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.
A ductile power Manhole Cover is a type of manhole cover that is made from ductile iron, which is a type of cast iron that has been treated with magnesium to enhance its strength and ductility.
Ductile power manhole covers are designed to withstand heavy loads and provide a durable and long-lasting solution for covering underground utility access points. They have a high load-bearing capacity, making them suitable for areas with heavy traffic, such as roads, highways, and industrial sites.
These manhole covers are typically round or square in shape and feature a solid design with reinforced edges to prevent cracking and breakage. They are often equipped with lifting handles or lifting points for easy access and removal during maintenance or inspection activities.
Ductile power manhole covers are known for their resistance to corrosion, making them suitable for use in various environments, including urban, coastal, and industrial areas. They are also designed to be slip-resistant, providing a safe walking surface for pedestrians and vehicles.
Additionally, these manhole covers may have features such as locking mechanisms or anti-theft devices to prevent unauthorized access or theft. They can also be customized with logos, markings, or color-coding to indicate the type of utility or service they cover.
Overall, ductile power manhole covers offer a reliable and efficient solution for securing underground utility infrastructure while ensuring safety and ease of access for maintenance and inspection purposes.
