Pollution-free PST technology won the national patent

By using the functions of heat, mechanics, and catalysts, the straw pulp obtained from the separation of fibers from plants such as rice straw and wheat straw and other cells is subjected to the PST method of papermaking and board making, and has now obtained a national patent. This method is not chemical pulping. Factory production has been successful and has been applied in many applications. The application of this technology solves the problem that a large number of crop stalks cannot be fully utilized, so that the environmental problems of black water pollution caused by traditional chemical papermaking can be solved, and at the same time, the tension of primary paper paper sources can be reduced. Using this method to carry out technological transformation of small and medium-sized paper mills can reduce production costs and provide an effective method for improving production and quality.
