Ama-Desiccants adlala indima ebalulekile ekugcineni izinga lomkhiqizo nokuzinza ngokumunca umswakama futhi alwe nezinkinga ezinjengokugqwala, isikhunta, nokuwohloka okubangelwa umswakama. Kulesi sihloko, sizobheka ngokucophelela ama-desiccants amabili athandwayo - i-alumina ecushiwe ne-silica gel, sihlola izici zabo eziyingqayizivele, izinzuzo, kanye nemikhawulo.
I-alumina ecushiwe iwuhlobo olunezimbobo kakhulu lwe-aluminium oxide elaziwa ngezici zalo eziyingqayizivele zokukhangisa. Isetshenziswa kabanzi ekusetshenzisweni kokumisa izimboni ngenxa yekhono layo lokususa umswakama emoyeni namagesi. Indawo yayo enkulu kanye ne-porosity ephezulu yenza kube i-desiccant ephumelelayo yokugcina ikhwalithi yemikhiqizo ebucayi efana nemithi, i-electronics, namakhemikhali. Kodwa-ke, omunye wemikhawulo ye-alumina ecushiwe ukuthi ingakhulula inani elibalulekile lokushisa phakathi nenqubo ye-adsorption, okungenzeka ingafaneleki kwezinye izinhlelo zokusebenza.
Ngakolunye uhlangothi, i-silica gel iyi-synthetic desiccant eyenziwe nge-silicon dioxide. Iyaziwa ngendawo yayo ephezulu kanye nokuhlangana okuqinile kwama-molecule amanzi, okuyenza ibe i-adsorbent yomswakama ephumelelayo. Ijeli ye-silica ivamise ukutholakala emaphaketheni ngaphakathi emaphaketheni omkhiqizo ukuze kugcinwe izimpahla zomile futhi zingenawo umonakalo womswakama. Iphinde isetshenziselwe ukuvikela izinto zikagesi, amakhamera, nezimpahla zesikhumba ngesikhathi sokugcinwa nokuhamba. Naphezu kokusebenza kwayo, ijeli ye-silica inomthamo olinganiselwe wokukhangisa futhi ingase idinge ukushintshwa noma ukukhiqizwa kabusha njalo.
Kokubili ijeli ye-alumina ne-silica ecushiwe inamandla nobuthakathaka bazo uma kuziwa ekukhangisweni komswakama. Ngenkathi i-alumina ecushiwe ifaneleka kakhulu ukomiswa kwezimboni kanye nezinhlelo zokusebenza ezinkulu, ijeli ye-silica ifaneleka kangcono imikhiqizo emincane, entekenteke kakhulu. Ukuqonda izici ezihlukile zalawa ma-desiccants kubalulekile ekukhetheni okulungile ezindabeni ezithile ezihlobene nomswakama.
Ngaphezu kwezici zabo ezihlukile, ama-desiccants womabili anezindlela ezihlukene zokukhangisa umswakama. I-alumina ecushiwe isebenza ngenqubo eyaziwa ngokuthi i-physisorption, lapho ama-molecule amanzi akhangiswe ngokoqobo ebusweni be-desiccant. Ngakolunye uhlangothi, ijeli ye-silica isebenzisa inhlanganisela ye-adsorption ebonakalayo kanye ne-capillary condensation ukuze ibambe umswakama ngaphakathi kwezimbotshana zayo. Ukuqonda lezi zindlela kubalulekile ukuze kuthuthukiswe ukusebenza kwama-desiccant ezinhlelweni ezahlukene.
Ngaphezu kwalokho, lawa ma-desiccant athola ukusetshenziswa okubanzi ezimbonini ezahlukahlukene. I-alumina ecushiwe isetshenziswa kakhulu ekomisweni komoya ocindezelwe namagesi, kanye nasekuhlanzweni koketshezi olufana ne-propane ne-butane. Ibuye isetshenziselwe ukomiswa kwezincibilikisi nasekukhipheni ukungcola egesini yemvelo. Ngakolunye uhlangothi, ijeli ye-silica, ivame ukusetshenziselwa ukuvikela izinto zikagesi ezibucayi, ukuvimbela ukugqwala nokugqwala kwezibhamu, nokugcina imibhalo ebalulekile nemisebenzi yobuciko.
Sengiphetha, kokubili i-alumina ecushiwe kanye ne-silica gel desiccants idlala indima ebalulekile ekugcineni ikhwalithi yomkhiqizo nokuzinza ngokubala izinkinga ezihlobene nomswakama. I-desiccant ngayinye inezici zayo ezihlukile, izinzuzo, kanye nemikhawulo, okwenza zilungele izinhlelo zokusebenza ezahlukene. Ukuqonda izakhiwo, izindlela zokukhangisa umswakama, kanye nokusetshenziswa kwalawa ma-desiccants kubalulekile ukuze usetshenziswe ngokuphumelelayo ezimbonini ezihlukahlukene. Kungakhathaliseki ukuthi i-industrial drying noma i-electronics evikelayo, i-desiccant efanele ingenza umehluko omkhulu ekugcineni ubuqotho bomkhiqizo kanye nekhwalithi.
