Polyacrylamide(PAM) feem ntau yog siv rau hauv cov chaw tsim hluav taws xob hauv cov chaw hauv qab no:
Flocculation: Thaum lub sijhawm ntxuav cov thee, cov thee muaj cov khoom zoo thiab cov impurities xws li av, pob zeb tawg, thiab cov organic teeb meem. Ua raws li flocculant, PAM nce qhov loj me ntawm cov khib nyiab tshem tawm, txhawb lawv cov kev sib sau ua ke rau hauv cov flocs loj dua uas nyob thiab sib cais yooj yim dua, yog li txhim kho thee ntxhua khaub ncaws.
Kev kho dej khib nyiab: Cov dej khib nyiab tsim tawm thaum lub sij hawm ntxuav cov coal feem ntau muaj cov ntsiab lus siab ntawm cov khoom thiab cov organic teeb meem. PAM ua haujlwm raws li flocculant kom sib sau cov khoom tshem tawm mus rau hauv cov flocs loj dua -pab kom cov sedimentation thiab filtration- thiab yog li ntxuav cov dej khib nyiab.
Slurry Dewatering: Muaj ntau cov thee slurry los yog tailings yog tsim thaum lub sij hawm thee ntxuav. PAM ua raws li tus neeg sawv cev dewatering; Thaum ntxiv rau cov slurry, nws ua rau kom cov khoom muaj zog thiab txo cov dej noo, ua rau cov txheej txheem tom ntej thiab pov tseg yooj yim dua.
Coal Surface Modification: PAM tuaj yeem adsorb rau ntawm qhov chaw thee, hloov nws cov khoom saum npoo los txhim kho flotation kev ua tau zoo thiab txhim khu kev ua tau zoo ntawm cov txheej txheem ntxuav thiab sib cais.
Thaum siv PAM, kev xaiv thiab kev tswj kom tsim nyog yuav tsum tau ua raws li cov txheej txheem ntxuav cov thee thiab cov yam ntxwv ntawm cov thee. Tsis tas li ntawd, kev siv tshuaj thiab kev kho mob yuav tsum tau hloov kho raws li cov dej khib nyiab thiab cov txiaj ntsig kev kho mob xav tau kom ua tiav cov txiaj ntsig zoo hauv kev ntxuav cov thee thiab kev kho dej khib nyiab.
