Polyacrylamide(PAM), njenge-ejenti ebalulekileyo yokucoca amanzi, isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo zoshishino. Nangona kunjalo, ukuchithwa kwePAM kunokuba ngumngeni kubasebenzisi abaninzi. Iimveliso ze-PAM ezisetyenziswa kumanzi amdaka kwimizi-mveliso ziza ngeendlela ezimbini: umgubo owomileyo kunye ne-emulsion. Eli nqaku liza kwazisa indlela yokuchithwa kweentlobo ezimbini ze-PAM ngokucacileyo ukuqinisekisa ukuba abasebenzisi bafumana iziphumo ezilungileyo kwimisebenzi yangempela.
Polyacrylamide Umgubo owomileyo
Indlela yokucima ngokuthe ngqo yindlela elula kwaye ixhaphake kakhulu yokuchithwa kwePAM. Le ndlela ifanelekile kwi-PAM powder kunye nobunzima obuphantsi be-molecular kwaye kulula ukuyichitha. Nanga amanyathelo athile:
Lungiselela uMgqomo: Khetha isikhongozeli seplastiki esicocekileyo, esomileyo, esomeleleyo esikhulu ngokwaneleyo ukuba sibambe umgubo ofunekayo wePAM kunye namanzi. Musa ukusebenzisa izitya zentsimbi okanye izitya ezinamabala esinyithi.
Yongeza i-Solvent: Yongeza isixa esifanelekileyo samanzi.
Gqiba: Qalisa i-stirter. Xa uvuselela, qinisekisa ukuba i-stirrer ifakwe ngokupheleleyo kwisisombululo ukuphepha amaqamza. Isantya esishukumisayo akufanele sibe phezulu kakhulu ukuphepha ukuphulwa kwekhonkco le-molecular PAM.
Yongeza i-PAM Powder: Kancinci yongeza i-PAM powder efunekayo kwisitya ngelixa uvuselela ngobumnene ukuphepha uthuli oluphaphazelayo. Qhubeka uvuselela isisombululo ukwenza i-PAM powder ihlakazeke ngokulinganayo kwi-solvent.
Lindela ukuchithwa: Qhubeka uvuselela kwaye uqaphele ukuchithwa kwe-PAM powder. Ngokuqhelekileyo, kufuneka iqhutywe kwi-1 ukuya kwiiyure ze-2 de i-PAM powder ichithwe ngokupheleleyo.
Jonga i-Solubility: Emva kokugqiba ukuchithwa, qaphela ukuba iphelile ngokupheleleyo ngokujonga i-transparency okanye i-refractive index yesisombululo. Ukuba kukho amasuntswana anganyibilikiyo okanye i-clumps evelayo, qhubeka uvuselela de unyibilike ngokupheleleyo. Ukuba ubunzima be-molecular PAM buphezulu kakhulu kwaye ukuchithwa kucotha kakhulu, kunokufudumeza ngokufanelekileyo, kodwa akufanele kudlule i-60 ° C.
Lungiselela isikhongozeli kunye nezixhobo: Khetha isikhongozeli esikhulu ngokwaneleyo ukuqinisekisa ukuba kukho indawo eyaneleyo yokuxuba. Yiba ne-stirrer okanye i-sticker ekulungele ukuqinisekisa ukuba isisombululo sixutywa kakuhle.
Lungiselela iSicombululo: Yongeza amanzi kunye ne-PAM emulsion ngaxeshanye, kwaye uqale i-stirrer ngaxeshanye ukuqinisekisa ukuba i-emulsion kunye namanzi zixutywe ngokupheleleyo.
Lawula iNgcaciso yokuGqibela: Ukugxininiswa kokugqibela kwe-emulsion ye-PAM kufuneka ilawulwe kwi-1-5% ukuqinisekisa isiphumo esihle se-flocculation. Ukuba ufuna ukulungelelanisa ugxininiso, qhubeka ukongeza amanzi okanye ukwandisa i-emulsion ye-PAM.
Qhubeka uvuselela: Emva kokufaka i-emulsion ye-PAM, qhubeka uvuselela isisombululo se-15-25 imizuzu. Oku kunceda iimolekyuli zePAM zisasazeke ngokupheleleyo kwaye zinyibilike, ziqinisekisa ukusasazwa kwazo emanzini.
Gwema ukugqithisa okugqithisileyo: Nangona ukuvuselela okufanelekileyo kunceda ukunyibilikisa i-PAM, ukuvuselela ngokugqithiseleyo kunokubangela ukuthotywa kweeamolekyu ze-PAM, ukunciphisa umphumo wayo we-flocculation. Ngoko ke, lawula isantya kunye nexesha.
Ukugcinwa kunye nokuSebenzisa: Gcina isisombululo se-PAM esichithwe kwindawo emnyama, eyomileyo, uqinisekise ukuba ubushushu bufanelekile. Kuphephe ukukhanya kwelanga ngqo ukuthintela ukuthotywa kwePAM. Xa usebenzisa, qinisekisa ukufana kwesisombululo ukuphepha ukuchaphazela umphumo we-flocculation ngenxa yokusabalalisa okungafaniyo.
