Dab tsi yog qhov sib txawv tseem ceeb ntawm alumina thiab silicon carbide polishing abrasives?

Hardness thiab hnav tsis kam:
Lub hardness ntawm silicon carbide abrasive yog siab dua li ntawm txhuas oxide abrasive. Nws mohs hardness tuaj yeem ncav cuag li ntawm 9.4, uas tsuas yog ob rau pob zeb diamond. Yog li nws tau hnav ntau dua - tsis kam. Qhov no txhais tau tias cov ablicon carmide carrasive tuaj yeem ua kom zoo dua cov duab thaum sib tsoo thiab yog qhov zoo rau kev ua cov ntaub ntawv nyhav.
Txawm hais tias txhuas oxide abrasive kuj yog qhov nyuaj heev, nws yog me ntsis softer piv rau silicon carbide. Nws mohs hardness yog kwv yees li qib 9. Tab sis tseem muaj abside o} ceev thiab hnyav {{luas} Kev ruaj nroo thiab nyeem cov khoom sib tsoo.

Sib tsoo efficiency:
Vim tias Silicon carbide abrasive yog qhov nyuaj heev, nws sib tsoo efficiency yog qhov tsawg. Thaum muaj ntau cov khoom siv yuav tsum tau muab tshem tawm sai sai, koj yuav xav xav txog lwm cov abarasives lossis kho cov txheej txheem tsis sib xws.
Aluminium OBIDID ABRAST yog cov softer, tab sis nws tuaj yeem muab kev sib tsoo siab dua. Thaum koj yuav tsum tau txais cov nyhuv polishing tau sai sai, txhuas oxide athide abrasas tuaj yeem yog qhov kev xaiv zoo.

Nqe thiab Khoom:
Silicon carbide Abrasas feem ntau kim dua li txhuas oxide abrasive, thiab hauv qee thaj chaw, nws yuav yog qhov khoom tsis txaus. Qhov no tej zaum yog vim tias cov txheej txheem ntau lawm ntawm Silicon Carbide Abrasive yog ntau dua thiab tus nqi ntawm cov khoom raw yog siab dua.
Aluminium Oxide Abrasive yog tus pheej yig dua thiab muaj ntau yam muaj. Yog li aluminium oxide abrasive muaj qhov kom zoo rau cov ntawv thov uas tus nqi yog qhov kev txhawj xeeb loj.

Particle loj thiab faib:
Lub particle me me ntawm silicon carbide abrasas feem ntau loj dua thiab nws tuaj yeem tshem tawm cov chaw tsis ncaj ncees sai. Tab sis qhov no yuav txhais tau tias koj xav tau cov abrasive me me hauv kev nplua polishing theem kom tau txais lub zoo tagnrho nto smoothness.
Lub particle loj ntawm txhuas oxide Abrasive yog finer thiab cov particle faib yog txawm. Qhov no ua rau txhuas oxide abrasive muab ib qho zoo dua nto zoo hauv kev nplua polishing theem.

Tshuaj lom neeg ruaj khov thiab corrosion Kuj:
Aluminium Oxide Abrasive yog ruaj khov tawm tsam acids, hauv paus thiab qee lwm yam tshuaj lom neeg. Yog li nws haum rau kev siv nyob rau hauv kev xeb ib puag ncig. Qhov no ua rau txhuas oxide abrasive zoo dua thaum cuam tshuam cov ntaub ntawv uas yog rhiab rau corrosion.
Silicon carbide abratas kuj muaj qee cov tshuaj lom neeg ua haujlwm, tab sis nws yuav tsawg dua li txhuas oxide. Tab sis silicon carbide abrasas kuj tseem tuaj yeem ceev cov cev nqaij daim tawv thiab tshuaj siv thaum muaj qhov kub thiab txias thiab kub}}}}} qhov chaw dej khov.
