Hydrophobic Fumed Silica
Kev Taw Qhia Txog Khoom
Fumed silica, los yogpyrogenic 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 Khoom Siv
1. Siv rau hauv cov kua dej polar nyuaj, xws li epoxy resin, polyurethane, vinyl resin, nrog cov thickening zoo thiab thixotropic nyhuv;
2. Siv ua thickening, thixotropic agent, anti-settling thiab anti-sagging hauv seamstress thiab cable adhesive;
3. Tus neeg sawv cev tiv thaiv kev tawg rau cov khoom siv ceev ceev;
4. Siv rau hauv toner rau loosening thiab anti-caking;
5. Siv rau hauv cov xim pleev kom txhim kho kev ruaj ntseg ntawm kev khaws cia;
6. Cov nyhuv ua npuas zoo heev hauv cov tshuaj defoamer;
