3A Anana Molekala
-
ʻO ka waiʻona waiʻona i loko o ka hale kiaʻi hoʻomaʻemaʻe/desiccant/adsorbent/hollow glass molecular sieve
Molecular sieve 3A, i ʻike ʻia hoʻi he molecular sieve KA, me ka puka o kahi 3 angstroms, hiki ke hoʻohana ʻia no ka hoʻomaloʻo ʻana i nā kinoea a me nā wai e like me ka dehydration o hydrocarbons.Hoʻohana nui ʻia ia no ka hoʻomaloʻo piha ʻana o ka petrol, nā kinoea i haki, ethylene, propylene a me nā kinoea maoli.
ʻO ke kumu hana o nā kānana molekala e pili nui ana i ka nui o ka pore o nā kānana molekala, ʻo ia ka 0.3nm / 0.4nm / 0.5nm.Hiki iā lākou ke hoʻopili i nā molekele kinoea nona ka liʻiliʻi o ke anawaena mole ma mua o ka nui o ka pore.ʻO ka nui o ka nui o ka pore, ʻoi aku ka nui o ka hiki ke adsorption.ʻOkoʻa ka nui o ka pore, a ʻokoʻa nā mea i kānana a hoʻokaʻawale ʻia.Ma nā huaʻōlelo maʻalahi, hiki i ka 3a molecular sieve ke hoʻopili wale i nā molekole ma lalo o 0.3nm, 4a molecular sieve, ʻo nā molekala i hoʻopili ʻia e emi iho ma mua o 0.4nm, a ʻo 5a molecular sieve ka like.Ke hoʻohana ʻia ma ke ʻano he desiccant, hiki i kahi sieve molecular ke komo i ka 22% o kona kaumaha ponoʻī i ka makū.
