Silica uas ua kom cov tshuaj txhuam hniav rau cov tshuaj txhuam hniav
Silicon Dioxide ua lub luag haujlwm tseem ceeb ua ib txoj kev txhuam hniav ntawm cov tshuaj txhuam hniav. Kev tswj hwm cov neeg sawv cev, suav nrog silicon dioxide, calcium carbonate, insoluble pyphate, thiab dicalcium podboncthate, thiab dicalcium phosphate, account rau 20% rau 60% ntawm cov tshuaj txhuam cov ntsiab lus. Lawv ua haujlwm los ntawm kev ua kom zoo nkauj thaum txhuam hniav los pab kev tu thiab txhuam cov hniav, tshem cov mos mos quav hniav, thiab qee qhov pigmentation.
Silicon Dioxide muaj cov tshuaj ruaj khov zoo thiab tsis muaj kev xav nrog lwm yam tshuaj, tsuas yog muaj zog alkalis. Nws yog sib luag thiab ua kom zoo sib xws nrog lwm cov khoom xyaw hauv cov tshuaj txhuam hniav, ua rau muaj kev ntxhib los mos ruaj khov thiab du. Lub Crystalline Daim Ntawv ntawm silicon dioxide feem ntau yog spherical honeycomb hais nrog me voids. Thaum cov khoom siv los sib cuag nrog cov hniav, lawv disperse, ua rau muaj kev nce hauv thaj chaw tiv tauj nrog cov hniav sib txawv, ua rau cov kev ntxuav hniav zoo. Tus txhuam tus nqi tuaj yeem hloov kho nyob rau qee yam, ua kom cov hniav tawv kom haum rau cov txha hniav laus.
Silicon Dioxide lub chaw ua haujlwm tsis raug cai kuj tseem tuaj yeem hloov kho nyob rau qee qhov, ua rau nws zoo meej rau kev ua tshuaj txhuam hniav. Nws yog qhov fluoride heev thiab tswj txoj kev ua kom cov tshuaj txhuam hniav zoo ntawm cov tshuaj txhuam hniav zoo. Ib qho ntxiv, nws cov roj nqus tus nqi tuaj yeem hloov kho nyob rau hauv ntau qhov ntau, ua rau nws tsis yog tsim nyog ua ib qho tuab. Nws yog qhov siab huv thiab muaj tsawg dua cov teeb meem tsis zoo, ua rau nws siv tshuaj txhuam hniav zoo.
Hauv kev xaus, silicon dioxide yog ib qho tseem ceeb ntawm cov tshuaj txhuam hniav uas yog ib qho kev txhuam tus neeg sawv cev. Thaum siv tau kom raug, nws txhim kho kev tu thiab ua polishing ntawm cov tshuaj txhuam hniav thiab muaj kev nyab xeeb thiab txuag tau zoo.
