Yadda za a inganta ingantaccen samarwa a cikin masana'antar yin takarda ta hanyar polyacrylamide

Polyacrylamideƙari ne da ake amfani da shi sosai a cikin masana'antar takarda. Polyacrylamide (PAM), a matsayin polymer mai narkewa da ruwa, yana da kyakkyawan flocculation, thickening, watsawa da sauran kaddarorin. Za a yi amfani da matakai daban-daban tare da ayyuka daban-daban. A cikin masana'antar yin takarda, PAM tana taka rawar da babu makawa. Ya kawo fa'idodin tattalin arziƙi ga masana'antar yin takarda ta hanyar haɓaka kaddarorin ɓangaren litattafan almara da haɓaka aikin injinan takarda.
