Kev piav qhia
Silicon carbide yog cov khoom siv abrasive nrov siv hauv ntau hom kev lag luam thiab kev lag luam. Nws yog cov khoom siv tawv thiab nkig nrog lub siab melting point, ua rau nws tsim nyog siv rau hauv cov khoom siv abrasive xws li kev sib tsoo log, ntawv xuab zeb, thiab cov cuab yeej txiav.
Silicon carbide abrasive hmoov yog cov khoom zoo thiab qib abrasive uas yog siv los tsim cov khoom abrasive. Nws feem ntau yog ua los ntawm crushing thiab muab qhab nia zoo silicon carbide crystals rau hauv cov hmoov zoo.
Cov hmoov tom qab ntawd siv rau hauv kev tsim cov khoom abrasive xws li kev sib tsoo log, ntawv xuab zeb, thiab cov cuab yeej txiav. Nws kuj tseem siv rau hauv kev lag luam xws li metallurgy, ceramics, electronics, thiab automotive manufacturing.
Silicon carbide abrasive hmoov muaj ntau qhov zoo dua lwm cov ntaub ntawv abrasive, nrog rau kev ua haujlwm siab, siab thermal conductivity, tsis tshua muaj thermal expansion, thiab tshuaj lom neeg zoo heev. Cov khoom no ua rau nws zoo tagnrho rau siv nyob rau hauv ib puag ncig hnyav, kev siv kub kub, thiab kev siv siab.
