3Shandho molecular

3A shaandho molecular waa aluminate bir alkali ah, mararka qaarkood waxaa sidoo kale loo yaqaan 3A zeolite shaandho molecular.

Magaca Ingiriisiga: 3A Molecular Sieve
Silica / aluminium saamiga: SiO2 / Al2O3≈2
Cabbirka daloolka waxtarka leh: qiyaastii 3A (1A = 0.1nm)

Mabda'a shaqada ee shaandho molecular inta badan waxay la xiriirtaa cabbirka daloolka shaandhada molecular, siday u kala horreeyaan 0.3nm/0.4nm/0.5nm, waxay ku milmi karaan molecules gaaska kuwaas oo dhexroorkoodu ka yar yahay cabbirka daloolka, iyo cabbirka daloolka weyn, weynaanta awoodda adsorption. Baaxadda daloolku waa kala duwan yahay, waxyaabaha la sifeeyayna way kala duwan yihiin. Erayada fudud, 3a shaandho molecular kaliya waxay soo saari kartaa molecules ka hooseeya 0.3nm.

3 Shaandhooyin molecular waxay leedahay cabbir dalool ah oo ah 3A, taas oo inta badan loo isticmaalo in lagu dhufto biyaha, oo aan soo dhejin wax molecule leh dhexroor ka weyn 3A. Marka loo eego sifooyinka codsiga warshadaha, shaandhada molecular waxay leedahay xawaare xayaysiis ah oo degdeg ah, waqtiyada dib-u-soo-nooleynta, burburinta xoogga iyo awoodda wasakheynta, taas oo hagaajinaysa waxtarka isticmaalka shaandhada molecular waxayna kordhisaa nolosha adeegga shaandhada molecular. Waa qalab lagama maarmaan u ah qalajinta qoto dheer, sifaynta iyo polymerization ee wejiga dareeraha gaaska ee batroolka iyo warshadaha kiimikada.
