Polyacrylamide (PAM) /nonionic polyacrylamide/cation polyacrylamide/anionic polyacrylamide, alias flocculant No. 3, he polymer linear hiki ke hoʻoheheʻe ʻia i ka wai i hana ʻia e ka polymerization radical manuahi o ka monomer acrylamide (AM).ʻO ka coagulation a me ka flocculation kaʻina i ka mālama wai, Polyacrylamide sds he 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.
ʻO ka polyacrylamide kahi ʻāpana pauka keʻokeʻo, hiki ke hoʻoheheʻe ʻia i loko o ka wai i kēlā me kēia ʻāpana, ʻokoʻa a ʻike ʻia ka wai aqueous, a piʻi nui ka viscosity o ka hoʻonā wai me ka piʻi ʻana 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 formaldehyde, ethanol, acetone, ether, etc.
ʻO Polyacrylamide kahi polymer hiki ke hoʻoheheʻe wai a i ʻole polyelectrolyte, nā mea hoʻomaʻemaʻe wai.Aia kekahi helu o nā pūʻulu polar i loko o ke kaulahao mole PAM, hiki ke hoʻopili i nā ʻāpana paʻa i hoʻokuʻu ʻia i loko o ka wai, e hana i nā alahaka ma waena o nā ʻāpana a i ʻole ma o ka hoʻokaʻawale ʻana, i hiki ai i nā ʻāpana ke agglomerate e hana i nā flocs nui.No laila, hiki i ka polyacrylamide ke hoʻolalelale i nā paʻa paʻa.ʻO ka hoʻoheheʻe ʻia ʻana o nā ʻāpana liʻiliʻi he hopena maopopo loa o ka wikiwiki ʻana i ka wehewehe ʻana o ka hopena a me ka hoʻoikaika ʻana i ka kānana.
Loaʻa i ka polyacrylamide ka monomer acrylamide ʻona.I loko o ka mālama wai inu i ʻōlelo ʻia ma koʻu ʻāina, ʻo ka nui i ʻae ʻia ʻo 0.01mg/L.I mea e pale aku ai i ka hoʻohaʻahaʻa ʻana o ka polyacrylamide, pono e mālama ʻia ka mahana mālama o kāna ʻano wai ʻaʻole i kiʻekiʻe ma mua o 40 ° C.I mea e pale aku ai i ka ʻike ʻana i ka lā, hiki ke hoʻohui ʻia kahi mea hoʻopaʻa liʻiliʻi, e like me ka sodium thiocyanate, sodium nitrite, etc., i ka hopena.Pono e hoʻopili ʻia ka pauka paʻa polyacrylamide i loko o nā pahu hao i uhi ʻia me nā ʻeke polyethylene i hoʻopaʻa ʻia a i ʻole i hoʻopaʻa ʻia me nā papa polyethylene, a hoʻopaʻa ʻia i mea e pale ai i ka ʻike ʻana i ka haʻahaʻa 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 ma lalo o 0 ° C.
Hiki ke hoʻohana nui ʻia ʻo China Dadmac, Poly Dadmac, PDADMAC i ka wai ʻona ʻenehana a me ka hoʻomaʻemaʻe wai ʻili a me ka hoʻomaʻemaʻe ʻana a me ka hoʻoheheʻe ʻana.Hiki iā ia ke hoʻomaikaʻi i ka mālamalama o ka wai ma kahi haʻahaʻa 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, pepa hana wai ʻino, kahua aila a me ka hoʻomaʻemaʻe aila wai ʻaila a me ka mālama ʻana i ke kaona.
ʻIkepili pāʻoihana: E lawe i ka mea kūʻai aku e like me ka Center, e lawe i ka maikaʻi e like me ke ola, ka pono, ke kuleana, ka nānā ʻana, ka hana hou. hui a neʻe pū i mua.
ʻO kā mākou pahuhopu nui, ʻo ia ka hāʻawi ʻana i kā mākou mea kūʻai aku i kahi pilina ʻoihana liʻiliʻi koʻikoʻi a kuleana, e hāʻawi ana i ka nānā pilikino iā lākou āpau no Professional China China Strong Cationic Group Radical Pdadmac Flocculant Agent, Hoʻokipa maikaʻi mākou i nā manaʻo, nā hui hui a me nā hoa mai nā wahi āpau o ka honua. e hoʻokaʻaʻike mai iā mākou a noi aku i ka launa pū ʻana no nā pono like.
ʻOihana Kina Kina Polyacrylamide Poly Dadmac, Pdadmac 26062 79 3, I mea e hoʻokō ai i ka koi nui o nā mea kūʻai aku ma ka home a me ka moku, e hoʻomau mākou i ka lawe ʻana i ka ʻuhane o ka ʻoihana o "Quality, Creativity, Efficiency and Credit" a hoʻoikaika i luna. ke au o keia manawa a me ke ano alakai.Hoʻokipa maikaʻi mākou iā ʻoe e kipa i kā mākou hui a hana i ka launa pū ʻana.
