Carry forward the ancient non wood fiber paper technology, green low-carbon office and new life

the historical development of the application of ancient non wood fiber paper technology in China

papermaking originated in China and is the first of the four major inventions. Ancient Chinese papermaking has a long history in the use of non wood fiber raw materials

according to the "biography of Cai Lun in the later Han Dynasty", when the specimen with large elongation is not suitable for papermaking, the raw materials used are mainly hemp, rags, fish and bark

from the fifth year of Xiankang of emperor Cheng of the Eastern Jin Dynasty to the fifth year of Long'an of emperor an, that is, in AD, grass was used to make paper

according to the "brief history of Chinese papermaking technology" (published in 1994), foil paper is bamboo papermaking, which shows that bamboo paper existed in China in the Jin Dynasty

at the end of the Ming Dynasty, from 1600 to 1644 A.D., China's paper mills began to use waste paper to make paper

the use of bagasse for papermaking began in China in the 29th year of the reign of Emperor Guangxu of the Qing Dynasty, that is, in 1904. At the same time, China also began deinking waste paper

non wood fibers also played a decisive role in the development of paper industry in New China. In the 1950s and 1960s, Shandong used 100% wheat straw pulp to produce and export glossy paper, and in the 1960s and 1970s, Jiangsu used 100% wheat straw pulp to produce and export writing paper and offset paper. Since the 1990s, bamboo pulp, sugarcane pulp, wheat straw pulp, straw pulp and wood pulp have been used to produce all kinds of high-end cultural paper, office paper and household series paper. At the same time, non plant fibers have become important production raw materials for special paper, such as the application of organic synthetic fibers and fly ash fibers in special paper, and the introduction of stone paper during the two sessions this year

non wood fiber paper products have little significance in creating a green and low-carbon economic life. 1. The journey of the general electro-hydraulic servo experimental machine

bamboo pulp fiber

bamboo has developed roots and is an ideal plant to prevent soil desertification and floods. Each hectare of bamboo forest can absorb 12 tons of carbon dioxide every year, and it can release 35% more oxygen than other plants

sugarcane pulp fiber

each ton of bagasse can be replaced 25 cubic meters of wood, and carbohydrate is used in the process of sugarcane pulp papermaking and fermentation. After production and processing, it is processed into fertilizer, which makes these nutrients return to the land, keeps the land healthy and nutrient balanced forever, maintains the ecological balance, and realizes the real circular economy

rice and wheat straw fiber

in the past, the treatment of rice and wheat straw was mostly incineration, which emitted a large amount of carbon dioxide. Therefore, rice and wheat straw pulping and papermaking is not only a problem of renewable resources utilization, but also one of the relief channels for the treatment of important sources of carbon emissions in China

recycled fiber of waste paper

a ton of waste paper can produce 850 kg of recycled paper with good quality, save 3 cubic meters of wood, save 100 cubic meters of water, save 300 kg of chemical raw materials, save 12000 tons of coal, and save 600 degrees of electricity. In addition, recycled paper can reduce wastewater discharge by 50% in the manufacturing process

prospects for the application of non wood fiber paper products in China

the paper industry development policy points out that: make full use of domestic and foreign resources, increase the proportion of wood, expand the recycling of waste paper, use non wood pulp reasonably, and gradually form a papermaking raw material structure dominated by wood fiber and waste paper, supplemented by non wood fiber. Under the current national conditions of China, where the integration of domestic forestry and paper is far from enough and the quantity and price of imported waste paper are rising, we must strengthen the rational use of non wood fibers and continue to accelerate the development of China's paper industry

China is a large agricultural country with rich non wood fiber resources. There are more than 120 million hectares of arable land in China, with an annual output of more than 500 million tons of grain and more than 600 million tons of agricultural orange stalks. The annual output of non wood fiber is more than 700 million tons, including reed, bamboo, Gracilaria, Achnatherum splendens and yellow bamboo grass, which can be used as renewable resources for papermaking

the key to papermaking with non wood fibers is the treatment of environmental pollution. It is gratifying that in recent years, with the alkali recovery of wheat straw pulp, black liquor extraction, circular cooking technology, pulping wastewater irrigation, solidification combustion, black liquor recycling and other wastewater comprehensive treatment technology difficulties have been overcome and widely used, the environmental pollution of non wood fiber pulping and papermaking has been significantly improved, creating a good prospect for the use of non wood fiber resources

exploration and Prospect of Anxing paper in the application of non wood fiber paper

Anxing paper, founded in Hong Kong in 1973, is the first generation of multi-functional information recording paper supplier in Asia. It has successively invested and opened various types of paper production and processing bases and more than 30 marketing institutions in Guangdong, Shanghai, Jiangsu, Tianjin, Beijing, Guangxi, Shandong, Fujian and other provinces and cities. The self built production and processing base covers an area of 80000 square meters. It has more than 50 sets of industry-leading equipment, such as multi-color high-speed commercial wheel transfer brush machine, double rotary automatic paper cutter, multi-functional page dispenser, and specializes in providing copy paper, computer paper, fax paper, cash register paper The one-stop service of commercial paper products and commercial printed matter such as booklets, cartons, form printing, bill printing, anti-counterfeiting printing, with an annual output of more than 120000 tons, is one of the key points for the operation of hydraulic universal testing machines for China's three major commercial papers

according to country 12 According to the requirements of the fifth plan, under the guidance of the scientific development concept of China's paper industry, Anxing paper is committed to the conversion, application and promotion of the above non wood fiber resources and waste paper renewable resource products. Since 2000, the company has made in-depth strategic cooperation with large domestic paper mills with resource advantages, technical strength and meeting the national environmental protection requirements in the upstream, and actively developed non wood fiber resources such as bamboo pulp, sugarcane pulp and reed pulp, as well as waste paper recycling resources. The company uses the most advanced chlorine free bleaching pulping process in the world to produce bamboo pulp electrostatic copy paper, which meets the national environmental protection standards; In 2005, it invested in the sugarcane pulp recycling project with Nanning Sugar Industry, and the products passed the SGS test; Recycled electrostatic copy paper is produced by waste paper deinking and pulping process. At present, the above resources have been widely used in self owned copy paper, computer paper and other business paper products, with an annual manufacturing and sales of more than 60000 tons

in the future development plan, Anxing paper industry will continue to take making good use of resources, beautifying the environment, providing fast, appropriate and fine product services for society and customers as its mission, continue the technology transformation and application of non wood fiber paper products and the integration of industrial resources, build the enterprise into an integrated supply service provider of China's green low-carbon paper products, promote non wood fiber raw material products to the world, and revitalize China's national paper industry, Create a new green and low-carbon office life
