Cov khoom ntawm cov khoom sib txhuam
Cov khoom siv sib txhuam ntawm cov phaj sib txhuam feem ntau yog tsim los ntawm cov hlua khi, cov fibers reinforcing, kev sib txhuam kev ua tau zoo, thiab cov txheej txheem kev ua tau zoo. Cov khoom xyaw no tau ua ke los ntawm cov txheej txheem thev naus laus zis kom ua tiav lawv cov haujlwm.
Cov binder feem ntau yog xaiv los ntawm thermosetting resin thiab roj hmab, thiab nws txoj haujlwm yog los khi cov khoom hauv cov mis ua ke los tsim cov khoom muaj zog txaus, tsim nyog hardness, kub tsis kam thiab hnav tsis kam.
Kev txhawb nqa fibers yuav tsum muaj lub zog txaus thiab muaj cua sov zoo thiab ua haujlwm tsis zoo, thiab yuav tsum tsis txhob khawb qhov sib piv. Cov txheej txheem ntau qhov sib xyaw ua ke muaj xws li iav fibers, ntxhia fibers, aramid fibers thiab daim ntawv vermiculite muaj "micro thiab nano" nplai, "ib-dimensional (fiber) thiab ob-dimensional (daim ntawv)" morphology, "inorganic thiab organic" khoom thiab lwm yam ntxwv.
Kev sib txhuam kev ua haujlwm hloov kho tuaj yeem txhim kho thiab ruaj khov ntawm kev sib txhuam coefficient, xws li cov hlau tsis muaj hlau, hlau number case, av nplaum, thiab lwm yam. nyob rau hauv qhov kub thiab txias. xav tau braking quab yuam. Rau graphite, mica, talc, thiab lwm yam, nws hardness yog tsawg heev, uas plays lub luag hauj lwm ntawm lubricating qhov kev sib txhuam nto thiab stabilizing cov kev sib txhuam coefficient.
Cov txheej txheem kev ua tau zoo regulators muaj xws li tso tawm cov neeg sawv cev thiab tshwj xeeb additives. Tus neeg sawv cev tso tawm tso cai rau cov khoom tso tawm kom zoo thaum lub sijhawm tsim khoom; qhov tshwj xeeb muab tub lim txhim kho cov khoom nplaum thiab txhim kho cov khoom siv.
