Pehea e hoʻoholo ai i ke ʻano o ka polyacrylamide

E like me kā kākou e ʻike nei, he ʻokoʻa nā ʻano hana wai ʻino o nā ʻano polyacrylamide like ʻole a me nā hopena like ʻole. No laila, he mau ʻāpana keʻokeʻo nā polyacrylamide āpau, pehea e hoʻokaʻawale ai i kāna kumu hoʻohālike?

Aia he 4 mau ala maʻalahi e hoʻokaʻawale ai i ke kumu hoʻohālike o ka polyacrylamide:

1. Ua ʻike mākou a pau ʻo ka polyacrylamide cationic ka mea pipiʻi loa ma ka mākeke, ukali ʻia e ka polyacrylamide non-ionic, a ʻo ka polyacrylamide anionic hope loa. Mai ke kumukūʻai, hiki iā mākou ke hana i kahi hoʻoholo mua ma ke ʻano ion.

2. E hoʻoheheʻe i ka polyacrylamide e ana i ka waiwai pH o ka hopena. He ʻokoʻa nā waiwai pH like o nā ʻano hoʻohālike like ʻole.

3. ʻO ka mea mua, koho i nā huahana polyacrylamide anionic a me nā huahana polyacrylamide cationic, a hoʻoheheʻe iā lākou i kahi kaʻawale. E kāwili i ka hopena huahana polyacrylamide e hoʻāʻo ʻia me nā hopena PAM ʻelua. Inā pane ia me ka huahana polyacrylamide anionic, ʻo ia hoʻi he cationic ka Polyacrylamide. Inā pane ia me nā cations, hōʻoia ia he anionic a non-ionic paha ka huahana PAM. ʻO ka hemahema o kēia ʻano hana, ʻaʻole hiki ke ʻike pololei inā he anionic a non-ionic polyacrylamide paha ka huahana. Akā hiki iā mākou ke hoʻoholo mai ko lākou manawa hoʻoheheʻe, hoʻoheheʻe wikiwiki nā anions ma mua o nā non-ions. Ma keʻano laulā, ua hoʻoheheʻe loa ʻia 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 ʻino, ʻike mākou a pau he kūpono ka polyacrylamide cationic polyacrylamide PAM maʻamau no nā mea i hoʻopiʻi ʻia me nā mea organik; kūpono ka anionic PAM no ka nui o ka nui o nā mea i hoʻopiʻi ʻia me nā mea inorganic a me nā ʻāpana i hoʻopiʻi ʻia. ʻO Coarse (0.01-1mm), he kūlike ʻole a alkaline paha ka waiwai pH; kūpono ka non-ionic polyacrylamide PAM no ka hoʻokaʻawale ʻana i nā mea paʻa i hoʻopiʻi ʻia i loko o kahi ʻano hui o nā mea organik a me nā mea inorganic, a he acidic a kūlike ʻole paha ka hopena. He nui a paʻa nā flocs i hoʻokumu ʻia e ka cationic polyacrylamide, ʻoiai he liʻiliʻi a hoʻopuehu ʻia nā flocs i hoʻokumu ʻia e ka anion a me ka non-ion.
