Muaj ntau ntau hom desiccants muaj uas feem ntau siv los tiv thaiv kev puas tsuaj rau ntau yam kev siv. Ntawm no yog 6 lub npe nrov desiccant siv dav rau kev tswj dej noo:
Silica Gel: Silica gel yog ib qho ntawm feem ntau siv desiccants. Nws yog tsim los ntawm silicon dioxide thiab muaj peev xwm nqus dej noo. Silica gel tuaj yeem pom hauv cov pob ntawv me me, cov hnab ntim khoom, lossis cov hlaws xoob xoob thiab feem ntau siv hauv cov khoom siv hluav taws xob, tshuaj, thiab ntim khoom noj.
Clay Desiccants: Av nplaum desiccants, xws li bentonite av nplaum, yog cov khoom siv ntuj tsim nrog zoo heev noo noo-absorbing zog. Lawv muaj kev nyab xeeb, tsis muaj tshuaj lom, thiab ib puag ncig tus phooj ywg. Av nplaum desiccants feem ntau siv hauv ntim khoom siv hluav taws xob, khoom siv tawv, thiab lwm yam khoom uas tswj cov dej noo tseem ceeb.
Molecular Sieve: Molecular sieve desiccants muaj cov khoom siv hluavtaws zeolite nrog cov pores zoo uas xaiv cov dej noo molecules. Lawv muaj peev xwm nqus dej noo siab thiab feem ntau siv hauv cov khoom siv hluav taws xob, tshuaj, thiab cov roj ntsha ntuj.
Calcium Chloride: Calcium chloride desiccants muaj peev xwm nqus dej noo thiab feem ntau muaj xws li pellets lossis hauv daim ntawv granular. Lawv muaj txiaj ntsig zoo ntawm kev nqus dej noo los ntawm huab cua thiab feem ntau siv hauv kev thauj mus los, khaws cia, thiab kev siv hauv kev lag luam.
Montmorillonite Clay - Feem ntau hu ua bentonite yog ib txwm tshwm sim adsorbent tsim los ntawm kev tswj kom qhuav ntawm magnesium aluminium silicate ntawm sub-bentonite hom. Av nplaum desiccant ua haujlwm zoo tshaj 120 degree F; txhua yam saum toj no 120 degree F cov av nplaum tuaj yeem muab cov dej noo. Montmorillonite av nplaum yog qhov tsawg tshaj plaws desiccant ib phaus thaum piv nrog rau lwm tus thiab yog dav siv hauv tshuaj thiab tshuaj.
Nitrogen (N2) - Tsis zoo li lwm hom desiccant, Nitrogen yog roj. Ib qho txiaj ntsig ntawm Nitrogen yog thaum siv hauv cov khoom siv nitrogen-base qhuav, txheeb ze Humidity (RH) tuaj yeem txo qis hauv chamber. Feem ntau siv nyob rau hauv semiconductor kev tshawb fawb thiab kev lag luam kev lag luam kom meej tswj RH thaum khaws cia. Ib lub 'meter' tuaj yeem pab saib xyuas thiab kho kom tswj tau qhov kev xav tau teeb tsa. Nitrogen tuaj yeem yuav hauv cov tso tsheb hlau luam lossis lub tshuab hluav taws xob nitrogen tuaj yeem siv los tsim cov nitrogen hauv chav kuaj.
Thaum xaiv tus desiccant, nws yog ib qho tseem ceeb uas yuav tau xav txog yam xws li cov dej noo, qhov kub thiab txias, thiab cov kev cai tshwj xeeb ntawm koj daim ntawv thov. Txhua hom desiccant muaj nws tus kheej lub zog thiab cov kev txwv, yog li nws yog ib qho tsim nyog los sab laj cov khoom tshwj xeeb thiab cov txheej txheem los txiav txim siab qhov tsim nyog desiccant rau koj cov kev xav tau tshwj xeeb.
