Cov ntaub ntawv nres thiab lawv cov yam ntxwv
Cov ntaub ntawv sib txhuam ntawm cov kab nres nres yuav tsum sib npaug xws li kev sib txhuam ruaj khov, cov suab kub ua tau zoo, suab nrov tsawg, thiab cov hmoov av tsawg. Kev faib tawm cov ntaub ntawv ib txwm muaj raws li hauv qab no:
Asbestos - Raws cov ntaub ntawv
Dav siv nyob rau hauv thaum ntxov hnub, Asbestos muaj zog tiv thaiv tshav kub (nrog} 400}℃coefficients, thiab tus nqi qis. Txawm li cas los xij, asbestos plua plav tuaj yeem ua rau lub ntsws mob ntsws (xws li mob ntsws asthsosis), yog li lawv tau raug txwv nyob hauv ntau lub tebchaws. Tam sim no, lawv tsuas yog siv tsis tshua tau siv nyob rau hauv cov xwm txheej tshwj xeeb (piv txwv li, siab-ntsuas hnyav tov).
Semi - Nws yog xim hlau
Ua nrog hlau fibers (piv txwv li, cov npluav tawv ntoo), tooj liab nrog cov resins thiab kev sib txhuam ua lag luam (nyiaj txiag rau ntau dua 70%).
Qhov Zoo: Zoo siab - qhov kub thiab txias (nrog rau cov neeg muaj zog), haum rau cov tsheb tsis kam, thiab cov tsheb lag luam feem ntau.
Tsis zoo: Cov ntsiab lus hlau siab (txog 30% -60%) yuav ua kom nrawm nrawm disc hnav, thiab suab nrov me ntsis ntawm cov kub tsawg.
Tsawg - cov ntaub ntawv metallic
Txo cov kev faib ua feem ntawm cov hlau cov hmoov (feem ntau yog qis dua 20%) thiab nce cov organic fibers (piv txwv li aramid fibers) thiab cov pob zeb hauv av (ntxhia cov pob zeb kom sib npaug thiab kev nplij siab.
Qhov Zoo: Ntau ruaj khov sib txhuam coefficient, cov suab nrov tsawg, thiab tsis tshua muaj rau cov qauv tsom mus rau ntsiag to thiab xis nyob (xws li tsheb kim heev).
Tsis zoo: Qis dua me ntsis siab - kub tsis kam tshaj li semi- nws tus nqi me me.
Cov Khoom Siv Tej Heraug
Mainly composed of ceramic fibers and inorganic fillers, mixed with a small amount of metal powder (eg, copper powder), belonging to high-end friction materials.
Qhov Zoo: Zoo heev rau siab - qhov kub tiv thaiv (muaj cov suab nrov tsawg, haum rau kev sib tw tsheb thiab siab ua si cov tsheb sib tw thiab cov kev ua si siab.
Tsis zoo: Cov nqi siab (txog li 2 - 3 1 lub sij hawm ntawm semi-metallic cov ntaub ntawv), thiab me ntsis qeeb state braking teb ntawm tsawg kub.
Tag Nrho Cov Ntaub Ntawv Ceramic
Kiag li dawb ntawm cov hlau, nrog cov sib xyaw ua ke thiab cov cav ntoo ua ke raws li cov tub ntxhais, tsuas yog siv nyob rau hauv cov tsheb ciav hlau ntau xws li kev sib tw tsheb.
Qhov Zoo: Kev kub siab tsis kam (ntau dua 1000 degree), lub teeb yuag, thiab muaj kev sib txhuam tsis muaj zog.
Tsis zoo: Tus nqi siab heev, tsis tshua muaj kev sib txhuam coefficient ntawm tsawg kub, thiab tsis tsim nyog rau kev siv hauv txoj kev niaj hnub.
Organic cov ntaub ntawv (no cov ntaub ntawv, tsis - asbestos organic cov ntaub ntawv)
Raws li cov organic fibers (piv txwv li, resin fibers, paj rwb fibers), tov nrog roj hmab thiab graphite.
Qhov Zoo: Lub suab tsis tshua muaj suab, thiab yuav luag tsis muaj kev hnav rau cov tsheb nres, cov tsheb ceev, cov tsheb hluav taws xob, cov tsheb hluav taws xob, cov tsheb hluav taws xob, Nroog Nroog loj).
Tsis zoo: Cov siab tsis zoo - qhov kub tsis kam tshaj 300 tawm tsam kev ua haujlwm siab dua 300 2} {{l} backing braking.
