According to the definition of the "Intelligent Manufacturing Development Plan (2016-2020)" issued by the Ministry of Industry and Information Technology and the Ministry of Finance, Intelligent Manufacturing (IM) is based on the deep integration of a new generation of information and communication technology and advanced manufacturing technology, including basic commonalities , Key technologies, and industry applications. In recent years, the manufacturing industry has regained the focus of developed countries, such as the German Industry 4.0 strategy and the American advanced manufacturing strategy. The remanufacturing of developed countries has promoted the accelerated arrival of the era of intelligent manufacturing. "Made in China 2025", as the action plan of the manufacturing power strategy, clearly takes intelligent manufacturing as the main direction, and proposes: speed up the intelligent transformation of production equipment in machinery, aviation, shipbuilding, automobile, light industry, textile, food, electronics and other industries to improve precision Manufacturing and agile manufacturing capabilities; coordinate the layout and promote the R&D and industrialization of products such as smart transportation tools, smart construction machinery, service robots, smart home appliances, smart lighting appliances, and wearable devices; develop personalized customization, crowdsourcing design based on the Internet, New manufacturing modes such as cloud manufacturing promote the formation of R&D, manufacturing and industrial organization methods based on the dynamic perception of consumer demand. The clear content of this action plan includes CNC machine tools, industrial robots, additive manufacturing equipment, non-standard automation equipment, smart factories, etc., and points out new production methods that accelerate the application of a new generation of information technology and advanced manufacturing technology. Intelligent manufacturing is the empowering result of a new generation of information technology and the entire life cycle of manufacturing. Through the empowerment of industrial Internet, industrial big data, artificial intelligence and other technologies, the manufacturing industry can be intelligently produced. At present, my country's intelligent manufacturing has entered a stage of deepening application and comprehensive promotion, and the level of intelligent manufacturing has been significantly improved. Among industry applications, the automotive manufacturing industry has the highest level of intelligent manufacturing; the intelligent manufacturing industry is showing a trend of "strong in the east and weak in the west". Although my country is a big manufacturing country, the regional technology development is uneven, the level of informatization development is uneven, and the degree of standardization is low. With the rise of labor costs, the transfer of low-end manufacturing, the development of science a...

Recently, under the unified deployment of the China Environmental Protection Industry Association, the Anhui Provincial Environmental Protection Industry Development Promotion Association conducted a quarterly analysis and investigation on the operation of the environmental protection industry in Anhui Province, and more than 50 key enterprises participated in the investigation. This report is an analysis of the operation situation of the environmental protection industry in Anhui Province in the second quarter and the first half of 2021. The data collection is mainly based on the second quarter and supplemented by the first quarter. It mainly focuses on the basic situation, business operations, industry operation prospects, and the status and faces of the Anhui environmental protection industry. Elaborate on the situation, policy recommendations and other aspects. The report pointed out that there is a certain gap between Anhui's industry in terms of size and R&D capabilities and Shanghai, Zhejiang and Jiangsu in the integration of the Yangtze River Delta, but the distance is the development potential and space. The report emphasized that the scenery should be long-term. It is expected that the Anhui industry will boost their confidence to catch up, grasp the rare strategic opportunity period that the integration of the Yangtze River Delta will bring to the Anhui industry, and continue the new legend of the industry in Huizhou. In recent years, under the influence of the national ecological civilization construction and industrial green development trend, the development needs of the environmental protection industry in Anhui Province have been increasing. In 2013, Anhui Province issued the "Development Plan for Energy Conservation and Environmental Protection Industry in Anhui Province", which clearly made the environmental protection industry one of the key industries in the province for cultivation and development. Since then, Anhui Province has successively issued "Implementation Opinions on the Implementation of the "Five Hundred" Special Actions for Energy-saving and Environmental Protection Industries in the Industrial Field", "The 13th Five-Year Plan for Industrial Green Development in Anhui Province", and "The 13th Five-Year Plan for Strategic Emerging Industries in Anhui Province" "Development Plan" and other policies, focusing on the development and promotion of advanced environmental protection technology and equipment in the fields of air treatment, waste incineration, waste recycling, pollution source monitoring, etc., and vigorously develop source reduction, pollution control, and recycling technologies. As the first year of the "14th Five-Year Plan", economic strategies and development plans at all levels have attracted more attention. In the local two sessions held in the first half of the year, the work reports of many governments released a signal to continue to increase green development and expand and strengthen the envi...

Polyimide fiber is spun from polyamic acid or polyimide solution. Due to the high density of aromatic rings in its molecular structure and the phthalimide structure in macromolecules, polyimide fiber has Excellent heat resistance, radiation resistance, high strength and high modulus, flame retardancy and other properties, has become one of the fast-developing high-performance fibers. Polyimide fiber is mainly used for high temperature dust removal. Polyimide fiber dust bag is mainly used in asphalt mixing, cement kiln and garbage incineration industries. With the development of its manufacturing process, polyimide fibers have gradually been widely used in aerospace, new building materials, environmental industries, fireproof materials, etc. Usually we will see P84 fiber, PI fiber, Yilun, imported P84, domestic P84 and so on. Imported P84 is a representative polyimide fiber product from abroad, while domestically produced P84 or PI fiber is a polyimide fiber produced in my country, also known as Yilun. So what is the difference between these two fibers? (1) Microscopic cross section: P84 fiber, the most well-known is its trilobal cross section, so it has a relatively large specific surface area and a good filtering effect. The PI fiber section is mostly circular. (2) Color: P84 fiber is golden yellow, and the fiber is fluffy. PI fiber is brownish red, which is darker than P84. (3) Performance: Both P84 fiber and PI fiber have excellent temperature resistance, up to 260°C. In order to improve spinnability, diisocyanate is added to the raw material of P84 fiber, which causes the fiber's heat resistance stability to be lower than that of PI fiber, which has a longer replacement cycle. (4) Price: The first monomer of P84 uses ketone anhydride, the market price is about 400,000-500,000 yuan/ton, while the PI fiber uses homoanhydride, the market price is only 70,000 yuan/ton, so P84 is better than PI The price is much higher. Considering comprehensively, the three-lobed cross section of P84 brings higher filtration efficiency. PI has advantages in temperature stability and price. We can consider the use of different fibers according to different working conditions. At the same time, if PI fiber wants to replace P84 fiber, there are still some problems. Challenges, process complexity, no reference technology, low market recognition, etc. The commonly used fibers of Yuanchen Technology include polyester, acrylic, PPS, aramid, PTFE, glass fiber, etc. Its high-efficiency dust removal filter material uses high-performance fiber and high-strength base cloth as the main raw materials, and the product has a sophisticated production process and is mainly used in thermal power generation. , Building materials, steel, waste incineration, chemicals, glass and other industries can comprehensively improve my country’s air pollution prevention and control capabilities, achieve ultra-clean emissions, and meet major national strategic needs in the field of env...
