Product Description
Silica
Silica tseem hu ua hydrated silica. Cov tshuaj formula yog SiO2·nH2O. Nws yog ib qho dawb, tsis muaj tshuaj lom, amorphous thiab nplua hmoov inorganic silicon compound nrog porosity, siab dispersibility, lub teeb yuag, thiab zoo tshuaj stability. Nws muaj cov khoom zoo heev xws li kub tsis kam, tsis-combustibility, thiab zoo hluav taws xob rwb thaiv tsev. Nws tau siv dav hauv ntau lub teb xws li plastics, roj hmab, papermaking, coatings, dyes thiab inks.

Classification ntawm Silica
Muaj ob txoj hauv kev los faib Silica, Raws li txoj kev tsim khoom, nws muab faib ua silica precipitated thiab huab cua silica; Raws li kev lag luam, silica tau muab faib ua huab cua silica, zoo tib yam precipitated silica thiab heev dispersed precipitated silica.
Daim ntawv thov
Hauv cov log tsheb
Silica yog siv los ua tus neeg sawv cev txhawb zog, thiab qhov loj tshaj plaws yog nyob rau hauv cov roj hmab, uas suav txog 70 feem pua ntawm tag nrho. Dawb carbon dub tuaj yeem txhim kho lub cev zoo ntawm cov roj hmab, txo qhov lag luam ntawm cov roj hmab, thiab txo cov rollin tsis kam ntawm lub log tsheb yam tsis poob nws txoj kev ntub dej. Hauv kev lag luam roj hmab, cov pa roj carbon dub yog cov khoom siv tau zoo heev.Ntxiv silica rau tread roj hmab ntawm cov log tsheb tuaj yeem txhim kho qhov kev txiav thiab tsim kua muag ntawm cov tread, thiab txo cov popping thiab ntog blocks. Piv nrog rau cov roj hmab uas muaj cov pa roj carbon monoxide dawb, lub dov kuj tuaj yeem txo los ntawm 30 feem pua.
Hauv xim, txheej
Silica tuaj yeem siv los ua cov tshuaj rheological additive, tiv thaiv kev daws teeb meem, pab cuam dispersant, thiab matting tus neeg saib xyuas hauv kev tsim cov xim, thiab muaj cov haujlwm ntawm thickening, tiv thaiv kev daws teeb meem, thixotropy, thiab matting. Nws tseem tuaj yeem txhim kho huab cua tsis kam thiab khawb tsis kam ntawm txheej, ua kom lub zog adhesion ntawm txheej thiab substrate thiab hardness ntawm txheej, txhim kho cov khoom tiv thaiv kev laus ntawm txheej, thiab txhim kho UV nqus thiab infrared lub teeb pom kev. yam ntxwv.
