Indlela yokongeza i-PAM

I-Polyacrylamide (PAM) yi-polymer ethe tyaba ene-flocculation, adhesion, i-drag reduction, kunye nezinye iimpawu.I-Polymer Organic Flocculant, isetyenziswa kakhulu kwicandelo lokunyanga amanzi. Xa usebenzisa i-PAM, kufuneka kulandelwe iindlela zokusebenza ezichanekileyo ukuze kuthintelwe ukuchithwa kweekhemikhali.

Inkqubo yokongeza i-PAM

NgokubaI-PAM eqinileyo, kufuneka yongezwe emanzini emva kokuba inyibilikisiwe. Kwiimpawu zamanzi ezahlukeneyo, kufuneka kukhethwe iintlobo ezahlukeneyo ze-PAM, kwaye izisombululo zilinganiswe ngokwamanqanaba ahlukeneyo. Xa kufakwa i-polyacrylamide, kufuneka kuqwalaselwe la manqaku alandelayo:

Uvavanyo lweeJar:Chonga iinkcukacha kunye nomlinganiselo ongcono ngokusebenzisa iimvavanyo zebhotile. Kuvavanyo lwebhotile, yonyusa kancinci idosi yepolyacrylamide, jonga isiphumo se-flocculation, kwaye umisele idosi efanelekileyo.

Ukulungiselela i-PAM Aqueous Solution:Ekubeni i-anionic PAM (APAM) kunye ne-nonionic PAM (NPAM) zinobunzima obuphezulu beemolekyuli kunye namandla aqinileyo, i-anionic polyacrylamide idla ngokwenziwa ibe yisisombululo samanzi esinoxinzelelo lwe-0.1% (ngokubhekiselele kumxholo oqinileyo) kunye namanzi acocekileyo angenatyuwa. Khetha iibhakethi ze-aluminium ezifakwe i-enamel, ezigalelwe i-galvanized, okanye zeplastiki endaweni yezikhongozeli zesinyithi njengoko ii-ion zesinyithi zivuselela ukuwohloka kweekhemikhali ze-PAM yonke. Ngexesha lokulungiselela, i-polyacrylamide kufuneka ifefwe ngokulinganayo emanzini axutywayo kwaye ifudunyezwe ngokufanelekileyo (<60°C) ukuze kukhawuleziswe ukunyibilika. Xa inyibilika, kufuneka kunikwe ingqalelo ekufakeni imveliso ngokulinganayo nangokucothayo kwisinyibilikisi ngemilinganiselo yokuxuba nokufudumeza ukuze kuthintelwe ukuqina. Isisombululo kufuneka silungiswe kubushushu obufanelekileyo, kwaye kufuneka kuphetshwe ukucheba oomatshini ixesha elide nokunzima. Kucetyiswa ukuba umxube ujikeleze kwi-60-200 rpm; kungenjalo, kuya kubangela ukuwohloka kwe-polymer kwaye kuchaphazele isiphumo sokusetyenziswa. Qaphela ukuba isisombululo samanzi se-PAM kufuneka silungiswe kwangoko ngaphambi kokusetyenziswa. Ukugcinwa kwexesha elide kuya kukhokelela ekunciphiseni kancinci kokusebenza. Emva kokongeza isisombululo samanzi esithambileyo kwi-suspension, ukuxuba ngamandla ixesha elide kuya kutshabalalisa ii-flocs ezenziweyo.

Iimfuneko zokulinganisa:Sebenzisa isixhobo sokulinganisa ukongeza i-PAM. Kwinqanaba lokuqala lokusabela kokongeza i-PAM, kuyimfuneko ukwandisa amathuba okudibana kweekhemikhali namanzi ukuze kunyangwe kangangoko kunokwenzeka, kunyuswe ukuxukuxa, okanye kunyuswe izinga lokuhamba kwamanzi.

Izinto ekufuneka uziqaphele xa ufaka i-PAM

Ixesha Lokuchithwa:Iintlobo ezahlukeneyo ze-PAM zinamaxesha ahlukeneyo okunyibilika. I-Cationic PAM inexesha elifutshane lokunyibilika, ngelixa i-anionic kunye ne-nonion PAM zinexesha elide lokunyibilika. Ukukhetha ixesha elifanelekileyo lokunyibilika kunokunceda ukuphucula isiphumo se-flocculation.

Idosi kunye noQokelelo:Umlinganiselo ofanelekileyo ngundoqo ekufezekiseni isiphumo esihle kakhulu sokuqunjelwa. Umlinganiselo ogqithisileyo unokubangela ukujiya okugqithisileyo kwee-colloids kunye namasuntswana axhonyiweyo, okwenza i-sediment enkulu endaweni yee-flocs, ngaloo ndlela ichaphazela umgangatho womjelo ongcolileyo.

Iimeko zokuxuba:Ukuqinisekisa ukuxuba okwaneleyo kwe-PAM kunye namanzi amdaka, kufuneka kukhethwe izixhobo zokuxuba ezifanelekileyo kunye neendlela. Ukuxuba okungalinganiyo kunokubangela ukuba i-PAM inyibilike ngokupheleleyo, nto leyo echaphazela impembelelo yayo yokuqunjelwa.

Iimeko Zokusingqongileyo Kwamanzi:Izinto ezikwimo engqongileyo ezifana nexabiso le-pH, ubushushu, uxinzelelo, njl.njl., nazo ziya kuchaphazela isiphumo se-flocculation se-PAM. Ngokuxhomekeke kwiimeko zomgangatho wamanzi amdaka, ezi parameters zinokufuna ukulungiswa ukuze kufunyanwe iziphumo ezilungileyo.

Ulandelelwano lweDosa:Kwinkqubo yokudosa enee-arhente ezininzi, kubalulekile ukuqonda ulandelelwano lwedosa lwee-arhente ezahlukeneyo. Ulandelelwano olungalunganga lwedosa lunokuchaphazela ukusebenzisana phakathi kwe-PAM kunye nee-colloids kunye nee-smilled particles, ngaloo ndlela zichaphazela isiphumo se-flocculation.

I-Polyacrylamide(PAM) yipolymer eguquguqukayo enezicelo ezahlukeneyo, ngakumbi ekunyangweni kwamanzi. Ukuze isebenze kakuhle kwaye iphephe ukuchitha imali, kubalulekile ukulandela iinkqubo ezifanelekileyo zokusebenza. Ngokuqwalasela ngononophelo izinto ezifana nexesha lokunyibilika, idosi, iimeko zokuxuba, iimeko zokusingqongileyo kwamanzi, kunye nolandelelwano lwedosi, ungasebenzisa iPAM ngokufanelekileyo ukufezekisa iziphumo zokuqunjelwa ezinqwenelekayo kunye nokuphucula umgangatho wamanzi.
