Starch oxidation and study of changing its properties for use as an adhesive component for the production of corrugated cardboard

It is known that for sizing papers and cardboards, starch is required, which has a lower viscosity compared to natural, increased stability and increased binding capacity. This is necessary so that the starch dispersions in the size press have a sufficiently high concentration, are process able and remain stable. The choice of an oxidizing agent and the conditions for the method of oxidizing corn starch are theoretically substantiated. The mechanism and regularities of the process of starch oxidation have been studied. Changes in the gel-forming and sorption properties of starch during its oxidation were revealed. The intervals of quantitative parameters of the components for the modification process are determined. The dependence of the surface tension of starch pastes on its concentration in solution has been obtained.
