Hydrophobic Fumed Silica
Khoom Taw Qhia
Fumed silica, los yogpyrogenic silica, colloidal silicon dioxide, yog amorphous dawb inorganic hmoov uas muaj qhov tshwj xeeb ntawm thaj chaw, 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 qhov kev lag luam xws li silicone roj hmab, xim thiab plastics industries.
Khoom Khoom
1. Siv nyob rau hauv complex polar kua, xws li epoxy resin, polyurethane, vinyl resin, nrog zoo thickening thiab thixotropic nyhuv;
2. Siv raws li thickening, thixotropic tus neeg saib xyuas, los tiv thaiv kev daws teeb meem thiab tiv thaiv sagging hauv seamstress thiab cable nplaum;
3. Tus neeg saib xyuas kev daws teeb meem rau high-density muab tub lim;
4. Siv rau hauv toner rau loosening thiab anti-caking;
5. Siv rau hauv cov xim los txhim kho kev ruaj ntseg cia;
6. Cov nyhuv defoaming zoo heev hauv defoamer;
