Dawb Carbon Black, tseem hu ua hydrated silica lossis lub teeb silica, nrog lub npe tshuaj lom neeg ntawm silicon dioxide (SiO₂), yog ib qho dawb, tsis muaj tshuaj lom, amorphous nanometer-scale hmoov. Nws tau muab lub npe tom qab nws cov tsos dawb thiab nws lub peev xwm los ua haujlwm hloov carbon black.

I. Cov Ntaub Ntawv Tseem Ceeb

• Qhov tsos: Hmoov dawb los yog granular los yog irregularly zoo li blocks.
• Cov Khoom Siv Tshuaj: Yaj hauv caustic alkalis thiab hydrofluoric acid, tsis yaj hauv dej, cov kuab tshuaj, thiab cov kua qaub (tshwj tsis yog hydrofluoric acid).
• Cov Khoom Siv Lub Cev: Ua haujlwm kub heev, tsis kub hnyiab, tsis muaj saj, tsis muaj ntxhiab, nrog rau kev rwb thaiv hluav taws xob zoo heev.
• Tus lej CAS: 10279-57-9
• Tus lej EINECS: 238-878-4

II. Cov Cheebtsam Tseem Ceeb thiab Cov Qauv

Cov khoom tseem ceeb ntawm Dawb Carbon Dub yog silicon dioxide, uas tuaj yeem sawv cev los ntawm cov mis SiO₂·nH₂O, qhov twg nH₂O muaj nyob rau hauv daim ntawv ntawm cov pab pawg hydroxyl nto. Dawb Carbon Dub yog ib yam khoom porous nrog thaj chaw loj thiab kev ua haujlwm ntawm qhov chaw.

III. Cov Txheej Txheem Npaj

Cov txheej txheem npaj ntawm Dawb Carbon Black feem ntau suav nrog txoj kev roj-theem, txoj kev nag lossis daus, thiab txoj kev rhuav tshem.

• Txoj Kev Gas-theemSiv silicon chlorides (xws li silicon tetrachloride) ua cov khoom siv raw, Dawb Carbon Black yog tsim los ntawm nplaim hydrolysis ntawm qhov kub siab. Gas-theem Dawb Carbon Black muaj qhov zoo ntawm qhov me me ntawm cov khoom me me, thaj chaw loj, thiab kev ntshiab tshuaj lom neeg siab, tab sis cov txheej txheem npaj yog qhov nyuaj thiab tus nqi kuj siab.
• Txoj Kev Nag Los: Silicon dioxide precipitate yog tsim los ntawm kev cuam tshuam sodium silicate nrog acid, thiab tom qab ntawd Dawb Carbon Black tau txais los ntawm kev lim dej, ntxuav, ziab, thiab lwm yam txheej txheem. Cov thev naus laus zis tsim khoom ntawm White Carbon Black yog mature, thiab cov khoom siv yooj yim, tab sis cov khoom muaj kev ua haujlwm tsawg thiab cov khoom me me nyuaj rau tswj.

IV. Cov Cheeb Tsam Siv

Dawb Carbon Black yog siv dav hauv ntau qhov chaw vim nws cov khoom tshwj xeeb:

1. Kev Lag Luam Roj Hmab: Dawb Carbon Dub yog ib qho tseem ceeb rau cov khoom siv roj hmab, uas tuaj yeem txhim kho lub zog, kev tiv thaiv kev hnav, kev tiv thaiv kev tsim kua muag, thiab cov khoom tiv thaiv kev laus ntawm cov khoom siv roj hmab. Nws yog siv dav hauv kev tsim cov log tsheb, vim nws tuaj yeem ua rau lub log tsheb tuav tau zoo dua thiab txhim kho kev nyab xeeb ntawm kev tsav tsheb.
2. Kev Lag Luam YasUa ib tug neeg sawv cev txhawb zog thiab muab tub lim, Dawb Carbon Black tuaj yeem txhim kho lub zog, qhov nyuaj, thiab kev hnav tsis kam ntawm cov yas, thiab txhim kho kev ua haujlwm ntawm cov yas.
3. Kev Lag Luam Txheej Txheem: Dawb Carbon Black, ua ib qho pigment filler, tuaj yeem txhim kho lub zog npog, lo, thiab tiv taus huab cua ntawm cov coatings, thiab txo cov nqi txheej.
4. Kev Lag Luam NtawvUa ib qho khoom siv zoo, Dawb Carbon Black tuaj yeem txhim kho qhov dawb, du, thiab ci ntawm daim ntawv, thiab txhim kho kev ua haujlwm luam ntawv ntawm daim ntawv.
5. Kev Lag Luam Khoom Siv Av nplaumHauv cov txheej txheem tsim cov khoom siv ceramic, Dawb Carbon Black yog siv dav hauv kev npaj cov glazes thiab lub cev, txhim kho lub zog, qhov nyuaj, thiab kev hnav tsis kam ntawm cov khoom siv ceramic.
6. Kev Lag Luam Kua XimUa ib qho pigment filler, Dawb Carbon Black tuaj yeem txhim kho lub zog npog, kev nplaum, thiab kev ruaj khov ntawm cov inks, thiab txhim kho kev ua tau zoo ntawm cov inks.
7. Kev Lag Luam Tshuaj Pleev Xim: Dawb Carbon Black, ua tus neeg sawv cev rau cov khoom sau thiab cov khoom ua kom tuab, tuaj yeem txhim kho qhov zoo nkauj, kev ruaj khov, thiab kev xav ntawm cov tshuaj pleev ib ce, tswj cov roj ntawm daim tawv nqaij, thiab txhim kho qhov zoo ntawm daim tawv nqaij.
8. Kev Lag Luam Tshuaj: Dawb Carbon Black feem ntau yog siv rau hauv kev npaj cov tshuaj formulations, txhim kho kev sib kis, kev ruaj khov, thiab bioavailability ntawm cov tshuaj, thiab txo cov kev mob tshwm sim.
