Typedị 4a denticcant bụ akwara miecular na-eme ka ọ dị mma. Ihe bụ isi ihe bụ aluminosilidililidililidilililidilililidilililidilililidililidilililili. Ogo pore ya na-agafeghị oke ma dịkwa mma maka mosocbing mmiri molecules na obere ụmụ irighiri ihe. Nke a bụ ụfọdụ ngwa ndị bụ isi nke klaasị 4a desticcants:
1. Mwepu ikuku nke gas: N'oge nhazi na nchekwa nke gas gas, ojiji nke klas 4a desticcans nwere ike wepu mmiri site na gas n'okike ma meziwanye ịdị ọcha ya na arụmọrụ ya.
Ihe ngosi nke Ithanol na-emepụta ihe: Na usoro nke ethanol na distillation, enwere ike iji klaasị 4a graccant wepụ mmiri na ịdị mma nke ethanol.
Ihe dị ọcha: A ga-eji planiar dị ka ihe dị ka ikuku ikuku na-ama jijiji na mmiri na iru mmiri na ikuku, melite mma ikuku, ma na-abawanye nkasi obi nke ime ụlọ ime ụlọ.
4ndusts gas gas: eji wepu mmiri na adighi nma na ikuku nke gas, dika nitrogen, oxygen, wdg.
Enwere ike iji ụlọ ọrụ kemịkalụ 5.
6.Ghipụta nke lubricating mmanụ: N'oge nrụpụta ma jiri mmanụ lubcating nwere ike wepu mmiri site na mmanu lubring nwere ike wepu mmiri na arụmọrụ nke lubricating mmanụ.
Actinecking ngwugwu: Na nkwakọ ngwaahịa nri, enwere ike iji akwụkwọ nri 4a iji nweta mmiri n'ime nkwakọba, na-eme ka ọ dị ọcha na ogo nri.
Industrylọ ọrụ na-emepụta ọgwụ: Na ọgwụ na-emepụta ọgwụ, enwere ike iji klaasị ọgwụ dị ka onye na-ede ọgwụ maka ọgwụ iji wepu ọgwụ na ọgwụ ma hụ na nkwụsi ike na ogo nke ọgwụ.
Nchịkọta, Klas dị iche iche nwere ọtụtụ ngwa ma na-arụ ọrụ dị mkpa iji wepụ mmiri ma melite ogo nke gas, mmiri mmiri na siri ike. Ngwaahịa anyị bụ: Insuliting iko na-atọ ụtọ, akwara na-atọgbọrọ n'efu, mkpọkọta, nkwakọ ngwaahịa despiccant, ịnweta mkpụrụ osisi molecular na-agbachi obi.
