Iidesiccants zidlala indima ebalulekileyo ekugcineni umgangatho kunye nozinzo lwemveliso ngokufunxa umswakama kunye nokulwa nemiba efana nokugqwala, ukungunda, kunye nokuwohloka okubangelwa kukufuma. Kweli nqaku, siza kujonga ngokusondeleyo iidesiccants ezimbini ezidumileyo - i-alumina esebenzayo kunye ne-silica gel, sihlola iimpawu zazo ezizodwa, iingenelo kunye nemida.
I-alumina esebenzayo luhlobo lwe-aluminium oxide enemingxuma emininzi eyaziwa ngeempawu zayo ezibalaseleyo zokufunxa. Isetyenziswa kakhulu kwizicelo zokomisa kwimizi-mveliso ngenxa yokukwazi kwayo ukususa umswakama emoyeni nakwiigesi. Ummandla wayo omkhulu kunye nokufunxa okuphezulu kwenza ukuba ibe yi-desiccant esebenzayo yokugcina umgangatho weemveliso ezinobuthathaka ezifana namayeza, izixhobo ze-elektroniki kunye neekhemikhali. Nangona kunjalo, enye yemida ye-alumina esebenzayo kukuba inokukhupha ubushushu obuninzi ngexesha lenkqubo yokufunxa, okusenokungafaneleki kwezinye izicelo.
Kwelinye icala, i-silica gel yi-desiccant yokwenziwa eyenziwe nge-silicon dioxide. Yaziwa ngomphezulu wayo ophezulu kunye nokuqina kwayo kwiimolekyuli zamanzi, okwenza ukuba ibe yi-moisture absorbent esebenzayo. I-silica gel ifumaneka rhoqo kwiipakethi ezingaphakathi kwiphakheji yemveliso ukugcina iimpahla zomile kwaye zingonakaliswanga kumswakama. Ikwasetyenziselwa ukukhusela izixhobo ze-elektroniki, iikhamera, kunye neempahla zesikhumba ngexesha lokugcina nokuthuthwa. Nangona isebenza kakuhle, i-silica gel inomthamo omncinci wokufunxa kwaye inokufuna ukutshintshwa okanye ukuhlaziywa rhoqo.
Zombini i-alumina esebenzayo kunye ne-silica gel zinamandla kunye nobuthathaka bazo xa kufikwa ekufakweni komswakama. Nangona i-alumina esebenzayo ifanelekile ngakumbi ekomiseni kwimizi-mveliso kunye nokusetyenziswa okukhulu, i-silica gel ifanelekile ngakumbi kwiimveliso ezincinci nezithambileyo. Ukuqonda iimpawu ezahlukeneyo zezi desiccants kubalulekile ekukhetheni efanelekileyo kwimiba ethile enxulumene nomswakama.
Ukongeza kwiimpawu zazo ezahlukileyo, zombini ezi desiccants zineendlela ezahlukeneyo zokufunxa umswakama. I-alumina esebenzayo isebenza ngenkqubo eyaziwa ngokuba yi-physisorption, apho iimolekyuli zamanzi zifunxa ngokwasemzimbeni kumphezulu we desiccant. Kwelinye icala, ijeli ye-silica isebenzisa indibaniselwano yokufunxa ngokwasemzimbeni kunye nokufunxa kwe-capillary ukubamba umswakama ngaphakathi kwee-pores zayo. Ukuqonda ezi ndlela kubalulekile ekwenzeni ngcono ukusebenza kwee desiccants kwizicelo ezahlukeneyo.
Ngaphezu koko, ezi desiccants zisetyenziswa kakhulu kumashishini ahlukeneyo. I-alumina esebenzayo isetyenziswa kakhulu ekomiseni umoya ocinezelweyo kunye neegesi, kunye nokucoca ulwelo olufana nepropane kunye ne-butane. Ikwasetyenziswa ekomiseni izinyibilikisi kunye nokususa ukungcola kwigesi yendalo. Kwelinye icala, i-silica gel isetyenziswa kakhulu ekukhuseleni izixhobo ze-elektroniki ezinobuthathaka, ukuthintela umhlwa kunye nokugqwala kwizibhamu, kunye nokugcina amaxwebhu axabisekileyo kunye nemifanekiso yobugcisa.
Ukuqukumbela, zombini ii-desiccants ze-alumina ezisebenzayo kunye ne-silica gel zidlala indima ebalulekileyo ekugcineni umgangatho kunye nozinzo lwemveliso ngokulwa nemiba enxulumene nokufuma. I-desiccant nganye ineempawu zayo ezizodwa, iingenelo, kunye nemida, nto leyo eyenza ukuba zifaneleke kwiindlela ezahlukeneyo zokusetyenziswa. Ukuqonda izakhiwo, iindlela zokufunxwa komswakama, kunye nokusetyenziswa kwezi desiccants kubalulekile ekuzisebenziseni ngokufanelekileyo kumashishini ahlukeneyo. Nokuba kukomiswa kwemizi-mveliso okanye ukukhusela izixhobo ze-elektroniki, i-desiccant efanelekileyo inokwenza umahluko omkhulu ekugcineni umgangatho kunye nomgangatho wemveliso.
