ʻO Polyacrylamide (PAM) /nonionic polyacrylamide/cation polyacrylamide/anionic polyacrylamide, ʻo ia hoʻi ka flocculant No. 3, he polymer linear wai-soluble i hoʻokumu ʻia e ka polymerization radical manuahi o ka monomer acrylamide (AM). Ke kaʻina hana coagulation a me ka flocculation i ka mālama ʻana i ka wai, loaʻa i ka Polyacrylamide sds ka flocculation maikaʻi a hiki ke hōʻemi i ka friction ma waena o nā wai Hiki ke hoʻokaʻawale ʻia ke kū'ē i ʻehā mau ʻano: anionic, cationic, nonionic a me amphoteric e like me nā waiwai ionic.
He ʻāpana pauka keʻokeʻo ka Polyacrylamide, hiki ke hoʻoheheʻe ʻia i loko o ka wai ma kekahi ʻano, like a moakaka ka hopena wai, a piʻi nui ka mānoanoa o ka hopena wai me ka hoʻonui ʻia o ke kaumaha molekala pili o ka polymer. ʻAʻole hiki ke hoʻoheheʻe ʻia ka PAM i ka hapa nui o nā mea hoʻoheheʻe organik, e like me ka formaldehyde, ethanol, acetone, ether, a pēlā aku.
He polymer wai-soluble a polyelectrolyte paha ka Polyacrylamide, he mau kemika hoʻomaʻemaʻe wai. Aia kekahi mau hui polar i loko o ke kaulahao molekala PAM, hiki ke hoʻopili i nā ʻāpana paʻa i kau ʻia i loko o ka wai hoʻoheheʻe, hana i nā alahaka ma waena o nā ʻāpana a i ʻole ma o ka hoʻemi ʻana i ka uku, i hiki ai i nā ʻāpana ke hōʻuluʻulu e hana i nā flocs nui. No laila, hiki i ka polyacrylamide ke hoʻolalelale i nā mea paʻa i kau ʻia. ʻO ka sedimentation o nā ʻāpana waena he hopena maopopo loa ia o ka hoʻolalelale ʻana i ka wehewehe ʻana o ka hopena a me ka hoʻolaha ʻana i ka kānana.
Loaʻa i ka Polyacrylamide ka monomer acrylamide ʻawahia ʻole. I ka mālama ʻana i ka wai inu i hoʻopaʻa ʻia ma koʻu ʻāina, ʻo ka nui i ʻae ʻia he 0.01mg/L. I mea e pale ai i ka hōʻino ʻia o ka polyacrylamide, pono e hoʻomalu ʻia ka mahana mālama o kāna wai wai ʻaʻole e ʻoi aku ma mua o 40°C. I mea e pale ai i ka ʻike ʻana i ka lā, hiki ke hoʻohui ʻia kahi liʻiliʻi o ka mea hoʻopaʻa, e like me ka sodium thiocyanate, sodium nitrite, a pēlā aku, i ka wai. Pono e hoʻopaʻa ʻia ka pauka paʻa Polyacrylamide i loko o nā pahu hao i uhi ʻia me nā ʻeke polyethylene pale makū a i ʻole i uhi ʻia me nā papa polyethylene, a sila ʻia e pale ai i ka ʻike ʻana i ka makū kiʻekiʻe.
Pono e hoʻopili ʻia ka polyacrylamide wai a laila waiho ʻia i loko o nā pahu lāʻau a i ʻole nā pahu hao. ʻO ka manawa mālama ma kahi o 3 a 6 mau mahina. Pono e hoʻoulu ʻia ma mua o ka hoʻohana ʻana. ʻAʻole pono ke kiʻekiʻe o ka mahana mālama ma mua o 32°C a ʻoi aku ka haʻahaʻa ma mua o 0°C.
Hiki ke hoʻohana nui ʻia ʻo China Dadmac, Poly Dadmac, PDADMAC i ka wai ʻōpala ʻoihana a me ka hoʻomaʻemaʻe ʻana i ka wai ʻili a me ka hoʻomānoanoa ʻana i ka sludge a me ka dewatering. Hiki iā ia ke hoʻomaikaʻi i ka moakāka o ka wai ma kahi haʻahaʻa. Loaʻa iā ia ka hana maikaʻi e hoʻolalelale i ka nui o ka sedimentation. He kūpono ia no kahi ākea o ka pH 4-10.
Hiki ke hoʻohana ʻia kēia huahana i ka wai ʻōpala colliery, ka wai ʻōpala hana pepa, ke kahua aila a me ka hale hoʻomaʻemaʻe aila a me ka wai ʻōpala ʻaila a me ka mālama ʻana i ka wai ʻōpala kūlanakauhale.
ʻIke loea ʻoihana: E lawe i ka mea kūʻai aku ma ke kikowaena, e lawe i ka maikaʻi e like me ke ola, ka pono, ke kuleana, ka nānā ʻana, ka hana hou. E hāʻawi mākou i nā mea kūpono, ka maikaʻi ma ke ʻano he uku no ka hilinaʻi o nā mea kūʻai aku, me ka hapa nui o nā mea hoʻolako honua nui e hana pū kā mākou poʻe limahana a neʻe pū i mua.
ʻO kā mākou pahuhopu nui ka hāʻawi ʻana i kā mākou mea kūʻai aku i kahi pilina ʻoihana liʻiliʻi koʻikoʻi a kuleana hoʻi, e hāʻawi ana i ka nānā pilikino iā lākou āpau no ka ʻOihana Kina Kina Ikaika Cationic Group Radical Pdadmac Flocculant Agent, Hoʻokipa maikaʻi mākou i nā mea kūʻai aku, nā hui ʻoihana a me nā hoaaloha mai nā wahi a pau o ka honua e hoʻokaʻaʻike mai iā mākou a noi i ka laulima no nā pono like.
ʻO ka Polyacrylamide Poly Dadmac Kina ʻoihana, Pdadmac 26062 79 3, I mea e hoʻokō ai i nā koi e piʻi nei o nā mea kūʻai aku ma ka home a ma luna o ka moku, e hoʻomau mākou i ka hoʻomau ʻana i ka ʻuhane ʻoihana o "Quality, Creativity, Efficiency and Credit" a e hoʻoikaika e lanakila i ke ʻano o kēia manawa a alakaʻi i ke ʻano. Hoʻokipa maikaʻi mākou iā ʻoe e kipa i kā mākou hui a hana i ka laulima.
