Ijeli ye-silica ebomvu
Lo mkhiqizo uyindilinga noma uyizinhlayiya ezinomumo ongajwayelekile.Kubonakala kubomvu okunsomi noma okuwolintshi kunomswakama.Ukwakheka kwayo okuyinhloko i-silicon dioxide kanye nokushintsha kombala kunomswakama ohlukile.Ngaphandle kokusebenza njenge-bluei-silica gel, ayinayo i-cobalt chloride futhi ayinabo ubuthi, ayinabungozi.

Ijeli ye-Alumino silica-AN
Ukubonakala kwe-aluminiumi-silica gelinombala ophuzi kancane noma omhlophe obonisa ngale kanye nefomula yekhemikhali yemolekyuli mSiO2 • nAl2O3.xH2O.Izakhiwo zamakhemikhali ezizinzile.Ayishi, ayincibiliki kunoma isiphi isincibilikisi ngaphandle kwesisekelo esiqinile ne-hydrofluoric acid.Uma kuqhathaniswa nejeli ye-silica enezimbobo ezinhle, umthamo wokukhangisa womswakamo ophansi uyafana (ofana no-RH = 10%, RH = 20%), kodwa umthamo wokukhangisa womswakamo ophezulu (ofana no-RH = 80%, RH = 90%) Iphakeme ngo-6-10% kunaleyo yejeli ye-silica ecwebezelayo, kanye nokuzinza okushisayo (350℃) kuphakeme ngo-150 ℃ kunejeli ye-silica enezimbobo ezinhle.

Ijeli ye-alumino silica -AW
Lo mkhiqizo uwuhlobo lwe-alumino eqinile enezimbobo emanzinii-silica gel.Ngokuvamile isetshenziswa njengongqimba oluvikelayo lwejeli ye-silica enezimbobo ezinhle kanye nejeli ye-silica ecwebezelayo ye-aluminium.Ingasetshenziswa yodwa esimweni sokuqukethwe okuphezulu kwamanzi amahhala (amanzi awuketshezi).Uma uhlelo lokusebenza luqukethe amanzi awuketshezi, indawo ephansi yamazolo ingafinyelelwa ngalo mkhiqizo.

Isikhwama esincane se-desiccant
I-silica gel desiccant iwuhlobo lwezinto ezingenaphunga, ezingenakunambitheka, ezingenabuthi, ezimunca umsebenzi ophezulu ezinamandla okukhangayo okuqinile. Inempahla yamakhemikhali ezinzile futhi ayilokothi isabele nanoma yiziphi izinto ngaphandle kwe-Alkai ne-Hydrofluoric acid, ephephile ukusetshenziswa nokudla kanye imithi.I-silica gel descicant isusa umswakama ukuze idale indawo evikelayo yomoya owomile ukuze igcinwe ngendlela ephephile.Lezi zikhwama zejeli ze-silica ziza ngosayizi ogcwele kusukela ku-1g kuya ku-1000g - ukuze zikunikeze ukusebenza okuphelele.

Ijeli Yesilika Emhlophe
I-silica gel desiccant iyinhlangano ye-adsorption esebenzayo kakhulu, evame ukulungiswa ngokuphendula i-sodium silicate nge-sulfuric acid, ukuguga, i-bubble ye-asidi kanye nochungechunge lwezinqubo zokwelashwa emva kokwelashwa.Ijeli ye-silica iyinto e-amorphous, futhi ifomula yayo yamakhemikhali yi-mSiO2.nH2O.Ayincibiliki emanzini nakunoma iyiphi i-solvent, ayinabuthi futhi ayinambitheki, inezinto zamakhemikhali ezizinzile, futhi ayisebenzi nganoma iyiphi into ngaphandle kwesisekelo esiqinile ne-hydrofluoric acid.Ukwakheka kwamakhemikhali kanye nesakhiwo somzimba sejeli ye-silica inquma ukuthi inezici ukuthi ezinye izinto eziningi ezifanayo okunzima ukuzishintsha.I-silica gel desiccant inokusebenza okuphezulu kwe-adsorption, ukuzinza okuhle kwe-thermal, izakhiwo zamakhemikhali ezinzile, amandla aphezulu emishini, njll.

Ijeli ye-Silica eluhlaza okwesibhakabhaka
Umkhiqizo unomphumela wokukhangisa kanye nobufakazi bomswakama wejeli ye-silica ene-fine-pored, ebonakala ngokuthi ngesikhathi sokumuncwa umswakama, ingaphenduka ibe nsomi ngokwanda kokumuncwa komswakama, futhi ekugcineni iphenduke ibebomvu.Ayikwazi ukukhombisa kuphela umswakama wemvelo, kodwa futhi ibonise ngokubukeka ukuthi idinga ukushintshwa nge-desiccant entsha.Ingasetshenziswa yodwa njenge-desiccant, noma ingasetshenziswa ngokuhambisana nejeli ye-silica efakwe kahle.
Ukuhlukaniswa: inkomba yeglue eluhlaza okwesibhakabhaka, iglue eluhlaza okwesibhakabhaka eshintsha umbala ihlukaniswe yaba izinhlobo ezimbili: izinhlayiya eziyindilinga kanye nezinhlayiya zebhulokhi.

I-Orange Silica Gel
Ucwaningo nokuthuthukiswa kwalo mkhiqizo kusekelwe kujeli ye-silica yejeli eluhlaza okwesibhakabhaka, okuyijeli ye-silica eshintsha umbala osawolintshi etholwe ngokufaka ijeli yesilika enezimbotshana ezinhle ngengxube kasawoti ongaphili.ukungcoliswa kwemvelo.Umkhiqizo usuphenduke isizukulwane esisha semikhiqizo evumelana nemvelo ngezimo zayo zangempela zobuchwepheshe kanye nokusebenza okuhle kwe-adsorption.
Lo mkhiqizo usetshenziselwa kakhulu i-desiccant futhi ubonisa izinga lokugcwala kwe-desiccant kanye nomswakama ohlobene wamaphakheji avaliwe, amathuluzi anembile namamitha, kanye nomswakama-ubufakazi bokupakishwa okujwayelekile nezinsimbi.
Ngaphandle kwezakhiwo zeglue eluhlaza okwesibhakabhaka, i-orange glue nayo inezinzuzo zokungabi ne-cobalt chloride, engeyona enobuthi futhi engenabungozi.Isetshenziswa ndawonye, isetshenziselwa ukukhombisa izinga lokumuncwa komswakama we-desiccant, ukuze kunqunywe umswakama ohlobene nendawo ezungezile.Isetshenziswa kakhulu kumathuluzi anembayo, umuthi, i-petrochemical, ukudla, izingubo, isikhumba, izinto zikagesi zasendlini namanye amagesi ezimboni.
