Cov khoom siv polyacrylamide puas siv tau? Kuv yuav siv cov khoom no li cas?
Polyacrylamide yog linear organic siab molecular polymer, thiab nws kuj yog ib tug siab molecular dej kho flocculant khoom, uas muaj peev xwm tshwj xeeb absorbed hais nyob rau hauv dej, ua raws li ib tug choj ntawm hais, thiab ua zoo hais ua ib tug kuj loj flocs thiab ceev sedimentation. Cov txheej txheem no hu ua flocculation, vim nws cov nyhuv flocculation zoo, PAM yog siv los ua flocculant hauv kev kho dej thiab siv dav hauv kev kho dej phwj.
yuav siv li cas:
(1) Polyacrylamide qhuav hmoov lossis polyacrylamide emulsion feem ntau tsis tuaj yeem siv ncaj qha. Nws yuav tsum tau diluted thiab yaj nrog dej raws li ib qho kev faib ua feem, thiab ces siv tom qab dissolution tiav;
(2) Cov dej rau dissolving cov khoom polyacrylamide yuav tsum yog cov dej huv huv, tsis yog dej phwj tuaj;
(3) Ntsuas cov khoom siv polyacrylamide uas yuav tsum tau yaj, thiab qhov kev sib cais feem ntau yog 0.1 feem pua -0.3 feem pua ;
(4) Yuav tsum muaj lub pas dej sib tov ntawm qhov chaw siv, thiab yuav tsum muaj cov khoom sib tov. Lub stirring ceev yog 60-200 rpm/mg. Cov khoom tawg thiab nplawm tsis tuaj yeem ua los ntawm hlau, thiab hlau ions yuav ua rau cov khoom degradation;
(5) Lub sijhawm nplawm yog 40-60 feeb, thiab cov kua dej yaj yog cov pob tshab, tsis muaj xim viscous;
(6) Ntxiv cov tshuaj tov rau hauv cov kav dej uas yuav tsum tau kho, sib tov kom huv si, thiab thaum kawg flocculate rau hauv agglomerates thiab nyob rau hauv dej, thiab cov cement sib cais.
