Among the 325 award-winning projects, there were 36 technical invention awards and 289 science and technology progress awards; a total of 10 projects won the first prize for technological inventions, and a total of 38 projects won the first prize for scientific and technological progress. In addition, nine comrades of this year were awarded the Outstanding Contribution Award for Youth Science and Technology of the China Petroleum and Chemical Industry Federation. 132 comrades were awarded the title of National Outstanding Scientific and Technological Workers, and 23 enterprises were identified as demonstrations of technological innovation in the Chinese chemical industry. enterprise.
In the first prize for scientific and technological progress, the membrane pole-pole bipolar ion membrane electrolyzer developed by Bluestar (Beijing) Chemical Machinery Co., Ltd. has reached the advanced level in the world and has occupied half of the domestic market. The polymer precision extrusion molding technology and equipment independently developed by Beijing University of Chemical Technology has been widely used in the production of precision medical catheters, automotive hydraulic hoses, multi-storey automotive fuel hoses, multi-layer cross-linked polyethylene pipes, and other precision products. The precision of similar advanced equipment. In addition, 89 projects won the second prize for scientific and technological progress, and 162 projects won the third prize.
In this year's project that won the first prize for technical invention, the double-trapezoidal sand control screen tube developed by China University of Petroleum (East China) and its micro-plasma processing technology have solved the worldwide exploitation of loose sandstone oil and gas reservoirs. The problem is that 37 automated processing lines have been built and the direct economic benefits exceed RMB 500 million. The key engineering technologies developed by East China University of Science and Technology and Shanghai Huiyuan Industrial Co., Ltd., which have independent intellectual property rights for carbon dioxide utilization and green use, have broken through the traditional ways in which countries such as Europe and America rely solely on capturing and sequestering carbon dioxide to achieve CO2 emission reduction. Carbon dioxide is eventually synthesized as a green chemical. The application practice has proved that about 280,000 tons of carbon dioxide can be recycled and used annually, energy saving can reach 884,000 tons of standard coal, and wastewater discharge can be reduced by more than 10 million tons. Another 15 projects won the second prize for technological inventions and 11 projects won the third prize.
According to Hu Qianlin, deputy secretary-general of the Petrochemical Federation, many of the 325 results won this year have won national patent authorizations, indicating that the petroleum and chemical industries have made major breakthroughs in original innovation and independent innovation. At the same time, a considerable number of projects are led by companies, which fully reflects the positive progress made in the construction of industry-based technological innovation systems based on independent innovation.
1.cylindrical milling cutter
Used for processing flat surfaces on horizontal milling machines. Cutter teeth are distributed on the circumference of the milling cutter, and are divided into straight teeth and spiral teeth according to tooth shape. According to the number of teeth and coarse teeth and two kinds of fine teeth. The helical tooth rough tooth milling cutter has fewer teeth, high tooth strength and large chip space, which is suitable for rough machining. Fine-tooth milling cutters are suitable for finishing.
2. face milling cutter
Also known as disc milling cutter, used for vertical milling machine, end milling machine or gantry milling machine processing plane, end face and circumference have cutter teeth, also have coarse teeth and fine teeth. The structure has three kinds: integral type, insert type and transferable type.
3. End milling cutter
Used for processing grooves and step surface, knife teeth in the circumference and end face, can not work along the axial feed. When the end mill has end teeth through the center, axial feed can be provided.
4. Three-side edge milling cutter
Used for processing all kinds of grooves and steps, its two sides and circumference are provided with cutter teeth.
5. Angle milling cutter
For milling grooves at a certain Angle, there are two kinds of single Angle and double Angle milling cutters.
6.Saw Blade milling cutter
Used for machining deep grooves and cutting off workpieces, there are more cutter teeth on the circumference. In order to reduce the friction during milling, there are 15 '~1° auxiliary Angle on both sides of the cutter teeth. In addition, there are keyway milling cutters, dovetail slot milling cutters, T - shaped slot milling cutters and various forms of milling cutters.
