Polyacrylamidehe polymer linear wai-soluble i hoʻokumu ʻia e ka polymerization radical manuahi o nā monomers acrylamide. I ka manawa like, ʻo ka polyacrylamide hydrolyzed he flocculant mālama wai polymer hoʻi, hiki ke omo
nā ʻāpana i hoʻokuʻu ʻia i loko o ka wai, e pāʻani i kahi hana i ka hoʻopili ʻana a me ke alahaka ma waena o nā ʻāpana, e hana i nā ʻāpana liʻiliʻi e hana i nā flocs nui, a hoʻolalelale i ka wikiwiki o ka ua.
PHPA PolymerʻO ka maʻamau he ʻekolu ʻano o ka anionic, cationic a me ka non-ionic, a ma kēia kumu, ua māhele ʻia ka pam polyacrylamide i nā hiʻohiʻona moʻo like ʻole.I ke alo o nā ʻano polyacrylamide he nui, hiki i nā poʻe ʻoihana ʻole ke hāʻule i loko o nā kuhihewa ʻana penei:
Kuhihewa 1: ʻO ke kiʻekiʻe o ke kaumaha molekala/ionicity, ʻoi aku ka maikaʻiLoaʻa i ka polyacrylamide anionic nā ʻano hoʻohālike like ʻole mai 3 miliona a 22 miliona e like me ke kaumaha molekala, ʻoiaipolyacrylamide cationiche nui nā ʻano hoʻohālike like ʻole mai 30% a 70%.
ʻO kaʻoiaʻiʻo, ʻo ke koho ʻana o ka flocculant polyacrylamide me nā kaumaha molekala like ʻole/ionicity he ʻokoʻa nui ia i ka hopena mālama ʻana o nā ʻano wai like ʻole. He liʻiliʻi loa ka laulā dosage no ka hopena maikaʻi loa, a inā ʻoi aku ka nui o ka pam cationic ma mua o kahi laulā, e hana ia i nā hopena maikaʻi ʻole. No laila, pono nā msds polymer cationic e hoʻoholo i ke kumu hoʻohālike kūpono o ka polyacrylamide e like me ka ʻoihana noi maoli, ka maikaʻi o ka wai, nā lako mālama a me nā kūlana ʻē aʻe.
Kuhihewa 2: E hoʻohana i ke ʻano like oPAMno ke ʻano wai hoʻokahe like
No ka laʻana, ʻo ka wai hoʻokahe pepa like paha he ʻokoʻa i ka pH, nā mea organik, nā mea inorganic, chromaticity, SS, a pēlā aku. ʻAʻole hiki i hoʻokahi ʻano polyacrylamide ke hoʻoponopono i nā pilikia āpau, a hiki i nā ʻano wai hoʻokahe āpau ke hoʻokō i ke kaʻina hana. Pono ka Polyacrylamide i loko o ka POWDER e koho i ke kumu hoʻohālike ma o kahi hoʻāʻo liʻiliʻi, a laila e hoʻāʻo ma ka mīkini e hoʻoholo i ka dosage kūpono, i mea e loaʻa ai ka hopena maikaʻi loa o ka dosage liʻiliʻi a me ke kumukūʻai haʻahaʻa.
Kuhihewa 3: ʻOi aku ka nui o ka lāʻau, ʻoi aku ka maikaʻi
Ma lalo o nā kūlana maʻamau, e hoʻonui ʻia ka hopena flocculation me ka hoʻonui ʻia ʻana o ka nui o ka flocculant, akā inā nui loa ka nui o ka flocculant, e lilo hou ka flocculant i colloid paʻa, a e hoʻonui ʻia ka viscosity o ka wai, i mea e hoʻonui ai ke kūpaʻa o ka sedimentation o ke colloid i hoʻokuʻu ʻia i loko o ka wai. Loaʻa ka dosage kūpono ma o nā hoʻokolohua kikoʻī e like me ka nui o nā mea paʻa i hoʻokuʻu ʻia.
Ka Moʻolelo Hoʻokalakupua 4: ʻO ka wikiwiki o ka hoʻoulu ʻana a i ʻole ka lōʻihi o ka manawa, ʻoi aku ka maikaʻi
Inā wikiwiki loa ka wikiwiki o ka hoʻoulu ʻana a lōʻihi ka manawa, e haki nā ʻāpana nui o nā mea paʻa.
i loko o nā ʻāpana liʻiliʻi, a ʻo nā ʻāpana hiki ke hoʻopuka ʻia e wāwahi ʻia i nā ʻāpana i hiki ʻole ke hoʻopuka ʻia.
Kuhihewa 5: Lohi loa ka wikiwiki o ka hoʻoulu ʻana a pōkole paha ka manawa
Inā lohi loa ka wikiwiki a pōkole loa ka manawa, ʻaʻole hiki i ka flocculant ke hoʻopili piha i nā ʻāpana paʻa, ʻaʻole kūpono i ka flocculant e hopu i nā ʻāpana colloidal, a ʻaʻole like ka hoʻolaha ʻana o ka flocculant, ʻoi aku ka maikaʻi ʻole o ka pāʻani ʻana i ke kuleana o ka flocculant.
Kuhihewa 6: nā cations,nā anion, a he maopopo ʻole loa nā non-ion
ʻAʻole maopopo ke koho ʻana o nā māhele kumu. He nui iki ka ʻokoʻa kumukūʻai ma waena o ka cation, anion a me ka non-ion, a ʻaʻohe ala e hoʻomaka ai mai ke kuhikuhi maʻamau a koho paha i ka māhele hewa. I nā noi hana, hiki ke hoʻokaʻawale ʻia penei:
He kūpono ka polyacrylamide cationic no ka flocculation, sedimentation, decolorization, clarification, etc. o ka maikaʻi o ka wai paʻakikī, ka dewatering sludge kūlanakauhale, ka dewatering sludge organik, etc.; China Sewage Treatment Plant
He kūpono nā anions no ka flocculation o ka wai ʻino, ka sedimentation, ka dewatering, ka clarification, a pēlā aku, a hiki ke hoʻohana ʻia no ka dehydration o ka sludge inorganic;
ʻO ka polyacrylamide nonioniche kūpono no ka paʻa ʻana o ka wai o ka lepo, ka flocculation o ka wai ʻawaʻawa nāwaliwali, ka sedimentation, ka dehydration, a pēlā aku.
Ua loea pū ʻo Yixing cleanwater chemicals co. ltd i ka hoʻomaikaʻi ʻana i ka hoʻokele mea a me ka ʻōnaehana QC e hōʻoia i hiki iā mākou ke mālama i ka loaʻa nui i loko o ka hui hoʻokūkū ikaika no ka Massive Selection no Kina Anionic PAM / Polyacrylamide no nā noi mālama wai, Me ke kumumanaʻo o "manaʻoʻiʻo, mea kūʻai mua", yixing cleanwater chemicals co., ltd. hoʻokipa i nā mea kūʻai aku e kelepona mai a leka uila paha iā mākou no ke alu like.
Koho Nui no nā mea hana hoʻoheheʻe Kina.
