What kind of paper is better for drawing paper?
In the production process of bamboo pulp paper, no additives such as fluorescent agent are added, and the color of the paper keeps its original color, which is a bit ugly. In fact, you get used to it after a long time, with good toughness and basically no crumbs. Due to the short growth cycle of raw bamboo, which is not as slow as wood, the price of bamboo pulp paper sold in the market is generally not expensive.
The performance of bamboo pulp is between softwood and hardwood, which is obviously better than straw pulp. It can replace hardwood pulp, reduce the consumption of softwood pulp, and can be used to make all kinds of paper, including all kinds of middle and high-grade paper products. Bamboo pulping technology is mature and reliable, and most of the equipment can adopt domestic products; The pollution control technology is mature, and the "three wastes" can meet the relevant national emission standards. It is worth mentioning that the unique resources in the central and western regions such as Yunnan, Guizhou, Sichuan, Chongqing, Guangxi, Hunan and Jiangxi are very suitable for the growth of bamboo species for pulping and papermaking.
Background introduction of bamboo pulp paper
China is a big country in paper production, consumption and import. In 2002, the output and consumption of paper and paperboard in China ranked second in the world, second only to the United States. With the rapid growth of demand for paper products in China, the supply of wood pulp is far from meeting the demand, which leads to a rapid increase in imports. From 1995 to 200 1, China's paper and paperboard imports increased at an annual rate of 14.5%.
In 20001year, 5.59 million tons of paper and paperboard were imported, accounting for 65.438+07.5% of the total consumption, and 4.9 million tons of commercial wood pulp and 6.42 million tons of waste paper were imported, accounting for 38% of the total pulp consumption. It accounts for the third place in foreign exchange consumption of imported goods. In addition, replacing wood pulp with bamboo pulp is also an urgent need for ecological protection. For the paper industry, wood fiber is much higher than grass fiber in both performance and technology.
