PROCESS FOR SIZING PAPER AND SIZING COMPOSITION |
摘要 |
The present invention relates to a process for sizing paper comprising providing an aqueous suspension comprising cellulosic fibres, dewatering said aqueous suspension thereby forming a paper web, said process comprising adding to the cellulosic suspension an aqueous composition comprising aggregates comprising a sizing agent , the composition obtainable by mixing in any order prior to the addition to the aqueous suspension, (i) an aqueous solution comprising at least one coagulation agent, and (ii) an aqueous dispersion comprising a sizing agent, wherein the zeta potential of the composition is less than 20 mV. The invention also refers to an aqueous sizing composition.
