Hydrated silica uas yog hloov chaw ntawm cov tshuaj pleev ib ce

Precipitated silica: tseem hu ua hydrated silica, ua haujlwm silica, precipitated silica, thiabPrecipitated Fydrated Sai.

English Lub Npe: Silica (silicon dioxide).

Molecular mis: sool2 · nhh2o;

Tus lej lej: 7631-86-9.

Silica yog cov hmoov av cov hmoov dawb, x {{{pay, thiab cov khoom siv hluav taws xob, thiab cov khoom siv hluavtaws zoo nkauj, thiab cov hmoov hluavtaws zoo nkauj thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicate thiab calcium silicated. Silica yog cov khoom siv ntxeem tau uas muaj cov khoom muaj peev xwm qhia tau raws li Sio2 * Nh2o, uas nh2o muaj li cov pab pawg hydroxyl. Nws yog soluble hauv caustic alkali thiab hydrofluoric acid, tab sis insoluble hauv dej, cov kuab tshuaj, thiab cov acids (tshwj tsis yog hydrofluoric acid). Nws yog cua sov - tiv taus, tsis- nplej, thiab tsw, thiab muaj hluav taws xob hluav taws xob.

Cov microbead yas tau raug txwv tsis pub muaj kev txhawj xeeb ib puag ncig, thiab silica tau siv dav ua cov khoom noj kom zoo nkauj.

Silicon Dioxideyog gras (feem ntau lees paub tias muaj kev nyab xeeb) muaj nyob rau hauv cov khoom saib xyuas tus kheej xws li Tshuaj pleev ib ce thiab Sunscreens. Nws cov duab kheej kheej, cov portic me me, thiab siab porosity ua rau nws anti - Caking nyob rau hauv cov tshuaj pleev ib ce. Nws tuaj yeem txhim kho kev cia khoom ruaj khov thiab qhov tawg ntawm cov khoom hmoov. Nws yog dav siv nyob rau hauv cov ntawv thov xws li Dispensing Pigments thiab cov tshuaj pleev ib ce, txhim kho cov txheej txheem plaub hau, thiab txhim kho cov txheej ntawm cov plaub hau polish.
