I-Desiccant ixhaphake kakhulu kubomi bemihla ngemihla.Ngokuqhelekileyo, unokuthenga iingxowa zokutya ze-nut, ezine-desiccant.Injongo ye-desiccant kukunciphisa umswakama wemveliso kunye nokukhusela imveliso ukuba ihlaselwe ngumswakama, ngaloo ndlela ichaphazela umgangatho wemveliso.Ngcamla.Nangona indima ye-desiccant kukuthatha umswakama womoya kwimveliso, umgaqo wokusetyenziswa kunye nezinto eziphathekayo zihlukile.Kukho iindidi ezimbini ngokwekhemistri kunye nefiziksi:
Iarhente yokomisa ngamachiza:
Calcium chloride desiccant
I-Calcium chloride yenziwe ikakhulu ngekhwalithi ephezulu ye-calcium carbonate kunye ne-hydrochloric acid njengemathiriyeli ekrwada.Ihlanjululwe yi-reaction synthesis, filtration, evaporation, concentration kunye nokomisa.Ihlala isetyenziswa njenge-calcium fortifier, i-chelating agent, i-ejenti yokunyanga kunye ne-desiccant kwishishini lokutya.Ukongeza, ikwasetyenziswa njenge-desiccant yeegesi.Ingasetyenziselwa ukomisa igesi engathathi hlangothi, i-alkaline okanye i-asidi kwaye isetyenziswe njenge-arhente yokukhupha amanzi ekuveliseni i-ethers, i-alcohol, i-propylene resins, njl. emanzini kwaye engenambala.
2. Quicklime desiccant
Inxalenye yayo ephambili yi-calcium oxide, efikelela ukufunxwa kwamanzi ngokusabela kweekhemikhali, inokomisa igesi engathathi hlangothi okanye i-alkaline, kwaye ayinakuguqulwa.Eyona nto ixhaphakileyo kukusetyenziswa kwe-desiccants enjalo "kwikhekhe leqhwa".Ukongeza, ikwasetyenziswa rhoqo kwizixhobo zombane, isikhumba, iimpahla, izihlangu, iti, njl., kodwa ekubeni i-quicklime iyi-alkali eyomeleleyo, iyonakalisa kakhulu, kwaye xa amehlo abantu abadala kunye nabantwana benzakala ngokuthe ngcembe uye wapheliswa.
I-Desiccant yomzimba:
Ijeli ye-silika desiccant
Inxalenye ephambili yi-silica, ehlanjululwe okanye ifakwe ngamaso ngamaminerali endalo.Njenge-desiccant, isakhiwo sayo se-microporous sinobudlelwane obuhle beamolekyu zamanzi.Eyona ndawo ifanelekileyo yokufunxa ukufuma kwejeli ye-silica bubushushu begumbi (20~32 °C) kunye nokufuma okuphezulu (60~90%), okunokunciphisa ukufuma okunxulumene nokusingqongileyo ukuya kuma-40%.I-silica gel desiccant ineempawu ezingenambala, ezingenavumba kwaye ezingenayo ityhefu, izinzile kwiipropati zeekhemikhali kwaye zingcono ekusebenzeni komswakama.Isetyenziswe kakhulu kwizixhobo, izixhobo, isikhumba, imithwalo, ukutya, iingubo, izixhobo kunye nokunye.Indima yayo kukulawula ukufuma okunxulumene nokusingqongileyo ngexesha lokugcinwa kunye nokuthutha ukuthintela ukufuma, ukungunda kunye nerusi.Kuyafaneleka ukuba uqaphele ukuba le kuphela i-desiccant evunyiweyo kwi-EU.
3. Udongwe (montmorillonite) desiccant
Imilo yenkangeleko njengebhola engwevu, eyona ifanelekele ukufunxa ukufuma kwimekobume engaphantsi kwama-50 °C.Ukuba iqondo lokushisa liphezulu kune-50 ° C, iqondo "lokukhululwa kwamanzi" lodongwe likhulu kunomlinganiselo "wokuxutywa kwamanzi".Kodwa ingenelo yodongwe kukuba alunaxabiso.I-desiccant isetyenziswa ngokubanzi kukhathalelo lwempilo yezonyango, ukupakishwa kokutya, izixhobo ze-optical, iimveliso ze-elektroniki, iimveliso zomkhosi kunye neemveliso zabantu.Ngenxa yokuba isebenzisa i-bentonite yendalo ecocekileyo yendalo, ineempawu ze-adsorption eqinile, i-adsorption ekhawulezayo, engenambala, engeyona inetyhefu, akukho ngcoliseko yendalo kwaye akukho corrosion yokunxibelelana.Ihambelana nokusingqongileyo, ayinambala kwaye ayinayo ityhefu, ayinamonakalo emzimbeni womntu, kwaye inokusebenza kakuhle kwe-adsorption.Umsebenzi we-Adsorption, ukuchithwa kwe-static kunye nokususwa kwevumba.
