Dab tsi yog Kev Siv CovSilica hauv Kev Kho Hniav?
Silica, tseem hu ua silicon dioxide, yog ib qho ntxhia uas pom muaj nyob hauv qhov xwm txheej. Nws yog siv nyob rau hauv ntau lub lag luam, nrog rau kev kho hniav. Silica muaj ntau yam siv hauv kev lag luam kho hniav vim nws ntau yam khoom.
Ib qho tseem ceeb ntawm kev siv silica hauv kev kho hniav yog ua cov tshuaj txhuam hniav hauv cov tshuaj txhuam hniav thiab tshuaj ntxuav hniav dawb. Silica yog ib qho zoo abrasive vim tias nws yog ib qho nyuaj thiab muaj cov npoo ntse uas tuaj yeem tshem tawm cov stains thiab cov quav hniav los ntawm cov hniav. Nws kuj yog siv los ua ib qho abrasive hauv prophy pastes los txhuam hniav thaum ntxuav hniav.
Silica kuj tseem siv rau hauv cov ntaub ntawv kho hniav ua tus muab tub lim lossis tus neeg sawv cev txhawb nqa. Qhov no suav nrog cov khoom sib xyaw, iav ionomer cements, thiab cov hniav ceramics. Silica pab txhim kho lub zog thiab hnav tsis kam ntawm cov ntaub ntawv no, nrog rau lawv cov khoom tuav thiab kev zoo nkauj.
Lwm qhov kev siv silica hauv kev kho hniav yog nyob rau hauv kev tsim cov hniav cog hniav. Silica yog siv los ua kev kho mob saum npoo los ua kom cov biocompatibility ntawm cov cog cog thiab txhim kho nws cov kev sib raug zoo nrog cov pob txha nyob ib puag ncig. Nws kuj yog siv los ua cov txheej hauv kev cog qoob loo los txhim kho lawv cov hnav tsis kam thiab txo qhov kev pheej hmoo ntawm cov kab mob colonization.
Silica kuj tseem siv rau hauv kev tsim cov hniav prostheses, xws li cov hniav hniav thiab ib feem. Nws yog siv los ua ib qho muab tub lim rau hauv cov ntaub ntawv kho hniav kom txhim kho lawv lub zog thiab kav ntev. Silica kuj tseem siv rau hauv kev tsim cov hniav nyiaj hniav kub los txhim kho lawv qhov zoo nkauj thiab hnav tsis kam.
Zuag qhia tag nrho, silica plays lub luag haujlwm tseem ceeb hauv kev kho hniav vim nws cov khoom tshwj xeeb thiab muaj txiaj ntsig zoo hauv ntau yam ntawm kev kho hniav. Txawm hais tias nws yog siv los ua ib qho abrasive, muab tub lim, tus neeg saib xyuas kev txhawb zog lossis kev kho saum npoo, silica pab txhim kho kev ua tau zoo thiab kev ua haujlwm ntev ntawm kev kho hniav.
