Alumina Whakahohe mō te Maimoatanga Wai
Whakataki Hua
He rauemi porowhita mā te hua, he āhua porowhita, ā, kāore he paitini, kāore he kakara, kāore e rewa i roto i te wai me te etanoru. He ōrite te rahi o te matūriki, he maeneene te mata, he kaha te kaha miihini, he kaha te mimiti i te makuku, ā, kāore te pōro e pakaru i muri i te mimiti i te wai.
Ko te rahi o te matūriki he 1-3mm, 2-4mm/3-5mm, he iti iho rānei pērā i te 0.5-1.0mm. He nui ake te horahanga whakapā ki te wai, ā, he nui ake i te 300m²/g te horahanga mata motuhake, he nui ake i te 300m²/g te nui o ngā moroiti, ā, ka taea te whakarite kia kaha te mimiti me te nui o te tango fluorination ki te fluorinnion i roto i te wai.
He maha ngā awaawa kapia o te alumina mō te hauwai waikura, ā, he whānui te horahanga o te mata, ka taea te whakamahi hei ngongo, hei whakamaroke, hei whakakorikori hoki. I taua wā anō, ka whakatauhia hoki i runga i te āhua o te matū e ngongohia ana. He kaha tōna hononga ki te wai, ki ngā waikura, ki te waikawa acetic, ki te kawakore, me ētahi atu. Ko te alumina whakahohe he momo whakamaroke hohonu wai-iti, he ngongo hoki hei ngongo i ngā ngota kapia.
I raro i ētahi āhuatanga whakahaere me ngā āhuatanga whakaora, ko tōna hohonutanga whakamaroke he rite ki te pāmahana tomairangi i raro iho i te -40℃, ā, he mea whakamaroke pai mō te whakamaroke hohonu i te wai iti. He whānuitia te whakamahinga i roto i te whakamaroke hau me te wai o te ahumahi petrochemical, te whakamaroke o te ahumahi kakahu, te ahumahi whakaputa hāora me te hau aunoa, te mimiti pēhanga i roto i te ahumahi wehenga hau, me ētahi atu. Nā te wera kupenga teitei o te paparanga mimiti monomolecular, he tino pai mō ngā taputapu whakaora kore wera. Ko te Alumina mō te hauwai peroxide he matūriki porowhita ma me te rahi matūriki ōrite, he mata maeneene, he kaha miihini teitei me te kaha hygroscopicity. He mea hanga ki te alumina parakore teitei mā te whakarite pūtaiao me te whakaotinga catalytic. Ka taea te whakamahi hei tango fluoride mō te wai fluoride teitei, ka waiho hei adsorbent ngota me te horahanga mata motuhake nui. Ina iti te uara pH me te kawakore o te wai mata, he teitei te kaha tango fluorine, neke atu i te 3.0mg/g. Ka taea te whakamahi mō te tango fluorine, te tango arsenic, te tango tae paru me te tango haunga o te wai inu me ngā taputapu ahumahi.

Te tono/te tākai
Ka taea te whakamahi hei tango i te āteneki mō te wai. Ina koa he takitahi te uara PH me te kawakore o te wai, ka taea e te nui o te tango i te āteneki te neke ake i te 4.0mg/g. Ka taea te whakamahi hei tango i te āteneki i roto i te wai inu.
Pēke whatu 25kg/pahu pepa 25kg/pahu rino 200L, i runga rānei i te tono a te kiritaki.
