Since the major earthquake in Japan, Japanese car brands have been affected. According to the statistics of the China Automobile Association, the production and sales of domestic Japanese brand cars have apparently declined in April. It is expected that the sales in the second quarter will be seriously affected.
According to Yan Jinghui, deputy general manager of the Asian Games Village Automotive Trading Market, Toyota’s announcement that it expects to resume production in China will be significantly ahead of schedule, not only boosting the confidence of manufacturers and distributors, but also stabilizing market prices. Determine the role.
Previously, when the reporter interviewed the Asian Games Village Auto Dealing Market, it was discovered that sales of some models of Japanese brands had been out of stock, and orders for May delivery vehicles made by some dealers had also been rejected by manufacturers. The discounts on Japanese brand models have been reduced to About 50%.
Compared with the finalization of the domestic vehicle production schedule, the recovery of Japanese imported vehicles is obviously yet to be determined. Since the Japanese factory still takes intermittent production, the supply plan has been repeatedly revised, and dealers have said that consumers who are now booking imported models may have to wait for about six months, and bookings for individual hot models have stopped.
The head of the public relations department of Toyota China Bullock told reporters that this time Toyota resumed production in China, and the joint venture factory will return to a two-shift state of production. There is still a gap compared to the three shifts last year. Even if all production resumes, there will still be a certain lag in the supply of terminal markets. As for whether or not the sales plan will be adjusted due to the earthquake, Niu said that it still depends on the supply of spare parts in the future. At present, there is no clear conclusion.
It is reported that on April 22, Toyota issued the results of the assessment that "Overseas production will resume from August and then return to normal production levels from November to December." The recovery of production is ahead of schedule, and sales in the terminal market are also expected to increase in the third quarter.
It is worth noting that Dongfeng Honda and Guangzhou Automobile Honda also ended their two-week extension of maintenance after Toyota announced that production had returned to normal levels. They had officially resumed work on the 17th.
Yan Jinghui believes that with the recovery of the production of Japanese car companies, the supply of Japanese brand cars will gradually increase. As the company is facing greater sales pressure in the second half of the year, the terminal will also increase price concessions to stimulate the overall market. However, due to the fact that there is still a certain degree of climbing after the company’s production returns to normal, it may take longer before the market impact is eliminated.
PEEK Plastics,Polyether ether ketone, known in English as polyetheretherketone plastic (PEEK Plastics), is a linear aromatic polymer containing chain sections in the main chain of molecules.Its constituent units are oxygen-pairs of phenyl-oxycarbonyl - pairs of phenyl, semi-crystalline, thermoplastics.
Product name: polyether ether ketone (PEEK Plastics) resin is a kind of excellent special engineering plastics, PEEK Plastics has more significant advantages compared with other special engineering plastics, resistance to high temperature is 260 degrees, mechanical performance, good self-lubrication, resistance to chemical corrosion, flame retardant, stripping resistance, abrasion resistance, no strong sulfuric acid, nitric acid resistance, radiation resistance, strong mechanical properties can be used for high-end technology such as mechanical, nuclear engineering and aviation.
PEEK Plastics has heat resistance, chemical stability and the forming process of thermoplastic plastic. PEEK Plastics has excellent heat resistance.Its thermal deformation temperature of 160 ℃, with 20% ~ 30% Glass Fiber reinforced, heat distortion temperature can be increased to 280 ~ 300 ℃.Polyether ether ketone is good, the thermal stability of 420 ℃ in air.2 h under weightlessness is only 2%, at 500 ℃ was 2.5%, significantly thermo-gravimetric 500 ℃.Polyether ether ketone of long-term use of temperature is about 200 ℃, under this temperature, still can keep the high tensile strength and bending modulus, PEEK Plastics is also a kind of very strong material, has excellent resistance to creep and fatigue performance for a long time.
PEEK Plastics electrical insulating performance is very excellent, volume resistivity of about 10 ~ 10 Ω · cm.It still has small dielectric constant and dielectric loss in high frequency range.For example, in 10Hz, the dielectric constant in the room is only 3.2 and the dielectric loss is only 0.02.
The chemical stability of polyether ether ketone is also very good. In addition to concentrated sulfuric acid, almost any chemical reagent is very stable, even at high temperature, PEEK Plastics can maintain good chemical stability.In addition, PEEK Plastics has excellent heat resistance and steam resistance.In 200 ~ 250 ℃ steam can be used for a long time.
PEEK Plastics with good flame retardancy, in normal circumstances it is difficult to burn, even burning, smoke and harmful gas release a quantity to also is very low, even lower than low smoke volume of polymer such as ptfe.In addition, PEEK Plastics has excellent radiation resistance.Its resistance to alpha rays, beta gamma rays and gamma rays is the best current polymer material.The wire products covered with it can withstand gamma rays of 1.1 x 10Gy.
The polyether ether ketone has good fluidity and thermal stability at the melting point.Therefore, PEEK Plastics has the typical processing performance of thermoplastic plastic. Therefore, it can be used for injection molding, extrusion, blow molding and laminating, and also spinning and making films.Although the polyether ether ketone melt processing temperature range is 360 ~ 360 ℃, but because of its thermal decomposition temperature above 520 ℃, and it still has the very wide processing temperature range.
Although the development history of PEEK Plastics is only a short 20 years, but because PEEK Plastics has the outstanding heat resistance, chemical corrosion resistance, radiation resistance and high strength, easy to machining, PEEK Plastics is currently in the nuclear industry, chemical industry, electronic appliances, machinery, instrument, automobile industry, and has been widely used in aerospace field.In particular, thermoplastic resin, which is excellent in heat resistance, can be used as the base material of high performance composite materials.
modified
PEEK Plastics performance of the pure material is difficult to meet the different needs of different industries, in special working environment need to modification of PEEK Plastics, its main means blending modification, copolymerization modification, reinforced composite, infill modification, nanometer modification and surface modification technology.The modification can increase the performance of PEEK Plastics, such as wear resistance, impact strength, etc., thereby extending the application range of PEEK Plastics, reducing the cost of materials and improving the processing performance of PEEK Plastics.
Application
PEEK Plastics has been widely used in aerospace, automotive manufacturing, electronics, medical and food processing.
PEEK Plastics has excellent performance, its application field will be more widely with the domestic application research, the current domestic set up the chongqing sanxin materials research center is a professional engaged in the research of PEEK in the field of application.The research center is under the chongqing government entities at all levels of leadership and care, is committed to in the field of automobile, electrical and electronic fields, transportation research, in the present walk at the forefront of the domestic application research.
