He aha te Polyaluminium Chloride?
Ko te Polyaluminium chloride, e whakarāpopototia ana ko te PAC, he matū rongoā wai polymer kore-waro. E rua ngā momo: te whakamahinga wai inu ā-whare me te whakamahinga wai inu kore-whare, ia momo e pā ana ki ngā paerewa rerekē. E rua ngā momo āhua: te wai me te totoka. Nā te rerekētanga o ngā wāhanga kei roto i ngā rauemi mata, he rerekē te tae āhua me ngā pānga tono.
He totoka kore tae, he kōwhai rānei te polyaluminium chloride. He wai mārama, he parauri kōwhai rānei tōna otinga, he ngāwari ki te wairewa ki te wai me te waipiro waimeha, kāore e wairewa ki te waipiro kore wai me te glycerol. Me rongoa ki roto i te whare putunga hauhautanga, hauhautanga, maroke, me te ma. I te wā e kawe ana, me tiaki i te ua me te rā tika, me ārai i te ngawari o te mahi, me te whakahaere me te tupato i te wā e utaina ana, e tangohia ana hei ārai i te kino o te takai. E ono marama te wā rokiroki mō ngā hua wai, ā, kotahi tau mō ngā hua totoka.
Ko ngā rongoā wai e whakamahia ana mō te purenga wai inu, te wai para ahumahi, me ngā wai para o te tāone, pērā i te tango i te rino, te wheowhio, te cadmium, te parahanga irahiko, me te hinu e mānu ana. E whakamahia ana hoki mō te rongoā wai para ahumahi, pērā i te tā me te tae wai para. E whakamahia ana hoki i roto i te whakarewanga tika, te rongoā, te hanga pepa, te rapa, te hanga hiako, te hinu, te ahumahi matū, me ngā tae. E whakamahia ana te polyaluminium chloride hei rongoā wai me te rauemi mata whakapaipai i roto i te rongoā mata.
He āhuatanga mimiti, whakapūmau, whakapūmau me ētahi atu āhuatanga o te polyaluminium chloride. He iti hoki tōna pumau, he paitini, he waikura hoki. Mēnā ka tau ki te kiri, horoia tonutia ki te wai. Me mau ngā kaimahi whakaputa i ngā kākahu mahi, i ngā kopare kanohi, i ngā karapu, me ngā pūtu rapa roa. Me hiri ngā taputapu whakaputa, ā, me pai te hauhautanga o te awheawhe. Ka pirau te polyaluminium chloride ina werahia ki runga ake i te 110 ℃, ka tukuna te hau hauwai chloride, ā, ka pirau hei waikura konumohe; Ka tauhohe ki te waikawa ka heke te polymerization, ka heke te tohu polymerization me te alkalinity, ā, ka huri hei tote konumohe. Mā te taunekeneke ki te alkali ka piki ake te tohu polymerization me te alkalinity, ā, ka hua ake he konumohe hauwai waikawa, he tote aluminate rānei; Ina konatunatua ki te konumohe whanariki, ki ētahi atu tote waikawa maha-valent rānei, ka ngāwari te whakaputa i te ua, ka taea te whakaiti, te ngaro rānei i te mahi coagulation.
