Hydrophilic Fumed Silica
Khoom Taw Qhia
Fumed silica, los yog pyrogenic silica, colloidal silicon dioxide, yog amorphous dawb inorganic hmoov uas muaj qhov tshwj xeeb saum npoo av, nano-scale thawj particle loj thiab ib tug kuj siab (ntawm silica khoom) concentration ntawm nto silanol pawg. Cov khoom ntawm fumed silica tuaj yeem hloov kho los ntawm cov tshuaj tiv thaiv nrog cov pab pawg silanol.
Kev lag luam muaj fumed silica tuaj yeem muab faib ua ob pawg: hydrophilic fumed silica thiab hydrophobic fumed silica. Nws yog dav siv los ua cov khoom tseem ceeb hauv ntau lub lag luam xws li silicone roj hmab, xim thiab plastics industries.
Cov yam ntxwv tseem ceeb
1, zoo dispersion, zoo anti-sinking thiab adsorption.
2, Silicone roj hmab: siab zog, siab kua muag tsis kam, zoo abrasion kuj, zoo transparency.
3, nyob rau hauv cov xim: anti-sagging, los tiv thaiv kev daws teeb meem, txhim kho pigment stability, txhim kho pigment dispersion, txhim kho zaj duab xis adhesion, anti-corrosion, waterproof, tiv thaiv bubbling, pab txaus, txhim khu rheological tswj.
4, Muaj feem xyuam rau txhua txheej xim (nplaum, txheej, number case) los txhim kho cov xim ruaj khov, txhim kho cov xim dispersion, txhim kho zaj duab xis adhesion, anti-corrosion, waterproof, anti-settling, anti-bubbling, tshwj xeeb tshaj yog rau silicone roj hmab reinforcing, nplaum thixotropic agent, anti-settling agent rau coloring system.
5, rau cov kua dej tuaj yeem tau thickening, rheology tswj, ncua kev kawm ntawv, anti-sagging thiab lwm yam luag hauj lwm.
6, Rau cov khoom siv tuaj yeem txhim kho kev txhim kho, hnav-tiv taus thiab lwm yam.
7, Rau cov hmoov txheej tuaj yeem txhim kho qhov dej dawb thiab tiv thaiv agglomeration thiab lwm yam teebmeem. Nws tseem tuaj yeem siv los ua cov khoom ua kom muaj zog rau ntuj thiab hluavtaws roj hmab, tshuaj thiab tshuaj pleev ib ce.
