The Beater Addition of Polyvinylalcohol Resion
1961
The results of a study of the properties of paper treated with PVA powder by the beater addition are presented.Factors affecting the retention and the strength of the sheets are discussed including the rate of dissolution, particle size of the resin in the range of saponification degree 95.7-99.9%. The absorption water of the sheets are needed more than 60% before drying process.Major advantage was found in the use of PVA powder as beater addition for paper strength.
