Abstract

For å hindre uønsket skumdannelse ved papirfremstilling anvendes det tilberedninger inneholdende a) fettsyrelaverealkylestere, b) hydrofoberte kieselsyrer og c) silikonforbindelser, som avskummere ved papirfremstilling. Blandingene er frie for amidforbindelser og paraffinhydrokarboner og oppviser i forhold til den kjente teknikk forbedrede egenskaper hva angår avskummervirkning og manglende dannelse av uønskede oljefaser.In order to prevent undesirable foaming in papermaking, preparations containing a) fatty acid lower alkyl esters, b) hydrophobic silicas and c) silicone compounds are used as foams in papermaking. The compositions are free of amide compounds and paraffin hydrocarbons and exhibit improved properties in terms of the foaming action and non-formation of undesirable oil phases relative to the prior art.
