ʻO Polyacrylamide
ʻO Polyacrylamide kahi polymer linear, ua mahele nui ʻia ka huahana i ka pauka maloʻo a me colloidal ʻelua mau ʻano. Wahi a ka awelika kaulike kaulike, hiki ke hoʻokaʻawale ʻia i ke kaupaona molekole haʻahaʻa (<1 miliona), ke anawaena molakea waena (2 ~ 4 miliona) a me ke kaupaona molekole kiʻekiʻe (> .7 miliona). Wahi a kāna hanana hiki ke hoʻokaʻawale ʻia i non - ionic, anion a me cationic. Hoʻoneʻe wai (HPAM) o ke ʻano anion. Aia i ke kaulahao nui o polyacrylamide kahi nui o nā hui amide, me nā hana kemika kiʻekiʻe, a hiki ke hoʻololi ʻia e hana i nā mea nui o polyacrylamide. Ua hoʻohana ākea ʻia nā huahana i ka papermaking, hana ʻana i nā minelala, kāwili ʻia ʻana o ka aila, metallurgy, nā mea kūkulu hale, ka mālama ʻana i ka wai a me nā ʻoihana ʻē aʻe. Ma ke ʻano he lubricant, agena hoʻomaha, paʻa paʻa pālolo, aila hoʻoneʻe aila, mea hoʻohana e hoʻemi ana i ka wai a me nā mea mānoanoa, ua hoʻohana ākea ʻia ka polyacrylamide i ke kalai ʻana, ka hoʻohuihui ʻana, ka haki ʻana, ka hoʻopili ʻana i ka wai, ka hoʻowalewale ʻana, ka hoʻāla hou ʻana o ka aila ʻelua a me ka loaʻa hou o ka aila kiʻekiʻe

ʻO ka paʻi ʻana a me ka pena ʻana i ka wai me ka wai wainewater, ma kahi o nā coagulants mole mole haʻahaʻa, e pili ana i ka hana kuʻuna nui o ka coagulant, kiʻekiʻe ka maikaʻi o ka coagulation, optimum ph nā kūlana penei: 8.0.
