I-Polyacrylamideyipolymer ethe tyaba enyibilikayo emanzini eyenziwe yipolymerization ye-acrylamide monomers ekhululekileyo. Kwangaxeshanye, i-hydrolyzed polyacrylamide ikwayi-polymer yonyango lwamanzi, enokufunxa
amasuntswana axhonyiweyo emanzini, adlala indima ekudibaniseni nasekudibaniseni amasuntswana, enza amasuntswana amancinci enze iiflocs ezinkulu, kwaye akhawulezise isantya semvula.
I-PHPA yePolymeridla ngokuquka iintlobo ezintathu ze-anionic, i-cationic kunye ne-non-ionic, kwaye ngenxa yesi sizathu, i-pam polyacrylamide yahlulwe yaba ziimodeli ezahlukeneyo zochungechunge.Xa kukho iintlobo ezininzi ze-polyacrylamide, abantu abangengoochwephesha banokuwela kwezi ngxaki zilandelayo:
Ukungaqondi kakuhle 1: Okukhona ubunzima be-molecular/ionicity buphezulu, kokukhona ngconoI-Anionic polyacrylamide ngokubanzi ineentlobo ngeentlobo zeemodeli eziqala kwizigidi ezi-3 ukuya kwizigidi ezingama-22 ngokobunzima beemolekyuli, ngelixai-cationic polyacrylamideineentlobo ngeentlobo zeemodeli eziqala kwi-30% ukuya kwi-70%.
Enyanisweni, ukukhethwa kwe-polyacrylamide flocculant enobunzima/ionicity eyahlukileyo yemolekyuli kunomahluko omkhulu kwisiphumo sonyango somgangatho wamanzi owahlukileyo. Uluhlu lwedosi yesiphumo esingcono luncinci kakhulu, kwaye ukuba i-cationic pam idlula uluhlu oluthile, iya kubangela iziphumo ezibi. Ke ngoko, i-cationic polymer msds iyimfuneko ukumisela imodeli ethile efanelekileyo ye-polyacrylamide ngokweshishini lokwenyani lokusetyenziswa, umgangatho wamanzi, izixhobo zonyango kunye nezinye iimeko.
Ukungaqondi kakuhle 2: Sebenzisa uhlobo olufanayoI-PAMngohlobo olufanayo lwamanzi amdaka
Umzekelo, amanzi amdaka afanayo okwenza iphepha anokuba nomahluko kwi-pH, izinto eziphilayo, izinto ezingaphiliyo, i-chromaticity, i-SS, njl. Akukho luhlobo lunye lwe-polyacrylamide olunokusombulula zonke iingxaki, kwaye zonke iintlobo zenkunkuma zingahambelana neNkqubo. I-Polyacrylamide kwi-POWDER iyimfuneko ukukhetha imodeli ngovavanyo oluncinci, uze uyivavanye kumatshini ukuze ufumane idosi efanelekileyo, ukuze kufezekiswe isiphumo esingcono sedosi encinci kunye nexabiso eliphantsi.
Ukungaqondi kakuhle 3: Okukhona idosi ininzi, kokukhona ingcono
Phantsi kweemeko eziqhelekileyo, isiphumo sokuqunjelwa siya kwanda ngokwanda kobungakanani be-flocculant, kodwa ukuba ubungakanani be-flocculant buninzi kakhulu, i-flocculant iya kuba yi-colloid ezinzileyo kwakhona, kwaye i-viscosity yamanzi iya kwanda, ukuze ukumelana nokugalelwa kwe-colloid exhonyiweyo emanzini kwande. Umlinganiselo ofanelekileyo ufunyanwa ngovavanyo oluthile ngokomxholo wezinto eziqinileyo ezixhonyiweyo.
Intsomi 4: Okukhona isantya sokushukumisa sikhawuleza okanye ixesha lide, kokukhona kungcono
Ukuba isantya sokuxukuxa sikhawuleza kakhulu kwaye ixesha lide kakhulu, amasuntswana amakhulu ezinto eziqinileyo aya kuqhekeka
zibe ziisuntswana ezincinci, kwaye iisuntswana ezinokuqhekeka ziya kwaphulwa zibe ziisuntswana ezingenakuqhekeka.
Ukungaqondi kakuhle 5: Isantya sokushukumisa sicotha kakhulu okanye ixesha lifutshane kakhulu
Ukuba isantya sicotha kakhulu kwaye ixesha lifutshane kakhulu, i-flocculant ayinakukwazi ukuqhagamshelana ngokupheleleyo namaqhekeza aqinileyo, nto leyo engayivumeliyo i-flocculant ukubamba amaqhekeza e-colloidal, kwaye ukusasazwa koxinzelelo lwe-flocculant akuhambisani, nto leyo engathandekiyo nangakumbi ukudlala indima ye-flocculant.
Ukungaqondi kakuhle 6: ii-cations,ii-anions, kwaye ii-non-ion azicacanga ngobuyatha
Ukukhetha iindidi ezisisiseko akucaci. Umahluko wamaxabiso phakathi kwe-cation, i-anion kunye ne-non-ion mkhulu kancinci, kwaye akukho ndlela yokuqala kwicala eliqhelekileyo okanye ukukhetha udidi olungalunganga. Kwizicelo ezisebenzayo, inokwahlulwa ngolu hlobo:
I-Cationic polyacrylamide ifanelekile kwi-flocculation, sedimentation, decolorization, clarification, njl.njl. yomgangatho wamanzi onzima, ukucocwa kwedaka lasezidolophini, ukucocwa kwedaka eliphilayo, njl.njl.; iTshayina Sewage Treatment Plant
Ii-anion zifanelekile ukucocwa kwamanzi amdaka, ukutsalwa kwenkunkuma, ukucocwa kwamanzi, ukucaciswa, njl.njl., kwaye zingasetyenziselwa ukucocwa kwamanzi kwinkunkuma engaphiliyo;
I-polyacrylamide engeyiyo i-ionicifanelekile ekugcinweni kwamanzi emhlabeni, ukuqunjelwa kwamanzi amdaka ane-asidi ebuthathaka, ukutsalwa kwenkunkuma, ukuphelelwa ngamanzi emzimbeni, njl.
I-Yixing Cleanwater Chemicals Co. Ltd ikwagxile ekuphuculeni ulawulo lwezinto kunye nenkqubo ye-QC ukuqinisekisa ukuba singakwazi ukugcina inzuzo enkulu kwinkampani ekhuphisana kakhulu ye-Massive Selection ye-China Anionic PAM/Polyacrylamide yezicelo zoNyango lwaManzi, ngomgaqo "wokholo, umthengi kuqala", i-yixing Cleanwater Chemicals Co., Ltd. yamkela abathengi ukuba basitsalele umnxeba okanye basithumelele i-imeyile ukuze basebenzisane.
