Polyacrylamide flocculants yog dav siv nyob rau hauv kev lag luam papermaking los txhim kho daim ntawv zoo, pulp dewatering kev ua tau zoo, tuav cov fibers zoo thiab muab tub lim, thiab txo cov khoom siv raw thiab ib puag ncig muaj kuab paug. Nws tuaj yeem siv los ua ib qho dispersant los txhim kho cov ntawv sib xws.
Daim ntawv thov ntawm polyacrylamide flocculants hauv kev lag luam papermaking feem ntau suav nrog ob yam:
Ua ntej, kev txhim kho tus nqi khaws cia ntawm cov fillers thiab pigments, txo qhov poob ntawm raw khoom thiab ib puag ncig muaj kuab paug.
Qhov thib ob yog los txhim kho lub zog ntawm daim ntawv. Ntxiv polyacrylamide rau daim ntawv tuaj yeem txhim kho tus nqi khaws cia ntawm cov fibers zoo thiab muab cov khoom tso rau ntawm lub mesh, ua kom lub cev qhuav dej ntawm daim ntawv. Kev tsim ntawm flocculation tuaj yeem ua rau cov dej hauv cov ntaub ntawv lim tau yooj yim dua, txo cov fiber ntau hauv dej dawb, txo cov pa phem ib puag ncig, thiab txhim kho kev pom thiab pom kev ua haujlwm zoo.
