Tirohanga o te alumina whakahohe
Ko te alumina whakahohe, e mohiotia ana ko te bauxite whakahohe, ka kiia ko te alumina whakahohe i te reo Ingarihi. Ko te alumina e whakamahia ana i roto i nga whakakōkī ka kiia ko "konumohe whakahohe". He rauemi totoka maiengi, tino marara me te horahanga mata nui. Ko tona mata microporous nga ahuatanga e hiahiatia ana mo te catalysis, penei i te mahi adsorption, te mahi mata, te tino pai o te waiariki, me etahi atu, na reira ka whakamahia nuitia hei whakakorikori me te kaikawe mo nga tauhohenga matū.
Ko te konumohe whakahohe pehanga piu hinu adsorbent he matūriki porous porohita. Ko te alumina kua whakahohehia he rite te rahi o te matūriki, te mata maeneene, te kaha miihini teitei, te kaha o te hygroscopicity, kaore e pupuhi me te pakaru i muri i te whakauru wai, ka noho tonu. Kore he paitini, he kakara, he kore e rewa ki te wai me te waiwaro.
Konumina
Kare e rewa i roto i te wai, ka taea te memeha i roto i te waikawa sulfuric. Ka taea te whakamahi ki te whakamahine i te konumohe whakarewa, he rauemi mata ano hoki mo te hanga rīwai, porcelain, rauemi whakaahuru me nga kohatu horihori.
Ko te konumohe i whakamahia hei adsorbent, te whakakorikori me te kaikawe kaikawe ka kiia ko "konumohe whakahohe". Kei a ia nga ahuatanga o te porosity, te marara nui me te waahanga mata motuhake. Kei te whakamahia nuitia i roto i te maimoatanga wai, te petrochemical, te matū pai, te koiora me te mara rongoa.
Nga ahuatanga o te alumina
1. He nui te waahanga mata motuhake: ko te alumina whakahohe he nui te waahanga mata motuhake. Ma te whakahaere tika i te punaha sintering o te alumina, ka taea te whakarite i te alumina whakahohe me te waahi mata motuhake e rite ana ki te 360m2 / G. Ko te konumohe kua whakahoahohia ma te whakamahi i te colloidal konumohe hydroxide i whakahoroa e NaAlO2 hei rauemi mata he iti rawa te rahi o te pore me tetahi waahanga mata motuhake ki te 600m2 / g.
2. Te hanganga rahi o te pore ka taea te whakarite: Ko te tikanga, ko nga hua me te rahi o te pore reo ka taea te whakarite ma te tunu ki te konumohe waiwaro parakore. Ka taea te whakarite i nga hua iti o te pore ma te whakarite i te alumina whakahohe me te kapia konumohe, me etahi atu, ka taea te whakarite i te rahi o te pore alumina whakahohe ma te taapiri i etahi matū waro, penei i te ethylene glycol me te muka, i muri i te wera.
3. He waikawa te mata me te pai o te waiariki.
Mahi o te alumina whakahohe
Ko te alumina kua whakahohehia no te waahanga o te konumohe matū, e whakamahia ana i te nuinga o te waa hei adsorbent, hei horoi wai, hei whakakorikori me te kawe kawe. Ko te konumohe whakahohe he kaha ki te whakauru i te wai ki roto i te hau, te kohu wai me etahi wai. Whai muri i te kukū o te whakaurunga, ka taea te whakamahana ki te 175-315. D egree. He maha nga wa ka taea te whakauru me te whakaohooho.
I tua atu i te whakamahia hei whakamaroke, ka taea hoki te tango i te kohu hinu whakahinuhinu mai i te hāora poke, te hauwai, te waro, te hau maori, me etahi atu. Ka taea te whakamahi hei whakakorikori me te tautoko whakakorikori me te tautoko mo te tātari chromatographic.
Ka taea te whakamahi hei kaihoko whakaheke mo te wai inu fluorine teitei (me te kaha whakaheke nui), he kaihoko whakaheke mo te huri i nga alkanes i roto i te hanga o te alkylbenzene, he kaihoko whakaheke me te whakahou mo te hinu whakawhiti, he kaihoko whakamaroke mo te hau i roto i te ahumahi hanga hāora. , ahumahi kakano me te ahumahi hiko, he kaihoko whakamaroke mo te hau taputapu aunoa, me te kaihoko whakamaroke me te kaihoko horoi i roto i te tongi matū, te whakamaroke petrochemical me etahi atu ahumahi.
