摘要:
A one-pass, non-tolerance dependent method for preparing paper size emulsions comprising an aqueous emulsion of a substituted cyclic dicarboxylic anhydride, a colloidal stabilizer, and a surfactant wherein the emulsion after one-pass through a dispersion system has an average particle size of less than 2 microns.
摘要:
A size mixture comprising a higher organic ketene dimer and polyoxyalkylene alkyl or alkyl-aryl ether or the corresponding mono- or di-ester is used to size paper products. In accordance with a preferred embodiment the liquid size mixture is added directly to the paper stock system without prior emulsification.
摘要:
A size mixture comprising a substituted cyclic dicarboxylic acid anhydride and polyoxyalkylene alkyl or alkyl-aryl ether or the corresponding mono- or di-ester is used to size paper products. In accordance with a preferred embodiment the liquid size mixture is added directly to the paper stock system without prior emulsification.
摘要:
A method for preparing hydrophobic starch derivatives wherein starch and an anhydride are reacted in a slurry with the anhydride reagent being added to the slurry in pre-emulsified form to provide a significantly faster and more efficient reaction.
