ʻO ka hoʻohana ʻana i ka polyacrylamide i ka ʻoihana pepa - ʻO ka mālama ʻana a me nā kōkua wai

ʻO nā huahana i hoʻololi ʻia o ka polyacrylamide i hoʻohana ʻia ma ke ʻano he paʻa a me nā mea hoʻokahe wai i ka hana pepa i hoʻololi pinepine ʻia nā huahana o ka polyacrylamide, me ka anionic polyacrylamide (APAM), cationic polyacrylamide (CPAM) a me amphoteric polyacrylamide (AmPAM), me kahi mole mole pili o 2 miliona ~ 4 miliona. .

ʻO ka maʻamau, hoʻokumu ʻo APAM i kahi ʻōnaehana paʻakikī me nā pūhui cationic ʻē aʻe e pāʻani i kahi hopena kōkua paʻa.No ka laʻana, hiki i ka hui pū ʻana me ka sulfate aluminika hiki ke hoʻopaʻa paʻa ʻia ka APAM me nā fibers, nā fibers maikaʻi, nā mea hoʻopihapiha, a me nā mea ʻē aʻe, a laila e hoʻomaikaʻi nui ai i ka paʻa ʻana o nā fibers a me nā mea hoʻopihapiha.Ka nui o ka noonoo.

ʻO CPAM kekahi o nā mea kōkua paʻa maʻamau i ka hana pepa, a ʻo nā huahana me ke kaumaha molekala kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa e hoʻohana mau ʻia.He kū'ē kona uku i ka fiber, a hiki ke hoʻohana wale ʻia a i hui pū ʻia me ka bentonite, anion, a me nā mea ʻē aʻe, e hoʻoulu ai i ka flocculation o ka pepa ma ke ʻano hoʻopili i loko o ka mea pepa, a hiki ke hoʻonui i ka paʻa ʻana o ka pepa. hoʻopiha pepa a hoʻolaha Hoʻemi ʻia ka neʻe ʻana o ka wai keʻokeʻo ma lalo o ka ʻupena.Ke hoʻohana ʻia ka CPAM a me ka bentonite i hoʻopiʻi maikaʻi ʻole ʻia e hana i kahi ʻōnaehana paʻa a me nā ʻōnaehana kōkua wai, ʻoi aku ka nui o ka nui o nā flocs o ka mea pepa i hana ʻia ma ka hoʻohui ʻana i ka CPAM, a ma hope o ka hoʻokau ʻia ʻana i ka ikaika shear kiʻekiʻe ma hope o ka hele ʻana i ka pulu pulp a. nā mea hana ʻē aʻe, ua wāwahi ʻia nā flocs i nā ʻāpana liʻiliʻi, a ʻo ka hoʻohui ʻana i ka bentonite i hoʻopiʻi maikaʻi ʻia i kēia manawa e hoʻopili hou i nā ʻāpana liʻiliʻi a hana i nā flocs i ʻoi aku ka liʻiliʻi ma mua o nā flocs i hana mua ʻia e CPAM.No laila, hoʻomaikaʻi ʻia ka nui o ka mālama ʻana i nā mea pepa, a ʻoi aku ka maikaʻi o ka hana like a me ka hoʻoheheʻe ʻana o ka pepa.

Ke hoʻohana ʻia ka AMPAM ma ke ʻano he kōkua paʻa a me ka hoʻoheheʻe wai, hoʻokuʻu nā pūʻulu anionic i ka ʻōpala anionic i loko o ka pulp, a hui pū nā hui cationic me nā fibers a me nā fibers maikaʻi.No laila, ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana i nā fibers maikaʻi.
