What are the different effects of beating on the different properties of paper sheet?
Pulp beating is the basic step in paper making process, so what are the different effects of beating on the different properties of the sheet? 1.Binding force: Rise 2.Splitting length: First increase (beating degree at 70 ° SR (wood pulp) 50 ° SR (grass)) reaches the highest, then decrease. 3.Bursting degree; About 50 ° SR reached the highest, then decreased; 4.Folding resistance: Rise first and then decrease 5.Tearing strength: Rise first and then fall; 6.Tightness: Rise; 7.Opacity: Decrease; 8.Elongation and flexibility: Rise; 9.Absorptivity and air permeability: Drop; 10.Brittleness: Drop first and then rise. Thus it can be seen, pulp beating has great effect on finished paper properties, so the paper pulping process must be attentioned.
