4Sieve ea molek'hule & 13X sieve ea molek'hule

4A molecular sieve chemical formula: Na₂O·Al₂O₃·2SiO₂·4.5H₂O ₃
Molao-motheo oa ts'ebetso oa sieve ea limolek'hule o amana haholo le boholo ba pore ea sieve ea molek'hule, e ka khonang ho hlahisa limolek'hule tsa khase tseo bophara ba tsona ba molek'hule bo leng nyane ho feta boholo ba pore, 'me boholo ba pore bo boholo, matla a ho ba le adsorption a maholo. Boholo ba lesoba le fapane, 'me lintho tse tlhotliloeng li fapane. 4a sieve ea molek'hule, limolek'hule tse adsorbed le tsona li tlameha ho ba ka tlase ho 0.4nm.
4Lisefa tsa molek'hule li sebelisoa haholo ho omisa khase ea tlhaho le likhase tse fapaneng tsa lik'hemik'hale le maro, lihatsetsi, lithethefatsi, data ea elektroniki le lintho tse senyehang, ho hloekisa argon le ho arola methane, ethane le propane. Haholo-holo e sebelisetsoa ho omisa ka botebo ba likhase le lino tse kang moea, khase ea tlhaho, li-hydrocarbon le lihatsetsi; Tokisetso le tlhoekiso ea argon; Ho omisa ka mokhoa o tsitsitseng oa likarolo tsa elektronike le lisebelisoa tse senyehang; Li-dehydrating agents ka lipente, li-polyester, lidae le liphahlo.

Sieve ea mofuta oa 13X, eo hape e tsejoang e le sodium X mofuta oa molek'hule sieve, ke alkali metal silicaluminate, e na le alkaline e itseng, ke ea sehlopha sa metheo e tiileng.
Mokhoa oa eona oa lik'hemik'hale ke Na2O· Al2O3 · 2.45SiO2 · 6.0H20,
Boholo ba pore ea eona ke 10A 'me e bapatsa molek'hule efe kapa efe e kholo ho feta 3.64A le ka tlase ho 10A.
13x e sebelisoa haholo ho:
1) Tlhoekiso ea khase ka sesebelisoa sa karohano ea moea ho tlosa metsi le carbon dioxide.
2) Ho omisa le ho senya khase ea tlhaho, khase ea oli ea mokelikeli le li-hydrocarbon tse metsi.
3) Ho omisa botebo ba khase ka kakaretso. Sieve ea mofuta oa 13X, eo hape e tsejoang e le sodium X mofuta oa molek'hule sieve, ke alkali metal silicaluminate, e na le alkaline e itseng, ke ea sehlopha sa metheo e tiileng.
