On November 2nd, 2015, Weichai grandly held the Truck Power Division of the Power Product Upgrade Technical Symposium in 2016. Under the testimony of representatives of major OEMs, agents and end customers, we released a series of new technologies and upgrades. Products, with strong technical accumulation and supporting strength, once again define new standards for the truck power industry. This seminar is a grand event for the truck power industry. The highlights of the new technology released on that day made the guests dizzying. In the morning, the seminar first introduced the high-end technology roadmap for heavy-duty commercial vehicle power rookie WP13 ; in the afternoon, it shared the new technical highlights of Weichai’s traditional superior products, Blue Engine’s power and mind power, and Weichai’s specialization in market segments. Power, natural gas engine, sharp power and other R & D investment and technical achievements. Weichai Power defines new standards for the industry, but fights strength! In this issue, Xiao Bian first led everyone to appreciate the style of Weichai WP13. In the follow-up, Xiao Bian will also introduce the new technologies of Lan Qing Power and other products, and how they will affect the future development of the industry. High horsepower WP13 leads the industry into the "500+" era In January 2015, Weichai WP13 was released in Beijing. Today, the WP13 of “Technology, etc.†is like a “customer harvester†and has won numerous customers' dedication and its footprints have spread all over the country. On November 2nd, at the time of the 2016 truck power product upgrade technology seminar held by Weichai, we also invited leaders from Shaanxi Auto, FAW and Dayun to host the launch of the 5,000th WP13. The arrival of Weichai WP13 has set off a new trend of upgrading China's heavy truck market to large horsepower. Recently, a number of 13-liter 500-550 high-powered heavy trucks were launched by Shaanxi Automobile, Qingqi, Dayun, Beiben and other OEMs. Contrary to the uptrend, a dazzling market was painted for the low-lying market. With the help of WP13, these over 500 horsepower high-end heavy trucks have become China's first landmark products to enter the “500+†platform, leading the new era of 13-liter high-power heavy trucks. After a period of market trials, Shaanxi Automobile and FAW and other OEMs appreciated WP13: the entire vehicle was matched and optimized, the life of diesel engine B10 exceeded 1.5 million kilometers, the power range covered 480Ps—550Ps, and the engine’s economic speed was extended down to 950 rpm. The maximum torque range is wider, the range of fuel-saving vehicle speed is wider, and the dynamic performance has reached the top level of the international engine with the same displacement; the low fuel consumption is the biggest advantage of its differentiation. The fuel consumption per 100 kilometers is about 3 liters. Less than one year after its launch, WP13 has achieved full-scale support. From commercial vehicles and engineering machinery to ship power, WP13 is an ideal power option for upgrades in various market segments. Especially in the high-speed standard tractor market, WP13 once again defines new industry standards. It is reported that the proportion of tractors in the heavy-duty truck industry is 48.50%, while the proportion of road transport logistics (high-speed standard tractors) in tractors is 65.6%. Weichai explained the needs of this segmented market with “five changesâ€: that is, speeding up of highway freight, saving energy consumption, high efficiency of freight cycle, comfort of vehicle requirements, and clean vehicle emissions. In response to demand, the WP13 adopts the first smart energy-saving system integrated with a rear axle and autonomous ECU with a small speed ratio, and an electronically controlled clutch fan with closed-loop control. It has its own large displacement, low fuel consumption rate and low speed ratio, rear axle, and intelligent fuel economy. The application of the system has redefined the power standards, fuel consumption standards, safety standards, smart standards and reliability standards for the power of heavy commercial vehicles. Yan He, an engineer of Qingdao FAW Technology R&D Department, took part in the whole process of the WP13 trial with the new FAW Tianqi V model. He was very positive about the performance of WP13: “We have carried out the whole vehicle thermal balance, dynamics, economy, NVH, etc. The overall performance of the test was good, especially in the heavy-hub test, the fuel consumption per 100 kilometers of the road spectrum was 2-3L higher than that of competing products, the fuel consumption from Qingdao to Weifang was about 30L per 100 kilometers, and the power was strong. Kilometers." Coincidentally. Mr. Zhao Jia, a tractor customer from Hebei Xinji, also appreciated WP13: “My car is a 6×4 tractor, matching Weichai's WP13, and it mainly runs Shijiazhuang to Guangzhou Expressway, pulling leather, with a total weight of 53 tons. , all the way down, shift less, speed climbing is not hard at all, 100km fuel consumption 28L.After a trip down, can save five or six hours, the province more than 300 yuan of oil money.Now run to 60,000 kilometers, there is no fault , follow-up I will also buy WP13." Regenerated Nylon 6 is also called nylon 6 recycled material, which is generally produced by melting and granulating nylon yarn, nylon yarn or nylon cloth, because nylon 6 not only has good wear resistance, heat resistance, oil resistance and chemical resistance And processability, but also has dimensional stability and excellent mechanical properties, is widely used in automotive industry parts, gears, bearings, fan blades, pump blades, fishing gear, bicycle parts and some precision engineering accessories.
4.cn112853534a discloses a fiber manufacturing process, especially relates to a regenerated nylon 6 fiber manufacturing process, which includes the following steps: Step 1, pulverizing nylon 6 waste; Step 2, adding catalyst and ethanol and dichloroethylene A mixed solvent of alkane; Step 3, after the dissolution, filter the undissolved solids in the solution; Step 4, cool and crystallize the nylon 6 in the filtered solution at a certain temperature into a nylon 6 solid; Step 5, place the nylon 6 solid in Drying in an oven at 100-120° C. for 3-4 hours to make the water content less than 5%; Step 6, adding additives to obtain a mixture; Step 7, melt spinning to obtain regenerated nylon 6 fibers. The invention uses nylon 6 waste to produce regenerated nylon 6 fiber, which realizes the recycling of nylon 6 waste and fully avoids resource waste and environmental pollution.

WP13 leads the industry into the "500+" era
3. However, nylon 6 will degrade during processing, resulting in the loss of molecular weight, affecting the melt strength and processability of the polymer, resulting in the inability of recycled or recycled materials to be used in occasions with high performance requirements, and even possible Being treated as waste is not in line with today's theme of green and low-carbon development. Therefore, how to recycle recycled nylon 6 materials to avoid resource waste and environmental pollution has become a hot research issue in recent years.
