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 nokulinganiselwa.
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 nasekusetshenzisweni kwezinga elikhulu, ijeli ye-silica ifaneleka kangcono imikhiqizo emincane, ethambile.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 phezu kwe-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.
