Waterless papermaking new technology

At present, an important issue facing the paper industry is how to increase the output of high-quality paper while reducing the consumption of energy, water and raw materials. According to reports, the National Plant Polymer University of Technology in St. Petersburg, Russia, has developed a process and equipment that can produce high-quality writing and printing paper without polluting the environment. The working principle of this new technology is the aerodynamic molding method. The wood fibers suspended in the high-speed air flow are formed on the fast moving metal mesh. High-speed air flow plays an important role in process equipment.
The new technology has the following advantages: (1) It is conducive to environmental protection; (2) High paper forming speeds up to 2000m/min; (3) Equipment size can be reduced to 50-60%; (4) Pulping energy The consumption is reduced to the original 40-50%; (5) The cost of the paper machine is reduced to 20-25%; (6) The price of paper can be reduced by 15-20%. The special emphasis on this new papermaking technology is that: (1) The new process requires neither water nor chemical additives, and is therefore known as the waterless papermaking process, which does not pollute the environment and is conducive to the environment. Protection (2) Pulp used in conventional paper machines can be used in new paper machines; (3) As the papermaking process using new equipment is relatively simple, the operation will be 30-40% faster than the traditional process.
Because waterless papermaking technology does not use water, paper mills can be built anywhere, for example, in cities. In many countries, the lack of water has limited the development of the paper industry. Now this problem has been solved.
