Dawb soot
Silica yog ib qho ntxhia tshwm sim uas tshwm sim hauv pob zeb thiab av, ua ib feem tseem ceeb ntawm lub ntiaj teb crust. Nws cov khoom tshwj xeeb ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv ntau yam txheej txheem thiab kev siv, suav nrog huab cua huab cua thiab kev tsom xam.

Daim ntawv thov
Ib qho tseem ceeb ntawm kev siv huab cua silica yog ua ib qho desiccant. Qhov no txhais tau hais tias nws yog siv los nqus dej noo thiab tiv thaiv condensation ntawm cov cuab yeej xws li huab cua sensors, koob yees duab thiab lo ntsiab muag. Silica feem ntau muab tso rau hauv cov hnab me me thiab muab tso rau hauv cov khoom siv kom nws qhuav thiab tiv thaiv corrosion.
Lwm qhov tseem ceeb ntawm kev siv huab cua silica yog ua ib feem ntawm iav siv hauv cov cuab yeej ntsuas huab cua. Ntxiv silica rau iav pab txhim kho nws cov thermal thiab hluav taws xob, ua rau nws tiv taus qhov kub thiab txias thiab cuam tshuam hluav taws xob. Qhov no ua rau nws yog ib qho tseem ceeb ntawm cov cuab yeej xws li barometers, thermometers thiab anemometers, uas tso siab rau kev ntsuas qhov tseeb thiab meej ntawm huab cua.
