Uyongeza njani iPAM

I-Polyacrylamide (PAM) i-polymer yomgca kunye ne-flocculation, i-adhesion, ukunciphisa ukudonsa, kunye nezinye iimpawu. NjengePolymer Organic Flocculant, isetyenziswa ngokubanzi kwintsimi yonyango lwamanzi. Xa usebenzisa i-PAM, iindlela ezichanekileyo zokusebenza kufuneka zilandelwe ukuphepha ukuchithwa kweekhemikhali.

PAM Ukongeza Inkqubo

KubaI-PAM eqinile, kufuneka ifakwe emanzini emva kokuchithwa. Kwiimpawu zamanzi ezahlukeneyo, iintlobo ezahlukeneyo ze-PAM kufuneka zikhethwe, kunye nezisombululo zilungelelaniswe kwiindawo ezahlukeneyo. Xa ufaka i-polyacrylamide, ingqalelo kufuneka ihlawulwe kula manqaku alandelayo:

Iimvavanyo zeJar:Qinisekisa ezona nkcazo kunye nedosi ngovavanyo lwejagi. Kuvavanyo lwejagi, ngokuthe ngcembe wandise idosi ye-polyacrylamide, jonga isiphumo se-flocculation, kwaye umisele idosi efanelekileyo.

Ukulungiselela isisombululo sePAM samanzi:Ekubeni i-anionic PAM (APAM) kunye ne-nonionic PAM (NPAM) inobunzima obuphezulu be-molecular kunye namandla anamandla, i-anionic polyacrylamide idla ngokuqulunqwa kwisisombululo se-aqueous kunye ne-concentration ye-0.1% (ebhekisela kumxholo oqinileyo) kunye netyuwa, amanzi acocekileyo angathathi hlangothi. Khetha i-enameled, i-aluminiyam, okanye ii-emele zeplastiki endaweni yezikhongozeli zentsimbi njengoko ii-ion zentsimbi zibangela ukuthotywa kweekhemikhali zayo yonke iPAM. Ngethuba lokulungiselela, i-polyacrylamide idinga ukufafazwa ngokulinganayo emanzini avuselelayo kwaye ishushu ngokufanelekileyo (<60 ° C) ukukhawulezisa ukuchithwa. Xa ukuchithwa, kufuneka kuhlawulwe ingqalelo yokongeza imveliso ngokulinganayo kwaye ngokukhawuleza kwi-disolver kunye nemilinganiselo yokuvuselela kunye nokufudumala ukuphepha ukuqina. Isisombululo kufuneka silungiselelwe kwiqondo lokushisa elifanelekileyo, kwaye ukucheba kwexesha elide kunye nokuqina komatshini kufuneka kugwenywe. Kunconywa ukuba umxube ujikeleze kwi-60-200 rpm; ngaphandle koko, kuya kubangela ukuthotywa kwepolymer kwaye kuchaphazele umphumo wokusetyenziswa. Qaphela ukuba isisombululo se-PAM samanzi kufuneka silungiswe ngokukhawuleza ngaphambi kokusetyenziswa. Ukugcinwa kwexesha elide kuya kukhokelela ekunciphiseni ngokuthe ngcembe ukusebenza. Emva kokongeza isisombululo se-flocculant aqueous ekumisweni, ukuvuselela ngamandla ixesha elide kuya kutshabalalisa i-flocs eyenziwe.

IiMfuno zokuThatha:Sebenzisa isixhobo sokudosa ukongeza iPAM. Kwinqanaba lokuqala lokuphendula ukongeza i-PAM, kuyimfuneko ukwandisa amathuba oqhagamshelwano phakathi kweekhemikhali kunye namanzi ukuba aphathwe ngokusemandleni, ukwandisa ukuvuselela, okanye ukwandisa izinga lokuhamba.

Izinto ekufuneka uziqwalasele xa uFaka iPAM

Ixesha Lokupheliswa:Iindidi ezahlukeneyo zePAM zinamaxesha ahlukeneyo okuchithwa. I-Cationic PAM inexesha elifutshane lokuchithwa, ngelixa i-anionic kunye ne-nonionic PAM inexesha elide lokuchithwa. Ukukhetha ixesha elifanelekileyo lokuchithwa kunokunceda ukuphucula umphumo we-flocculation.

Umthamo kunye nokuQwalasela:Idosi efanelekileyo isitshixo ekufezekiseni eyona mpembelelo ilungileyo ye-flocculation. Ukugqithiswa kwedosi kunokubangela ukudityaniswa okugqithisileyo kwee-colloids kunye namasuntswana anqunyanyisiweyo, enze intlenga enkulu endaweni yeeflocs, ngaloo ndlela ichaphazele umgangatho wamanzi amdaka.

Iimeko Zokuxuba:Ukuqinisekisa ukuxuba okwaneleyo kwe-PAM kunye namanzi amdaka, izixhobo ezifanelekileyo zokuxuba kunye neendlela kufuneka zikhethwe. Ukuxuba okungafaniyo kunokubangela ukuchithwa okungaphelelanga kwe-PAM, ngaloo ndlela kuchaphazela umphumo wayo we-flocculation.

IiMeko zokusiNgqongileyo zaManzi:Izinto ezisingqongileyo ezifana nexabiso le-pH, ukushisa, uxinzelelo, njl., Kuya kuchaphazela kwakhona umphumo we-flocculation we-PAM. Ngokuxhomekeke kwiimeko zomgangatho wamanzi amdaka, ezi parameters zinokufuna uhlengahlengiso kwiziphumo ezizezona zilungileyo.

Ulandelelwano lweThamo:Kwinkqubo yedosi yee-arhente ezininzi, kubalulekile ukuqonda ulandelelwano lwedosi yee-arhente ezahlukeneyo. Ukulandelelana kwe-dosing engalunganga kunokuchaphazela ukusebenzisana phakathi kwe-PAM kunye ne-colloids kunye neengqungquthela ezimisiweyo, ngaloo ndlela zichaphazela umphumo we-flocculation.

Polyacrylamide(PAM) yipolymer eguquguqukayo enezicelo ezahlukeneyo, ngakumbi kunyango lwamanzi. Ukwandisa ukusebenza kwayo kwaye ugweme inkcitho, kubalulekile ukulandela iinkqubo ezifanelekileyo zokusebenza. Ngokuqwalasela ngononophelo izinto ezifana nexesha lokuchithwa, idosi, iimeko zokuxuba, iimeko zokusingqongileyo zamanzi, kunye nolandelelwano lwedosi, ungasebenzisa ngokufanelekileyo i-PAM ukufezekisa iziphumo ezinqwenelekayo ze-flocculation kunye nokuphucula umgangatho wamanzi.
