In the field of pulping and papermaking, Jiangsu Jinwo launched the high-yield pulping technology of EI-TSMP or “Extended Impregnation-Twin Screw Mechanical Pulping” technology, which is developed for wood chips, bamboo chips, cotton fibers, straw raw materials, etc., especially air-dried raw materials to produce chemi-mechanical pulp. It can effectively improve the moisture content of raw materials, achieve homogenization impregnation, reduce grinding power consumption, and reduce the content of fine fibers. According to the different application requirements of pulp, it can greatly improve the physical strength index such as pulp thickness or burst resistance. It is widely used in the production of molded pulp, white cardboard, boxboard paper, household paper, cultural paper, banknote paper and other paper.
