Polyacrylamidendi madzi sungunuka liniya polima wopangidwa ndi ufulu kwakukulu mapolima polymerization wa acrylamide monomers.Pa nthawi yomweyo, hydrolyzed polyacrylamide ndi polima madzi mankhwala flocculant, amene akhoza kuyamwa.
tinthu tating'onoting'ono m'madzi, timagwirizanitsa ndi kulumikiza tinthu ting'onoting'ono, timapanga tinthu tating'ono ting'onoting'ono timene timatulutsa timadzi tambirimbiri, komanso timathamanga kwambiri mvula.
Polymer PHPkawirikawiri zikuphatikizapo mitundu itatu ya anionic, cationic ndi sanali ionic, ndipo pamaziko awa, pam Polyacrylamide wagawidwa mu zitsanzo zosiyanasiyana mndandanda.Poyang'anizana ndi mitundu yambiri ya polyacrylamide, omwe si akatswiri amatha kusamvetsetsana motere:
Kusamvetsetsa 1: Kukwera kwa molekyulu yolemetsa / ionicity, ndibwinoAnionic polyacrylamide nthawi zambiri imakhala ndi mitundu yosiyanasiyana kuyambira 3 miliyoni mpaka 22 miliyoni malinga ndi kulemera kwa maselo, pomwecationic polyacrylamideali ndi mitundu yosiyanasiyana kuyambira 30% mpaka 70%.
M'malo mwake, kusankha kwa polyacrylamide flocculant yokhala ndi kulemera kosiyanasiyana kwa maselo / ionicity kumakhala ndi kusiyana kwakukulu pamankhwala amtundu wamadzi osiyanasiyana.Kuchuluka kwa mlingo wa zotsatira zabwino ndizochepa kwambiri, ndipo ngati cationic pam idutsa muyeso wina, imayambitsa mavuto.Choncho, cationic polima msds m`pofunika kudziwa yoyenera yeniyeni chitsanzo cha Polyacrylamide malinga leni ntchito makampani, khalidwe madzi, zipangizo mankhwala ndi zinthu zina.
Kusamvetsetsa 2: Gwiritsani ntchito mtundu womwewo waPAMkwa mtundu womwewo wa madzi oipa
Mwachitsanzo, yemweyo papermaking madzi zinyalala angakhalenso kusiyana pH, organic kanthu, inorganic kanthu, chromaticity, SS, etc. Palibe mtundu umodzi wa polyacrylamide akhoza kuthetsa mavuto onse, ndi mitundu yonse ya zimbudzi kungakhale Njira kutsatira.Polyacrylamide mu ufa m'pofunika kusankha chitsanzo mwa mayeso ang'onoang'ono, ndiyeno kuyesa pa makina kudziwa mlingo mulingo woyenera kwambiri, kuti tikwaniritse zotsatira zabwino zochepa mlingo ndi mtengo wotsika.
Kusamvetsetsa 3: Kuchuluka kwa mlingo, kumakhala bwino
Nthawi zonse, mphamvu ya flocculation idzawonjezeka ndi kuwonjezeka kwa kuchuluka kwa flocculant, koma ngati kuchuluka kwa flocculant kuli kwakukulu, flocculant idzakhala colloid yokhazikika, ndi kukhuthala kwa madzi kudzawonjezeka, kotero kuti kukana kwa sedimentation. colloid yoyimitsidwa m'madzi idzawonjezeka.The akadakwanitsira mlingo analandira kudzera enieni zatsopano malinga ndi zili inaimitsidwa zolimba.
Nthano 4: Kuthamanga kwachangu kapena nthawi yayitali, kumakhala bwino
Ngati kuthamanga kwachangu kuli kofulumira komanso nthawi yayitali kwambiri, tinthu tating'onoting'ono tolimba timasweka
mu tinthu tating'onoting'ono, ndipo tinthu tating'onoting'ono tomwe titha kukhalapo titha kusweka kukhala tinthu tating'onoting'ono tomwe sitingathe kugwa.
Kusamvetsetsa 5: Kuthamanga kwachangu kumachedwa kwambiri kapena nthawi ndi yochepa kwambiri
Ngati liwiro ndi wodekha kwambiri ndi nthawi yochepa kwambiri, ndi flocculant sangathe bwinobwino kukhudzana olimba particles, amene si abwino kwa flocculant kugwila particles colloidal, ndi kugawa ndende ya flocculant si yunifolomu, amene kwambiri. osakhala bwino kusewera gawo la flocculant.
Kusamvetsetsa 6: cations,anions, ndipo osakhala ma ion sakudziwika bwino
Kusankha magulu ofunikira sikumveka bwino.Kusiyana kwamtengo pakati pa cation, anion ndi non-ion ndi yaikulu pang'ono, ndipo palibe njira yoyambira kuchokera kumbali zonse kapena kusankha gulu lolakwika.M'magwiritsidwe ntchito, amathanso kugawidwa motere:
Cationic Polyacrylamide ndi oyenera flocculation, sedimentation, decolorization, kumveka, etc. zovuta madzi khalidwe, m'tauni sludge dewatering, organic sludge dewatering, etc.; China Sewage Treatment Plant
Anions ndi abwino kwa zimbudzi flocculation, sedimentation, dewatering, kumveketsa, etc., ndipo angagwiritsidwenso ntchito madzi m'thupi la matope sludge;
Nonionic polyacrylamidendi oyenera nthaka posungira madzi, ofooka asidi zimbudzi flocculation, sedimentation, kuchepa madzi m'thupi, etc.
Malingaliro a kampani Yixing Cleanwater Chemicals Co., Ltd.ltd takhalanso okhazikika pakuwongolera zinthu ndi dongosolo la QC kuwonetsetsa kuti titha kusunga phindu lalikulu mkati mwa kampani yomwe ili ndi mpikisano wowopsa wa Massive Selection ku China Anionic PAM/Polyacrylamide ya Mapulogalamu Opangira Madzi, Ndi mfundo za "chikhulupiriro, kasitomala choyamba", yixing Cleanwater Chemicals Co., Ltd.olandirira ogula kuti azingotiimbira foni kapena kutumiza imelo kuti tigwirizane.
Kusankha Kwakukulu kwa opanga China sungunuka.
Kuchokera ku baidu.
