3a iisefu zemolekyuli: Uphawu kunye nesicelo

Ukuqaliswa kweemveliso ze-3A ze-molecular sieve

I-3A i-molecular sieve yi-alkali metal aluminosilicate, eyaziwa ngokuba yi-3A ye-zeolite ye-molecular sieve.I-3A uhlobo lwe-molecular sieve lubhekiselele ku: Uhlobo lwe-molecular sieve equkethe i-Na + ichazwa njenge-Na-A, ukuba i-Na + ifakwe endaweni ye-K +, ubukhulu bepore malunga ne-3A ye-molecular sieve;I-3A i-molecular sieve isetyenziselwa ukubhengeza amanzi, kwaye ayibhengezi nayiphi na i-molecule enobubanzi obukhulu kune-3A, i-Desiccant iyimfuneko ukomisa okunzulu, ukucocwa kunye ne-polymerization yezigaba zegesi kunye ne-liquid kwi-petroleum kunye ne-chemical industry.
Ifomula yemichiza: 2/3K2O · 1/3Na2O · Al2O3 · 2SiO2 · 9/2H2O
Umlinganiselo we-Si-Al: SiO2/Al2O3≈2
Ubungakanani bePore obusebenzayo: Malunga ne-3Å
Iimpawu ze-3A uhlobo lwe-molecular sieve desiccant:

I-3I-molecular sieve inesantya esikhawulezayo se-adsorption, amandla okutyumza okuqinileyo kunye nokukwazi ukuchasana nongcoliseko, okwandisa ukusetyenziswa kakuhle kwe-molecular sieve kunye nokwandisa ubomi benkonzo ye-molecular sieve.
1. 3Isihluzo semolekyuli sisusa amanzi: kuxhomekeke kuxinzelelo, ubushushu kunye nomxholo wamanzi werhasi.Irhasi yokomisa kwi-200～350℃ yi-0.3～0.5Kg/square centimeter, idlula kwibhedi ye-molecular sieve iiyure eziyi-3～4, kwaye iqondo lobushushu lokuphuma liyi-110～180℃ ukuze lipholiswe.
2. 3Ukususwa kwesefo yemolekyuli yezinto eziphilayo: buyisela izinto eziphilayo ngomphunga wamanzi, uze ususe amanzi.

Umda wokusetyenziswa kwesefa ye-adsorbent 3A yemolekyuli:

I-3Isefa yemolekyuli isetyenziswa ikakhulu kushishino lweglasi loyilo, ukucokisa igesi kunye nokucocwa kunye neshishini lepetrochemical.
1.3A Ukomiswa kwesefo yeemolekyuli zolwelo olwahlukeneyo (ezifana ne-ethanol)
2. Ukomisa umoya
3. Ukomisa ifriji
4.3 Ukomiswa kwe-molecular sieve yegesi yendalo kunye negesi yemethane
5. Ukomisa ii-hydrocarbons ezingaxutywanga kunye negesi eqhekekileyo, i-ethylene, i-acetylene, i-propylene, i-butadiene, ukomiswa kwe-petroleum eqhekekileyo yegesi kunye ne-olefins

Abavelisi be-molecular sieve 3A uhlobo lwezalathi zobugcisa ze-molecular sieve: 

umgangatho wokuphunyezwa: GB/T 10504-2008
Abavelisi be-molecular sieve 3A ukupakishwa kunye nokugcinwa kwesefo yemolekyuli:

I-3A ye-molecular sieve Ugcino: Ngaphakathi kunye nomswakama ongekho ngaphezu kwe-90 degrees: kunqanda amanzi, i-asidi, i-alkali, kunye nomoya ozimeleyo ukuze ugcinwe.
I-3A ukupakishwa kwe-molecular sieve: 30Kg igubu lentsimbi elitywiniweyo, i-150Kg igubu lentsimbi elitywiniweyo, i-130Kg igubu lentsimbi elitywiniweyo (umcu).
Ingcaciso yeMveliso:
Ubungakanani bepore ye-3A ye-molecular sieve yi-3A.Isetyenziswa ikakhulu kwintengiso yamanzi, kwaye ayibhengezi naziphi na iimolekyuli ezinobubanzi obungaphezulu kwe-3A.Ngokweempawu zokusetyenziswa kwemizi-mveliso, iisefu zemolekyuli esizivelisayo nguGloria zinesantya esikhawulezayo sokubhengeza, amaxesha amaninzi okuhlaziya, aphezulu Amandla okutyumza kunye nobuchule bokuchasana nokungcoliseka kwendalo kwandisa ukusebenza kakuhle kweesefu zemolekyuli kunye nokwandisa ubomi benkonzo yeesefu zemolekyuli.

Ukulumkela:
Iisefu zeemolekyuli kufuneka zithintelwe ekubhengezeni amanzi, iigesi eziphilayo okanye ulwelo ngaphambi kokusetyenziswa, ngaphandle koko, kufuneka zihlaziywe.
