Ijeli yesilika ebomvu
Le mveliso inamasuntswana angqukuva okanye angaqhelekanga. Ibonakala ibomvu ngombala omfusa okanye o-orenji kwaye ifumile. Eyona nto iphambili yenziwe yi-silicon dioxide kwaye umbala uyatshintsha xa kufuma okwahlukileyo. Ngaphandle kokusebenza okufana noluhlaza okwesibhakabhakaijeli yesilika, ayinayo i-cobalt chloride kwaye ayinabungozi, ayinabungozi.

Ijeli ye-Alumino silica–AN
Inkangeleko ye-aluminiumijeli yesilikainombala otyheli okanye omhlophe ocacileyo ngefomula yemolekyuli yekhemikhali mSiO2 • nAl2O3.xH2O. Iimpawu zeekhemikhali ezizinzileyo. Ayitshi, ayinyibiliki nakweyiphi na i-solvent ngaphandle kwesiseko esomeleleyo kunye ne-hydrofluoric acid. Xa kuthelekiswa nejeli ye-silica ethambileyo enemibhobho, umthamo wokufunxa womswakama ophantsi uyafana (njenge-RH = 10%, RH = 20%), kodwa umthamo wokufunxa womswakama ophezulu (njenge-RH = 80%, RH = 90%) uphezulu nge-6-10% kunejeli ye-silica ethambileyo enemibhobho, kwaye uzinzo lobushushu (350℃) luphezulu nge-150 ℃ kunejeli ye-silica ethambileyo enemibhobho. Ngoko ke ifanelekile kakhulu ukusetyenziswa njenge-adsorption kunye ne-separation agent yobushushu obuguquguqukayo.

Ijeli ye-Alumino silica –AW
Le mveliso luhlobo lwe-alumino entle engenamanzi enemingxumaijeli yesilikaNgokuqhelekileyo isetyenziswa njengomaleko okhuselayo wejeli ye-silica ethambileyo enemibhobho kunye nejeli ye-aluminium silica ye-aluminium ethambileyo enemibhobho. Ingasetyenziswa yodwa kwimeko yamanzi amaninzi asimahla (amanzi acocekileyo). Ukuba inkqubo yokusebenza inamanzi acocekileyo, inqanaba eliphantsi lombethe lingafumaneka ngale mveliso.

Ingxowa encinci yedesiccant
I-desiccant yejeli ye-silica luhlobo lwezinto ezingenavumba, ezingenancasa, ezingenabungozi, ezifunxa kakhulu kwaye zinamandla amakhulu okufunxa. Ineempawu zekhemikhali ezizinzileyo kwaye ayisebenzi nakwezinye izinto ngaphandle kwe-Alkai kunye ne-Hydrofluoric acid, ekhuselekileyo ukusetyenziswa kunye nokutya kunye namayeza. I-desiccant yejeli ye-silica isusa umswakama ukuze idale umoya owomileyo okhuselekileyo ukuze ugcinwe ngokukhuselekileyo. Ezi ngxowa zejeli ye-silica ziza kuluhlu olupheleleyo lobukhulu ukusuka kwi-1g ukuya kwi-1000g - ukuze ikunike ukusebenza okuphezulu.

Ijeli yeSilica emhlophe
I-desiccant yejeli ye-silica sisixhobo esisebenza kakhulu sokufunxa, esidla ngokulungiswa ngokuphendula i-sodium silicate kunye ne-sulfuric acid, ukuguga, i-acid bubble kunye nothotho lweenkqubo emva konyango. Ijeli ye-silica yinto engabonakaliyo, kwaye ifomula yayo yekhemikhali yi-mSiO2. nH2O. Ayinyibiliki emanzini nakweyiphi na i-solvent, ayinatyhefu kwaye ayinancasa, ineempawu zeekhemikhali ezizinzileyo, kwaye ayitshintshi nantoni na ngaphandle kwesiseko esomeleleyo kunye ne-hydrofluoric acid. Ukwakheka kweekhemikhali kunye nolwakhiwo lomzimba lwejeli ye-silica kuqinisekisa ukuba ineempawu zokuba ezinye izinto ezininzi ezifanayo kunzima ukuzitshintsha. I-desiccant yejeli ye-silica inomsebenzi ophezulu wokufunxa, uzinzo oluhle lobushushu, iimpawu zeekhemikhali ezizinzileyo, amandla aphezulu oomatshini, njl.

Ijeli yeSilica eluhlaza okwesibhakabhaka
Le mveliso ine-adsorption kunye ne-effective effect ye-fine-pored silica gel, ebonakala ngokuba kwinkqubo yokufunxwa komswakama, inokutshintsha ibe mfusa ngokunyuka kokufunxwa komswakama, kwaye ekugqibeleni ibe bomvu kancinci. Ayinakubonisa kuphela ukufuma kwendalo, kodwa ikwabonisa ngokubonakalayo ukuba ingaba kufuneka itshintshwe yi-desiccant entsha. Ingasetyenziswa yodwa njenge-desiccant, okanye ingasetyenziswa kunye ne-fine-pored silica gel.
Ulwahlulo: isibonisi seglue eluhlaza okwesibhakabhaka, iglue eluhlaza okwesibhakabhaka etshintsha umbala yahlulwe yaba ziintlobo ezimbini: ii-particles ezingqukuva kunye nee-block particles.

Ijeli yeSilica yeorenji
Uphando nophuhliso lwale mveliso lusekelwe kwijeli ye-silica etshintsha umbala wejeli eluhlaza okwesibhakabhaka, eyijeli ye-silica etshintsha umbala eorenji efunyenwe ngokufunxa ijeli ye-silica enemingxuma emincinci ngomxube wetyuwa enga-organic. Le mveliso ibe sisizukulwana esitsha seemveliso ezinobuhlobo nokusingqongileyo ezineemeko zayo zobugcisa zokuqala kunye nokusebenza kakuhle kokufunxa.
Le mveliso isetyenziselwa kakhulu i-desiccant kwaye ibonisa inqanaba lokugcwala kwe-desiccant kunye nokufuma okunxulumene nokupakishwa okuvaliweyo, izixhobo ezichanekileyo kunye neemitha, kunye nokumelana nokufuma kwephakheji kunye nezixhobo ngokubanzi.
Ukongeza kwiimpawu zeglue eluhlaza okwesibhakabhaka, iglue e-orenji ikwanazo neengenelo zokuba ayinayo i-cobalt chloride, ayinatyhefu kwaye ayinabungozi. Xa isetyenziswa kunye, isetyenziselwa ukubonisa ubungakanani bokufunxwa komswakama kwe-desiccant, ukuze kuchongwe ukufuma okunxulumene nendawo esingqongileyo. Isetyenziswa kakhulu kwizixhobo ezichanekileyo, amayeza, iikhemikhali, ukutya, iimpahla, ulusu, izixhobo zasekhaya kunye nezinye iigesi zoshishino.
