I-Polyacrylamideiyi-polymer ewumugqa encibilika emanzini eyakhiwe yi-polymerization yamahhala yama-acrylamide monomers. Ngasikhathi sinye, i-hydrolyzed polyacrylamide nayo iyi-flocculant yokwelapha amanzi e-polymer, engamunca.
izinhlayiya ezilengisiwe emanzini, zidlala indima ekuxhumaniseni nasekuhlanganiseni phakathi kwezinhlayiya, zenze izinhlayiya ezicolekile zakhe ama-flocs amakhulu ngokuqhathaniswa, futhi zisheshise isivinini semvula.
I-Polymer PHPngokuvamile kuhlanganisa izinhlobo ezintathu ze-anionic, i-cationic kanye ne-non-ionic, futhi ngalesi sisekelo, i-pam polyacrylamide ihlukaniswe ngamamodeli ahlukene ochungechunge.Lapho bebhekene nezinhlobo eziningi ze-polyacrylamide, abangebona ochwepheshe bangase bawele kulokhu kungaqondi kahle okulandelayo:
Ukungaqondi kahle 1: Ukuphakama kwesisindo se-molecular/ionicity, kuba ngconoI-Anionic polyacrylamide ngokuvamile inezinhlobonhlobo zamamodeli asukela ezigidini ezi-3 kuye kwezingama-22 ngokwesisindo samangqamuzana, kuyilaphoi-polyacrylamide ye-cationicinamamodeli ahlukahlukene asukela ku-30% kuya ku-70%.
Eqinisweni, ukukhethwa kwe-polyacrylamide flocculant enesisindo esihlukile samangqamuzana/ionicity kunomehluko omkhulu emthelela wokwelapha wekhwalithi yamanzi ehlukene. Ibanga lomthamo womphumela ongcono kakhulu lincane kakhulu, futhi uma i-cationic pam idlula ububanzi obuthile, izodala imiphumela emibi. Ngakho-ke, i-cationic polymer msds iyadingeka ukucacisa imodeli ethize efanele ye-polyacrylamide ngokusho kwemboni yesicelo sangempela, ikhwalithi yamanzi, imishini yokwelapha kanye nezinye izimo.
Ukungaqondi kahle 2: Sebenzisa uhlobo olufanayo lwePAMohlotsheni olufanayo lwamanzi angcolile
Isibonelo, amanzi angcolile afanayo okwenza iphepha angase abe nomehluko ku-pH, izinto eziphilayo, izinto ezingaphili, i-chromaticity, i-SS, njll. Alukho uhlobo olulodwa lwe-polyacrylamide olungaxazulula zonke izinkinga, futhi zonke izinhlobo zokukhucululwa kwendle zingaba Ukuthobela Inqubo. I-Polyacrylamide ku-POWDER iyadingeka ukuze ukhethe imodeli ngokuhlolwa okuncane, bese uyivivinya emshinini ukuze unqume umthamo olungile, ukuze kuzuzwe umphumela omuhle kakhulu womthamo omncane kanye nezindleko eziphansi.
Ukungaqondi kahle 3: Uma umthamo uyanda, uba ngcono
Ngaphansi kwezimo ezijwayelekile, umphumela we-flocculation uzokhula ngokwanda kwenani le-flocculant, kodwa uma inani le-flocculant lidlula ngokweqile, i-flocculant izoba i-colloid ezinzile futhi, futhi i-viscosity yamanzi izokwanda, ukuze ukumelana ne-sedimentation. ye-colloid emisiwe emanzini izokwanda. Umthamo omkhulu utholakala ngokuhlolwa okuthile ngokuya ngokuqukethwe okuqinile okumisiwe.
Inganekwane yesi-4: Ukushesha kwejubane elinyakazayo noma isikhathi eside, kuba ngcono
Uma ijubane elinyakazayo lishesha kakhulu futhi isikhathi siside kakhulu, izinhlayiya ezinkulu zezinto eziqinile zizophulwa
zibe izinhlayiya ezincane, futhi izinhlayiya ezingase zidonseke zizophulwa zibe yizinhlayiya ezingenakunqotshwa.
Ukungaqondi kahle 5: Ijubane lokunyakazisa lihamba kancane noma isikhathi sifushane kakhulu
Uma ijubane lihamba kancane futhi isikhathi sisifushane kakhulu, i-flocculant ayikwazi ukuxhumana ngokugcwele nezinhlayiya eziqinile, ezingahambisani ne-flocculant ukuze ibambe izinhlayiya ze-colloidal, futhi ukusatshalaliswa kokuhlushwa kwe-flocculant akufani, okungaphezulu nakakhulu. engalungile ukudlala indima ye-flocculant.
Ukungaqondi kahle 6: ama-cations,ama-anions, futhi okungewona ama-ion akucaci kahle
Ukukhethwa kwezigaba eziyisisekelo akucacile. Umehluko wamanani phakathi kwe-cation, anion kanye ne-non-ion mkhulu kancane, futhi ayikho indlela yokuqala kusukela ekuqondeni okujwayelekile noma ukukhetha isigaba esingalungile. Ekusetshenzisweni okungokoqobo, kungase futhi kuhlelwe ngokuthi:
I-Cationic polyacrylamide ifanele ukugeleza kwamanzi, ukubola, ukuchithwa kwemibala, ukucaciswa, njll. yekhwalithi yamanzi eyinkimbinkimbi, ukuchithwa kodaka lwasemadolobheni, ukuchithwa kwe-organic sludge, njll.
Ama-Anions afanele ukugeleza kwendle, ukucwiliswa kwendle, ukuchithwa kwamanzi, ukucaciswa, njll., futhi angasetshenziselwa ukuphelelwa amandla kwamanzi kwe-sludge ye-inorganic;
I-Nonionic polyacrylamideilungele ukugcinwa kwamanzi enhlabathini, i-acid ebuthakathaka i-sewage flocculation, i-sedimentation, ukuphelelwa amandla kwamanzi, njll.
Inkampani engu-Yixing Cleanwater Chemicals Co. I-ltd ibisebenza ngokukhethekile ekuthuthukiseni ukuphathwa kwezinto kanye nesistimu ye-QC ukuze siqinisekise ukuthi singalondoloza inzuzo enkulu ngaphakathi kwenkampani eqhudelana kakhulu ngokukhetha i-Massive Selection ye-China Anionic PAM/Polyacrylamide Yezicelo Zokuhlanza Amanzi, Ngomgomo "osekelwe okholweni, ikhasimende kuqala", yixing cleanwater chemicals co., Ltd. wamukelekile abathengi ukuthi bamane basishayele noma basithumele i-imeyili ukuze sibambisane.
Ukukhetha Okukhulu kwabakhiqizi baseChina abancibilikayo.
