Alumina i ho'ā 'ia no ka mālama wai
Hoʻolauna Huahana
ʻO ka huahana he mea keʻokeʻo, spherical porous mea me ka waiwai o ka non-toxic, odorless, insoluble i ka wai a me ka ethanol.He ʻano like ka nui o ka ʻāpana, maʻemaʻe ka ʻili, kiʻekiʻe ka ikaika mechanical, ikaika ka hiki o ka hoʻoheheʻe ʻana i ka wai a ʻaʻole i māhele ʻia ka pōleʻa ma hope o ka lawe ʻana i ka wai.
Hiki ke 1-3mm, 2-4mm/3-5mm, a i ʻole ka liʻiliʻi e like me 0.5-1.0mm. ʻOi aku ka nui o ka hoʻopili ʻana me ka wai a me kahi ʻāpana kikoʻī ma mua o 300m²/g. microspores a hiki ke hōʻoia i ka adsorption ikaika a me ka nui defluorination kiʻekiʻe i ka fluorinnion i ka wai.
ʻO ka alumina no ka hydrogen peroxide he nui nā kaila capillary a me kahi ākea nui, hiki ke hoʻohana ʻia e like me adsorbent, desiccant a me catalyst.I ka manawa like, ua hoʻoholo ʻia e like me ka polarity o ka mea adsorbed.He pilina ikaika kona no ka wai, oxides, acetic acid, alkali, etc. Activated alumina he ʻano micro-water deep desiccant a me ka adsorbent no ka adsorbing polar mole..
Ma lalo o kekahi mau kūlana hana a me nā kūlana hana hou, ʻo kona hohonu maloʻo e like me ke kiʻekiʻe o ka mahana o ka hau ma lalo o -40 ℃, a he desiccant maikaʻi ia no ka hoʻomaloʻo hohonu ʻana i ka wai.Hoʻohana nui ʻia ia i loko o ke kinoea a me ka wai o ka hoʻomaloʻo ʻana i ka ʻoihana petrochemical, ka maloʻo ʻana o ka ʻoihana textile, ka ʻoihana hana oxygen a me ka ea mea kani ʻakomi, adsorption kowali kaomi i ka ʻoihana hoʻokaʻawale ea, a me nā mea ʻē aʻe. He kūpono loa ia no nā mea hana hou ʻole wela.ʻO ka alumina no ka hydrogen peroxide he mau ʻāpana porous spherical keʻokeʻo me ka nui o nā ʻāpana like ʻole, ka ʻili laulima, ka ikaika mechanical kiʻekiʻe a me ka hygroscopicity ikaika.Hana ʻia ia me ka alumina maʻemaʻe kiʻekiʻe ma o ka hoʻomākaukau ʻepekema a me ka hoʻopau catalytic.Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohemo fluoride no ka wai fluoride kiʻekiʻe, e hoʻolilo iā ia i adsorbent molecular me kahi ʻāpana kikoʻī nui.Ke haʻahaʻa ka pH waiwai a me ka alkalinity o ka wai maka, ʻoi aku ka nui o ka hiki ke hoʻoneʻe fluorine, ʻoi aku ma mua o 3.0mg/g.Hiki ke hoʻohana ʻia no ka wehe ʻana i ka fluorine, ka wehe ʻana i ka arsenic, ka decolorization a me ka deodorization o ka wai inu a me nā mea hana ʻoihana.

Noi/Pake
Hiki ke hoʻohana ʻia e like me ka defluorination agent no ka wai.ʻOi aku ka lōʻihi o ka waiwai PH a me ka alkalinity o ka wai, ʻoi aku ka nui o ka defluorination ma luna o 4.0mg/g.Hiki ke hoʻohana ʻia e wehe i ka arsenic i ka wai inu.
25kg i ulana ʻeke / 25kg pepa pahu pahu / 200L pahu hao a i ʻole ke noi a ka mea kūʻai aku.
