[0002] At present, the import of waste paper from the United States has been stopped, the recycling cycle of domestic waste paper has been shortened, the quality of waste paper has deteriorated significantly, and the folding resistance index of finished paper has become increasingly difficult to achieve, resulting in frequent quality problems such as cracking in cartons and paperboards produced by downstream customers. It is difficult to improve the folding resistance of finished paper by traditionally adjusting the pulp-to-wire speed ratio, lip plate opening, and spraying angle of the paper machine. The folding resistance index of finished paper can be effectively improved by adding high-quality raw materials such as virgin wood pulp and imported recycled pulp, but the price of virgin wood pulp and imported recycled pulp is often 2-3 times that of domestic waste, and the production cost of base paper has risen sharply.
