Polyacrylamide(PAM), hei matū whakapūkara polymer e whakamahia whānuitia ana, e whakamahia whānuitia ana i roto i ngā momo maimoatanga paru. Heoi, he maha ngā kaiwhakamahi kua taka ki roto i ētahi hē i te wā o te whiriwhiri me te whakamahinga. Ko te whāinga o tēnei tuhinga he whakaatu i ēnei hē me te hoatu i ngā māramatanga me ngā whakaaro tika.
Te Mārama Hē 1: Ka nui ake te taumaha ngota ngota, ka nui ake te whai huatanga o te flocculation.
I te wā e whiriwhiri ana i te polyacrylamide, he tokomaha te hunga e whakaaro ana me nui ake te pai o te flocculation o te tauira he nui ake te taumaha ngota. Engari ko te mea pono, he rau ngā tauira o te polyacrylamide, e tika ana mō ngā āhuatanga kounga wai rerekē. He rerekē te āhua o te wai para e whakaputaina ana e ngā wheketere i ngā ahumahi rerekē. He tino rerekē te uara pH me ngā poke motuhake o ngā kounga wai rerekē. Tērā pea he waikawa, he kawakore, he kūpapa, he hinu rānei, he mea rauropi, he tae, he paru, me ētahi atu. Nō reira, he uaua ki te whakatutuki i ngā hiahia maimoatanga wai para e te momo polyacrylamide kotahi. Ko te huarahi tika ko te tīpako tuatahi i te tauira mā roto i ngā whakamātautau, kātahi ka whakahaere i ngā whakamātautau mīhini hei whakatau i te horopeta tino pai hei whakatutuki i te hua tino whai hua.
Te Mārama Hē 2: Ko te teitei ake o te kukū whirihoranga, ko te pai ake
I te wā e whakarite ana i ngā otinga polyacrylamide, he tokomaha ngā kaiwhakamahi e whakapono ana ko te teitei ake o te kukū, ko te pai ake o ngā āhuatanga flocculation. Heoi, kāore tēnei tirohanga i te tika. Inaa, me whakatau te kukū o te whirihoranga PAM i runga i ngā āhuatanga motuhake o te paru me te waipara. I te nuinga o te wā, he pai ngā otinga PAM me te kukū o te 0.1%-0.3% mō te flocculation me te sedimentation, ko te kukū mō te tango wai paru ā-tāone me te ahumahi he 0.2%-0.5%. Mēnā he nui rawa ngā poke i roto i te waipara, me whakanui ake pea te kukū o te PAM. Nō reira, me whakatau te kukū whirihoranga tika mā roto i ngā whakamātautau i mua i te whakamahinga kia pai ai te pānga whakamahinga.
Te Mārama Hē 3: Ka roa ake te wā e whakarewahia ai, e whakaohokia ai, ka pai ake
He matūriki tioata mā te polyacrylamide me whakarewa katoa kia pai ai te hua. He maha ngā kaiwhakamahi e whakaaro ana, ko te roa o te wā whakarewa me te whakaoho, ko te pai ake, engari ehara i te mea pēnā. Ki te roa rawa te wā whakaoho, ka pakaru te mekameka ngota PAM, ā, ka pā ki te mahi whakapūkara. I te nuinga o te wā, kaua e iti iho i te 30 meneti te wā whakarewa me te whakaoho, ā, me whakaroa kia tika ina iti te pāmahana i te takurua. Ki te poto rawa te wā whakarewa me te whakaoho, e kore e tino memeha te PAM, ā, ka kore e taea te tere o te whakapūkara i roto i te paru. Nō reira, me whakarite e ngā kaiwhakamahi he nui te wā whakarewa me te whakaoho i te wā e whakamahia ana hei whakarite i te pānga whakapūkara o te PAM.
Te Mārama Hē 4: Ko te Ionicity/te nekehanga Ionic anake te pūtake mō te kōwhiringa
Hei tētahi o ngā tohu nui o te polyacrylamide, ko te ionicity e pā ana ki te utu ionic kino me te pai me tōna kiato utu. He maha ngā tāngata e aro nui ana ki te ionicity i te wā e hoko ana, e whakaaro ana ko te teitei ake ko te pai ake. Engari ko te mea pono, ko te nui o te ionicity e pā ana ki te rahi o te taumaha ngota. Ko te teitei ake o te ionicity, ko te iti ake o te taumaha ngota, ā, ko te teitei ake o te utu. I roto i te tukanga whiriwhiri, hei tāpiri atu ki te ionicity, me whai whakaaro ki ētahi atu āhuatanga, pērā i ngā āhuatanga kounga wai motuhake, ngā whakaritenga mō te pānga flocculation, me ētahi atu. Nō reira, kāore e taea te whiriwhiri i te tauira i runga i te nui o te ionization anake. Me whakamātautau anō hei whakatau i te tauira e hiahiatia ana.
Heimea whakapūkara, he mea nui te mahi a te polyacrylamide i roto i te umanga maimoatanga wai. Mēnā me whiriwhiri e koe ngā whakaritenga e tika ana māu, tēnā whakapā mai ki ahau.
