Qhov Sib Txawv Ntawm Cov Pa roj Carbon Dub Dawb thiab Silicon Dioxide
Silicon Dioxide (SiO2) yog ib lo lus dav dav rau silicon oxides hauv chemistry, pom dav hauv xwm (piv txwv li, quartz, xuab zeb, siv lead ua) thiab kuj tuaj yeem npaj tau synthetically. Nyob ntawm cov qauv thiab morphology, silicon dioxide tuaj yeem faib ua cov ntaub ntawv crystalline (piv txwv li, quartz) thiab daim ntawv amorphous ...Nyeem ntxiv -
Kev Tshawb Fawb Txog Kev Lag Luam Precipitated Silica
Precipitated silica, feem ntau hu ua dawb carbon dub, hydrated silica, lossis lub teeb silica, tsis yaj hauv dej thiab feem ntau cov kua qaub. Nws nqus cov dej noo hauv huab cua los ua cov khoom me me thiab yaj hauv caustic soda thiab hydrofluoric acid. Nws tseem ruaj khov tiv thaiv lwm yam tshuaj lom neeg, tiv taus...Nyeem ntxiv -
Kev Taw Qhia Txog Carbon Black
Cov pa roj carbon dub, hu ua tus sawv cev ntawm cov pa roj carbon amorphous, yog cov hmoov dub sib dua, fluffy nrog thaj chaw loj. Nws feem ntau yog tsim los ntawm kev sib xyaw tsis tiav lossis thermal decomposition ntawm cov tshuaj uas muaj cov pa roj carbon (xws li thee, roj av, roj hnyav, thiab lwm yam) nyob rau hauv cov xwm txheej ntawm ...Nyeem ntxiv -
Lub Luag Haujlwm Tseem Ceeb ntawm Carbon Black hauv Cov Log Tsheb
Cov pa roj carbon dub yog ib qho ntawm cov khoom siv tseem ceeb hauv kev tsim cov log tsheb, feem ntau yog ua tus neeg sawv cev txhawb nqa thiab cov khoom sau. Nws ua rau lub log tsheb ua haujlwm tau zoo dua, suav nrog lub zog, kev tiv thaiv kev hnav, kev tiv thaiv kev laus, thiab kev tiv thaiv kev qaug zog. Cov pa roj carbon dub yog dab tsi? Cov pa roj carbon dub yog cov pa roj carbon-...Nyeem ntxiv -
Nws ua tau los hloov barium chloride nrog calcium chloride hauv kev tshuaj ntsuam da dej
1. Kev Txheeb Xyuas Sodium Hydroxide Tau ob lub hlis, ob lub tshuaj reagents tau raug sim ua ke thaum tshuaj xyuas cov qauv rau cov neeg siv khoom. Cov txiaj ntsig ntawm kev tshuaj xyuas ntawm cov ntsiab lus Sodium Hydroxide qis dua yeej zoo ib yam, thaum qhov sib txawv ntawm cov ntsiab lus sodium hydroxide siab dua yog w ...Nyeem ntxiv
