Key Technologies Needed to be Solved by China's Pulp and Paper Industry in the Next Decade

　　1,100,000 -300,000 tons of chemical wood (bamboo) pulping production lines;

　　Focus on the development of a low-energy intermittent digester (RDH)-based pulping system. Technical equipment to be solved: Vertical cooking pot, system automatic control, equipment preparation equipment (including peeling, slicing, screening, storage and other equipment)

　　2,100,000-200,000 tons of non-wood fiber pulp production lines:

　　Develop two types of equipment:

　　(1) Horizontal tube continuous digester pulping system: key technology: Design and manufacture of large compression ratio diameter screw feeders; water-saving wet preparation system.

　　(2) Wheat straw rapid thermal displacement cooking system: This technology optimizes the dynamics of the delignification reaction; improves the black liquor evaporation performance, and creates the conditions for the recovery and utilization of low-odor alkali recovery boilers for straw pulp black liquor alkali.

　　3,100,000-200,000 waste paper deinking pulp production lines:

　　Key technologies: deinking equipment with high deinking rate; detection technology and removal equipment for impurities such as viscose and hot melt

　　4,100,000-200,000 tons of high-yield machine pulp production line:

　　Focus on the development of APMP, BCTMP; key technologies: large compression ratio spiral mill; design and manufacture of large-scale high-consistency refiners.

　　5, high-speed cultural paper machine:

　　Key Technologies: White Water Dilutable Controllable Hydraulic Headboxes; Interfolding System; Shoe Wide Gage Pressing System; QCSDCSMCCPLC and Other Control Systems

　　6, high-speed coating machine, soft roller calender, high-speed rewinder;

　　Key technologies: in-machine coater and calender; manufacturing technology for wide-format models; non-contact coating technology and equipment

　　7, advanced emission reduction technologies and technologies

　　"Zero Emissions" (paper and paper, pulp and paper) technology and equipment; white water recycling technology and equipment; countercurrent washing technology and equipment
