Since the successful industrial development and utilization of bamboo, many new processes, technologies and products of bamboo processing have emerged, which greatly enhance the utilization value of bamboo.
The development of mechanized pulping technology in China has broken through the traditional manual way and is transforming to the industrialization and industrial production mode.
At present, the popular bamboo pulp production technology includes mechanical method, chemical method and chemical.
Mechanical pulping process
Advantages: low pollution, high pulp yield and simple process.
Disadvantages: The high impurity content leads to poor pulp quality, and it is difficult to meet the quality requirements of commercial paper.
Chemical pulping process
Advantages: protect fibers, improve pulp yield, and obtain better pulp quality. It can be used to produce high-grade writing paper and printing paper.
Disadvantages: The pulp yield is 45%~55% (low). The cost of disposing of contamination is greater than that of mechanical pulping.
Chemical mechanical pulping process
The pulp yield is 72%~75%, the papermaking quality is higher than that of the mechanical method, and the pollution treatment cost is between the two, which meets the production needs of general commercial paper.
Nowadays，sized bamboo paper production lines have been industrialized in Guizhou, Sichuan and other places.
