Kev ceev faj rau polyacrylamide hauv thee ntxuav:
1. Rau kev kho cov thee slime cov dej khib nyiab, polyacrylamide PAM rau cov thee ntxuav yuav tsum tau ntxiv rau qhov tsim nyog kom ua tau zoo rau nws cov nyhuv flocculation. Nws tuaj yeem txiav txim siab los ntawm cov kev sim ua raws li cov txheej txheem xaiv cov coal slime water treatment thiab thee slime water properties. Kev siv me me yuav ua rau qeeb qeeb ntawm cov coal slime sedimentation, thiab cov concentrated overflow muaj feem ntau yuav dhau tus qauv, thiab qhov yuav tsum tau muaj cov dej ntsuas ntsuas tsis tuaj yeem lav.
2. Kev siv ntau dhau, txawm hais tias nws ua kom cov sedimentation tus nqi ntawm cov coal slime, yog ib qho yooj yim ua rau cov concentration ntawm concentrated underflow siab dhau. Kev noj ntau dhau qee zaum ua rau cov concentration ntawm cov piam thaj hauv qab siab txog li 700g / L lossis ntau dua, thiab cov ntsiab lus ntawm polyacrylamide hauv cov dej hauv qab nce ntxiv, uas tsis zoo rau kev thauj mus los hauv qab thiab lim xovxwm. Thaum unloading thee ncuav mog qab zib thaum lub sij hawm lim xovxwm, nws tsis yooj yim rau poob, uas kuj ua rau pov tseg ntawm reagents. Feem ntau, cov concentration ntawm concentrated underflow yuav tsum yog 500g / L, uas muaj peev xwm ua tau raws li lub lim pressing ntau lawm.
3. Polyacrylamide rau cov thee ntxuav yuav tsum tau ua kom zoo dispersed thiab ua tib zoo yaj kom tsis txhob muaj adhesion ntawm cov khoom vim tias cov hmoov tawg sai sai, ua rau "ntses qhov muag" tsis tuaj yeem yaj hauv cov khoom.
4. Lub cia ruaj khov ntawm yaj flocculants tsis zoo thiab lawv yuav tsum tau siv nyob rau hauv 24 teev tom qab dissolution. Yog tias qhov viscosity txo qis tom qab 2-3 hnub, txoj haujlwm yuav raug txo.
