Polyacrylamide
Polyacrylamide yog cov kab polymer, cov khoom lag luam tsuas yog muab faib ua hmoov qhuav thiab colloidal ob daim ntawv. Raws li nws qhov nruab nrab molecular phaus, nws muaj peev xwm muab faib ua qhov hnyav molecular (<1 lab), qhov nruab nrab molecular phaus (2 ~ 4 lab) thiab siab molecular phaus (> .7 lab) .Txawm nws cov qauv tuaj yeem faib ua tsis - ionic, anion thiab cationic. Kev ua dej tsis sib haum (HPAM) ntawm cov tshuaj anion. Cov saw tseem ceeb ntawm polyacrylamide muaj ntau pawg amide, nrog cov kev ua haujlwm siab, thiab tuaj yeem hloov kho los tsim ntau cov khoom siv ntawm polyacrylamide. Cov khoom lag luam tau siv dav hauv papermaking, ua cov ntxhia, roj ntxiv, metallurgy, cov ntaub ntawv hauv tsev, kho dej phwj thiab lwm yam kev lag luam. Raws li cov khoom siv roj nplua nyeem, tus neeg sawv cev ua haujlwm, av nplaum stabilizer, roj hloov chaw, tus neeg ua haujlwm txo cov dej hauv tus neeg sawv cev thiab cov kab mob ua rau tus neeg sawv cev, polyacrylamide tau siv dav hauv drilling, acidification, fracturing, txhaws dej, cementing, roj thib ob rov qab thiab roj rov qab.

Thov
1. luam tawm thiab dyeing kev kho dej khib nyiab
Kev luam ntawv thiab dyeing kev kho dej khib nyiab, hloov ntawm cov tshuaj txau ua kua roj me me, txheeb ze rau cov tshuaj loj ntawm cov coagulant, cov coagulation efficiency yog qhov siab, zoo tshaj plaws ph yam raws li: 8.0.
2.Qhov khoom siv dej khib nyiab kho
Cov txheej txheem dej khib nyiab kho, uas yog siv los ua coagulant tsis txhob siv cov polyaluminium chloride, aluminium sulfate, thiab lwm yam, kuj tuaj yeem siv ua dewatering ntawm papermaking sludge.
