Hydrophilic Fumed Silica
Kev Taw Qhia Txog Khoom
Fumed silica, los yog pyrogenic silica, colloidal silicon dioxide, yog amorphous dawb inorganic hmoov uas muaj thaj chaw tshwj xeeb, nano-scale thawj particle loj thiab qhov siab (ntawm cov khoom silica) concentration ntawm cov pawg silanol nto. Cov khoom ntawm fumed silica tuaj yeem hloov kho los ntawm kev sib xyaw nrog cov pawg silanol no.
Cov fumed silica uas muaj nyob hauv khw muag khoom muaj peev xwm muab faib ua ob pawg: hydrophilic fumed silica thiab hydrophobic fumed silica. Nws yog siv dav ua cov khoom xyaw tseem ceeb hauv ntau yam lag luam xws li roj hmab silicone, xim thiab yas lag luam.
Cov yam ntxwv tseem ceeb
1, zoo dispersion, zoo anti-sinking thiab adsorption.
2, Hauv cov roj hmab silicone: kev txhawb nqa siab, kev tsim kua muag siab, kev ua haujlwm zoo, kev pom tseeb zoo.
3, hauv cov xim: tiv thaiv kev sagging, tiv thaiv kev sib sau ua ke, txhim kho cov xim ruaj khov, txhim kho cov xim sib cais, txhim kho cov zaj duab xis adhesion, tiv thaiv corrosion, tsis muaj dej, tiv thaiv bubbling, pab ntws, txhim kho rheological tswj.
4, Siv tau rau txhua txheej xim (nplaum, txheej, kua mem) los txhim kho kev ruaj khov ntawm cov xim, txhim kho kev sib kis ntawm cov xim, txhim kho kev nplaum zaj duab xis, tiv thaiv kev xeb, tiv thaiv dej, tiv thaiv kev sib sau ua ke, tiv thaiv kev npuas, tshwj xeeb tshaj yog rau cov roj hmab silicone txhawb nqa, tus neeg sawv cev thixotropic nplaum, tus neeg sawv cev tiv thaiv kev sib sau ua ke rau cov xim.
5, rau cov kua system yuav tau txais thickening, rheology tswj, ncua, anti-sagging thiab lwm yam lub luag haujlwm.
6, Rau cov khoom siv khov kho tuaj yeem txhim kho qhov kev txhim kho, hnav-resistant thiab lwm yam.
7, Rau cov hmoov system tuaj yeem txhim kho qhov ntws dawb thiab tiv thaiv kev sib sau ua ke thiab lwm yam teebmeem. Nws kuj tseem siv tau ua cov khoom siv siab rau cov roj hmab ntuj thiab cov roj hmab hluavtaws, tshuaj thiab tshuaj pleev ib ce.
