Progress in Organic Coatings , , Progress in Organic Coatings , 77 4 , This result confirmed that nanoscale starch was successfully prepared by the twin-screw extrusion and the crosslinking agent was very important for the preparation of nanostarch. Journal of Colloid and Interface Science , , Wei, B. In this work, the influences of starch on latex migration and on properties of model clay coatings were investigated, in order to better understand interactions between starch and latex and their effects on coating structure development.
The influence of starch-based bio-latex on paper coating
Main article: Coated paper. Comments 0. Sodium tripolyphosphate. This is especially important in tissue paper. Typical chemicals used include cationic starch and polyacrylamide PAM derivatives. Makeup chemical in sulfate pulping chemical recovery Na 2 SO 4. Chemistry portal.

Starch has a similar chemical structure as the cellulose fibre of the pulp, and the surface of both the starch and fibre are negatively charged. Quaternary salts that are used include 2.
Description: It thus increases the brightness of the material when the illumination includes ultraviolet radiation. Caustic soda is added to increase the pH in the pulping process of fibers. Please consider expanding the lead to provide an accessible overview of all important aspects of the article. Mineral fillers are used to lower the consumption of more expensive binder material or to improve some properties of the paper. CS1 maint: uses authors parameter link.
