Sefa ya 4A molekyulu & sefa ya 13X molekyulu

4A molecular sieve chemical formula: Na₂O·Al₂O₃·2SiO₂·4.5H₂O ₃
Mfundo yogwirira ntchito ya sieve ya molekyulu imagwirizana kwambiri ndi kukula kwa pore ya sieve ya molekyulu, yomwe imatha kuyamwa mamolekyu a mpweya omwe mainchesi ake ndi ochepa kuposa kukula kwa pore, ndipo kukula kwa pore kukakhala kwakukulu, mphamvu ya kuyamwa imakulanso. Kukula kwa malo otseguka ndi kosiyana, ndipo zinthu zosefedwa ndizosiyana. 4a sieve ya molekyulu, mamolekyu otsekedwa ayeneranso kukhala ochepera 0.4nm
Ma sieve a 4A molecular amagwiritsidwa ntchito makamaka poumitsa mpweya wachilengedwe ndi mitundu yosiyanasiyana ya mpweya wa mankhwala ndi zakumwa, ma refrigerant, mankhwala, deta yamagetsi ndi zinthu zosinthasintha, kuyeretsa argon, ndikulekanitsa methane, ethane ndi propane. Amagwiritsidwa ntchito makamaka poumitsa kwambiri mpweya ndi zakumwa monga mpweya, mpweya wachilengedwe, ma hydrocarbon ndi ma refrigerant; Kukonzekera ndi kuyeretsa argon; Kuumitsa mosasunthika kwa zigawo zamagetsi ndi zinthu zomwe zimatha kuwonongeka; Zothandizira kuuma mu utoto, ma polyester, utoto ndi zokutira.

Sieve ya molekyulu ya mtundu wa 13X, yomwe imadziwikanso kuti sieve ya molekyulu ya mtundu wa sodium X, ndi silicaluminate yachitsulo cha alkali, yokhala ndi alkaline inayake, ndi ya gulu la maziko olimba.
Fomula yake ya mankhwala ndi Na2O· Al2O3·2.45SiO2·6.0H20,
Kukula kwa ma pore ake ndi 10A ndipo amayamwa molekyulu iliyonse yoposa 3.64A ndi yochepera 10A
13x imagwiritsidwa ntchito kwambiri mu:
1) Kuyeretsa mpweya mu chipangizo cholekanitsa mpweya kuti muchotse madzi ndi carbon dioxide.
2) Kuumitsa ndi kusungunula mpweya wachilengedwe, mpweya wa petroleum wosungunuka ndi ma hydrocarbon amadzimadzi.
3) Kuumitsa kwa mpweya wozama. Sieve ya molekyulu ya mtundu wa 13X, yomwe imadziwikanso kuti sieve ya molekyulu ya mtundu wa sodium X, ndi silicaluminate yachitsulo cha alkali, yokhala ndi alkaline inayake, ndi ya gulu la maziko olimba.

Kukula kwa ma pore ake ndi 10A ndipo amayamwa molekyulu iliyonse yoposa 3.64A ndi yochepera 10A
13x imagwiritsidwa ntchito kwambiri mu:

2) Kuumitsa ndi kusungunula mpweya wachilengedwe, mpweya wa petroleum wosungunuka ndi ma hydrocarbon amadzimadzi.
3) Kuumitsa mpweya wonse.
