Test of paper making auxiliary agent composition
What is papermaking auxiliary agent?
Paper making industry is a chemical processing industry using fiber as raw material. Chemical auxiliary which can give paper all excellent performance is indispensable in the processes of pulping, papermaking and paper processing. Based on its purpose, the auxiliary agent falls roughly into 4 categories which are pulping auxiliary, papermaking auxiliary, coating auxiliary and other relevant auxiliaries.
