Polyacrylamidehe polymer linear wai-soluble i hana ʻia e ka polymerization radical manuahi o nā monomers acrylamide.I ka manawa like, ʻo ka polyacrylamide hydrolyzed he flocculant mālama wai polymer, hiki ke komo.
nā ʻāpana i hoʻokuʻu ʻia i loko o ka wai, e pāʻani i ka hoʻopili ʻana a me ka hoʻopili ʻana ma waena o nā ʻāpana, e hana i nā ʻāpana maikaʻi e hana i nā flocs nui, a e hoʻolalelale i ka wikiwiki o ka ua.
Polimer PHPAmaʻa mau ʻekolu ʻano o ka anionic, cationic a me ka non-ionic, a ma kēia kumu, hoʻokaʻawale ʻia ka pam polyacrylamide i nā ʻano hoʻohālike like ʻole.I ke alo o nā ʻano polyacrylamide he nui, hiki i nā poʻe ʻoihana ʻole ke hāʻule i loko o nā kuhi hewa ʻole:
Misunderstanding 1: ʻO ke kiʻekiʻe o ke kaumaha molekala/ionicity, ʻoi aku ka maikaʻiʻO ka Anionic polyacrylamide maʻamau he mau hiʻohiʻona like ʻole mai 3 miliona a 22 miliona e like me ke kaumaha molekala, ʻoiaicationic polyacrylamideloaʻa nā ʻano hiʻohiʻona like ʻole mai 30% a 70%.
ʻO ka ʻoiaʻiʻo, ʻo ke koho ʻana o ka polyacrylamide flocculant me nā molecular kaumaha / ionicity he ʻokoʻa nui i ka hopena o ka mālama ʻana i nā ʻano wai like ʻole.He liʻiliʻi loa ka pae dosage no ka hopena maikaʻi loa, a inā ʻoi aku ka nui o ka cationic pam i kekahi ʻano, e hopena ia i nā hopena ʻino.No laila, pono ka cationic polymer msds e hoʻoholo i ke kumu hoʻohālike kūpono o ka polyacrylamide e like me ka ʻoihana noi maoli, ka maikaʻi o ka wai, nā mea lapaʻau a me nā kūlana ʻē aʻe.
Kuhihewa 2: E hoʻohana i ke ʻano like oPAMno ke ʻano wai ʻino
No ka laʻana, ka like papermaking wastewater hiki no hoi he like 'ole i loko o ka pH, organic mea, inorganic mea, chromaticity, SS, etc. 'A'ole kekahi 'ano o ka polyacrylamide hiki ke hoʻoponopono i nā pilikia a pau, a me nā 'ano o ka pauka hiki ke hoʻokō Kaʻina.Pono ka Polyacrylamide i POWDER e koho i ke kŘkohu ma o ka ho'āʻo liʻiliʻi, a laila e hoʻāʻo iā ia ma ka mīkini e hoʻoholo ai i ka dosage maikaʻi loa, i hiki ai ke hoʻokō i ka hopena maikaʻi loa o ka liʻiliʻi a me ka uku haʻahaʻa.
Misunderstanding 3: ʻO ka nui o ka dosage, ʻoi aku ka maikaʻi
Ma lalo o nā kūlana maʻamau, e hoʻonui ʻia ka hopena flocculation me ka piʻi ʻana o ka nui o ka flocculant, akā inā ʻoi aku ka nui o ka flocculant, e lilo hou ka flocculant i colloid paʻa, a piʻi ka viscosity o ka wai, no laila ke kūpaʻa ka sedimentation. e hoʻonui ʻia ka colloid i hoʻopaʻa ʻia i loko o ka wai.Loaʻa ka dosage maikaʻi loa ma o nā hoʻokolohua kikoʻī e like me ka ʻike o nā mea paʻa paʻa.
Myth 4: ʻO ka wikiwiki o ka hoʻoulu ʻana a i ʻole ka lōʻihi o ka manawa, ʻoi aku ka maikaʻi
Inā ʻoi aku 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 hoʻoheheʻe ʻia e wāwahi ʻia i mau ʻāpana hiki ʻole ke hoʻoheheʻe ʻia.
Misunderstanding 5: Ua lohi loa ka wikiwiki o ka hoʻoulu ʻana a i ʻole ka manawa pōkole
Inā lohi ka wikiwiki a pōkole 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 kūlike ka hāʻawi ʻana o ka flocculant, ʻoi aku ka nui. maikaʻi ʻole e pāʻani i ka hana o ka flocculant.
Hoʻomaopopo ʻole 6: cations,anions, a ʻaʻole maopopo nā non-ions
ʻAʻole maopopo ke koho ʻana i nā ʻano kumu.ʻO ka ʻokoʻa kumu kūʻai ma waena o ka cation, anion a me ka non-ion he mea nui, a ʻaʻohe ala e hoʻomaka ai mai ke kuhikuhi ākea a i ʻole koho i ka ʻāpana hewa.Ma nā noi kūpono, hiki ke hoʻokaʻawale ʻia e like me:
He kūpono ka cationic polyacrylamide no ka flocculation, sedimentation, decolorization, clarification, etc. o ka wai paʻakikī, sludge dewatering kūlanakauhale, organic sludge dewatering, etc.; China Sewage Treatment Plant
He kūpono nā Anion no ka hoʻoheheʻe ʻana i ka wai, sedimentation, dewatering, clarification, etc., a hiki ke hoʻohana ʻia no ka hoʻoheheʻe ʻana o ka ʻōpala inorganic;
Nonionic polyacrylamideHe kūpono ia no ka paʻa ʻana o ka wai lepo, ka waiʻawaʻawa palupalu flocculation, sedimentation, dehydration, etc.
ʻO Yixing Cleanwater Chemical Co.ʻO ltd kekahi mea kūikawā i ka hoʻomaikaʻi ʻana i nā mea hoʻokele a me ka ʻōnaehana QC e hōʻoia i hiki iā mākou ke mālama i ka waiwai nui i loko o ka ʻoihana hoʻokūkū ikaika no ka Massive Selection no Kina Anionic PAM/Polyacrylamide no nā noi wai wai, me ka ʻōlelo "hoʻokumu i ka hilinaʻi, mea kūʻai mua", yixing cleanwater chemicals co., ltd.hoʻokipa i nā mea kūʻai e kelepona a leka uila iā mākou no ka launa pū ʻana.
Koho nui no nā mea hana hoʻoheheʻe Kina Kina.
Wehe ʻia mai baidu.
