Yini eyenza i-Polyacrylamide ibe ngcono kangaka ku-Flocculation?

I-Polyacrylamideiyaziwa kabanzi ngokusebenza kwayo kahle ekufakweni kwe-flocculation, inqubo ebalulekile ezimbonini ezahlukahlukene njengokwelashwa kwamanzi amdaka, ukumbiwa kwemigodi, kanye nokwenza amaphepha. Le polymer yokwenziwa, eyakhiwe ngama-acrylamide monomers, inezici ezihlukile ezenza ifaneleke kakhulu ekusetshenzisweni kwe-flocculation.

Okokuqala nokubaluleke kakhulu, isisindo sama-molecule aphezulu e-polyacrylamide siyisici esibalulekile esifaka isandla emandleni ayo ahlukile okuhambahamba. Amaketanga amade amayunithi e-acrylamide aphindaphindayo avumela ukusebenzisana okubanzi nezinhlayiya ezilengisiwe esixazululweni. Lesi sakhiwo sama-molecule sithuthukisa ikhono le-polymer lokwakha ama-floc amakhulu nazinzile, angamaqoqo ezinhlayiya ezincane. Ngenxa yalokho, i-polyacrylamide ingabopha ndawonye izinhlayiya ezincane ngempumelelo, isize ukuhlangana kwazo ngokushesha noma ukuhlukana kwazo nesigaba soketshezi.

Indlela i-polyacrylamide encibilika ngayo emanzini ithuthukisa ukusebenza kwayo kwe-flocculation. Njengoba incibilika emanzini, i-polyacrylamide ingahlakazeka kalula futhi ixutshwe ibe yisisombululo, iqinisekise ukusatshalaliswa okufanayo kulo lonke uhlelo. Lesi sici sibalulekile ekufezeni i-flocculation eqhubekayo nephumelelayo, njengoba i-polymer idinga ukuthintana nazo zonke izinhlayiya ezikusisombululo ukuze yakhe ama-floc.

Ukungathathi hlangothi kwe-Polyacrylamide kuyisici esibalulekile esifaka isandla ekusebenzeni kwayo kahle kwe-flocculation. I-polymer ngokuvamile ayiyona i-ionic, okusho ukuthi ayinayo i-net kagesi charge. Lokhu kungakhethi kuvumela i-polyacrylamide ukuthi isebenzisane nezinhlobo eziningi zezinhlayiya, kungakhathalekile ukuthi zingakanani i-surface charge. Ngokuphambene nalokho, ama-polymer e-anionic noma e-cationic angase akhethe izakhiwo zawo ze-flocculation, okunciphisa ukusebenza kwawo ezinhlotsheni ezithile zezinhlayiya. Ukungakhethi hlangothi kwe-Polyacrylamide kwenza kube lula futhi kufanelekele izimo ezahlukahlukene zokwelashwa kwamanzi.

Ngaphezu kwalokho, i-hydrolysis elawulwayo ye-polyacrylamide ingangenisa amaqembu e-anionic, ithuthukise ukusebenza kwayo kwe-flocculation. Ngokushintsha izici zokushaja ze-polymer, iba ngcono kakhulu ekudonseni nasekunciphiseni izinhlayiya ezinama-charge aphambene. Lokhu kuguquguquka kokuphathwa kwe-charge kuvumela i-polyacrylamide ukuthi izivumelanise nokwakheka kwamanzi okuhlukene futhi ivumelanise amakhono ayo e-flocculation ngokufanele.

Ukuguquguquka kwe-polyacrylamide ngokwesimo sayo esibonakalayo nakho kunegalelo ekusebenzeni kwayo kahle ezinqubweni ze-flocculation. Itholakala ngezindlela ezahlukene njenge-emulsions, impushana, nama-gel. Lokhu kuhlukahluka kwenza abasebenzisi bakwazi ukukhetha ifomu elifanele kakhulu ngokusekelwe ezidingweni ezithile zezicelo zabo. Isibonelo, ama-emulsions avame ukuthandwa ukuze kube lula ukuwaphatha, kuyilapho impushana inikeza lula ukugcina nokuthuthwa.

Ekuphetheni, ukusebenza kahle kwe-polyacrylamide kokuntanta okumangalisayo kubangelwa isisindo sayo esikhulu sama-molecule, ukuncibilika kwamanzi, ukungathathi hlangothi kwe-charge, ukuguquguquka kokuphathwa kwe-charge, kanye nokuguquguquka kwesimo somzimba. Lezi zakhiwo zenza i-polyacrylamide ibe yi-polymer esebenza kahle kakhulu futhi eguquguqukayo ekwenzeni lula ukwakheka kwe-flocs ezizinzile, ngaleyo ndlela isize ekuhlukaniseni nasekususeni izinhlayiya ezilengisiwe ezixazululweni zoketshezi ezinqubweni ezahlukahlukene zezimboni.
