Yintoni eyenza iPolyacrylamide ibe luncedo kangaka kwiFlocculation?

I-PolyacrylamideIyaziwa ngokubanzi ngokusebenza kwayo kakuhle ekutsaleni inkunkuma, inkqubo ebalulekileyo kumashishini ahlukeneyo afana nonyango lwamanzi amdaka, ukumbiwa kwemigodi, kunye nokwenza iphepha. Le polymer yokwenziwa, eyenziwe ngee-acrylamide monomers, ineempawu ezikhethekileyo ezenza ukuba ifaneleke kakhulu kwizicelo ze-flocculation.

Okokuqala nokubalulekileyo, ubunzima obukhulu beemolekyuli zepolyacrylamide yinto ephambili enegalelo kubuchule bayo obubalaseleyo bokushukuma. Iintambo ezinde zeeyunithi ze-acrylamide eziphindaphindayo zivumela ukusebenzisana okukhulu neesuntswana ezixhonyiweyo kwisisombululo. Olu lwakhiwo lweemolekyuli luphucula amandla epolymer okwenza ii-flocs ezinkulu nezizinzileyo, ezizii-aggregates zeesuntswana ezincinci. Ngenxa yoko, ipolyacrylamide inokubopha kunye ngokufanelekileyo iisuntswana ezincinci, iququzelele ukuhla kwazo ngokukhawuleza okanye ukwahlukana kwazo nesigaba solwelo.

Indlela i-polyacrylamide enyibilikayo emanzini ngayo iphucula ngakumbi ukusebenza kwayo kwe-flocculation. Njengoko inyibilika emanzini, i-polyacrylamide inokusasazeka ngokulula kwaye ixutywe kwisisombululo, ukuqinisekisa ukusasazwa okufanayo kuyo yonke inkqubo. Olu phawu lubalulekile ekufezekiseni i-flocculation ehambelanayo nesebenzayo, njengoko i-polymer kufuneka idibane nazo zonke iinxalenye ezikwisisombululo ukuze zenze ii-floc.

Ukungathathi cala kwe-Polyacrylamide yenye into ebalulekileyo enegalelo ekusebenzeni kwayo kakuhle kwe-flocculation. I-polymer ngokubanzi ayisiyo-ionic, oko kuthetha ukuba ayinayo i-net electrical charge. Oku kungathath' icala kuvumela i-polyacrylamide ukuba isebenzisane noluhlu olubanzi lwee-particles, nokuba zingakanani na ii-surface charge zazo. Ngokwahlukileyo koko, ii-anionic okanye ii-cationic polymers zinokukhetha kwiipropati zazo ze-flocculation, nto leyo ethintela ukusetyenziswa kwazo kwiintlobo ezithile zee-particles. Ukungathath' icala kwe-Polyacrylamide kwenza ukuba isebenziseke kwaye ifaneleke kwiimeko ezahlukeneyo zonyango lwamanzi.

Ngaphezu koko, i-hydrolysis elawulwayo ye-polyacrylamide inokungenisa amaqela e-anionic, nto leyo ephucula ngakumbi ukusebenza kwayo kwe-flocculation. Ngokutshintsha iimpawu ze-polymer charge, isebenza ngakumbi ekutsaleni nasekunciphiseni amasuntswana anee-charges ezichaseneyo. Oku kuguquguquka kwindlela yokulawula i-charge kuvumela i-polyacrylamide ukuba ivumelane neendlela ezahlukeneyo zamanzi kwaye ilungelelanise amandla ayo e-flocculation ngokufanelekileyo.

Ukuguquguquka kwe-polyacrylamide ngokwemo yayo ebonakalayo kukwanegalelo ekusebenzeni kwayo kwiinkqubo ze-flocculation. Ifumaneka kwiintlobo ezahlukeneyo ezifana nee-emulsions, ii-powders, kunye nee-gels. Olu luhlu lweentlobo luvumela abasebenzisi ukuba bakhethe uhlobo olufanelekileyo ngokusekelwe kwiimfuno ezithile zezicelo zabo. Umzekelo, ii-emulsions zihlala zikhethwa ukuze kube lula ukuziphatha, ngelixa ii-powders zibonelela ngokulula ekugcinweni nasekuthuthweni.

Ukuqukumbela, ukusebenza kakuhle kwe-polyacrylamide kwi-flocculation kubangelwa bubunzima bayo obuphezulu beemolekyuli, ukunyibilika kwamanzi, ukungathathi cala kwe-charge, ukuguquguquka kokulawula i-charge, kunye nokuguquguquka kwimo yomzimba. Ezi mpawu xa zizonke zenza i-polyacrylamide ibe yi-polymer esebenza kakhulu kwaye eguquguqukayo ekuncedeni ukwakheka kwe-flocs ezizinzileyo, ngaloo ndlela inceda ekwahlukaniseni nasekususeni amasuntswana axhonyiweyo kwizisombululo zolwelo kwiinkqubo ezahlukeneyo zoshishino.
