Ijeli le-silica elibomvu
Lo mkhiqizo uyizinhlayiya ezimise okwesiyingi noma ezingajwayelekile. Ubonakala ubomvu onsomi noma obomvu onsomi kanye nomswakama. Ukwakheka kwawo okuyinhloko yi-silicon dioxide kanye nokushintsha kombala ngomswakama ohlukile. Ngaphandle kokusebenza okufana nokwesibhakabhakaijeli ye-silica, ayinayo i-cobalt chloride futhi ayinabo ubuthi, ayinangozi.

Ijeli ye-Alumino silica–AN
Ukubukeka kwe-aluminiumijeli ye-silicainombala ophuzi kancane noma omhlophe obonakalayo ngefomula yamakhemikhali yamamolekyuli mSiO2 • nAl2O3.xH2O. Izakhiwo zamakhemikhali ezizinzile. Ayishisi, ayincibiliki kunoma yisiphi isinyibilikisi ngaphandle kwesisekelo esiqinile kanye ne-hydrofluoric acid. Uma iqhathaniswa nejeli ye-silica encane enezimbobo, umthamo wokumunca womswakama ophansi uyafana (njenge-RH = 10%, RH = 20%), kodwa umthamo wokumunca womswakama ophezulu (njenge-RH = 80%, RH = 90%) uphakeme ngo-6-10% kunowejeli ye-silica encane enezimbobo, kanti ukuzinza kokushisa (350℃) kuphakeme ngo-150 ℃ kunejeli ye-silica encane enezimbobo. Ngakho-ke kufanelekile kakhulu ukusetshenziswa njenge-adsorption kanye ne-ejenti yokuhlukanisa izinga lokushisa eliguquguqukayo.

Ijeli ye-Alumino silica –AW
Lo mkhiqizo uhlobo lwe-alumino encane engangeni manzi enezimboboijeli ye-silicaNgokuvamile isetshenziswa njengengqimba yokuvikela yejeli ye-silica encane enezimbobo kanye nejeli ye-aluminium silica encane enezimbobo. Ingasetshenziswa yodwa uma amanzi amaningi (amanzi ahlanzekile) etholakala kuhlelo lokusebenza. Uma uhlelo lokusebenza lunamanzi ahlanzekile, kungatholakala iphuzu eliphansi lamazolo ngalo mkhiqizo.

Isikhwama esincane se-desiccant
I-desiccant yejeli ye-silica uhlobo lwezinto ezingenaphunga, ezingenambitheki, ezingenabuthi, ezimunca kakhulu futhi ezinamandla okumunca aqinile. Inesakhiwo samakhemikhali esizinzile futhi ayilokothi isabelane nanoma yiziphi izinto ngaphandle kwe-Alkai ne-Hydrofluoric acid, ephephile ukusetshenziswa nokudla kanye nemithi. I-desiccant yejeli ye-silica isusa umswakama ukuze idale indawo yomoya owomile ukuze igcinwe ngokuphephile. Lezi zikhwama zejeli ye-silica ziza ngobukhulu obuphelele kusukela ku-1g kuya ku-1000g - ukuze ikunikeze ukusebenza okuhle kakhulu.

Ijeli Elimhlophe Le-Silica
I-desiccant yejeli ye-Silica iyinto esebenza kakhulu ekumunceni, evame ukulungiswa ngokuphendula i-sodium silicate ne-sulfuric acid, ukuguga, i-acid bubble kanye nochungechunge lwezinqubo zangemva kokwelashwa. Ijeli ye-Silica iyisithako esingenasimo, futhi ifomula yayo yamakhemikhali yi-mSiO2. nH2O. Ayincibiliki emanzini nakunoma yisiphi isinyibilikisi, ayinabo ubuthi futhi ayinambitheki, inezakhiwo zamakhemikhali ezizinzile, futhi ayisebenzi nanoma iyiphi into ngaphandle kwesisekelo esiqinile ne-hydrofluoric acid. Ukwakheka kwamakhemikhali kanye nesakhiwo somzimba sejeli ye-silica kunquma ukuthi inezici okunzima ukuzishintsha ezinye izinto eziningi ezifanayo. I-desiccant yejeli ye-Silica inamandla aphezulu okumunceni, ukuzinza okuhle kokushisa, izakhiwo zamakhemikhali ezizinzile, amandla aphezulu omshini, njll.

Ijeli ye-Silica eluhlaza okwesibhakabhaka
Lo mkhiqizo unomphumela wokumuncwa kanye nokumelana nomswakama wejeli ye-silica enezimbobo ezincane, obonakala ngokuthi enkambisweni yokumuncwa komswakama, ingaba nsomi ngokunyuka kokumuncwa komswakama, futhi ekugcineni ibe bomvu kancane. Awukwazi nje ukukhombisa umswakama wendawo ezungezile, kodwa futhi ubonise ngokubonakalayo ukuthi ngabe udinga ukushintshwa nge-desiccant entsha. Ingasetshenziswa yodwa njenge-desiccant, noma ingasetshenziswa kanye nejeli ye-silica enezimbobo ezincane.
Ukuhlukaniswa: inkomba yeglue eluhlaza okwesibhakabhaka, iglue eluhlaza okwesibhakabhaka eshintsha umbala ihlukaniswe izinhlobo ezimbili: izinhlayiya eziyindilinga kanye nezinhlayiya zamabhulokhi.

Ijeli le-Silica eli-Orange
Ucwaningo kanye nentuthuko yalo mkhiqizo kusekelwe kujeli ye-silica eshintsha umbala wejeli eluhlaza okwesibhakabhaka, okuyijeli ye-silica eshintsha umbala e-orenji etholakala ngokufaka ijeli ye-silica enezimbobo ezincane ngengxube kasawoti ongaphili. Umkhiqizo usuyisizukulwane esisha semikhiqizo enobungani nemvelo ngezimo zawo zobuchwepheshe bokuqala kanye nokusebenza okuhle kokumuncwa.
Lo mkhiqizo usetshenziswa kakhulu kwi-desiccant futhi ubonisa izinga lokugcwala kwe-desiccant kanye nomswakama ohlobene wokupakisha okuvaliwe, amathuluzi okunemba namamitha, kanye nokumelana nomswakama kokupakisha okujwayelekile namathuluzi.
Ngaphezu kwezimpawu zeglue eluhlaza okwesibhakabhaka, iglue ewolintshi nayo inezinzuzo zokuthi ayinayo i-cobalt chloride, ayinabo ubuthi futhi ayinangozi. Uma isetshenziswa ndawonye, isetshenziselwa ukukhombisa izinga lokumuncwa komswakama kwe-desiccant, ukuze kutholakale umswakama ohlobene nendawo ezungezile. Isetshenziswa kabanzi emishinini enembile, kwezokwelapha, kwe-petrochemical, ekudleni, ezingutsheni, esikhumbeni, ezintweni zasekhaya nakwamanye amagesi ezimboni.
