Ntawv thov ntawmsilica hauv tshuaj txhuam hniav
Vim tias kev ruaj khov ntawm cov yam ntxwv ntawm lub cev ntawm silica, nws zoo ib yam li ntawd hauv tshuaj txhuam hniav.
Qhov sib xyaw thiab kev sib txuam ntawm cov tshuaj thiab lwm yam khoom siv yog qhov zoo, thiab qhov zoo ntawm cov tshuaj txhuam tau ruaj khov.Yog li ntawd, silica yog dav siv tshuaj txhuam hniav.
Ntau hom oxidation tuaj yeem tsim nyob rau hauv cov txheej txheem sib txawv
Silicon, xws li txhuam yam, hom tuab, hom sib xyaw, hais ntawm ntau qhov sib txawv, thiab lwm yam. Lawv tuaj yeem siv txhua hom tshuaj txhuam hniav. I. Feem ntau nws siv cov tshuaj txhuam hniav hauv cov hauv qab no:
Raws li qhov tseeb tias silicon dioxide thiab fluorine muaj qhov sib xyaw tau zoo, cov txiaj ntsig tau pom tias cov ntsiab lus ntawm cov tshuaj fluorine zoo tuaj yeem khaws cia ntev ntev. Yog li, silica yog thawj qhov kev xaiv rau cov tshuaj txhuam hniav fluoride.Thiab nws txoj kev ruaj ntseg rau cov tshuaj fluoride tuaj yeem muab kev ua si rau cov tshuaj fluoride caries zoo.
Nyob rau hauv xyoo tas los no, nrog kev txhim kho tas mus li ntawm qhov zoo ntawm silica hauv tsev thiab qhov nce ntawm ntau yam thiab cov qauv, nws muab cov xwm txheej zoo rau peb txhim kho cov tshuaj txhuam hniav pob tshab nrog cov silica hauv tsev tsis txhob siv cov tshuaj silica. Los ntawm kev sib piv kev sib txawv, peb ntseeg hais tias kev ua kom thaj chaw ntawm cov tshuaj txhuam hniav pob tshab nrog silica yog ua tau, uas tsis tsuas yog txo cov nqi thiab txiaj ntsig zoo, tab sis kuj txhim kho qhov muab tshuaj' s zoo los ntawm kev kho qhov sib piv ntawm silica hauv cov mis. Dispersion thiab tsos zoo. Peb tab tom tsim cov tshuaj txhuam hniav anti calculus. Nyob rau hauv kev ua kom cov tshuaj txhuam hniav ntxuav hniav dawb, ntxiv cov nqi tsim nyog ntawm cov ntxhib ntxoo thiab cov ntsiab lus siab silica tuaj yeem txhim kho kev ua haujlwm zoo, nce kev sib txhuam thiab txhim kho lub peev xwm ntawm kev ntxuav hniav.
Daim ntawv thov ntawm kev txhuam txhuam silica hauv calcium cov tshuaj txhuam hniav
Vim tias qhov tshuaj txhuam hniav tsawg tus nqi ntawm cov tshuaj txhuam hniav tsuas yog siv cov calcium hydroxide ua tus neeg sawv cev txhuam, tus nqi txhuam ntawm cov tshuaj txhuam hniav tau nce siab ntxiv tom qab siv txhuam silica. Nyob rau tib lub sijhawm, nws tseem ua tiav cov txiaj ntsig txaus hauv kev txhim kho tus qauv thiab tsos ntawm kev muab tshuaj txhuam.
Daim ntawv thov ntawm cov tuab silica nyob rau hauv cov tshuaj txhuam hniav
Siv nws cov cuab yeej ua kom tuab, peb tuaj yeem siv nws ua ke nrog cov inorganic gel los siv hauv cov tshuaj txhuam hniav, uas tuaj yeem txo qhov ntau npaum li cas ntawm qee cov thickeners, thiab txhim kho cov tshuaj kom zoo thiab tawg ntawm cov muab tshuaj.
Hauv kev xaus, silica tau siv dav hauv cov tshuaj txhuam hniav. Nrog kev tsim kho tas mus li ntawm cov tshiab ntawm silica rau cov tshuaj txhuam hniav thiab kev txhim kho tas li ntawm cov khoom qub ntawm silica, peb ntseeg tias daim ntawv thov kev cia siab ntawm silica hauv tshuaj txhuam hniav yuav ntau dua thiab ci dua.
