Hnav Resistant Tabular Alumina Rau Abrasive

Tabular alumina yog ib daim ntawv siab-purity ntawm txhuas oxide uas yog tsim los ntawm sintering tabular alumina nplej ntawm qhov kub thiab txias. Nws yog cov ntaub ntawv tuab heev uas yog cov cim los ntawm nws cov thermal zoo thiab tshuaj lom neeg, muaj zog dua, thiab hnav tsis kam.

Hnav-resistant tabular alumina feem ntau yog siv los ua cov khoom siv abrasive vim nws qhov siab hardness thiab hnav tsis kam. Nws yog feem ntau siv rau hauv daim ntawv thov xws li kev sib tsoo lub log, cov cuab yeej txiav, thiab cov txheej txheem abrasive.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv cov hnav-tiv taus tabular alumina hauv cov ntawv thov abrasive yog nws qhov siab tiv taus hnav thiab puas. Nws cov hardness siab thiab tsis kam hnav ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv kev siv abrasive uas yuav tsum tau ua haujlwm siab thiab ua haujlwm ntev.
