Alumina Whakahohehia mo te maimoatanga wai
Whakataki Hua
Ko te hua he ma, he mea porohita porohita me te taonga o te kore-paitini, te hongi, te kore e rewa i te wai me te waihano. He rite te rahi o te matūriki, he maeneene te mata, he teitei te kaha o te miihini, he kaha te kaha o te makuku makuku, a, kaore e pakaruhia te poi i muri i te tango i te wai.
Ko te rahi o te waahanga ko te 1-3mm, 2-4mm/3-5mm, he iti ake ranei penei i te 0.5-1.0mm. He nui ake te waahi whakapiri ki te wai me te waahanga mata motuhake teitei ake i te 300m²/g, he nui te rahi microspores a ka taea te whakarite i te kaha o te whakaurunga me te nui o te defluorination rōrahi ki te fluorinnion i roto i te wai.
Ko te konumohe mo te hauwai peroxide he maha nga hongere capillary me te waahi mata nui, ka taea te whakamahi hei adsorbent, desiccant me te whakakorikori. I te wa ano, ka whakatauhia ano kia rite ki te polarity o te matū adsorbed. He hononga kaha mo te wai, te waikura, te waikawa acetic, te kawakawa, me etahi atu. Ko te alumina whakahohe he momo moroiti-wai te whakamaroke hohonu me te adsorbent mo te adsorbing ngota polar. .
I raro i etahi tikanga whakahaere me nga tikanga whakahou, ko tona hohonutanga whakamaroke he rite ki te teitei o te haupapa i raro -40 ℃, he mea whakamaroke pai mo te whakamaroke hohonu o te wai. Kei te whānui whakamahia te reira i roto i te hau me te wai whakamaroke wāhanga o te ahumahi petrochemical, whakamaroke o te ahumahi pueru, ahumahi production hāora me te rangi taputapu aunoa, pēhanga piu adsorption i roto i te ahumahi wehenga rangi, me ētahi atu Na te wera kupenga tiketike o te paparanga adsorption monomolecular, te reira. he tino pai mo nga taputapu whakaora kore wera. Ko te konumohe mo te hauwai peroxide he matūriki porohita porowhita ma me te rahi o te matūriki rite, te mata maeneene, te kaha miihini me te hygroscopicity kaha. He mea hanga ki te konumohe tino parakore na roto i te whakareri putaiao me te whakaoti catalytic. Ka taea te whakamahi hei tango i te fluoride mo te wai fluoride teitei, ka waiho hei whakangao ngota ngota me tetahi waahanga mata motuhake. Ina he iti te uara pH me te kawakore o te wai mata, he nui te kaha o te tango fluorine, nui atu i te 3.0mg/g. Ka taea te whakamahi mo te tango i te fluorine, te tango arsenic, te whakahekenga parakaingaki me te whakakore i te wai inu me nga taputapu ahumahi.

Taupānga/Pake
Ka taea te whakamahi hei kaihoko whakaheke mo te wai. Ina koa he mokemoke te uara PH me te alkalinity o te wai, ka nui ake te 4.0mg/g te rōrahi defluorination. Ka taea te whakamahi ki te tango arsenic i roto i te wai inu.
25kg peeke raranga / 25kg pepa papa pahū / 200L pahū rino ranei ia tono a te kiritaki.
