Te Polyacrylamide (PAM) me tōna whakamahinga i roto i te maimoatanga wai
Ko te whakahaere me te whakahaere i te parahanga wai he wāhanga nui o te tiaki taiao, ā, ko te whakakorenga wai para he mea nui kia nui haere te aro atu.
He mea tino nui te mahi a te Polyacrylamide (PAM) i roto i te mara o te maimoatanga wai nā te taumaha ngota teitei, te wairewa-wai, te whakahaere i te taumaha ngota me ngā whakarerekētanga mahi.
Ka taea te whakamahi i te PAM me ōna hua hei whakapūkara whai hua, hei whakamātotoru, hei whakaiti tō, ā, e whakamahia whānuitia ana i roto i te tukatuka wai, te hanga pepa, te hinu, te waro, te matawhenua, te hanga me ētahi atu rāngai ahumahi.
I roto i te wai whenua, te wai mata me te waipara, he maha ngā matūriki e noho ana i roto i ngā paru me ngā poke, he iti rawa te rahi, ā, he iti rawa te kaha ki te tau i raro i te kaha ā-papa. Nā te mea kāore i taea e te oneone te whakatutuki i ngā whakaritenga, mā te āwhina o ngā matū ka tere ake te taunga o te wai, kua whakamahia te hangarau ki te whakaputa. Hei tauira, ka mimiti te ngota PAM i ētahi matūriki, ā, ka nui ake te putunga wai, nō reira ka tere ake te taunga o ngā matūriki.
Ki te whakatauritea ki te mea whakapūkara kore-ora, he maha ngā painga nui o te PAM: he maha ngā momo mō ngā āhuatanga rerekē, he pai te mahi, he iti te horopeta, he iti te paru e puta ana, he ngāwari te tukatuka i muri i te mahi. Nā tēnei ka waiho koia te mea whakapūkara tino pai.
Ko te horopeta o te matū whakakōkī kore-waro he 1/30 ki te 1/200.
E rua ngā āhua matua e hokona ana te PAM: te paura me te whakaemulsion.
He ngāwari te kawe i te paura PAM, engari ehara i te mea ngāwari ki te whakamahi (me whakamahi taputapu whakarewa), ko te whakarewa ia he uaua ki te kawe, ā, he poto ake te roa o te rokiroki.
He nui te wairewatanga o te PAM ki te wai, engari he puhoi rawa te wairewa. He maha ngā hāora, he pō rānei te roa o te wairewatanga. Mā te whakaranu pai o te mīhini ka āwhina i te wairewatanga o te PAM. Tāpirihia mārire tonu te PAM ki te wai kua whakaohokia - kaua ki te wai ki te PAM.
Ka taea e te whakamahana te whakanui ake i te tere memeha, engari kaua te pāmahana e neke ake i te 60°C.
Ko te kukū PAM teitei rawa o te otinga polymer he 0.5%, ka taea te whirihora i te kukū o te PAM ngota iti ki te 1%, ki runga ake rānei.
Me whakamahi te otinga PAM kua oti te whakarite i roto i ētahi rā, ki te kore ka pāngia te mahi o te whakapūkara.
