, thiab tom qab ntawd yuav tsim thiab muag.
