Green "gold" —— bamboo | Qingya Paper

One ton of bamboo can produce 500-600 kilograms of bamboo pulp. In the case of good management, bamboo bamboo per mu yield is generally about 1.5-2 tons, the production of dry bamboo pieces 1.05-1.4 tons. An acre of bamboo forest can absorb 67 kilograms of carbon dioxide a day and release 49 kilograms of oxygen, enough for 65 people to breathe. It can absorb 4 kilograms of carbon dioxide in a month, equivalent to a fungicide manufacturing machine. One mu of bamboo forest, which can absorb 22 tons to 60 tons of dust a year, is a natural vacuum cleaner. One mu of pine Berlin, a day and night can secrete 2 kilograms of bactericidal element, can kill tuberculosis, typhoid, diphtheria, dysentery and other germs. One mu of broad-leaved forest can evaporate more than 300 tons of water a year. Therefore, areas with many bamboo forests often have good weather.- -Mu of bamboo forest is 20 tons more than an mu of no forest land, which is equal to a groundwater pool. One mu of bamboo forest, in addition to providing bamboo every year, can also provide many industrial raw materials, fuel, feed, oil and so on. If there is no woodland in the world, 70 percent of the earth's fresh water will be empty, and wind speeds in many areas will increase by 60 to 80 percent.

The main chemical components of bamboo include cellulose, hemicellulose and lignin. In the process of pulp and paper making, it is usually necessary to remove lignin and retain cellulose and half fibers.

 Compared to wood, bamboo is more dense, cooking medicine is more difficult to penetrate, and more difficult to remove lignin. In ancient times, tender bamboo is usually used for pulp and paper making. Tbamboo has low density and lignin content is low, which is conducive to cooking liquid medicine

 Permeation and lignin removal.

Modern, with the innovation of pulp and paper making technology, using bamboo to make bleached bamboo pulp, which can use deep delignification technology cooking and multiple non-free chlorine bleaching technology bleaching, less carbohydrate degradation, bleached bamboo pulp has high rate, high strength, and low pollution load in the production process.
 Pulp process
Traditional pulping refers to the production process of using chemical methods, mechanical method or a combination of the two to make the dissociation of plant fiber raw materials into natural or bleached pulp. The usual process is to crush, boil plant fiber raw materials, washing, washing, screening, bleaching, purification, drying.
 Modern new development of a biological pulp method, first with special bacteria (white rot, brown rot, soft rot bacteria) specialized directional decomposition of lignin structure, supplemented by mechanical or chemical methods to remove the remaining cellulose, and then bleaching. In this process, biology has decomposed and opened most of the lignin, the chemical method is only as an auxiliary role, the chemical products used are less than the traditional method, so it can do less discharge or no discharge of waste liquid, is an environmental protection pulping, clean pulping method.

 By 2025, China's bamboo industry output value reached 700 billion yuan, basic modern bamboo industry system, bamboo industry scale, quality, efficiency significantly improved, high quality bamboo products and service supply ability improved significantly, built a batch of internationally competitive innovative leading enterprises, industrial park, industrial cluster, bamboo industry development maintain world leading position. By 2035, the total output value of the national bamboo industry will exceed 1 trillion yuan, the modern bamboo industry system will be improved, the beautiful rural bamboo scenery will be basically completed, the main bamboo products will enter the high end of the global value chain, and China will become the world's bamboo industry power.

 According to relevant data, China's existing bamboo forest area is more than 100 million mu, with an annual output value of nearly 320 billion yuan, more than 15 million employees and an export value of 2.2 billion US dollars.

 The industry people said that the bamboo industry development plan is expected to release in the near future or proposed, China's bamboo industry in 2025 total output value target of 700 billion yuan, by 2035 target of more than 1 trillion yuan. This means that the output value of the bamboo industry will double in 5 years, and the market increment will be nearly 700 billion yuan in 10 years.

 In addition, at the 11th China Bamboo Culture Festival held on October 12, the voice was conveyed: China's ecological civilization construction has entered a strategic period focusing on carbon reduction, promoting the key period of pollution reduction and carbon reduction, synergistic efficiency increase, promoting the comprehensive green transformation of economic and social development, and realizing the improvement of ecological environment quality from quantitative change to qualitative change. The prosperity of bamboo culture and the development of bamboo industry are of great significance to promoting the construction of ecological civilization in China.

Chengdu elegant paper industry focuses on bamboo products, the main products are bamboo pulp, bamboo pulp toilet paper and bamboo pulp packaging paper and other products.
