Vim li cas cov tshuaj pleev ib ce nyiam hemispherical silica?
Vim li cas spherical silica zoo? Vim nws cov nyiaj filling ntau, zoo fluidity, tsis tshua muaj thermal expansion coefficient thiab tsis tshua muaj kev ntxhov siab, nws yog dav siv nyob rau hauv lub teb ntawm tooj liab clad phaj thiab epoxy yas sealing khoom muab tub lim nyob rau hauv loj-scale integrated circuit ntim. Tab sis qee zaum, spherical silica yuav raug cuam tshuam los ntawm cov yam ntxwv no thiab ua tsis tshua muaj txiaj ntsig, xws li tshuaj pleev ib ce.
Txawm hais tias spherical silica tuaj yeem ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw, hauv kev lag luam tshuaj pleev ib ce, nws lub luag haujlwm tsis zoo li hemispherical silica.
Qhov sib txawv loj ntawm spherical silicon dioxide thiab hemispherical silicon dioxide yog cov duab, yog li cov nyhuv kuj txawv, thiab daim duab hauv qab no tuaj yeem pom qhov sib txawv ntawm ob qhov zoo li cas.
Vim li cas cov tshuaj pleev ib ce nyiam hemispherical silica?
Yog vim li cas yog vim li cas hemispherical silica zoo dua spherical silica yog tias nws tsis tsuas yog muaj lub hauv paus smoothness thiab moisturizing kev nkag siab ntawm silica hmoov, tab sis kuj coj tus thiab kev sib tw silky kov rau ntawm daim tawv nqaij, ntxiv dag zog rau cov mos mos cov nyhuv, visually txhim kho daim tawv nqaij wrinkles, txhim kho. xim saturation, thiab nws cov hemispherical thiab sunken zoo tuaj yeem tuav ntawm daim tawv nqaij zoo dua. Nws zoo heev txhim kho cov nyhuv ntev ntawm cov khoom pleev, tshwj xeeb tshaj yog cov khoom siv hmoov. Hemispherical silica yog cov tawv nqaij ntau dua.
Piv txwv li, thaum spherical silica thiab hemispherical silica feem ntau siv rau hauv daim di ncauj, vim hais tias cov hmoov kheej kheej yog ib qho yooj yim rau yob ntawm daim tawv nqaij, nws yuav ua rau mica thiab pigment dov rov qab nrog nws, thiab xim ceev yuav ua rau qaug zog; Cov hmoov hemispherical nyob twj ywm thiab inlay rau ntawm daim tawv nqaij, yog li cov mica thiab pigment tsis swb, thiab qhov concentration no yuav ua rau cov xim ntau concentrated. Yog li ntawd, nyob rau hauv tib txoj kev siv rau sab hauv ntawm tib neeg forearm, di ncauj balm uas muaj hemispherical silica muaj ntau dua xim saturation thiab zoo dua durability.

Hauv thaj tsam ntawm cov tshuaj pleev thaiv hnub, hemispherical silica kuj tau cog lus. Ua ntej tshaj plaws, silica nws tus kheej yog ib qho tseem ceeb hauv cov tshuaj pleev thaiv hnub, tshwj xeeb tshaj yog cov tshuaj pleev thaiv hnub lub cev. Cov tshuaj pleev thaiv hnub lub cev muaj kev nyab xeeb, qhov laj thawj tseem ceeb yog cov hmoov uas nws muaj (titanium dioxide, zinc oxide, thiab lwm yam) yog inert, yuav tsis photodegraded, thiab tsis muaj teeb meem ntawm daim tawv nqaij, tab sis qhov tsis zoo kuj pom tseeb, tshuaj pleev thaiv hnub. yog ib qho yooj yim rau agglomerate thiab tso nyiaj. Lub luag haujlwm ntawm silicon dioxide yog tsim los tiv thaiv qhov chaw peb sab ntawm qhov chaw ntawm titanium dioxide thiab zinc oxide, ua rau tsis muaj zog ntawm kev nyiam ntawm cov khoom, txo qhov muaj peev xwm ntawm agglomeration, ua kom lub cev zoo dua qub thiab ruaj khov dua, thiab muab kev ua tau zoo thixotropic ntxiv, uas tuaj yeem pab cov khoom sib kis sib npaug ntawm daim tawv nqaij, txhim kho daim tawv nqaij thiab hnov thaum thov.
Txawm li cas los xij, yog tias siv hemispherical silica, cov tshuaj pleev thaiv hnub tuaj yeem txhim kho ntxiv. Qhov no yog vim hais tias cov hemispherical silica muaj cov yam ntxwv ntawm kev cuam tshuam ntawm kev cuam tshuam ntawm ultraviolet rays, yog li ntawd lub ultraviolet rays txais los ntawm ultraviolet absorber muaj ntau dua, thiab tib lub sij hawm, ultraviolet rays reflected los ntawm ultraviolet rays tawg yog ntau, uas indirectly txhim kho. cov tshuaj tiv thaiv tshav ntuj thiab tuaj yeem ua tiav cov txiaj ntsig ntawm kev ua kom pom tseeb.
Tag nrho cov nyob rau hauv tag nrho, kev muag khoom ntawm cov tshuaj pleev ib ce tau nce zuj zus nyob rau hauv xyoo tas los no, thiab qhov kev thov rau silica kuj tseem nce xyoo los ntawm xyoo. Nyob rau hauv cov xwm txheej zoo li no, cov txiaj ntsig zoo ntawm hemispherical silica yuav tsum ua lub luag haujlwm tseem ceeb, yog li kuv ntseeg tias nws yuav muaj kev cia siab rau daim ntawv thov zoo hauv kev lag luam tshuaj pleev ib ce.
