Silicone qhia
Silica gel yog qhov nyuaj, amorphous saw-zoo li thiab network zoo li silicic acid polymer particle nrog cov qauv tshuaj molecular ntawm SiO2.nH2O, uas yog hydrophilic polar adsorbent. Nws yog cov tshuaj tov dej ntawm sodium silicate kho nrog sulfuric acid los ua ib lub gel, uas tau ntxuav nrog dej kom tshem tawm sodium sulfate thiab qhuav kom tau ib khob iav silica gel uas yog siv rau kev ziab, roj sib tov thiab sib cais ntawm cov roj av. Kev siv tshuab silica gel tau muab faib ua ob hom: ntxhib pores thiab pores zoo. Lub ntxooj pore silica gel tuaj yeem nqus tau ntau dua 80% ntawm qhov hnyav ntawm adsorbent nyob rau hauv qhov xwm txheej ntawm txheeb ze av noo noo, thiab nyob rau hauv qis huab cua puag, cov adsorption ntau npaum li qis dua li ntawm qhov zoo pore silica gel.
