Kufufuza ndi kakulidwe ka mankhwalawa kumatengera gel osakaniza a buluu osintha mtundu wa silika, womwe ndi gelisi yosintha mtundu wa lalanje yomwe imapezedwa ndikuyika gel osakaniza a silika wosakaniza ndi mchere wosakanikirana. kuwononga chilengedwe. Zogulitsazo zakhala m'badwo watsopano wazinthu zokomera chilengedwe ndi mikhalidwe yake yoyambirira yaukadaulo komanso magwiridwe antchito abwino a adsorption.
Izi zimagwiritsidwa ntchito makamaka pa desiccant ndikuwonetsa kuchuluka kwa machulukitsidwe a desiccant ndi chinyezi chachifupi cha ma CD osindikizidwa, zida zolondola ndi mamita, ndi umboni wa chinyezi wa ma CD ndi zida.
Kuphatikiza pa zinthu za guluu wa buluu, guluu wa lalanje alinso ndi zabwino zopanda cobalt chloride, zopanda poizoni komanso zopanda vuto. Pogwiritsidwa ntchito palimodzi, amagwiritsidwa ntchito kusonyeza kuchuluka kwa chinyezi cha desiccant, kuti adziwe chinyezi cha chilengedwe. Amagwiritsidwa ntchito kwambiri mu zida zolondola, mankhwala, petrochemical, chakudya, zovala, zikopa, zida zapanyumba ndi mpweya wina wamakampani.
