Kev kho dehumidification ntawm huab cua suav nrog kev kho dehumidification hauv cov txheej txheem cua txias hauv chav dej tshuaj tsuag, thiab tshuaj dehumidification, uas yog, nqus dej noo hauv huab cua los ntawm kev siv tus neeg sawv cev hygroscopic. Muaj ob hom hygroscopic: khoom thiab kua. Cov khoom hygroscopic tuaj yeem muab faib ua ob hom: daim ntawv ntawm cov khoom hygroscopic tseem tsis hloov pauv tom qab nqus dej thiab daim ntawv ntawm cov khoom hygroscopic maj mam hloov mus rau cov kua dej tom qab nqus dej.
Cov khoom hygroscopic muaj xws li silica gel, activated alumina thiab lwm yam ntaub ntawv. Thaum lub peev xwm hygroscopic ploj lawm, cov dej nqus tau tuaj yeem raug tshem tawm los ntawm kev siv cua kub kom rov qab muaj peev xwm rov nqus tau.
Cov kua dej hygroscopic tuaj yeem txau rau hauv cov huab cua kho nrog cov kev daws teeb meem xws li potassium chloride, kom cov dej vapor siab ntawm cov kua qis dua qhov siab ntawm cov dej vapor nyob rau hauv cov huab cua kho, thiab cov dej tau hloov ntawm huab cua mus rau tus neeg sawv cev hygroscopic.
Cov khoom hygroscopic feem ntau yog cov khoom ntxeem tau, uas muaj cov nyhuv adsorption ntawm dej vapor.
Tshuaj dehumidification yog tsuas yog siv nyob rau hauv industrial cua txias tshuab yuav tsum tau tsawg humidity.
