Special engineering plastics need industrialization
Due to its high heat-resistant grade, radiation resistance, corrosion resistance, fatigue resistance, high strength, wear resistance, and good electrical properties, PEEK has been used in aerospace, military defense, electronics, medical and health, and automobile manufacturing. It is widely used in home appliances and other fields and has become an indispensable key material. At present, in the international market, the price of PEEK is more than 100,000 US dollars per ton. In the Audi A6 sedan of FAW-Volkswagen, 44 parts made of polyetheretherketone resin are manufactured by British Victrex company, and the price is very high.
Polyether sulfone and polyether ether ketone are one of the main varieties of special engineering plastics. Polyether ether ketones, which came from the 1960s to the early 1980s, took about 20 years. Major European and American companies have invested a lot of manpower and financial resources to conduct research and development on special engineering plastics. Since the beginning of this century, international large-scale petrochemical companies have sought high-performance special engineering plastics cutting-edge technology and competed to enter this field and regard it as a magic weapon to enhance competitiveness. Therefore, the industry has designated special engineering plastics as the "pyramid tip" of the plastics industry. .
The research of China's special engineering plastics began in the early 1970s and started almost at the same time with the international community. It has been listed in the national key scientific and technological research projects of the "Seventh Five-Year Plan", "Eighth Five-Year Plan" and "Ninth Five-Year Plan" and the "863". plan. Prof. Zhongzhong Wu from the Polymer Laboratory of the Department of Chemistry at Jilin University has become one of the earliest specialists in the field of engineering plastics. After many years of unremitting efforts, Kyrgyzstan science and technology personnel led by Prof. Wu Zhongwen have completed laboratory and pilot production of polyethersulfone resin and polyetheretherketone resin, and obtained a number of national invention patents, making our country a successor in this field. After the United Kingdom, the second country in the world has completely independent intellectual property rights. After approval by the Ministry of Science and Technology, Jida established the National “863†Program Special Engineering Plastics Research and Development Center under the leadership of Prof. Zhang Wanjin. After the approval of the Ministry of Education, the company established the engineering research of the Ministry of Education of the Ministry of Education under the leadership of Prof. Jiang Zhenhua. center. This is also the only two national R&D centers in China that focus on the research and development of special engineering plastics. So far, it has undertaken more than 40 national-level scientific research projects and obtained more than 30 national invention patents.
China's achievements shake the West. Soon, users and manufacturers in developed countries such as the United States, Britain, Germany, the Netherlands, and Japan all visited Changchun. In addition to the trial purchase of samples, more is to negotiate joint ventures and cooperation matters. However, it is understood that in fact, a considerable number of foreign investors are ulterior motives. They are not unable to produce such products, but are worried that the Chinese will use price advantage to shake their monopoly status. Therefore, the conditions for joint ventures and cooperation are absolute control. It is not difficult to see that giants of foreign-made special engineering plastics have established joint ventures with China, and their real purpose is to monopolize the global market.
At present, Chinese Academy of Sciences, institutes of chemical engineering, and major universities all have a large number of research forces in the field of polymer science. The progress of laboratory research is not much different from that of foreign countries, but the progress from basic research to pilot and industrialization is There is a big difference from abroad. It takes only a few years or more than ten years for each breed from abroad to succeed in its development and industrialization. From the 1960s to the early 1980s, polyimides, polyetherimides, polysulfones, and polybutadienes were completed. A total of seven varieties of aromatic esters, polyphenylene sulfide, polyether sulfone, and polyether ether ketone have been used in the industrialization of special engineering plastics. In China, since the end of the 1960s, although all of the above 7 varieties have already completed laboratory studies, except for polyphenylene sulfide, which can be said to have achieved initial industrialization, other varieties are far apart.
Maximum load: 2000kg
Used to transfer materials overhead, our Light Girder Suspension Crane is especially suitable for use in workshop that have low ceilings as well as factories and sites made of lightweight steel frames where the bridge Crane reaches its limit.
The modular design contains fewer standard parts that make crane assembly as easy as stacking blocks. With these modular parts, users can reassemble a new crane, according to the change in lifting requirements of the alterations made to the workshop.
Due to the ultra-light weight of the crane, there is little friction between the trolley wheel and the rail. Easily moved by hands, this Suspension Crane can move clumsy, heavyweight workpiece in a fast manner. Available also with the mechanical electrical Chain hoist, hoist drive, electrical control device, and matched system, the crane requires limited maintenance and has a long service life.
This series of crane can run on both straight and curved rails. By using many other modular parts, it can be reassembled to become the single-girder or double-girder crane. Each of the modular parts is bored to the standard connector for its size. So the crane can be adjusted according to the layout of the worksite, in order to suit the specific material handling requirement and satisfy customer specific needs.
