Dongfeng Shenyu natural gas vehicle configuration: Adopt D912 cab, girders 1, 92, front axle 2.7T, rear axle 7T, 6-speed gearbox, 8.25-20 tires, 140-liter double-sided gas cylinder, engine CY4102-N5K, 105KW, fuel natural gas, wheelbase 3800. Compared with natural gas vehicles and new energy vehicles, there are problems with new energy sources. The cruising range is 70 kilometers in one charge, and it takes 3 hours to charge once, which will cause secondary pollution to the earth and environmental problems will become more serious. Battery replacement is expensive, and the handling of battery charges is the biggest environmental pollution, and the quality of the battery is not enough. The natural gas vehicle plus-secondary gas can drive 380 kilometers. The state strongly advocates the gas station to change the gas station, 'for urban environmental protection, New China Five emission standards. Compared with natural gas and diesel vehicles, natural gas emission standards, carbon dioxide emissions are 9.44KG, and diesel carbon dioxide emissions are 70.68KG. Based on the above analysis, the use of natural gas is more economical, safe, efficient, and environmentally friendly than diesel, and more comprehensive national future energy. In the development direction, LNG is also recognized as the most high-quality energy, so the use of natural gas for diesel is in line with the long-term development of the country. The current price of natural gas is 2.86 yuan per cubic meter. Compared with the price of diesel oil, the theoretical calculations can be used to purchase natural gas vehicles and diesel vehicles. The fuel cost can be saved for 4 years, and a natural gas vehicle has been introduced in some local areas. The province implements a half-price for high-speed gas for natural gas vehicles. National policies will be gradually advanced. The global human being is calling for a blue sky for the motherland. Human beings need an environment without pollution and no need to spend money to buy green air. (This article comes from Xiagong Chusheng)
In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects.
PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.
the Degree of polymerization of SG5 is 1000. usually we also call PVC Resin S1000. Its K-value is K67.
