I-Polyacrylamideiyi-polymer eqondile encibilikayo emanzini eyakhiwe yi-polymerization yama-acrylamide monomers yamahhala. Ngesikhathi esifanayo, i-hydrolyzed polyacrylamide nayo iyi-flocculant yokwelapha amanzi ye-polymer, engamunca
izinhlayiya ezilenga emanzini, zidlala indima ekuhlanganiseni nasekuhlanganiseni izinhlayiya, zenze izinhlayiya ezincane zakhe ama-floc amakhulu, futhi zisheshise isivinini semvula.
I-PHPA ye-Polymerngokuvamile ihlanganisa izinhlobo ezintathu ze-anionic, i-cationic kanye ne-non-ionic, futhi ngenxa yalokhu, i-pam polyacrylamide ihlukaniswe ngamamodeli ahlukene ochungechunge.Uma bebhekene nezinhlobo eziningi ze-polyacrylamide, abangebona ochwepheshe bangase bawele ekungaqondani okulandelayo:
Ukungaqondi kahle 1: Uma isisindo sama-molecule/ionicity siphakeme, kuba ngconoI-Anionic polyacrylamide ngokuvamile inamamodeli ahlukahlukene asukela ezigidini ezintathu kuya kwezingama-22 ngokwesisindo sama-molecule, kuyilaphoi-cationic polyacrylamideinezinhlobo ezahlukene zamamodeli asukela ku-30% kuya ku-70%.
Eqinisweni, ukukhethwa kwe-polyacrylamide flocculant enesisindo/ionicity yama-molecule ahlukene kunomehluko omkhulu emphumeleni wokwelashwa wekhwalithi yamanzi ehlukene. Ububanzi bomthamo womphumela omuhle kakhulu buncane kakhulu, futhi uma i-cationic pam idlula ububanzi obuthile, kuzodala imiphumela emibi. Ngakho-ke, ama-cationic polymer msds ayadingeka ukuze kunqunywe imodeli ethile efanele ye-polyacrylamide ngokuya ngemboni yokusetshenziswa yangempela, ikhwalithi yamanzi, imishini yokwelapha nezinye izimo.
Ukungaqondi kahle 2: Sebenzisa uhlobo olufanayo lweI-PAMngohlobo olufanayo lwamanzi angcolile
Isibonelo, amanzi angcolile afanayo okwenza iphepha angase abe nomehluko ku-pH, izinto eziphilayo, izinto ezingaphili, i-chromaticity, i-SS, njll. Akukho nolulodwa uhlobo lwe-polyacrylamide olungaxazulula zonke izinkinga, futhi zonke izinhlobo zendle zingahambisana nenqubo. I-Polyacrylamide ku-POWDER iyadingeka ukukhetha imodeli ngokuhlolwa okuncane, bese uyihlola emshinini ukuze kutholakale umthamo ofanele, ukuze kufezwe umphumela omuhle kakhulu womthamo omncane kanye nezindleko eziphansi.
Ukungaqondi kahle 3: Uma umthamo uphezulu, kuba ngcono
Ngaphansi kwezimo ezivamile, umphumela wokugoba uzokhula ngokwanda kwenani le-flocculant, kodwa uma inani le-flocculant liphezulu kakhulu, i-flocculant izoba yi-colloid ezinzile futhi, futhi i-viscosity yamanzi izokwanda, ukuze ukumelana nokuthungwa kwe-colloid emisiwe emanzini kukhule. Umthamo ofanele utholakala ngokuhlolwa okuthile ngokuya ngokuqukethwe kwezinto eziqinile ezimisiwe.
Inganekwane 4: Uma isivinini sokushukumisa sishesha noma isikhathi eside, kungcono
Uma ijubane lokuxubha lishesha kakhulu futhi isikhathi side kakhulu, izinhlayiya ezinkulu zezinto eziqinile zizophuka
zibe yizinhlayiya ezincane, kanti izinhlayiya ezingaba khona zizoqhekeka zibe yizinhlayiya ezingenakukwazi ukuba khona.
Ukungaqondi kahle 5: Ijubane lokuxuba lihamba kancane kakhulu noma isikhathi sifushane kakhulu
Uma ijubane lihamba kancane kakhulu futhi isikhathi sifushane kakhulu, i-flocculant ayikwazi ukuxhumana ngokugcwele nezinhlayiya eziqinile, okungavumeli i-flocculant ukuthi ibambe izinhlayiya ze-colloidal, futhi ukusatshalaliswa kokuhlushwa kwe-flocculant akufani, okuyinto engathandeki nakakhulu ukudlala indima ye-flocculant.
Ukungaqondi kahle 6: ama-cation,ama-anion, futhi okungewona ama-ion akucaci ngobuwula
Ukukhetha izigaba eziyisisekelo akucaci. Umehluko wentengo phakathi kwe-cation, i-anion kanye ne-non-ion mkhulu kancane, futhi ayikho indlela yokuqala kusukela ohlangothini olujwayelekile noma ukukhetha isigaba esingalungile. Ekusetshenzisweni okusebenzayo, kungahlukaniswa cishe kanje:
I-Cationic polyacrylamide ifanelekela ukugoqa, ukuthungwa, ukususwa kombala, ukucaciswa, njll. kwekhwalithi yamanzi eyinkimbinkimbi, ukususwa kodaka lwasedolobheni, ukususwa kodaka olungokwemvelo, njll.; Isitshalo Sokwelapha Indle SaseShayina
Ama-anion afanelekela ukugeleza kwendle, ukuthuthwa kwendle, ukususwa kwamanzi, ukucaciswa, njll., futhi angasetshenziswa nasekuphelelweni kwamanzi kodaka olungaphili;
I-polyacrylamide engeyona i-ionicifanele ukugcinwa kwamanzi enhlabathini, ukukhukhuleka kwendle okubuthakathaka kwe-asidi, ukuthuthwa kwenhlabathi, ukuphelelwa amanzi emzimbeni, njll.
I-Yixing cleanwater Chemicals Co. Ltd ibilokhu igxile ekuthuthukiseni ukuphathwa kwezinto kanye nohlelo lwe-QC ukuqinisekisa ukuthi singakwazi ukugcina inzuzo enkulu enkampanini encintisana kakhulu ye-Massive Selection for China Anionic PAM/Polyacrylamide for Water Treatment Applications, ngomgomo "wokholo, amakhasimende kuqala", i-yixing cleanwater Chemicals Co., Ltd. yamukela abathengi ukuthi basishayele ucingo noma basithumelele i-imeyili ukuze sibambisane.
Ukukhetha Okukhulu Kwabakhiqizi Abancibilikayo BaseShayina.
