The first sample of the slurry preliminary testing, the performance indicators meet the design requirements, produced by the high-strength corrugated paper up to the national A-level standard.
The project is supporting the development of Xi'an Paper Machinery Factory project, first in the country, especially cotton stalk APMP pulping process, there has been positive in the areas of the world.
According to Li Jimin, the technical center of the plant, APMP pulping technology is a friendly and environmentally friendly project. It has the reputation of “clean pulping†and is in line with the development of circular economy in China's pulp and paper industry.
The process has the characteristics of “three highs and four lowsâ€, namely high yield, high whiteness, high strength and low pollution, low loss, low energy consumption and low water consumption.
The traditional pulping process consumes about 100 tons of water per ton of pulp and pollutes the environment. The water consumption of the process is controlled within 20 tons, and then treated with sewage, the COD of the wastewater outlet can be reduced to 80mg/L, the BOD is reduced to 20mg/L, and the SS is reduced to 10mg/L, which is lower than the national sewage discharge standard. 90%% of the wastewater can be recycled for production, achieving zero emissions of wastewater.
The new APMP pulping process is not only clean and environmentally friendly, but also enables paper companies to achieve significant economic benefits.
In terms of fixed investment, foreign similar equipment is as short as 70,000 yuan and hundreds of millions. The APMP equipment (including environmentally friendly treatment systems) is less than one-tenth the price of imported equipment.
In addition to wood, cotton stalks, kenaf, bamboo, salix, rice straw, twigs, reeds, bagasse, etc. are all suitable materials for APMP. The high-strength corrugated base paper produced by the new APMP process has low cost and high quality up to the domestic A-class standard.
It is understood that the new APMP pulping process developed by Xi'an Paper Machinery Factory has attracted great attention from papermaking enterprises at home and abroad. So far, it has received more than 50 copies from Canada, Vietnam, Indonesia and other countries.
Last month, the Xi'an Paper Machinery Factory, a senior enterprise in the domestic paper machinery industry, invested nearly 10 million yuan to renovate the annual output of 20,000 tons of cotton stalk APMP pulp production line in Shaanxi Luhe Paper.
