I-Polyacrylamide(PAM), njengesixhobo esibalulekileyo sokucoca amanzi, isetyenziswa kakhulu kwiindawo ezahlukeneyo zoshishino. Nangona kunjalo, ukunyibilikisa i-PAM kunokuba ngumceli mngeni kubasebenzisi abaninzi. Iimveliso ze-PAM ezisetyenziswa kumanzi amdaka zoshishino ziza ngeendlela ezimbini: umgubo owomileyo kunye ne-emulsion. Eli nqaku liza kwazisa indlela yokunyibilikisa iintlobo ezimbini ze-PAM ngokweenkcukacha ukuqinisekisa ukuba abasebenzisi bafumana iziphumo ezilungileyo kwimisebenzi yokwenyani.
Umgubo owomileyo wePolyacrylamide
Indlela yokunyibilikisa ngokuthe ngqo yeyona ndlela ilula neqhelekileyo yokunyibilikisa i-PAM. Le ndlela ifanelekile kwi-PAM powder enobunzima obuphantsi beemolekyuli kwaye kulula ukuyinyibilikisa. Nazi amanyathelo athile:
Lungisa Isikhongozeli: Khetha isitya seplastiki esicocekileyo, esomileyo, nesihlala ixesha elide esikhulu ngokwaneleyo ukuba sibambe umgubo we-PAM namanzi afunekayo. Musa ukusebenzisa izikhongozeli zesinyithi okanye izikhongozeli ezineziphene zesinyithi.
Yongeza iSolvent: Yongeza umlinganiselo ofanelekileyo wamanzi.
Ukuxuba: Qalisa i-stirrer. Xa uxuba, qiniseka ukuba i-stirrer intywiliswe ngokupheleleyo kwisisombululo ukuze kuthintelwe amaqamza. Isantya sokuxuba akufuneki sibe phezulu kakhulu ukuze kuthintelwe ukwaphuka kwekhonkco le-molecular ye-PAM.
Yongeza i-PAM Powder: Yongeza kancinci i-PAM powder efunekayo kwisikhongozeli ngelixa uvuselela kancinci ukuze uphephe ukubhabha kothuli. Qhubeka uvuselela isisombululo ukuze i-PAM powder isasazeke ngokulinganayo kwi-solvent.
Lindela Ukunyibilika: Qhubeka uvuselela kwaye ujonge ukunyibilika komgubo we-PAM. Ngokwesiqhelo, kufuneka uxutywe kangangeyure e-1 ukuya kwezi-2 ude unyibilike ngokupheleleyo umgubo we-PAM.
Jonga ukunyibilika: Emva kokugqiba ukunyibilika, qinisekisa ukuba inyibilike ngokupheleleyo na ngokujonga ukucaca okanye isalathisi sokuchacha kwesisombululo. Ukuba kukho naziphi na iisuntswana okanye amaqhuqhuva anganyibilikanga, qhubeka uvuselela ude unyibilike ngokupheleleyo. Ukuba ubunzima be-molecular ye-PAM buphezulu kakhulu kwaye ukunyibilika kuhamba kancinci, kungafudunyezwa ngokufanelekileyo, kodwa akufuneki kudlule kuma-60°C.
Lungisa iSikhongozeli kunye nezixhobo: Khetha isitya esikhulu ngokwaneleyo ukuqinisekisa ukuba kukho indawo eyaneleyo yokuxuba. Yiba nesixongozeli okanye intonga yokuxuba elungele ukuqinisekisa ukuba isisombululo sixutywa kakuhle.
Lungisa iSisombululo: Yongeza amanzi kunye ne-emulsion ye-PAM ngaxeshanye, kwaye uqalise i-stirrer ngaxeshanye ukuqinisekisa ukuba i-emulsion kunye namanzi zixutywe ngokupheleleyo.
Lawula Uxinzelelo Lokugqibela: Uxinzelelo lokugqibela lwe-emulsion ye-PAM kufuneka lulawulwe kwi-1-5% ukuqinisekisa isiphumo esihle kakhulu se-flocculation. Ukuba ufuna ukulungisa uxinzelelo, qhubeka ukongeza amanzi okanye unyuse i-emulsion ye-PAM.
Qhubeka Uxuba: Emva kokongeza i-emulsion ye-PAM, qhubeka uxuba isisombululo imizuzu eli-15-25. Oku kunceda iimolekyuli ze-PAM zisasazeke ngokupheleleyo kwaye zinyibilike, ukuqinisekisa ukuba zisasazeke ngokulinganayo emanzini.
Kuphephe Ukuxukuxa Ngokugqithisileyo: Nangona ukuxukuxa ngokufanelekileyo kunceda ekunyibilikiseni i-PAM, ukuxukuxa ngokugqithisileyo kunokubangela ukuwohloka kweemolekyuli ze-PAM, kunciphisa impembelelo yayo yokuqukuqela. Ngoko ke, lawula isantya kunye nexesha lokuxukuxa.
Ukugcinwa Nokusetyenziswa: Gcina isisombululo se-PAM esinyibilikisiweyo kwindawo emnyama, eyomileyo, uqinisekise ukuba ubushushu bufanelekile. Kuphephe ukukhanya kwelanga ngqo ukuze uthintele ukubola kwe-PAM. Xa usebenzisa, qinisekisa ukuba isisombululo siyafana ukuze uphephe ukuphazamisa impembelelo yokuqunjelwa ngenxa yokusasazwa okungalinganiyo.
