Abstract

Materialer og fremgangsmåter Det beskrives materialer og fremgangsmåter for inhibering av avleiring av organiske forurensninger fra masse på overflater i masse- og papirfremstillings- systemer. Materiale er en kombinasjon av en polyvinyl- alkohol som har fra 50 til 100% hydrolyse og en gelatin av hcay molekylvekt som har en molekylvekt på ca. 100.000 eller høyere og som tilsettes til masse eller sprayes på overflater i masse- og papirfremstillingssystemer. I et foretrakker utførelseseksempel demonstreres syergisme ved et 8:1-vektforhold av polyvinylalkohol til gelatin av høy molekylvekt.
