Eliminating the pollution caused by the traditional alkaline and lime pulping and papermaking is one of the purposes for the development of “pollution-free three-dimensional papermakingâ€. After this technical achievement is used by enterprises, the production of cheap, high-quality products is more practical for today's "buyer's market."
This project consists of two standards: Pulp and Paper.
Pulping method is: straw into the straw machine (patent number 952411555), filled with expansion agent, 5 ~ 6 kg of steam steam for one hour and heat for half an hour, with a double screw secondary pulper to complete the first 85% of cooked grass black The liquid is extracted and then rinsed with fresh water in the machine. The entire process of extracting the black liquor and rinsing is completed. The bleached black liquor was decolorized and decontaminated into two layers (about 0.30 yuan per ton of black liquor processing fee). The upper layer is colorless and transparent water, and the COD and BOD are tested as "national standard" grade II. This water is used for recycling. The lower sediment is used as nitrogen and potassium fertilizer in farmland.
If you purchase 400,000 yuan of equipment to build a factory with an annual output of 6,000 tons, the cost per ton of pulp board will be 700 yuan, the sales price will be 950 yuan, and the annual tax profit will be 1.5 million yuan. The investment will be recovered in half a year.
Statistics from the State Economic and Trade Commission show that last year China's annual output of commercial pulp was only 300,000 tons, and the demand for paperboard and paper products was 3.079 million tons (domestic plus imports). It is estimated that the annual output of pulp in China will reach 3 million tons in 2010 to ease market demand. At present, many small and medium-sized paper mills have been shut down due to a large number of environmental pollution. The market for pulp is in short supply and the pulp sales prospects are promising.
Three-dimensional papermaking refers to the use of this kind of paper pulp to make packaging board, decorative board, lightweight interior wall board, honeycomb paperboard and other materials at one time. After Jiangsu issued a ban on white paper, three-dimensional paper is replacing white plastic foam and wood made of industrial products and inexpensive and colorful colored furniture and so on. For example: Turn 950 yuan a ton of pulp into 2200 yuan a ton of paper products, add 1,250 yuan, and remove 700 yuan from other substrates, still adding 550 yuan. This process is characterized by a molding: put the pulp in the machine, after the pressure operation, drying, finishing is the finished product <forming pulp water circulation, no pollution>. This process eliminates the seven or eight production processes that the former paper mills used to pass through to form paper products, saving a substantial amount of water treatment infrastructure investment. In particular, the South-to-North Water Diversion Project is about to start this year. The application of this technology is a small and medium-sized paper mill. The carton plant brings many benefits.
