Abstract

Kjemisk pulpeprosess som gjør bruk av et oksyalkylen-modifisert organopolysiloksan i kombinasjon med en alkylert sulfonert difenyloksid surfaktant som tilsetningsstoffer til den kjemiske pulpeprosess. Disse tilsetningsstoffer forbedrer overraskende de fysikalske egenskapene til trepulpen og produkter produsert fra denne.Chemical pulping process using an oxyalkylene-modified organopolysiloxane in combination with an alkylated sulfonated diphenyl oxide surfactant as additives to the chemical pulping process. These additives surprisingly improve the physical properties of the wood pulp and products produced from it.
