E mōhio ana tātou katoa, he rerekē ngā momo maimoatanga paru me ngā pānga rerekē o ngā momo polyacrylamide. Nō reira, he mā katoa ngā matūriki o te polyacrylamide, me pēhea te wehewehe i tōna tauira?
E whā ngā huarahi māmā hei wehewehe i te tauira o te polyacrylamide:
1. E mōhio ana tātou katoa ko te polyacrylamide cationic te mea tino utu nui i te mākete, ā, muri iho ko te polyacrylamide kore-ionic, ā, ko te polyacrylamide anionic te mea whakamutunga. Mai i te utu, ka taea e tātou te whakatau tuatahi i te momo ion.
2. Whakarewahia te polyacrylamide hei ine i te uara pH o te otinga. He rerekē ngā uara pH e rite ana o ngā tauira rerekē.
3. Tuatahi, tīpakohia ngā hua polyacrylamide anionic me ngā hua polyacrylamide cationic, ka whakarewahia motuhake. Whakaranua te otinga hua polyacrylamide hei whakamātautau me ngā otinga PAM e rua. Mena ka tauhohe ki te hua polyacrylamide anionic, ko te tikanga he cationic te Polyacrylamide. Mena ka tauhohe ki ngā cations, ka whakaatu he anionic, he kore-ionic rānei te hua PAM. Ko te ngoikoretanga o tēnei tikanga ko te kore e taea te tautuhi tika mena he polyacrylamide anionic, he kore-ionic rānei te hua. Engari ka taea e tātou te whakatau mai i te wā rewa, he tere ake te rewa o ngā anion i ngā non-ions. I te nuinga o te wā, ka rewa katoa te anion i roto i te kotahi haora, ko te non-ion ia e kotahi me te hawhe haora.
4. Mai i ngā whakamātautau paru, e mōhio ana tātou katoa he pai te polyacrylamide cationic polyacrylamide PAM mō ngā mea iri kua whakatārewatia he utu kino kei roto ngā matū waro; he pai te PAM anionic mō te kukū teitei ake o ngā mea iri kua whakatārewatia he utu pai me ngā matūriki iri. He matotoru (0.01-1mm), he koretake, he kawakore rānei te uara pH; he pai te polyacrylamide PAM kore-ionic mō te wehewehe i ngā totoka iri i roto i te āhua whakaranu o te waro me te kore-waro, ā, he waikawa, he koretake rānei te otinga. He nui, he mātotoru hoki ngā flocs i hangaia e te polyacrylamide cationic, ko ngā flocs i hangaia e te anion me te non-ion he iti, he marara.
