What is the most important factor in copying out good paper
"Paper is beaten and beaten", "A clever woman can't cook without rice", these principles all understand, in today's paper-making raw materials are scarce, how to better use raw materials in enterprises is worth thinking, do you really understand the following?
In the papermaking process, it is necessary to carry out the ratio of different pulps, the most important thing is to consider the nature of the paper being copied, and the second is to consider the production cost.
The proportion of pulp depends on factors such as raw material characteristics, pulping method, paper machine performance, paper variety and quality requirements. After combining various factors to determine the proportioning conditions, it is necessary to strictly implement the process conditions, otherwise it will cause production disturbances and increase the production cost of papermaking.
In order to ensure the normal production of the paper machine, and pay attention to the economic benefits of the product, the paper is often made from several sizes of paper. Chemical grass pulp has short fibers, thick cell walls, many miscellaneous cells, and high content of semi-fibers, which makes it difficult to make paper machines and affect the quality of paper.
Therefore, according to the quality requirements of different paper varieties, some long-fiber raw materials with better performance must be used to make up for the defects of grass pulp, such as higher-priced chemical cotton, wood, hemp pulp, etc., in order to benefit the paper machine. Copy-made, and meet product quality requirements.
The proportion of long and short fibers in the pulp composition is an important factor affecting the quality of papermaking and papermaking. Appropriate ratio of long and short fibers can increase the binding force between fibers, improve the uniformity of paper sheets, and improve the strength of paper. On the other hand, it can reduce production costs and increase economic benefits. In the proportioning process, if the proportion of the long fiber is small, it will affect the binding force of the paper, reduce the strength of the wet paper, and cause the sticking roller to break; but if the proportion is too large, the economy is not cost-effective.
Of course, it is a relatively complicated job to really do a good job of slurry matching. There is still a lot of work that needs to be constantly explored and summarized in production practice.
