Dab tsi yog kev siv ntawm silica hauv tshuaj pleev ib ce?
Cov tshuaj inertness thiab tshwj xeeb thixotropy ntawm silicon dioxide tau txhim kho lub zog tensile, tsim kua muag thiab hnav tsis kam ntawm cov khoom siv roj hmab, thiab lub zog ntawm cov roj hmab tom qab kev txhim kho tau nce ntau ntau zaus. Lub rheology thiab thixotropy tswj cov kua tshuab, nplaum thiab polymers yog siv los tiv thaiv sedimentation, thickening thiab anti sagging additives. Dab tsi yog kev siv ntawm silica hauv tshuaj pleev ib ce?
1. Silica thiab ntsia thawv polish
Hauv cov ntsia thawv polish, silica tuaj yeem ua kom cov xim sib txawv ntawm cov xim hauv cov xim ci, tiv thaiv pigmentation, thiab muab cov rheology ntawm cov khoom kawg, yog li txhim kho cov txheej txheem kev ua haujlwm. Yog hais tias lub refractive index ntawm cov kuab tshuaj system yog tib yam li silica (1). 48), pob tshab ntsia thawv polish qauv tuaj yeem tsim, xws li xim tom qab thiab lub ntsej muag xim. Txwv tsis pub, thaum lub concentration siab, nws yuav npub, tab sis nws yuav txo qhov yuav tsum tau gloss. Cov khoom siv hydrophilic thiab hydrophobic silica tuaj yeem siv rau hauv cov ntsia thawv polish, thiab cov lus pom zoo yog nyob nruab nrab ntawm 0 25-4 0 feem pua .
2. Silica thiab mem pleev di ncauj
Hauv daim di ncauj, silica tuaj yeem ua rau cov xim sib npaug sib npaug, txhim kho qhov kub thiab txias, thiab tiv thaiv daim di ncauj los ntawm softening thaum kub nce. Tom qab tau smeared ntawm daim di ncauj, nws tuaj yeem tiv thaiv daim di ncauj los ntawm kev hloov mus rau daim di ncauj me me, yog li daim di ncauj yuav tsis ploj mus ntev. Thaum lub concentration siab, lub gloss yuav poob.
3. Silica thiab kho qhov muag
Rau ntau lub qhov muag thiab lub ntsej muag tshuaj pleev ib ce, nrog rau zib mu hmoov, foundation make-up, rouge, qhov muag dub thiab eyeliner, silica yog ib tug npaum anti caking tus neeg saib xyuas thiab dawb ntws tus neeg sawv cev, uas yuav txhim khu kev ruaj ntseg cia thiab dispersibility ntawm hmoov khoom. Nws kuj tseem ua rau cov tshuaj pleev ib ce siv cov xim, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm cov khoom muaj zog, uas nws thiaj li siv tau los ua cov khoom siv ntxiv rau kev sib tsoo thiab lim cov hmoov.
