Feem ntau cov ntawv qhia cov av noo yog tsim los pab txhawb cov xim thim rov qab- hloov ua haujlwm. Lub hauv paus ntsiab lus tseem ceeb yog ua raws li kev siv cobalt- muaj cov khoom sib txuas (xws li cobalt chloride) lossis lwm yam av noo- cov ntaub ntawv rhiab heev, uas hloov xim nyob rau hauv qhov sib txawv ntawm cov av noo ib puag ncig. Thaum ambient humidity nce, qhov taw qhia hloov ntawm xiav mus rau liab; Thaum cov av nyob ib puag ncig txo qis, cov xim maj mam rov qab mus rau xiav, yog li ua kom rov siv dua. Cov txheej txheem no tuaj yeem ua kom nrawm nrawm los ntawm kev ziab kom qhuav lossis ci ci, xws li ci ntawm 100℃~ 110℃rau 3 ~ 6 feeb mus rau ob peb teev, rov ua dua daim npav rau nws thawj lub xeev.
Cov xwm txheej thiab kev ceev faj rau kev rov siv dua:
Reversible xim-hloov mechanism: Cov xim hloov ntawm cov ntawv qhia cov av noo yog raws li cov tshuaj hydration tshuaj, ib qho txheej txheem rov qab ntawm lub cev. Ntev npaum li daim npav tsis tau tshaj nws lub neej kev pabcuam lossis tsis muaj paug, cov xim tuaj yeem hloov pauv ntawm qhov chaw ntub thiab qhuav.
Tsis txhob cuam tshuam ntau dhau: Yog tias daim npav raug cov av noo nyob rau lub sijhawm ntev lossis siv ntau zaus, nws yuav ua rau cov khoom qaug zog, txo cov xim rov qab muaj peev xwm, thiab thaum kawg poob qhov raug. Nws yog feem ntau pom zoo kom txwv tus naj npawb ntawm kev siv nyob rau hauv ib tug tsim nyog ntau yam los xyuas kom meej kev nyeem ntawv txhim khu kev qha.
Recycling kom raug: Daim npav tsis muaj xim tuaj yeem rov qab los ntawm kev ziab: Muab tso rau hauv qhov cub ntawm 110℃rau kwv yees li 3 teev, tom qab ntawd txias ua ntej siv.
Ua ntej rov ua dua tshiab, xyuas kom daim npav tsis muaj kab mob thiab tsis txhob ntxuav qhov taw qhia nrog dej.
Yuav tsum tau khaws cia nruj me ntsis: Daim npav tsis siv yuav tsum muab ntim rau hauv cov ntim khoom qub nrog lub tshuab desiccant. Hloov cov desiccant tom qab txhua 3 qhov qhib.
Kev khaws cia yuav tsum nyob hauv qhov chaw qhuav, txias, tsis txhob tshav ntuj ncaj qha thiab kub thiab av noo.
Distinguishing ntawm Reversible thiab Irreversible Hom: Txawm hais tias feem ntau ib txwm humidity cards yog reversible, irreversible humidity indicators, As (xws li Clariant Humitector™ Type 2) muaj nyob rau hauv lub lag luam. Cov no yog siv los sau seb cov khoom puas tau raug cuam tshuam rau qhov chaw txaus ntshai tshaj 60% RH.
