<p>A process for the continuous production of starch corrugating pastes which comprises the steps of slurrying natural or non-gelatinised starch in water to provide a starch suspension, continuously gelatinising a first portion of said starch suspension by contacting with excess alkaline agent, continuously mixing the gelatinised first starch portion with a second portion of said starch suspension, and continuously neutralizing a portion of the excess alkali present in the gelatinised starch with boric acid. The process obviates disadvantages in prior art processes, including high viscosity in primary pastes, difficulty in adapting to continuous production, lack of flexibility in the choice of paste formulations and lack of stability in the pastes resulting in change in viscosity and imperfect pasting of the cardboard.</p> |
