Nres Pad tuam ntxhab coj koj kom nkag siab txog cov coj tsis kam ntawm nws txoj kev ua haujlwm ntawm nws lub neej, tab sis kuj tseem ceeb ntawm cov ntaub ntawv teeb meem los ntsuas cov ntaub ntawv teeb meem. The better the wear resistance, the longer its service life. Txawm li cas los xij, kev hnav tso cov khoom sib txhuam thaum lub txheej txheem ua haujlwm yog tshwm sim los ntawm lub zog shear

Operating temperature is an important factor of hard wear. Thaum lub qhov kub ntawm cov ntaub ntawv nce mus txog cov cua sib txawv ntawm cov organic nplaum, cov roj hmab thiab cov roj hmab yuav sib txawv, hluav taws xob thiab poob ceeb thawj. Nrog kev nce ntawm qhov kub, qhov kev ua tau zoo no txo ​​qis, thiab tus nqi ntawm kev hnav nce siab ntxiv, uas hu ua thermal hnav.

Cov kev xaiv ntawm cov tsim nyog tiv thaiv fasters, resins thiab rub cov khoom siv kub ua kom tau zoo dua cov khoom siv ua haujlwm, tshwj xeeb tshaj yog cov hnav cua sov, thiab nthuav lawv lub neej.
