I-Polyacrylamide(PAM), njenge-ejenti ebalulekile yokwelapha amanzi, isetshenziswa kabanzi emikhakheni eyahlukene yezimboni. Kodwa-ke, ukuncibilikisa i-PAM kungaba yinselele kubasebenzisi abaningi. Imikhiqizo ye-PAM esetshenziswa emanzini angcolile ezimbonini iza ngezindlela ezimbili: impuphu eyomile kanye ne-emulsion. Lesi sihloko sizokwethula indlela yokuncibilikisa yezinhlobo ezimbili ze-PAM ngokuningiliziwe ukuqinisekisa ukuthi abasebenzisi bathola imiphumela emihle kakhulu ekusebenzeni kwangempela.
Indlela yokuncibilikisa ngqo iyindlela elula nevame kakhulu yokuncibilikisa i-PAM. Le ndlela ifaneleka ku-PAM powder enesisindo esincane sama-molecule futhi kulula ukuyincibilikisa. Nazi izinyathelo ezithile:
Lungisa Isitsha: Khetha isitsha sepulasitiki esihlanzekile, esomile, nesihlala isikhathi eside esikhulu ngokwanele ukubamba impuphu ye-PAM edingekayo namanzi. Ungazisebenzisi izitsha zensimbi noma izitsha ezinezibazi zensimbi.
Engeza i-Solvent: Engeza inani elifanele lamanzi.
Ukuxuba: Qala i-stirrer. Uma uxuba, qiniseka ukuthi i-stirrer icwiliswe ngokuphelele esixazululweni ukuze ugweme amabhamuza. Ijubane lokuxuba akufanele libe phezulu kakhulu ukuze ugweme ukuphuka kwe-PAM molecular chain.
Faka i-PAM Powder: Faka kancane kancane i-PAM powder edingekayo esitsheni ngenkathi uvuselela kancane ukuze ugweme ukundiza kothuli. Qhubeka uvuselela ikhambi ukuze wenze i-PAM powder ihlakazeke ngokulinganayo ku-solvent.
Linda Ukuncibilika: Qhubeka uvuselela futhi ubheke ukuncibilika kwempuphu ye-PAM. Ngokuvamile, idinga ukuxutshwa ihora eli-1 kuya kwamabili kuze kube yilapho impuphu ye-PAM incibilika ngokuphelele.
Hlola Ukuncibilika: Ngemva kokuqedela ukuncibilika, thola ukuthi ngabe kuncibilike ngokuphelele yini ngokubheka ukucaca noma inkomba yokugqama kwesisombululo. Uma kuvela noma yiziphi izinhlayiya noma amaqoqo angancibiliki, qhubeka uvuselela kuze kube yilapho kuncibilika ngokuphelele. Uma isisindo sama-molecule se-PAM siphezulu kakhulu futhi ukuncibilika kuhamba kancane kakhulu, kungashiswa ngendlela efanele, kodwa akufanele kudlule ku-60°C.
Lungisa Isitsha Namathuluzi: Khetha isitsha esikhulu ngokwanele ukuqinisekisa ukuthi kunesikhala esanele sokuxuba. Yiba nesixubho noma induku yokuxuba ekulungele ukuqinisekisa ukuthi isixazululo sixubana kahle.
Lungisa Isixazululo: Engeza amanzi kanye ne-emulsion ye-PAM ngasikhathi sinye, bese uqala i-stirrer ngasikhathi sinye ukuqinisekisa ukuthi i-emulsion namanzi kuxutshwe ngokuphelele.
Lawula Ukuhlushwa Kokugcina: Ukuhlushwa kokugcina kwe-emulsion ye-PAM kufanele kulawulwe ku-1-5% ukuqinisekisa umphumela omuhle kakhulu we-flocculation. Uma udinga ukulungisa ukuhlushwa, qhubeka nokwengeza amanzi noma ukwandisa i-emulsion ye-PAM.
Qhubeka Uvuselela: Ngemva kokufaka i-emulsion ye-PAM, qhubeka uvuselela ikhambi imizuzu eyi-15-25. Lokhu kusiza ama-molecule e-PAM ukuthi ahlakazeke futhi ancibilike ngokugcwele, okuqinisekisa ukusatshalaliswa kwawo ngokulinganayo emanzini.
Gwema Ukuxuba Okudlulele: Nakuba ukuxuba okufanele kusiza ekuncibilikiseni i-PAM, ukuxuba okudlulele kungabangela ukuwohloka kwama-molecule e-PAM, kunciphise umphumela wayo wokugoqa. Ngakho-ke, lawula isivinini nesikhathi sokuxuba.
Ukugcina Nokusebenzisa: Gcina isixazululo se-PAM esincibilikisiwe endaweni emnyama, eyomile, uqinisekise ukuthi izinga lokushisa lifanelekile. Gwema ukukhanya kwelanga okuqondile ukuze uvimbele ukuwohloka kwe-PAM. Uma usebenzisa, qiniseka ukuthi isixazululo siyafana ukuze ugweme ukuthinta umphumela wokugobhoza ngenxa yokusatshalaliswa okungalingani.
