Ma Desiccants amatenga gawo lofunikira pakusunga mtundu wazinthu komanso kukhazikika mwa kuyamwa chinyezi komanso kuthana ndi zinthu monga dzimbiri, nkhungu, ndi kuwonongeka komwe kumachitika chifukwa cha chinyezi. M'nkhaniyi, tidzayang'anitsitsa ma desiccants awiri otchuka - aluminium activated ndi silika gel, kufufuza makhalidwe awo apadera, ubwino, ndi zolephera.
Aluminium activated ndi mtundu waporous kwambiri wa aluminium oxide womwe umadziwika chifukwa cha mawonekedwe ake apadera a adsorption. Amagwiritsidwa ntchito kwambiri m'mafakitale owumitsa ntchito chifukwa cha kuthekera kwake kuchotsa chinyezi kuchokera mumlengalenga ndi mpweya. Malo ake akuluakulu ndi porosity yapamwamba imapangitsa kuti ikhale desiccant yothandiza kusunga khalidwe lazinthu zodziwika bwino monga mankhwala, zamagetsi, ndi mankhwala. Komabe, chimodzi mwazoletsa za aluminiyamu yoyendetsedwa ndikuti imatha kutulutsa kutentha kwakukulu panthawi ya adsorption, zomwe sizingakhale zoyenera kugwiritsa ntchito zina.
Kumbali ina, silika gel ndi desiccant synthetic yomwe imapangidwa kuchokera ku silicon dioxide. Amadziwika chifukwa cha malo ake okwera komanso kuyanjana kwakukulu kwa mamolekyu amadzi, zomwe zimapangitsa kuti adsorbent yabwino ya chinyezi. Geli ya silika imapezeka kawirikawiri m'mapaketi mkati mwazopaka kuti zinthu zizikhala zowuma komanso zosawonongeka ndi chinyezi. Amagwiritsidwanso ntchito kuteteza zipangizo zamagetsi, makamera, ndi katundu wachikopa panthawi yosungira ndi kuyendetsa. Ngakhale kuti gel osakaniza a silica ali ndi mphamvu zochepa zokopa ndipo angafunikire kusinthidwa kapena kusinthidwa kawirikawiri.
Onse aluminiyamu ndi silika gel osakaniza ali ndi mphamvu ndi zofooka zawo pankhani ya chinyezi adsorption. Ngakhale aluminiyamu yoyatsidwa ndiyoyenera kuyanika m'mafakitale komanso kugwiritsa ntchito kwakukulu, gelisi ya silica ndiyoyenera pazinthu zazing'ono, zosalimba. Kumvetsetsa mikhalidwe yosiyana ya ma desiccants awa ndikofunikira pakusankha yoyenera pazinthu zina zokhudzana ndi chinyezi.
Kuwonjezera pa makhalidwe awo osiyana, onse a desiccants ali ndi njira zosiyana zowonetsera chinyezi. Alumina yoyendetsedwa imagwira ntchito kudzera munjira yotchedwa physisorption, pomwe mamolekyu amadzi amalowetsedwa pamwamba pa desiccant. Kumbali ina, gelisi ya silika imagwiritsa ntchito kuphatikiza kwa kutsatsa kwakuthupi ndi kukhazikika kwa capillary kuti itseke chinyezi mkati mwa ma pores ake. Kumvetsetsa njirazi ndikofunikira pakuwongolera magwiridwe antchito a desiccants muzogwiritsa ntchito zosiyanasiyana.
Kuphatikiza apo, ma desiccants awa amapeza ntchito zambiri m'mafakitale osiyanasiyana. Aluminiyamu adamulowetsa ntchito kwambiri kuyanika mpweya wothinikizidwa ndi mpweya, komanso kuyeretsa zakumwa monga propane ndi butane. Amagwiritsidwanso ntchito poyanika zosungunulira komanso kuchotsa zinyalala za gasi. Komano, silika gel osakaniza amagwiritsidwa ntchito poteteza zida zamagetsi zovutirapo, kupewa dzimbiri ndi dzimbiri mumfuti, komanso kusunga zolemba ndi zojambulajambula zamtengo wapatali.
Pomaliza, onse opangidwa ndi alumina ndi silika gel desiccants amatenga gawo lofunikira pakusunga mtundu wazinthu komanso kukhazikika pothana ndi zovuta zokhudzana ndi chinyezi. Desiccant iliyonse ili ndi mawonekedwe akeake, zopindulitsa, ndi zoperewera, zomwe zimawapangitsa kukhala oyenera ntchito zosiyanasiyana. Kumvetsetsa mapangidwe, njira zowonetsera chinyezi, komanso kugwiritsa ntchito ma desiccants awa ndikofunikira kuti muzigwiritsa ntchito bwino m'mafakitale osiyanasiyana. Kaya ndikuwumitsa kwa mafakitale kapena kuteteza zamagetsi, desiccant yoyenera ikhoza kupanga kusiyana kwakukulu pakusunga umphumphu wa mankhwala ndi khalidwe.
