Taw qhia rau kev siv cov khoom sib txhuam

Cov ntaub ntawv asbestos tau dav siv los ua cov ntaub ntawv sib txhuam rau lub tsheb nres tsheb. Txawm hais tias nws cov load-cov kabmob muaj peev xwm tsis zoo li cov khoom siv hmoov metallurgy, nws muaj kev sib txhuam coefficient siab thiab kaw dynamic thiab zoo li qub kev sib txhuam coefficients, uas tuaj yeem ua rau braking ruaj khov, tsis tshua muaj suab nrov, thiab tus nqi qis.

Nws tuaj yeem ua haujlwm ib txwm nyob rau hauv siab load thiab kub, thiab tshwj xeeb tshaj yog paub rau nws ruaj khov kev sib txhuam coefficient thiab zoo hnav tsis kam. Yog li ntawd, nws yog siv los ua brakes rau lub dav hlau tsaws, pob ntsia hlau txhuam daim hlau rau hnyav loads, thiab clutch phaj rau hluav taws xob mechanisms.

Nyob rau hauv kev thauj mus los machinery xws li tsheb, nkoj, tsheb ciav hlau, loj thiab nruab nrab- loj siv machinery xws li bulldozers, mine elevators, excavators thiab tsheb laij teb, ua liaj ua teb machinery, thiab lub teeb industrial machinery, ntau yam specifications thiab hom hmoov metallurgy kev sib txhuam discs , brake pads, thiab lwm yam. Ntxiv nrog rau kev ua tiav zoo ntawm clutch thiab braking, nws tseem tuaj yeem txo lub zog noj thiab txhim kho kev sib kis tau zoo. Nrog rau kev txhim kho cov cuab yeej siv niaj hnub no, qhov kev thov siab rau - cov ntaub ntawv sib txhuam ua haujlwm tau dhau los ua qhov nrawm dua.

The carbon-carbon composite material that appeared in the late 1970s is a promising friction material. It has stable high-temperature friction performance, long life, and light weight. It has been successfully used in the braking devices of Concorde and Boeing aircraft. It's just that the price is expensive, which affects the wide range of applications. Graphite-based friction material with good performance under medium load, low temperature and wet friction conditions is also a new type of material with great development prospects. It has almost all the advantages of asbestos and powder metallurgy materials at present, and the price is cheap, and it is an ideal friction material.
