顼目和技术 China's fly ash solid waste resources are extremely abundant, and fly ash is used to produce paper products, especially for the market of packaging paper products. Due to the structure of raw materials and environmental protection effects, the cost reduction of fly ash papermaking can reach 50% (according to product requirements. Different from the structure of the raw material, the profit-added value is high. From the preparation of fly ash microfibers, papermaking, to waste recycling or waste degradation, the formation of a green cycle, consistent with the environment, no environmental pollution compared with traditional papermaking technology , Fly ash paper-saving water-saving wood, reduce wood pulp and papermaking wastewater discharge. This technology is a revolution in the structural adjustment of papermaking raw materials and can create significant economic, environmental, and social benefits. This technology is the first new technology at home and abroad. It has 3 invention patents and independent intellectual property rights. The typical demonstration project was implemented in Xiamen Junxing Paper Manufacturing Co., Ltd. in June 2005 to achieve industrial production.
The technical content of industrialization includes the production of ultra-fine fibers from fly ash and the subsequent production of pulp from ultra-fine fibers, and the subsequent production of insulation materials and wall materials. The preparation of fly ash microfibers is to properly formulate the raw materials and fillers of fly ash so that the melting temperature, melt viscosity, and crystallization of the fiber forming furnace are matched with the process parameters of the production equipment to produce the diameter, fiber length, and toughness. Papermaking coarse fibres with strength and slag content up to the technical requirements, then physical processing of coarse fibres (slag removal and geometric homogenization), chemical modification (softening and obtaining appropriate fibre surface properties) using suitable process technology and equipment , De-slag treatment, made into dry pulp, sent to the paper mill and wood fiber slurry, copy paper products.
Fly ash is cheap, mining, crushing and transportation, stone cost is less than 70 yuan/ton, other ore accessories are about 70 yuan/ton, and the conversion rate of fly ash into fiber is 75 90%. Use this project technology to produce one ton of bare super The cost of fine fiber is 600,800 yuan. According to the different uses and grades of paper products, the cost of ultrafine fiber pulp production is 1,000,1400 yuan. Combining fly ash papermaking fiber pulp with 6070% wood pulp, straw pulp or waste paper pulp to produce special paper with inorganic fiber and copying, saving more than 10% of papermaking cost depending on the amount of addition and the difference between paper products. . Fly ash fiber blended paper has unique advantages such as fire resistance, temperature resistance, low hygroscopicity, antisepsis and durability, and anti-mite. As a specialty paper, the product maintains color, lasts for a long time, and has stable surface properties such as light sensitivity, without radiation. harm. The temperature resistance of the plant fiber paper is generally 400450*C, and the temperature of the fly ash fiber blended paper can reach 650700*C, so it has good fire safety performance. These advantages are not possessed by traditional plant fiber paper, so the product of this project has strong product performance competitiveness. According to the prediction of the Ministry of Light Industry, by 2010, the total consumption of paper and paperboard in the Chinese market will be approximately 5,000 million tons, with a per capita of 40 kilograms per year or more.
II. Project Description This project is a cross-disciplinary field and it is an intensive high-tech project. At present, the technology fills the domestic gap and is at the international advanced level. The project's fiber raw material formula, chemical softening modifier formulation, papermaking additive formula, papermaking special technology process and equipment have 58 years of technical protection and unique market technology capabilities, and have the advantage of technology promotion and exclusive possession of technological products. .
Annual output of 20,000 tons of superfine fiber and subsequent pulp manufacturing equipment (or subsequent insulation material manufacturing equipment), including technology transfer, investment costs about 20 million yuan, take the turnkey project.
Product selection: Asphalt package paper, special TTM paper, special SLB paper, etc. Production scale: 20,000 tons per year, 60 tons per day; Power supply project: The total installed capacity of electrical equipment in the whole project is 28, product quality standard: China People's Republic of Industry Standards and Enterprise Standards QB/T3516-1999 II.
