摘要

Suspensions and solutions of substances in liquids, especially aqueous suspensions of starch which have been stabilised by addition of a minor amount of a hydrophilic polymeric viscosity-increasing agent such as xanthan gum, are applied to paper or board during manufacture, by using a rotary atomiser and allowing the spray discharged therefrom to fall on the surface of the paper or board moving relatively to the atomiser.
