Cov khoom siv silicon carbide tam sim no ntawm kev ua lag luam tseem yuav muaj cov khoom tsis huv. Hnub no kuv yuav qhia txog cov txheej txheem acid-base uas tib neeg feem ntau siv los tshem cov silicon carbide impurities:
1. Thawj yog kev khaws cov silicon carbide. Pickling feem ntau yog ua los ntawm silicon carbide hais nrog sulfuric acid hauv qab cua sov. Lub hom phiaj tseem ceeb yog tshem tawm cov hlau hlau, hlau oxide, magnesium, txhuas thiab lwm yam impurities hauv silicon carbide. Txoj hauv kev no, cov khoom tsis huv hauv silicon carbide tuaj yeem tshem tawm kom huv thiab nrawm.
2. Qhov thib ob yog alkaline ntxuav ntawm silicon carbide. Kev ntxuav cov tshuaj alkaline ntawm silicon carbide feem ntau yog nyob hauv cov cua sov, thiab cov tshuaj silicon carbide tau kho nrog NAOH. Lub hom phiaj tseem ceeb yog tshem tawm cov silicon dawb, silicon dioxide, thiab lwm yam ntawm qhov chaw, uas tuaj yeem nce cov ntsiab lus ntawm silicon carbide thiab ntxiv dag zog rau nws cov ntsiab lus silicon carbide.
Yog lawm, cov txheej txheem acid-base tsuas yog siv ntau txoj hauv kev tam sim no, thiab nws tau tshawb pom los ntawm kev coj ua txhawm rau txhim kho kev ua haujlwm zoo ntawm silicon carbide. Txhawm rau siv cov khoom lag luam zoo dua qub thiab zoo dua qub silicon carbide hauv peb cov haujlwm tsim khoom, peb kuj yuav tsum tau tshawb fawb txuas ntxiv thiab tshawb pom nrog cov neeg siv feem ntau thiab cov phooj ywg.
