Changes in Paper Properties under High Consistency Beating
- Fiber Length.
The length of fiber directly reflects the cutting degree of fiber during beating. When doing low concentration beating, the blade cuts off each fiber, so the more cutting, the shorter fiber is. The high-concentration beating mainly relies on the friction inside the paper material, so the cutting is less and the fiber is longer. - Crack Length and Breaking Resistance.
Crack length and breaking resistance are the main indicators to measure the paper strength. The length of paper crack and the increase of breaking resistance depend on the increase of fiber binding force. While the increase of fiber binding force depends on the increase of fiber surface and the degree of beating of paper. Under the condition of the same beating degree, with the increase of beating concentration and the increase of fiber length, the crack length and breaking resistance will increased. - Elongation.
The elongation is actually the ultimate strain when the paper is pulled, it is also a indicator of the toughness of the paper. In general, the longer and softer the fiber, the higher the elongation after paper formation. With the increase of beating concentration and the increase of fiber length, the elongation must be greatly increased. On the contrary, the dimensional stability is greatly reduced. - Tear Strength and Folding Resistance.
The main factor affecting paper tearing and folding is the average length of fiber. The longer the fibre, the higher the tearing and folding resistance. Therefore, with the increase of beating concentration and the increase of fiber length, the degree of tear and folding resistance will increase significantly. - Opacity.
When paper is formed, the closer the fiber is, the higher the opacity of the paper. With the increase of beating concentration and the increase of fiber length, the close degree of fiber will decrease, so the opacity will decrease.
