China Drying Network On January 18, the CPC Central Committee and the State Council held a grand National Science and Technology Award Conference in the Great Hall of the People in Beijing. At the meeting, the results of the 2012 National Science and Technology Awards were announced. There are 263 general-purpose projects on the list, of which 53 are chemical and chemical projects, accounting for about 20% of the total number of awards. The Sinopec gas field safe and efficient mining project won a special award for scientific and technological progress. In the 2012 national science and technology award winning project, a total of 9 chemical and chemical projects won the National Natural Science Award, 17 projects won the National Technology Invention Award, and 27 projects won the National Science and Technology Progress Award. The total number of awards is basically the same as in previous years. The results of the awards show that the original innovation, independent innovation and integrated innovation capabilities of the petroleum and chemical industries in China are still at a steady improvement stage. In this year's award-winning projects, an important feature is that the total number of National Natural Science Awards and National Technological Invention Awards reached 26. These two awards are the most direct expression of original innovation capabilities. This to a certain extent shows that the original innovation capabilities of the petroleum and chemical industries have been continuously improved. Among them, the second prize for technological inventions, micro-structured chemical mass transfer equipment and its industrial applications, invented a series of micro-structured elements and their amplification and integration methods, and created a variety of microstructured mass transfer equipment, successfully applied to the preparation of nano-calcium carbonates. In the large-scale industrial production such as extraction and purification of wet-process phosphoric acid and caprolactam acid group extraction, a major breakthrough has been achieved in the miniaturization of chemical equipment from concept to industrial practice, such as the micro-meshing device with a capacity of 50,000 tons/year P2O5. And the manufacturing cost is only 1/2000 and 1/50 of the imported equipment. The project was granted 11 invention patents and 68 SCI papers. The promotion and application of micro-structured equipment will help the chemical industry to advance toward high efficiency, greenness and safety, and produce significant economic and social benefits. According to incomplete statistics, the project has accumulated economic benefits of 933 million yuan in the past three years. The second-class HFCs gas phase fluorination catalyst preparation and industrial application technology project that also won the second prize for technological invention has been granted 23 national invention patents, and has won the China Patent Excellence Award, the Special Prize for Invention and Entrepreneurship, etc., and formed the system intellectual property rights. Gas-phase catalytic fluorination technology. Another feature of this year's award-winning project is the extensive participation of companies. Among the 27 projects that won the Science and Technology Progress Award, the participation rate of enterprises reached more than 90%. This shows that the status of enterprises as the main body of innovation is constantly being strengthened. For example, the safety, high-efficiency development technology and industrial application projects of ultra-deep, high-sulfur gas fields jointly completed by Sinopec and many other companies, universities, and research institutes have won the National Science and Technology Progress Grand Prize. The key technology for multi-stage fracturing and production stimulation of horizontal wells and completion of large-scale industrial application projects completed by CNPC and other companies has won the first prize for scientific and technological progress. In addition, the technological innovation platform for controlled-release fertilizer technology that won the second prize for national science and technology progress was independently undertaken by Shandong Jinzhengda Ecological Engineering Co., Ltd. The 2012 National Top Science and Technology Award was awarded to two academicians Zheng Zhemin and Wang Xiaojian. Five foreign experts, including US chemist Richard Jair, won the People's Republic of China International Scientific and Technological Cooperation Award this year. This year's National Natural Science Prize was once again vacant. Sss Spunbond Nonwoven Production Line
SSS: Spunbond non-woven fabric + spunbond non-woven fabric + spunbond non-woven fabric = 3 layers of fiber web hot rolled; S non-woven fabrics, SS non-woven fabrics, SSS non-woven fabrics can be produced, according to non-woven fabrics Cloth performance can be used for: surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, wipes, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable sanitary cloths Cloths, tablecloths, bed sheets, bedspreads; clothing linings, fusible linings, wadding, shaped cotton, various synthetic leather base fabrics, industrial filter materials, insulating materials, cement packaging bags, geotextiles, covered cloths, crop protection cloths, seedling cloths , Irrigation cloth, thermal insulation curtain, other space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc. Mainly used in disposable hygiene products industry, medical health industry, beauty care and other industries.In terms of environmental protection, the raw material of most of the non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are far apart. The chemical molecular structure of polyethylene is very stable and extremely difficult to degrade, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which can be effectively degraded , And enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, the non-woven shopping bag can be reused more than 10 times, and the pollution degree to the environment after being discarded is only 10% of that of the plastic bag.
