Cim npe

Polyacrylamide yog linear polymer, cov khoom yog muab faib ua cov hmoov qhuav thiab colloidal ob daim ntawv. Raws li nws qhov hnyav molecular, nws tuaj yeem muab faib ua qhov hnyav molecular (<1 lab), nruab nrab molecular hnyav (2 ~ 4 lab) thiab siab molecular hnyav (>.7 lab). - ionic, anion thiab cationic. Dej disintegration (HPAM) ntawm hom anion. Cov saw tseem ceeb ntawm polyacrylamide muaj ntau pawg amide, nrog rau cov tshuaj lom neeg ua haujlwm siab, thiab tuaj yeem hloov kho kom tsim tau ntau yam derivatives ntawm polyacrylamide. Cov khoom tau siv dav hauv papermaking, ntxhia ua, roj extraction, metallurgy, tsev cov ntaub ntawv, dej phwj tuaj kho thiab lwm yam lag luam. Raws li ib tug lubricant, ncua kev kawm ntawv tus neeg saib xyuas, av nplaum stabilizer, roj hloov chaw, dej tsis txo tus neeg saib xyuas thiab thickening tus neeg saib xyuas, polyacrylamide tau lug siv nyob rau hauv drilling, acidification, fracturing, dej plugging, cementing, theem nrab roj rov qab thiab tertiary roj rov qab.
