I-Polyacrylamide (PAM) Nokusetshenziswa Kwayo Ekuhlanzeni Amanzi

I-Polyacrylamide (PAM) kanye nokusetshenziswa kwayo ekwelashweni kwamanzi

Ukulawula ukungcoliswa kwamanzi kanye nokubusa kuyingxenye ebalulekile yokuvikelwa kwemvelo kanye nokulahlwa kokulungiswa kwamanzi angcolile thola ukunakwa okwengeziwe.

I-Polyacrylamide (PAM), i-polymer encibilikayo emanzini, iyindima ebaluleke kakhulu emkhakheni wokwelashwa kwamanzi ngenxa yesisindo samangqamuzana aphezulu, ukuncibilika kwamanzi, ukulawulwa kwesisindo samangqamuzana kanye nokuguqulwa okuhlukahlukene kokusebenza.

I-PAM kanye nokuphuma kwayo kungasetshenziswa njengama-flocculants asebenzayo, i-ejenti yokuqina, i-ejenti yokunciphisa ukudonsa, esetshenziswa kabanzi ekucubunguleni kwamanzi, ekwenzeni iphepha, i-petroleum, amalahle, i-geology, ukwakhiwa kanye neminye imikhakha yezimboni.

Emanzini angaphansi komhlaba, emanzini angaphezulu kanye nendle, ukungcola nokungcola kuvame ukuba khona njengezinhlayiya eziningi ezincane kakhulu ukuthi zingahlala ngaphansi kwamandla adonsela phansi.Ngenxa yokuthi i-sedimentation yemvelo ayikwazanga ukuhlangabezana nezidingo, ngosizo lwamakhemikhali ukusheshisa ukulungiswa kobuchwepheshe kusetshenziswe ekukhiqizeni.Isibonelo, i-molecule ye-PAM imunca izinhlayiya ezimbalwa futhi yenze i-floc enkulu, ngakho-ke, ukugcwala kwezinhlayiya kuyashesha.

Uma kuqhathaniswa ne-flocculant ye-inorganic, i-PAM inezinzuzo ezimbalwa ezibalulekile: izinhlobonhlobo eziningi zezimo ezihlukahlukene, ukusebenza kahle okuphezulu, umthamo omncane, udaka olukhiqizwayo oluncane, ukwelashwa okulula ngemva kokwelashwa.Lokhu kuyenza ibe i-flocculant ekahle kakhulu.

Kumayelana nomthamo we-inorganic coagulant 1/30 kuya ku-1/200.

I-PAM ithengiswa ngezindlela ezimbili eziyinhloko: i-powder ne-emulsion.

I-powder PAM kulula ukuyihambisa, kodwa akulula ukuyisebenzisa (amadivaysi okuchithwa ayadingeka), kuyilapho i-emulsion ingekho lula ukuthutha futhi inokuphila okufushane yokugcina.

I-PAM inokuncibilika okukhulu emanzini, kodwa incibilika kancane kakhulu.Ukuchithwa kubiza amahora ambalwa noma ubusuku bonke.Ukuxuba okuhle komshini kuzosiza ukuqeda i-PAM.Engeza kancane kancane i-PAM emanzini anyakazayo - hhayi amanzi ku-PAM.

Ukushisa kungakhuphula kancane izinga lokuncibilika, kodwa izinga lokushisa akufanele lidlule ku-60°C.

Ukugxiliswa okuphezulu kwe-PAM kwesisombululo se-polymer ngu-0.5%, ukugxila kwe-PAM yamangqamuzana aphansi kungahlelwa ku-1% noma ngaphezulu kancane.

Isixazululo se-PAM esilungisiwe kufanele sisetshenziswe ezinsukwini ezimbalwa, ngaphandle kwalokho ukusebenza kwe-flocculation kuzothinteka.
