The adhesive uses inorganic organic chemical raw materials to form a composite multi-polymer, and the gasification type coal produced by the company meets the requirements of industrial gasification production with unique physical and chemical properties. Its biggest feature is that it is suitable for the production of industrial boiler type and gasification type coal for bituminous coal anthracite coke slime, especially high temperature furnace type coal; equipment investment is small.
No need to dry; low production cost, only about 4 yuan per ton of coal; high heat and cold strength, high calorific value, thermal stability of 9, natural coal solidification or drying with residual heat.
The industry believes that the successful development of this technology provides a new way for many chemical fertilizer enterprises in China to use pulverized coal to produce gasified briquette. At present, many fertilizer enterprises have applied this technology to super-high-crosslinking polystyrene adsorption resin jointly developed by Nanjing University Environmental Science Research Institute and Danyang Jinxiang Chemical Factory in Jiangsu Province. Synthesis and its application, recently passed the technical appraisal organized by the Jiangsu Provincial Science and Technology Commission. The resin has a high specific area, a relatively uniform pore distribution and a relatively high mechanical strength, and can be used for the treatment and comprehensive utilization of high-concentration organic chemical wastewater, as well as human blood perfusion antibiotics and Chinese herbal medicine extraction. Especially in the treatment and comprehensive utilization of high-concentration organic chemical wastewater, such as p-nitrophenol 2,3 acid phenylacetic acid o-aniline 2 naphthol tocopheric acid and other organic wastewater using such ultra-high cross-linking adsorption resin fixed bed The industrial treatment of the process not only realizes the effective treatment and discharge of the factory wastewater, but also recovers most of the useful substances from the wastewater for comprehensive utilization.
It is an ideal statistical system for statistically designing and transforming the science of 85-study system design, which can not only meet the comprehensive statistical tasks of the government's comprehensive statistical department. Moreover, it can reflect the input-output benefit concept of statistical work, and avoid repeated crossover and ineffective labor to the utmost extent. Improve the accuracy and practicality of statistical information, and effectively reduce the burden on the grassroots statistical department and the target. How to design a statistical system, choose the appropriate adjustment and organization, make it an important part of the statistical design stage, and become an important measure to ensure the scientific and reasonable statistical work. In terms of the reform of the design of the national statistical system, the author believes that the following principles and ideas should be followed.
Guided by the purpose of national statistics, the design of efficient and practical statistical indicators and grouping is the basis and premise of statistical system design. The purpose of national statistics is to design an important basis for the statistical indicator system and grouping system. Only by closely surrounding the needs of national statistics can we ensure that the design indicators and groupings are efficient and practical.
According to this reform idea, when designing statistical indicators and grouping, we should fully consider the following factors: chemical statistics and information 1230000
