3 Sieve ya molekyulu

3Sieve ya molekyulu ndi aluminiyamu yachitsulo ya alkali, nthawi zina imatchedwanso 3A zeolite molecular sieve.

Dzina la Chingerezi: 3A Molecular Sieve
Chiŵerengero cha silika / aluminiyamu: SiO2/ Al2O3≈2
Kukula kwa pore: pafupifupi 3A (1A = 0.1nm)

Mfundo yogwirira ntchito ya sieve ya maselo imagwirizana kwambiri ndi kukula kwa pore ya sieve ya maselo, motsatana 0.3nm/0.4nm/0.5nm, imatha kutsatsa ma molekyulu a mpweya omwe ma molekyulu ake ndi ang'onoang'ono kuposa kukula kwa pore, ndipo kukula kwake kokulirapo, kukula kwa adsorption. Kukula kwa kabowo ndi kosiyana, ndipo zinthu zosefedwa ndizosiyana. M'mawu osavuta, 3a molekyulu sieve imatha kutsatsa mamolekyu omwe ali pansi pa 0.3nm.

3Sieve ya molekyulu imakhala ndi pore kukula kwa 3A, komwe kumagwiritsidwa ntchito kwambiri kutsatsa madzi, ndipo sikutsatsa molekyulu iliyonse yokhala ndi m'mimba mwake kuposa 3A. Malinga ndi mawonekedwe a mafakitale, sieve ya ma molekyulu imakhala ndi liwiro lothamanga, nthawi yosinthika, kuphwanya mphamvu komanso mphamvu yolimbana ndi kuipitsidwa, zomwe zimapangitsa kuti sieve yama cell ikhale yothandiza komanso imakulitsa moyo wautumiki wa sieve ya maselo. Ndi zofunika adsorption zakuthupi kuya kuyanika kwambiri, kuyenga ndi polymerization wa gasi-zamadzimadzi gawo mu mafuta ndi makampani mankhwala.
