E like me kā mākou e ʻike ai, loaʻa nā ʻano like ʻole o ka polyacrylamide i nā ʻano like ʻole o ka mālama ʻana a me nā hopena like ʻole. No laila ʻo ka polyacrylamide nā ʻāpana keʻokeʻo āpau, pehea e ʻike ai i kāna kumu hoʻohālike?
Aia 4 mau ala maʻalahi e hoʻokaʻawale i ke ʻano o ka polyacrylamide:
1. Ua ʻike mākou a pau ʻo ka cationic polyacrylamide ka mea kūʻai nui loa ma ka mākeke, a ukali ʻia e ka polyacrylamide non-ionic, a ma hope o ka anionic polyacrylamide. Mai ke kumukūʻai, hiki iā mākou ke hana i kahi hoʻoholo mua ma ke ʻano ion.
2. E hoʻonā i ka polyacrylamide e ana i ka waiwai pH o ka hopena. ʻOkoʻa nā koina pH o nā ʻano hoʻohālike like ʻole.
3. ʻO ka mea mua, e koho i nā huahana anionic polyacrylamide a me ka cationic polyacrylamide, a hoʻoheheʻe iā lākou i kahi kaʻawale. E hoʻohui i ka hopena huahana polyacrylamide e hoʻāʻo ʻia me nā hopena PAM ʻelua. Inā hana ia me ka huahana anionic polyacrylamide, ʻo ia hoʻi he cationic ka Polyacrylamide. Inā hana ia me nā cations, hōʻike ia he anionic a i ʻole ka ionic ka huahana PAM. ʻO ka hemahema o kēia ʻano, ʻaʻole hiki ke hoʻomaopopo pololei inā he anionic a i ʻole polyacrylamide ka huahana. Akā, hiki iā mākou ke hoʻoholo mai ko lākou manawa hoʻopau ʻana, ʻoi aku ka wikiwiki o nā anion ma mua o nā non-ions. ʻO ka maʻamau, hoʻopau loa ka anion i hoʻokahi hola, ʻoiai ʻo ka non-ion e lawe i hoʻokahi hola a me ka hapa.
4. Ma muli o nā hoʻokolohua wai, ʻike mākou a pau he kūpono ka polyacrylamide cationic polyacrylamide PAM maʻamau no nā mea i hoʻopaʻa ʻia i hoʻopaʻa ʻia me nā mea kūlohelohe; He kūpono ka PAM anionic no ka hoʻonui ʻana o nā mea i hoʻopaʻa ʻia a me nā ʻāpana i hoʻopaʻa ʻia. He kūpono ka PAM non-ionic polyacrylamide no ka hoʻokaʻawale ʻana i nā mea paʻa i hoʻokuʻu ʻia i loko o kahi ʻano hui ʻia o ka organik a me ka inorganic, a ʻo ka hopena he acidic a kū ʻole paha. ʻO nā flocs i hanaʻia e ka cationic polyacrylamide he nui a he nui, aʻo nā flocs i hanaʻia e ka anion a me ka non-ion he liʻiliʻi a helelei.
