Polyacrylamide
Ko te Polyacrylamide he polymer raina, ko te hua ka wehea ki te puehu maroke me te rua o nga momo colloidal. E ai ki te taumaha o te taumaha o te ngota ngota, ka taea te wehea ki te taumaha ngota iti (<1 miriona), te taumaha o te ngota o te ngota (2 ~ 4 miriona) me te taumaha nui o te ngota (> .7 miriona). E ai ki tona hanganga ka taea te wehewehe ki te kore - katote, anion me te cationic. Te wehenga o te wai (HPAM) o te momo anion. Ko te mekameka matua o te polyacrylamide he maha nga roopu amide, he nui nga mahi matū, a ka taea te whakarereke kia hua ai te tini o te polyacrylamide. Ko nga hua kua whakamahia whānuitia i roto i te mahi pepa, te tukatuka kohuke, te tango hinu, te miihini metara, nga taonga hanga, te mahi paraka wai me etahi atu umanga. Hei whakahinuhinu, kaihoko whakatārewatanga, whakapakarehu paru, kaihoko whakakapinga hinu, ngaronga whakaheke wai me te kaihoko whakakao, kua whakamahia whanui te polyacrylamide ki te keri, te waikawa, te pakaru, te whakapiri wai, te raima, te whakaoranga hinu tuarua me te whakaora hinu hou.

Tono
1. te taatai me te taatai i te maimoatanga wai waipiro
Ma te taarua me te taatai te waipiro waipiro, hei utu mo nga kohinga iti o te ngota ngota iti, e pa ana ki te waahanga nui o te koopu, he nui te kaha o te kohinga, he tino pai nga tikanga ph e whai ake nei: 8.0.
2.Papermaking maimoatanga waikore
Ko te maimoatanga mo te horoi waipiro papermaking, e whakamahia ana hei coagulant hei utu mo te polyaluminum pūhaumāota, konumohe pūkawa ngāwha, me ētahi atu, ka taea hoki te whakamahi hei whakaheke i te paru paru.
