Kuyambitsa zinthu zozungulira za 3A molecular sieve
3A molecular sieve ndi alkali metal aluminosilicate, yomwe imadziwikanso kuti 3A zeolite molecular sieve.3A mtundu wa molecular sieve umatanthawuza: Mtundu wa molecular sieve yomwe ili ndi Na + imatchedwa Na-A, ngati Na + yasinthidwa ndi K +, kukula kwa pore kumakhala pafupifupi 3A molecular sieve;3Sieve ya molekyulu imagwiritsidwa ntchito makamaka pakutsatsa madzi, ndipo simatsatsa molekyu iliyonse yokhala ndi mainchesi akulu kuposa 3A, ndi Desiccant yofunikira pakuyanika kwambiri, kuyenga ndi kutulutsa mpweya ndi magawo amadzimadzi m'mafakitale amafuta ndi mankhwala.
Njira yamankhwala: 2/3K2O · 1/3Na2O·Al2O3 · 2SiO2 · 9/2H2O
Si-Al chiŵerengero: SiO2/Al2O3≈2
Kukula kwa Pore: Pafupifupi 3Å
Mawonekedwe a 3A mtundu wa molecular sieve desiccant:
3Sieve ya ma molekyulu imakhala ndi liwiro lothamanga, mphamvu yophwanyira mwamphamvu komanso mphamvu yolimbana ndi kuipitsidwa, zomwe zimawonjezera kugwiritsa ntchito mphamvu ya sieve yama cell ndikutalikitsa moyo wautumiki wa sieve ya maselo.
1. 3Sieve ya molekyulu imachotsa madzi: zimatengera kupanikizika, kutentha ndi madzi omwe ali mu gasi.Mpweya wowumitsa pa 200℃ 350℃ ndi 0.3 ~ 0.5Kg/square centimita, umadutsa pa bedi la molecular sieve kwa maola 3～4, ndipo kutentha kotuluka ndi 110℃ 180℃ kuti utakhazikika.
2. 3Sieve ya molekyulu yochotsa zinthu zachilengedwe: sinthani zinthu zamoyo ndi nthunzi wamadzi, kenako chotsani madzi.
Kuchuluka kwa kugwiritsa ntchito adsorbent 3A molecular sieve:
3A molecular sieve imagwiritsidwa ntchito makamaka mumakampani opanga magalasi, kuyenga gasi ndi kuyeretsa komanso mafakitale a petrochemical.
1.3A Kuyanika kwa molekyulu yamadzimadzi osiyanasiyana (monga ethanol)
2. Kuyanika mpweya
3. Kuyanika kwa refrigerant
4.3Kuyanika kwa molecular sieve ya gasi wachilengedwe ndi mpweya wa methane
5. Kuyanika kwa unsaturated hydrocarbons ndi gasi wosweka, ethylene, acetylene, propylene, butadiene, kuyanika kwamafuta osweka amafuta ndi olefins.
Opanga ma molekyulu a sieve 3A mtundu wa molecular sieve zizindikiro zaukadaulo:
muyezo wokhazikitsa: GB/T 10504-2008
Opanga ma molekyulu a sieve 3A kuyika ndi kusungirako sieve ya maselo:
3A molecular sieve Kusungirako: M'nyumba yokhala ndi chinyezi chosaposa madigiri 90: pewani madzi, asidi, alkali, ndi mpweya wakutali kuti musungidwe.
3A ma CD sieve maselo: 30Kg losindikizidwa zitsulo ng'oma, 150Kg losindikizidwa zitsulo ng'oma, 130Kg losindikizidwa zitsulo ng'oma (kuvula).
Mafotokozedwe Akatundu:
Kukula kwa pore kwa 3A molecular sieve ndi 3A.Amagwiritsidwa ntchito kwambiri potsatsa madzi, ndipo samatsatsa mamolekyu aliwonse okhala ndi mainchesi akulu kuposa 3A.Malinga ndi mawonekedwe a ntchito zamafakitale, ma sieve a maselo omwe timapanga ndi Gloria amakhala ndi liwiro lothamanga kwambiri, nthawi yosinthika kwambiri, yokwera Mphamvu yakuphwanyira komanso kuthekera kolimbana ndi kuipitsidwa kumawonjezera kugwiritsa ntchito bwino kwa sieve zama cell ndikutalikitsa moyo wautumiki wa sieve za maselo.
Kusamalitsa:
Masefa a mamolekyu amayenera kupewedwa kuti asatengere madzi, mpweya wachilengedwe kapena zakumwa musanagwiritse ntchito, apo ayi, ayenera kupangidwanso.
