Tissue Paper High Consistency Refining
Technology, application and service for
high-consistency refining of hardwood pulp on Tissue paper:
For treating hardwood pulp, the high consistency refining system can increase tensile and bursting strength so to lessen use of softwood fiber.
Tissue paper using hardwood pulp and softwood pulp as raw materials has the problem of a large proportion of long fibers (usually ranging from 20-35%), and the average price difference between long and short fibers is $300 USD, which is cost concerns on paper mills. The main reason is that low-consistency refining is applied to treat hardwood pulp, light refining is generally used. Short fibers do not provide the strength required by tissue paper, which are mainly provided by long fibers.
The reason why heavy refining cannot be used due to low-consistency severely cuts fibers. Although the tensile strength can be improved, it cannot guarantee the strength properties related to paper making and post-processing, such as breaking resistance and tearing, while also reduce bulk.
The high-consistency refining system provided by Genda can solve this problem. High-consistency refining process hardwood pulp will not cause fiber cutting no matter how high the beating degree is. At the same time, the fiber kink and curl produced by high-consistency refining process can also maintain a good bulk. Hardwood pulp can give full play to the strength properties of short fiber raw materials through HC refining process. While maintaining various strength indicators and bulk, the long fiber ratio is reduced by 10-15%, which greatly optimizes cost reduction. At the same time, high-consistency refining can greatly improve the softness and surface smoothness of the finished paper. Genda have cooperated with many customers and have completed the construction and renovation of more than 20 wood pulp tissue production lines. Our supply covers various needs of customers: innovative technology, reliability and operability, and advanced automation solutions and turnkey engineering services to ensure your paper performance improvement and cost reduction while maintaining smooth operation.
