Tohu

Ko te Polyacrylamide he polymer raina, ka wehea te hua ki te paura maroke me nga momo colloidal e rua. E ai ki tona taimaha ngota toharite, ka taea te wehewehea ki te iti o te taumaha ngota (<1 miriona), te taumaha ngota reo (2 ~ 4 miriona) me te taumaha ngota teitei (>.7 miriona). - katote, anion me te cationic. Te whakakore i te wai (HPAM) o te momo anion. Kei roto i te mekameka matua o te polyacrylamide te maha o nga roopu amide, me te mahi matū nui, ka taea te whakarereke ki te whakaputa i nga hua maha o te polyacrylamide. Ko nga hua kua whakamahia nuitia i roto i te hanga pepa, te tukatuka kohuke, te tango hinu, te whakarewa, te hanga whare, te maimoatanga parakaingaki me etahi atu ahumahi. Ka rite ki te whakahinuhinu, te kaihoko whakatārewatanga, te whakapumau paru, te kaihoko whakaheke hinu, te kaihoko whakaheke wai me te kaihoko matotoru, kua whakamahia nuitia te polyacrylamide i roto i te keri, te waikawa, te pakaru, te whakakii wai, te raima, te whakaora hinu tuarua me te whakaora hinu tuatoru.

Taupānga

1. te ta me te tae ki te maimoatanga wai para

Ko te ta me te tae ki te maimoatanga wai para, hei utu mo nga whakangao ngota ngota iti tuku iho, e pa ana ki te inenga nui tuku iho o te coagulant, he tiketike te pai o te coagulation, nga tikanga ph tino pai e whai ake nei: 8.0.

2.Papermaking maimoatanga wai para

Ko te maimoatanga wai para pepa, e whakamahia ana hei kaitao hei utu mo te polyaluminum chloride, konumohe sulfate, me etahi atu, ka taea hoki te whakamahi hei whakamaoritanga o te paru hanga pepa.
