Printing & Writing Paper High Consistency refining

Technology, application and service for high-consistency refining for Printing & Writing paper

Printing & Writing paper production with calcium carbonate added, resulting in low paper breakage, and because the current price difference between chemical mechanical pulp and commercial wood pulp is large, many paper mills hope to increase the amount of chemical mechanical pulp to reduce raw material costs. However, in the existing low-consistency refining of hardwood pulp or other short fibers, the strength of short fibers is limited, so that the strength performance of the paper is not high enough. We use high-consistency to process hardwood pulp or other short-fiber chemical pulp to increase the strength, reduce the long-fiber ratio or increase the chemical-mechanical pulp ratio.

1. Process Technology

• The advantages of high-consistency refining applied to Printing & Writing paper:
• 
  
• It can effectively improve the tensile strength, tear strength, folding endurance and other strength properties of paper, and reduce the amount of long fibers usage;
• 
  
• The fiber retention rate is high, the white water concentration under the mesh is low, the water filtration is good, and the production cost is effectively reduced;
• 
  
• Improve the bonding performance of fine fibers and long fibers, improve the phenomenon of dust and powder loss, and increase ash content;
• 
  
• It can soften fibers, increase the bulk of the paper, and improve the printability of the paper;
• 
  
• Under the same strength index, the beating degree of can be reduced and power consumption can be saved;

2.  Solution
