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 e pili nui ana i ka nui o ka pore sieve molecular sieve, kēlā me kēia 0.3nm / 0.4nm / 0.5nm, hiki iā lākou ke adsorb i nā molekele kinoea nona ka liʻiliʻi o ke anawaena mole ma mua o ka nui o ka pore, a ʻoi aku ka nui o ka nui o ka pore, ka 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 sieve he 3A ka nui o ka pore, ka mea i hoʻohana nui ʻia e adsorb i ka wai, ʻaʻole ia e hoʻopili i kekahi mole me ke anawaena oi aku ma mua o 3A. Wahi a nā hiʻohiʻona o ka noi ʻoihana, ʻo ka molecular sieve ka wikiwiki adsorption wikiwiki, ka 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.
