3A kānana molekula

ʻO 3A molecular sieve he alkali metala aluminate, i kekahi manawa ua kapa ʻia ʻo 3A zeolite molecular sieve.

inoa Pelekane: 3A Molecular Sieve
Lakiō Silica / alumini: SiO2/ Al2O3≈2
Ka nui pore kūpono: ma kahi o 3A (1A = 0.1nm)

ʻO ka loina hana o ka molecular sieve ka mea nui e pili ana i ka nui o ka pore o ka sieve molecular, i kēlā me kēia 0.3nm / 0.4nm / 0.5nm, hiki iā lākou ke adsorb i nā molekele kinoea nona ka liʻiliʻi o ka molecular diameter ma mua o ka nui o ka pore, a ʻoi aku ka nui o ka nui o ka pore. nui ka mana adsorption.ʻOkoʻa ka nui o ka puka, a ʻokoʻa nā mea kānana.Ma nā ʻōlelo maʻalahi, hiki i ka 3a molecular sieve ke hoʻopili wale i nā molekala ma lalo o 0.3nm.

3A molecular kānana he pore nui o 3A, ka mea nui i hoʻohana 'ia no ka adsorb wai, a aole adsorb kekahi mole me ke anawaena oi aku mamua o 3A.E like me nā hiʻohiʻona o ka noi ʻoihana, ʻo ka molecular sieve ka wikiwiki adsorption wikiwiki, nā manawa hou, ka ikaika ʻoki a me ka hiki ke anti-pollution, e hoʻomaikaʻi i ka hoʻohana pono ʻana o ka sieve molecular a hoʻonui i ke ola lawelawe o ka sieve molecular.He mea pono adsorption no ka maloʻo hohonu, hoʻomaʻemaʻe a me ka polymerization o ke kinoea-wai i loko o ka ʻaila a me ka ʻoihana kemika.
