Desiccants tuaj yeem muab faib ua cov acidic, alkaline thiab nruab nrab thiab nruab nrab desiccants raws li lawv cov tshuaj lom neeg.
Acidic Desiccants: Hom desiccants feem ntau haum rau kom qhuav acidic cov ntaub ntawv. Cov Acidic desiccants muaj xws li phosphorus pentoxide, anhydrous calcium chloride thiab muaj cov sulfuric acid. Phosphorus pentoxide muaj lub cev qhuav dej muaj zog thiab haum rau ziab cov tshuaj tiv thaiv xws li cov neeg tsim kho, hydrocarbons, thiab halogenated alkanes; Kev haus dej tsis muaj zog calhium muaj cov peev xwm nqus dej muaj zog, tab sis tsis haum rau ziab cov cawv, amines, thiab lwm yam; Hnov cov leeg sulfuric acid feem ntau yog siv rau cov roj kom qhuav xws li cov roj av thiab hydrogen chloride, tab sis yog corrosive heev.
Alkaline Desiccants: Tsim nyog rau kev ziab cov ntaub ntawv alkaline. Cov tshuaj lom alkaline xws li cov potoxsium hydrodium hydroxide, anhydrous poov tshuaj carbonate thiab calcium oxide. Cov tshuaj no muaj cov tshuaj lom tau zoo thiab feem ntau siv los ua cov organic alkaline cov tshuaj reagents, tab sis lawv txoj kev txhim kho thiab ua rau lawv tau siv.
Desiccants Desiccants: Nws muaj ntau yam kev siv thiab kev nyab xeeb siab. Cov Desices Desiccott ib txwm muaj xws li anhydole sodium sulfate thiab anhydrous magnesium sulfate. Anhydrous sodium sulfate nqus dej ntau, tab sis cov txiaj ntsig kev nqus dej yog qeeb; Anhydrous magnesium sulfate nqus dej sai sai thiab ua tau zoo, thiab haum rau ziab dichloromomiatias.
Tsis tas li ntawd, cov neeg txom nyem tuaj yeem muab faib ua ob pawg raws li lawv cov qauv adsorption: kev kos duab lub cev thiab tshuaj kos duab. Lub cev adsorption desiccants xws li Silica gel, alumina gel, molecular sieves, thiab lwm yam, adsorb dej molecules los ntawm lub cev; Tshuaj lom adsorption desiccants muaj cov acidic, alkaline thiab nruab nrab thiab nqus dej los ntawm kev siv tshuaj lom neeg.
