China Drying Network News The key technology development and industrialization demonstration project of polybutene-1 synthesis under the auspices of Professor He Aihua from the School of Polymer Science and Engineering of Qingdao University of Science and Technology was recently approved as a national science and technology support project for the “Twelfth Five-Year Planâ€. It is reported that this subject is one of the sub-topics for the development of key technologies for the preparation of high-performance polyolefin-specific resins for the National Science and Technology Support Program Key Project. According to reports, Qingdao University of Science and Technology will cooperate with Shandong Dongfang Hongye Chemical Co., Ltd., and plans to build the first domestic polybutene production demonstration line in Shouguang City in 2014 through three years of research and development to form a 10,000-ton production capacity. New polybutene products for building pipes and floor heating pipes. The raw material of polybutene is the butene-1 component in the liquefied gas. Since there is no polybutene product in China before, this component is mainly burned as liquefied gas. According to rough statistics, in 2010 China's butene resources were about 2.6 million tons, of which only a small amount (less than 5%) was used for the synthesis of linear low density polyethylene (LLDPE), and most of the remaining butene was used as liquefied gas. According to Prof. He Aihua, the person in charge of the project, Polybutene is a very special polyolefin material with excellent heat-resistant creep resistance and stress crack resistance, and its heat-resistant creep resistance is significantly better than that of general-purpose polypropylene. And polyethylene, can be used at 95 °C for a long time, mainly used for industrial and civilian hot and cold water pipes and accessories, is the best floor heating pipe material. At present, China's polybutene is completely dependent on imports. The price of high-grade polybutene for floor heating pipes is 30,000 to 40,000 yuan/ton.

Our isostatic graphite and Molded Graphite were tested at the National Electrical Carbon Products Quality Supervision and Inspection Center. The main physical and chemical performance index as follows: the compressive strength--125 mpa, shore hardness -- 65 degrees, resistivity --12 mu Ω m. At the same time, the 10μm,8μm,6μm,4μm products have already began Large-scale production,.and unanimously acknowledged by customers. The 2μm,1μm graphite products are under trial. Our company high quality of isostatic pressing special graphite yield above 90%, far ahead of industry the yield of 70%, the first in the country.
EDM graphite, also known as graphite block for EDM, is a new type of material, which is now more and more widely used in the precision mold processing industry. At present, in mold processing plants in developed European countries, more than 90% of mold processing electrode materials are graphite. Copper, the once dominant electrode material, has almost lost its advantages compared with graphite electrodes.
