Polyacrylamidendi polima yosungunuka m'madzi yopangidwa ndi polymerization ya acrylamide monomers yaulere. Nthawi yomweyo, polyacrylamide yokhala ndi hydrolyzed ndi flocculant yochizira madzi ya polima, yomwe imatha kuyamwa.
Tinthu tating'onoting'ono tomwe timapachikidwa m'madzi, timagwira ntchito yolumikiza ndi kulumikiza tinthu tating'onoting'ono, timapangitsa tinthu tating'onoting'ono kupanga ma flocs akuluakulu, ndikufulumizitsa liwiro la mvula.
PHPA ya polimaKawirikawiri imakhala ndi mitundu itatu ya anionic, cationic ndi non-ionic, ndipo pamaziko awa, pam polyacrylamide imagawidwa m'mitundu yosiyanasiyana.Poyang'anizana ndi mitundu yambiri ya polyacrylamide, anthu omwe si akatswiri angakumane ndi kusamvetsetsana kotsatiraku:
Kusamvetsetsana 1: Kulemera/ionicity ya mamolekyulu ikakwera, zimakhala bwinoAnionic polyacrylamide nthawi zambiri imakhala ndi mitundu yosiyanasiyana kuyambira 3 miliyoni mpaka 22 miliyoni malinga ndi kulemera kwa maselo, pomwepolyacrylamide ya cationicIli ndi mitundu yosiyanasiyana kuyambira 30% mpaka 70%.
Ndipotu, kusankha polyacrylamide flocculant yokhala ndi kulemera/ionicity yosiyana kwa mamolekyulu kuli ndi kusiyana kwakukulu pa zotsatira za chithandizo cha madzi osiyanasiyana. Mlingo wa zotsatira zabwino kwambiri ndi wochepa kwambiri, ndipo ngati cationic pam ipitirira mtunda winawake, ingayambitse zotsatira zoyipa. Chifukwa chake, cationic polymer msds ndizofunikira kuti mudziwe mtundu woyenera wa polyacrylamide malinga ndi makampani enieni ogwiritsira ntchito, mtundu wa madzi, zida zochizira ndi zina.
Kusamvetsetsana 2: Gwiritsani ntchito mtundu womwewo waPAMza mtundu womwewo wa madzi otayira
Mwachitsanzo, madzi otayira omwewo omwe amapanga mapepala angakhalenso ndi kusiyana kwa pH, zinthu zachilengedwe, zinthu zopanda chilengedwe, chromaticity, SS, ndi zina zotero. Palibe mtundu umodzi wa polyacrylamide womwe ungathetse mavuto onse, ndipo mitundu yonse ya zinyalala imatha kutsatira njira. Polyacrylamide mu UFUTA ndiyofunikira kuti musankhe chitsanzo kudzera mu mayeso ang'onoang'ono, kenako muyesere pamakina kuti mudziwe mlingo woyenera, kuti mupeze zotsatira zabwino kwambiri za mlingo wochepa komanso mtengo wotsika.
Kusamvetsetsana 3: Mlingo wochuluka, umakhala wabwino kwambiri
Muzochitika zachizolowezi, mphamvu ya flocculation imawonjezeka ndi kuchuluka kwa flocculant, koma ngati kuchuluka kwa flocculant kuli kochulukira, flocculant idzakhalanso colloid yokhazikika, ndipo kukhuthala kwa madzi kudzawonjezeka, kotero kuti kukana kwa sedimentation kwa colloid yopachikidwa m'madzi kudzawonjezeka. Mlingo woyenera umapezeka kudzera mu kuyesa kwina malinga ndi kuchuluka kwa zinthu zolimba zopachikidwa.
Bodza Lachinayi: Liwiro losuntha mofulumira kapena nthawi yayitali, zimakhala bwino
Ngati liwiro loyambitsa ndi lachangu kwambiri ndipo nthawi ndi yayitali kwambiri, tinthu tating'onoting'ono ta zinthu zolimba timasweka.
kukhala tinthu tating'onoting'ono, ndipo tinthu tomwe tingagwedezeke tidzasweka kukhala tinthu tomwe sitingathe kugwedezekeka.
Kusamvetsetsana 5: Liwiro loyambitsa ndi lochedwa kwambiri kapena nthawi ndi yochepa kwambiri
Ngati liwiro lake ndi lochedwa kwambiri ndipo nthawi yake ndi yochepa kwambiri, flocculant silingathe kukhudza tinthu tolimba, zomwe sizingathandize flocculant kugwira tinthu ta colloidal, ndipo kufalikira kwa flocculant sikofanana, zomwe zimakhala zosasangalatsa kwambiri kusewera gawo la flocculant.
Kusamvetsetsana 6: ma cations,anionsndipo zinthu zopanda ma ioni sizikudziwika bwino
Kusankha magulu oyambira sikudziwika bwino. Kusiyana kwa mitengo pakati pa cation, anion ndi non-ion ndi kwakukulu pang'ono, ndipo palibe njira yoyambira kuchokera mbali zonse kapena kusankha gulu lolakwika. Mu ntchito zenizeni, zitha kugawidwanso m'magulu ngati:
Cationic polyacrylamide ndi yoyenera kusakaniza madzi, kusungunula, kusintha mtundu, kuyeretsa, ndi zina zotero. za ubwino wa madzi ovuta, kuchotsa madzi m'matauni, kuchotsa madzi m'matope achilengedwe, ndi zina zotero; China Sewage Treatment Plant
Anions ndi oyenera kutayira madzi m'zimbudzi, kuyika m'matope, kuchotsa madzi m'madzi, kuyeretsa, ndi zina zotero, ndipo angagwiritsidwenso ntchito pochotsa madzi m'matope osapangidwa ndi zinthu zachilengedwe;
Polyacrylamide yosakhala ya ionicndi yoyenera kusunga madzi m'nthaka, kusungunuka kwa zinyalala za asidi wofooka, kusungunuka kwa nthaka, kusowa madzi m'nthaka, ndi zina zotero.
Kampani ya Yixing cleanwater Chemicals Co., Ltd yakhala ikugwira ntchito yokonza kayendetsedwe ka zinthu ndi QC kuti iwonetsetse kuti titha kusunga phindu lalikulu mu kampani yomwe ikupikisana kwambiri ndi Massive Selection ya China Anionic PAM/Polyacrylamide for Water Treatment Applications, ndi mfundo ya "makasitomala odzipereka, makasitomala oyamba", yixing cleanwater Chemicals Co., Ltd. ikulandirani ogula kuti azingoyimba foni kapena kutitumizira imelo kuti atithandize.
Kusankha Kwakukulu kwa opanga osungunuka aku China.
Yatengedwa kuchokera ku baidu.
