How to increase the thickness of cultural a4 paper in paper making
Cultural a4 paper is writing and printing paper that is mainly used to spread cultural
knowledge in daily life, mainly including: art paper, writing paper, light weight coated paper
and newsprint paper, etc.Increasing the thickness of cultural a4 paper in paper making can
reduce the use of wood pulp, save wood resources, reduce the cutting of forest resources, and
reduce cultural a4 paper production costs.
The method to increase the thickness of cultural a4 paper in paper making
1.Adjust the temperature during paper drying or paper pressing, and lower the pressure during
calendering or overpressure.
2.The thickness of cultural a4 paper in paper making can be increased by
properly improving the freeness of refining pulp and reducing the damage of mechanical action
on lignin in the fiber
3.By adding a certain percentage of mechanical pulp in paper pulp stock preparation line,
mechanical pulp is also known as high yield pulp. Due to its high lignin content, it has
greater advantages in thickness and stiffness
4.The thickness of cultural a4 paper is increased by adding various chemical
additives. The chemical thickening is mainly through the combination of the chemical and the fiber,
so that the gap between the fiber and the fiber is generated to achieve the purpose of cultural
5.The plastic pigment coating on the surface of the paper, the pigment is heated after expansion,
thereby increasing the thickness of the paper.
