Nzira yekushandisa sei 4A molecular sieve?Ndezvipi zvinodiwa kune nharaunda yainoshanda mairi?Sechinhu chine porous, 4A molecular sieve inoshandiswa zvakanyanya muminda yakawanda nekuda kweiyo microporous molecular sieve se adsorption separation material, ion exchange material uye catalytic material.
Kutanga, ngatitarisei kuunzwa kwe4A molecular sieve:
Nekuti saizi yepore inoshanda 0.4nm, inodaidzwa kuti 4A molecular sieve, inogona kudsorb yakaderera mamorekuru semvura, methanol, ethanol, carbon dioxide, ethylene, sulfur dioxide, hydrogen sulfide, uye propylene.
- 1. Kukura kwema molecular nzira yekushandisa 4A molecular sieve
Nekuti saizi yepore inobudirira i 0.4mm, haikwanise kushambadza chero mamorekuru (kusanganisira propane) ine dhayamita yakakura kupfuura 0.4mm, asi sarudzo yaro yeadsorption yemvura yakakwira kupfuura chero mamwe mamorekuru, uye ndeimwe yeanonyanya kushandiswa mamorekuru. sieve mhando mumaindasitiri.
- Nzvimbo yekushanda yekushandiswa nzira ye4A molecular sieve
1. Kana kutonhora kuri 110 ° C, zvinokwanisika kubudisa mvura munzvimbo huru, asi haizodzingi kunze kwemvura mumapores e molecular sieve.Nokudaro, murabhoritari, inogona kushandiswa uye kupera mvura nekuoma muchoto chemuffle.Iyo tembiricha ndeye 350 ° C, uye yakaomeswa pasi pekumanikidzwa kwakajairika kwemaawa masere (kana paine pombi yevacuum, inogona kuomeswa pa150 ° C kwemaawa mashanu).
2. The activated 4A molecular sieve inotonhodzwa kusvika ku200 ° C (anenge maminitsi maviri) mumhepo, uye inoda kuchengetwa mu desiccator pakarepo.
3. Munzvimbo inobvumirwa, kuchengetedzwa kwe nitrogen yakaoma kunofanira kushandiswa panguva yekutonhora nekuchengetedza, iyo inogona kunyatsodzivirira mhute yemvura mumhepo kubva pakushambadza zvakare.Nokuti iyo yekare molecular sieve mushure mekushandiswa ine tsvina, haifaniri kungoshandiswa chete pakupisa kwe450 ° C, asiwo mhute yemvura kana inert gas (nitrogen, nezvimwewo) inofanira kuiswa kuti itsive zvimwe zvinhu mu molecular sieve.
4. Dzivisa mafuta uye mvura yemvura paunenge uchishandisa, uye edza kudzivisa kusangana zvakananga nemafuta nemvura yemvura.
Seye alkali simbi aluminosilicate, 4A molecular sieve inofarirwa nevatengi vazhinji mukuomeswa kwegasi uye mvura, uye inogona zvakare kushandiswa kunatsa nekuchenesa gasi kana mvura, sekubvisa argon.Zvino, unonzwisisa here matanho ekuchengetedza kushandiswa kwayo?
