Ijeli ye-silica ebomvu
Le mveliso inamasuntswana amile okwengqukuva okanye angaqhelekanga. Ibonakala ibomvu ebomvu okanye i-orenji ebomvu kunye nokufuma. Ukwakhiwa kwayo okuphambili yi-silicon dioxide kunye nokutshintsha kombala kunye nokufuma okwahlukileyo. Ngaphandle kokusebenza njengeblueijeli yesilika, ayinayo i-cobalt chloride kwaye ayinayo ityhefu, ayinabungozi.

Ijeli ye-alumino silica-AN
Ukubonakala kwe-aluminiyamijeli yesilikaityheli kancinane okanye imhlophe ibe sobala kunye nefomula yekhemikhali yemolekyuli mSiO2 • nAl2O3.xH2O. Iimpawu zeekhemikhali ezizinzileyo. Ukungatsha, akunyibiliki nakwesiphi na isinyibilikisi ngaphandle kwesiseko esomeleleyo kunye ne-hydrofluoric acid. Xa kuthelekiswa nejeli ye-silica ecolekileyo, umthamo we-adsorption womswakama ophantsi uyafana (ufana ne-RH = 10%, i-RH = 20%), kodwa umthamo we-adsorption wokufuma okuphezulu (okufana ne-RH = 80%, i-RH = 90%). I-6-10% ephezulu kune-gel ye-silica ecocekileyo, kunye nokuzinza kwe-thermal (350℃) yi-150 ℃ ephezulu kune-gel ye-silica ecocekileyo.

Ijeli ye-alumino silica –AW
Le mveliso luhlobo olucokisekileyo lwe-alumino enamanzi angenamanziijeli yesilika. Ngokuqhelekileyo isetyenziswa njengomaleko okhuselayo wejeli ye-silica ecolekileyo kunye nejeli ecolekileyo ye-aluminiyam ye-silica. Ingasetyenziswa yodwa kwimeko yomxholo ophezulu wamanzi asimahla (amanzi alulwelo). Ukuba inkqubo yokusebenza iqulethe amanzi angamanzi, indawo ephantsi yombethe inokufezekiswa ngale mveliso.

Isikhwama esincinci se-desiccant
I-silica gel desiccant luhlobo olungenavumba, olungenancasa, olungeyotyhefu, oluphezulu lokufunxa izinto ezinomthamo oqinileyo we-adsorption. Inepropathi ezinzileyo yeekhemikhali kwaye ayize iphendule ngayo nayiphi na into ngaphandle kwe-Alkai kunye ne-Hydrofluoric acid, ikhuselekile ukuba isetyenziswe ngokutya kunye Pharmaceuticals.Ijeli ye-silica ye-descicant ikhupha ukufuma ukudala indawo ekhuselayo yomoya owomileyo ukuze igcinwe ngokukhuselekileyo. Ezi ngxowa zejeli ze-silica ziza kuluhlu olupheleleyo lobungakanani ukusuka kwi-1g ukuya kwi-1000g-ukuze zikunike ukusebenza kakuhle.

Ijeli yeSilica emhlophe
I-silica gel desiccant yinto esebenzayo kakhulu ye-adsorption material, edla ngokulungiswa ngokuphendula i-sodium silicate kunye ne-sulfuric acid, ukuguga, i-bubble ye-asidi kunye nochungechunge lweenkqubo zonyango emva kokunyanga. Ijeli ye-silica yinto e-amorphous, kwaye i-chemical formula yayo yi-mSiO2. nH2O. I-insoluble emanzini kunye nayiphi na i-solvent, i-non-toxic kunye ne-tasteless, kunye neepropati ezizinzileyo zeekhemikhali, kwaye ayifuni nayiphi na into ngaphandle kwesiseko esinamandla kunye ne-hydrofluoric acid. Ukwakhiwa kweekhemikhali kunye nesakhiwo somzimba we-silica gel sinquma ukuba sineempawu ukuba ezinye izinto ezininzi ezifanayo kunzima ukuzitshintsha. I-silica gel desiccant inokusebenza okuphezulu kwe-adsorption, ukuzinza okuhle kwe-thermal, iipropati ezizinzileyo zeekhemikhali, amandla aphezulu omatshini, njl.

Ijeli yeSilica eluhlaza okwesibhakabhaka
Imveliso ine-adsorption kunye nefuthe lobungqina bobumanzi bejeli ye-silica ecolekileyo, ebonakaliswa ngokuba kwinkqubo yokufunxa ukufuma, inokujika ibemfusa ngokunyuka kokufunxa ukufuma, kwaye ekugqibeleni ijike ibebomvu. Ayinakubonisa kuphela ukufuma kokusingqongileyo, kodwa iphinde ibonise ngokubonakalayo ukuba ifuna ukutshintshwa nge-desiccant entsha. Ingasetyenziselwa yodwa njenge-desiccant, okanye ingasetyenziselwa kunye nejeli ye-silica ecocekileyo.
Ukwahlula: isalathisi seglue eluhlaza okwesibhakabhaka, iglue eluhlaza okwesibhakabhaka eguqula umbala ihlulwe ibe ziindidi ezimbini: amasuntswana angqukuva kunye namasuntswana ebhloko.

I-Orenji yeSilica Gel
Uphando kunye nophuhliso lwale mveliso lusekelwe kwijeli eluhlaza okwesibhakabhaka eguqula umbala we-silica gel, ijeli ye-silica eguqula umbala we-orenji efunyenwe ngokufaka ijeli ye-silica ecocekileyo kunye nomxube wetyuwa we-inorganic. ukungcoliseka kwendalo. Imveliso iye yaba sisizukulwana esitsha seemveliso ezihambelana nokusingqongileyo kunye neemeko zayo zokuqala zobuchwepheshe kunye nokusebenza kakuhle kwe-adsorption.
Le mveliso isetyenziselwa i-desiccant kwaye ibonisa iqondo lokuzaliswa kwe-desiccant kunye nomswakama ohambelanayo wokupakishwa okutywiniweyo, izixhobo ezichanekileyo kunye neemitha, kunye nobungqina bomswakama wokupakishwa ngokubanzi kunye nezixhobo.
Ukongeza kwiipropati zeglue eluhlaza okwesibhakabhaka, iglue ye-orange nayo inenzuzo yokungabikho kwe-cobalt chloride, i-non-toxic kwaye ingenabungozi. Isetyenziswe kunye, isetyenziselwa ukubonisa iqondo lokufunxa ukufuma kwe-desiccant, ukuze kuqinisekiswe ukufuma okuhambelana nokusingqongileyo. Isetyenziswe ngokubanzi kwizixhobo ezichanekileyo, amayeza, i-petrochemical, ukutya, iimpahla, isikhumba, izixhobo zasekhaya kunye nezinye iigesi zemizi-mveliso.
