The industry is looking forward to the long-term energy-saving and new energy vehicle industry development planning boots have finally fallen. Yesterday, Premier Wen Jiabao of the State Council presided over the State Council executive meeting to discuss and adopt the "Energy Conservation and New Energy Vehicle Industry Development Plan (2012-2020)" (hereinafter referred to as "Planning"). According to the "Planning", China will strive to achieve a total production and sales volume of 500,000 pure electric vehicles and plug-in hybrid vehicles by 2015, and more than 5 million by 2020. Compared with the versions circulating in the industry earlier, non-plug-in hybrid vehicles also have a place. The technical route that the industry has been discussing has also been clear yesterday. The "Planning" pointed out that it is necessary to use pure electric drive as the main strategic orientation for the transformation of the automobile industry. At present, we will focus on promoting the industrialization of pure electric vehicles and plug-in hybrid vehicles, popularizing non-plug-in hybrid vehicles and energy-saving internal combustion engines, and upgrading China. The overall technical level of the automotive industry. Industry: Sales target has been digested by the market According to the Plan, the average fuel consumption of passenger cars produced in 2015 fell to 6.9 liters per 100 kilometers, and fell to 5.0 liters by 2020. Honda Technology Industrial Co., Ltd. and Executive Director of China, Cang Shicheng, pointed out that China's new fuel consumption regulations will become the most stringent regulations in the world by 2015. To meet the requirements of this new regulation, car companies need to increase their investment in new energy technologies. Yesterday, a car enterprise authority who had read the draft "Planning" told this reporter that the sales target has been digested by the market, but added to the development route to promote the popularization of non-plug-in hybrid vehicles and energy-saving internal combustion engines. The expression shows that the competent authorities have adopted a more pragmatic attitude. It is reported that the production of hybrid vehicles does not require major changes to the infrastructure and the cost is relatively low. The reporter learned that due to infrastructure and expensive prices, the development of the new energy automobile industry has been facing embarrassment. In order to implement the "Planning", yesterday's meeting put forward four requirements, including the construction of slow charging piles and public fast charging and replacement facilities according to local conditions, and the implementation of policies to encourage the purchase and use of energy-saving vehicles. Forecast: Energy-consuming power battery module 15 billion watt-hours / year 500,000 new energy vehicles mean a lot of new materials. According to the Ministry of Industry and Information Technology, this is equivalent to the need for energy-type power battery modules of 15 billion watt-hours/year, power type of 300 million watt-hours/year, battery separators of 100 million square meters/year, lithium hexafluorophosphate electrolyte salt of 1,000 tons/year, and 10,000 tons of cathode materials. /year, carbon-based anode material 4000 tons / year. Extract from the Plan It is necessary to use pure electric drive as the main strategic orientation for the transformation of the automobile industry. At present, we will focus on promoting the industrialization of pure electric vehicles and plug-in hybrid vehicles, and popularizing non-plug-in hybrid vehicles and energy-saving internal combustion engines. In 2015, the cumulative production and sales of pure electric vehicles and plug-in hybrid vehicles will reach 500,000 units, and by 2020, they will exceed 5 million units. It is necessary to significantly improve the fuel economy level of automobiles and the safety, reliability and lightness of power battery systems. Implement a policy to encourage the purchase and use of energy-efficient vehicles, and carry out private subsidies for the purchase of new energy vehicles. We will build slow charging piles and public fast charging and replacing facilities according to local conditions, formulate management measures for recycling and utilization of power batteries, and establish a power battery cascade utilization and recycling management system.
There are many kinds of pneumatic pipes, which are generally produced with PU raw materials, with stable quality, high pressure resistance, weather resistance, wear resistance, zigzag resistance, smooth and flexible pipe body, bright color, high elasticity, winding resistance and small bending radius.
The tube body is smooth and flexible, bright color, high elasticity, winding resistance and small bending radius. Temperature range: - 15 - + 70 ℃. Pu Pneumatic Pipe,Pu Air Hose,Pu Pneumatic Hose,Pneumatic Spring Hose, Pu Pneumatic Hose Tubing Glove Industry Co.,Ltd. , https://www.glovemech.com
Product classification
1. Pu pneumatic pipe
2. Pu (polyether) pneumatic pipe
3. Pu (polyurethane) bobbin
4. Pu (polyether) bobbin
difference:
Polyurethane pneumatic pipe is over air type. If it is used for over water, its service life will be affected,
Polyether pneumatic pipe can pass air or water, with more stable physical properties and longer normal service life. It is an ideal material for pneumatic pipe.
The bobbin is wrapped with a layer of fiber in the middle of the common pneumatic pipe. Therefore, the bobbin is more solid, pressure resistant and non explosive than the common pneumatic pipe.
Product selection
What should be considered when choosing the type of plastics for blow molding pneumatic pipe?
The following aspects should be considered in the selection of pneumatic pipe materials.
Whether the wall thickness of the welded blank of the pneumatic pipe can be kept uniform, whether a higher blowing pressure is needed, whether the blowing is uniform, whether the surface of the pneumatic pipe is bright, whether the demoulding is easy, and whether the strength can meet the requirements, etc.
Performance comparison of plastics for blow molding pneumatic pipe. The pneumatic tube formed by blow molding is in thermoelastic state, and its density is smaller than that after cooling and shaping, resulting in shrinkage. For the general size of pneumatic pipe is not strict, forming shrinkage has little effect. But for the pneumatic pipes of specified size, such as some hoses used in precision machines, large shrinkage has a considerable impact. The larger the blowing volume is, the more significant the effect is.
The advantages of extruding and blowing plastic forming pneumatic pipe are less investment in production equipment, simple equipment structure, easy mold manufacturing, high forming of pneumatic pipe during production, uniform temperature control, and various specifications of pneumatic pipe can be formed. The disadvantage is that the wall thickness uniformity of pneumatic pipe is poor.
The advantages of injection blow molding pneumatic pipe are that the plastic pneumatic pipe has good product quality, accurate dimensions, no seams, uniform wall thickness, multi-mode molding production, high degree of automation, which is very suitable for large-scale high-efficiency production of small specifications. The disadvantage is that the investment of equipment and molding die is large, and the operation and production need skilled workers.

Tips for pneumatic pipe
Polyurethane pneumatic hose is suitable for compressed air, ordinary industrial water and non corrosive oil. In order to maintain a long service life, it must be used under rated working pressure and ambient temperature. As the temperature rises, the working pressure should be reduced accordingly. If it exceeds the limit, the hose may break. If the fluid temperature is too high or the fluid is corrosive, the hose may break. If the working environment temperature is too high or there is chemical gas in the working space, the hose may crack. If the hose is stored in a wet place or the storage period is too long, the hose may hydrolyze or age, which may lead to fracture
