I-Desiccant ivame kakhulu ekuphileni kwansuku zonke.Ngokuvamile, ungathenga izikhwama zokudla zamantongomane, ezine-desiccant.Inhloso ye-desiccant ukunciphisa umswakama womkhiqizo futhi uvimbele umkhiqizo ukuthi ungonakaliswe umswakama, ngaleyo ndlela uthinte ikhwalithi yomkhiqizo.Nambitha.Nakuba indima ye-desiccant iwukuba ukumunca umswakama womoya emkhiqizweni, isimiso sokusebenzisa nezinto zokwakha zihlukile.Kunezinhlobo ezimbili ngokusho kwe-chemistry kanye ne-physics:
I-ejenti yokomisa amakhemikhali:
I-calcium chloride desiccant
I-Calcium chloride yenziwa ikakhulukazi nge-calcium carbonate ephezulu ne-hydrochloric acid njengezinto zokusetshenziswa.Kuye kwacwengwa ngokusabela kokusabela, ukuhlunga, ukuhwamuka, ukugxila kanye nokomisa.Ivame ukusetshenziswa njenge-calcium fortifier, i-chelating agent, i-ejenti yokwelapha kanye ne-desiccant embonini yokudla.Ngaphezu kwalokho, ibuye isetshenziswe njenge-desiccant yamagesi.Ingasetshenziselwa ukomisa amagesi angathathi hlangothi, ane-alkaline noma ane-asidi futhi isetshenziswa njenge-ejenti eqeda amanzi emzimbeni ukuze kukhiqizwe ama-ethers, utshwala, ama-propylene resins, njll. I-Calcium chloride iningi layo liyizimbotshana, i-granular noma i-honeycomb material, ayinaphunga, ukunambitheka okubaba kancane, kuyancibilika. emanzini futhi engenambala.
2. Quicklime desiccant
Ingxenye yayo eyinhloko i-calcium oxide, efinyelela ukumuncwa kwamanzi ngokusabela kwamakhemikhali, ingomisa igesi engathathi hlangothi noma ye-alkaline, futhi ayinakuguqulwa.Okuvame kakhulu ukusetshenziswa kwama-desiccants anjalo "kumaqebelengwane eqhwa".Ngaphezu kwalokho, ibuye isetshenziswe kaningi ezintweni zikagesi, isikhumba, izingubo, izicathulo, itiye, njll., kodwa njengoba i-quicklime iyi-alkali eqinile, igqwala kakhulu, futhi lapho amehlo asebekhulile nezingane alimala, kancane kancane iba Yaqedwa.
I-Desiccant yomzimba:
I-silika gel desiccant
Ingxenye eyinhloko i-silica, ene-granulated noma ubuhlalu ngamaminerali emvelo.Njenge-desiccant, isakhiwo sayo se-microporous sinokuhlangana okuhle kwama-molecule amanzi.Indawo efanelekile yokumunca umswakama yejeli yesilika izinga lokushisa legumbi (20~32 °C) kanye nomswakama ophezulu (60~90%), okunganciphisa umswakama ohlobene nendawo ezungezile ufinyelele cishe ku-40%.I-silica gel desiccant inezici zokungabi nambala, ezingenaphunga futhi ezingenabuthi, ezinzile kumakhemikhali amakhemikhali futhi zingcono ekusebenzeni kokumunca umswakama.Isetshenziswa kakhulu kumathuluzi, izinsimbi, isikhumba, imithwalo, ukudla, izindwangu, izinto zokusebenza nokunye.Indima yayo ukulawula umswakama ohlobene nendawo ezungezile ngesikhathi sokugcinwa nokuthutha ukuvimbela umswakama, isikhutha kanye nokugqwala.Kuyaphawuleka ukuthi lena ukuphela kwe-desiccant evunyelwe e-EU.
3. Ubumba (montmorillonite) desiccant
Ukubukeka komumo njengebhola elimpunga, elifaneleka kakhulu ukumunca umswakama endaweni elandelayo engaphansi kuka-50 °C.Uma izinga lokushisa lingaphezu kuka-50 ° C, izinga "lokukhululwa kwamanzi" lobumba likhulu kunezinga "lokumuncwa kwamanzi".Kodwa inzuzo yobumba ukuthi ishibhile.I-desiccant isetshenziswa kabanzi ekunakekelweni kwezempilo kwezokwelapha, ukupakisha ukudla, izinsimbi zokukhanya, imikhiqizo ye-elekthronikhi, imikhiqizo yezempi kanye nemikhiqizo yabantu.Ngenxa yokuthi isebenzisa i-bentonite ehlanzekile yemvelo eluhlaza, inezici ze-adsorption eqinile, i-adsorption esheshayo, engenambala, engenabuthi, akukho ukungcoliswa kwemvelo futhi akukho ukugqwala kokuxhumana.Ihambisana nemvelo, ayinambala futhi ayinabo ubuthi, ayinawo umonakalo emzimbeni womuntu, futhi inokusebenza okuhle kwe-adsorption.Umsebenzi we-Adsorption, ukukhishwa kwe-static kanye nokususwa kwephunga.
