Ceramic brake pads muaj cov hauv qab no zoo dua lwm hom nres nres:
(1) Qhov sib txawv loj tshaj plaws ntawm ceramic nres ncoo thiab tsoos nres nres yog tias tsis muaj hlau. Nyob rau hauv cov tsoos nres pads, hlau yog cov khoom uas feem ntau tsim kev sib txhuam. Lub braking quab yuam yog loj, tab sis hnav yog loj, thiab lub suab nrov yog yooj yim tshwm sim. Tom qab cov ntaub thaiv npog ceramic tau teeb tsa, tsis muaj qhov txawv txav (piv txwv li, khawb suab) thaum lub sijhawm tsav tsheb. Vim hais tias ceramic nres ncoo tsis muaj hlau Cheebtsam, cov hlau squeal ntawm tsoos hlau nres ncoo thiab mating qhov chaw (piv txwv li, brakes thiab nres discs) yog zam.
(2) Kev sib txhuam coefficient. Coefficient ntawm kev sib txhuam yog qhov tseem ceeb tshaj plaws ntawm cov khoom sib txhuam
Daim ntawv thov piv txwv ntawm ceramic nres
Qhov Performance index muaj feem xyuam rau lub peev xwm braking ntawm lub nres nres. Thaum braking, cua sov yog tsim los ntawm kev sib txhuam, thiab kev khiav hauj lwm kub nce. Cov khoom siv sib txhuam ntawm cov pawm nres dav dav cuam tshuam los ntawm qhov kub thiab txias, thiab kev sib txhuam coefficient pib txo. Hauv kev siv tswv yim, kev sib txhuam quab yuam yog txo, uas txo cov nyhuv braking. Cov khoom siv sib txhuam ntawm cov khoom siv sib tsoo zoo tib yam yog qhov tsis paub tab, thiab qhov sib txhuam coefficient siab dhau, ua rau muaj qhov tsis zoo xws li kev tswj tsis tau thaum lub sij hawm kub hnyiab, hlawv discs, khawb ntawm cov brakes, thiab lwm yam. Txawm tias qhov kub ntawm lub nres nres disc nce mus txog 650 degrees, qhov sib txhuam coefficient ntawm ceramic nres ncoo tseem yog 0.45-0.55, uas tuaj yeem ua kom lub tsheb muaj kev ua haujlwm zoo.
(3) Ceramics muaj thermal stability, tsis tshua muaj thermal conductivity, thiab zoo abrasion kuj. Kev siv lub sijhawm ntev kub yog 1000 degrees. Cov yam ntxwv no ua rau cov ceramics haum rau kev ua haujlwm siab ntawm ntau yam khoom siv ua haujlwm siab, thiab tuaj yeem ua tau raws li cov kev cai ntawm kev kub ceev, kev nyab xeeb, siab hnav-resistant brakes.
(4) Nws muaj lub zog zoo txhua yam thiab lub cev muaj zog. Muaj peev xwm tiv taus siab loj thiab shear rog. Ua ntej cov khoom sib txhuam cov khoom sib sau ua ke thiab siv, drilling, sib dhos thiab lwm yam kev ua haujlwm yuav tsum tau ua kom lub nres nres sib dhos. Yog li ntawd, nws yuav tsum tau ua kom cov khoom sib txhuam muaj lub zog txhua yam kom ntseeg tau tias tsis muaj kev tawg lossis tawg thaum ua haujlwm lossis siv.
