Desiccant tuaj yeem faib ua peb pawg: acidic desiccant, alkaline desiccant thiab nruab nrab desiccant.
Acidic Desiccant: Hom desiccant no feem ntau haum rau kom qhuav acidic cov ntaub ntawv. Cov Acidic Desiccant muaj xws li phosphorus pentoxide, anhydrus calcium chloride thiab muaj cov sulfuric acid. Phosphorus pentoxide muaj lub zog ua kom muaj zog thiab feem ntau siv rau kev ziab cov neeg txawj ntse, hydrocarbons, halogenated alkanes, thiab lwm yam; AnhydreCium calcium muaj peev xwm nqus dej loj, tab sis tsis haum rau ziab cov cawv, amines, thiab lwm yam; Hnov cov sulfuric acid feem ntau siv rau kom qhuav hauv cov roj hauv av, thiab lwm yam, tab sis yog corrosive heev.
Alkaline Desiccant: Haum rau kom qhuav cov ntaub ntawv alkaline. Cov tshuaj lom alkaline xws li cov potoxsium hydrodium hydrothide, anhydrous poov tshuaj carbonate, calcium oxide thiab barium oxide. Cov desiccants no yog alkaline heev thiab hygroscopic thiab feem ntau siv rau kom qhuav organic alkaline cov tshuaj reagents. Txawm li cas los xij, barium oxide muaj qee yam toxicity thiab yuav tsum zam kom ntau li ntau tau hauv cov tshuaj.
Neutral desiccant: Hom desiccant no muaj ntau yam kev siv thiab muaj kev nyab xeeb. Cov Desices Desiccott ib txwm muaj xws li anhydole sodium sulfate thiab anhydrous magnesium sulfate. Anhydrous sodium sulfate nqus dej maj mam thiab yooj yim koog, tab sis nws yog pheej yig thiab feem ntau siv nyob rau hauv chaw soj nai; Anhydrous magnesium sulfate nqus dej sai sai thiab ua tau zoo, thiab haum rau ziab dichloromomiatias.
