Hosted by China National Machine Tool Corporation, the 7th China International Machinery and Equipment Exhibition and the 8th China Machine Tool & Tools Fair Exhibition (CIMES CMTF2006) hosted by Beijing Guoji Exhibition Center will be held on June 12, 2006. -16th held at the China International Exhibition Center in Beijing.
CIMES&CMTF2006 will continue to adhere to the principle of “serving exhibitors†with the theme of “strive to push the development of China's national machine tool industry and showcase new technologies and products of the world's machine tool industryâ€. After hard work and preparation, nearly 1,000 exhibitors from 25 countries and regions including China, Taiwan, and Hong Kong SAR will be exhibited at the exhibition, with a total exhibition area of ​​75,000 square meters, and all 16 exhibition halls of the International Exhibition Center will be rented. Including two temporary exhibition halls, the scale of which is the largest of the previous CIMES & CMTF, and the largest exhibition in China this year.
This year's exhibition brought together nearly 1,000 machine tool companies at home and abroad, including 252 overseas companies. Registered 85 companies (excluding provinces and municipalities) with an exhibition area of ​​more than 100 meters, including 27 overseas enterprises. Enterprises over 100 meters increased by 31% compared with 2004. The domestic well-known enterprise Dalian Machine Tool Group Co., Ltd. reported a total exhibition of 750 square meters, and the United States Haas Automation Company reported an exhibition of 800 square meters. The booth area of ​​Jiangsu Province, Shaanxi Province and Tianjin, which was subscribed to by the provinces and cities as a group, increased. The largest booth area in Jiangsu Province is 2,700 square meters, which has greatly exceeded the 2004 exhibition.
This exhibition insists on the development of China's national machine tool industry and promotes independent innovation. The exhibition exhibits domestic machine tool products and dominates the world. Famous manufacturers and manufacturers from Hong Kong and Taiwan actively participate. The characteristics of domestic machine tools are: metal cutting machine tools continue to develop to high speed, high performance and high precision; machine tool numerical control rate is further improved, high-speed machining center varieties continue to increase; five-axis linkage, pentahedron processing, parallel machine tool exhibits continue to innovate The number of independent innovation technologies and exhibits has increased. Metal forming machine tools continue to develop in the direction of numerical control, high speed and high performance, and domestic specialized machine tools and rapid prototyping technologies are steadily mature. Internationally renowned exhibits include horizontal and vertical machining centers, CNC lathes, CNC grinding machines, CNC forming machines and measuring machines with advanced technology in the world.
This exhibition focuses on the invitation work of customers and audiences. The organizing committee of the exhibition focused on selecting the top ten industries and project unit users including aerospace, railway, ship and automobile, as well as the top ten automobile manufacturing enterprises, to visit and purchase machine tools. The organizing committee will also issue invitations for audiences and users at different levels, embassies (colleges) in Beijing, universities and colleges. Numerous technical seminars and professional forums will be held during the exhibition.
Welcome all colleagues who are keen on machine tool products, care about and support the development of the machine tool industry, and visit the 2006 Machine Tools Exhibition.
Some of the plastic variety that people will produce large, low price, wide use and wide influence is called standard plastic.Its connotation often changes with the development of time and science and technology.Important standard plastics are polyethylene, polypropylene, polyvinyl chloride, polystyrene and other varieties
standard plastics including polyethylene, polypropylene, polystyrene, PVC, acrylic - butadiene - styrene), poly (methyl benzene acid methyl ester and amino plastics and so on, its production accounted for more than 90% of the whole plastic production, so it is also called the large plastic varieties.
Merits and demerits
Compared with wood, metal, cement, glass and other materials, standard plastics have the following advantages and disadvantages.
Advantages: (1) easy to form, high degree of freedom of design;(2) easy coloring;(3) stronger than metal;(4) lighter weight;(5) easy to modify, easy to obtain required performance;(6) good electrical insulation;(7) good water resistance and no rust;(8) good chemical resistance;(9) production consumes less energy than metal;(10) as long as the waste plastics are treated well, the environmental damage and pollution will be less than other materials.
Disadvantages: (1) poor weatherability, especially in ultraviolet light, aging easily under uv light;(2) generate static electricity;(3) large thermal expansion coefficient and poor dimensional stability;(4) low surface hardness, easy to produce scratches;(5) poor durability and poor environmental stress cracking.
But with the continuous development of blending technology progress, as well as the standard polymer high-performance achievements, some of its insufficient gradually improved, broadens the application field of Standard Plastic, made of plastic in the position in the national economy more and more important.
Standard plastics has excellent performance, variety and versatility.Standard plastics can replace metal materials, cellulose materials and silicate materials with three traditional materials, and as the most powerful competitor of traditional materials.Standard plastics has been widely used in agriculture, light industry, textiles, electronic appliances, machinery, building materials, packaging and transportation and other departments, profoundly influences the whole development and the progress of science and technology, industrial and agricultural production in social development and national economic development, people's material and cultural living standards improve all aspects such as occupies very important position.
The purpose of standard plastics can be covered in the following aspects:
(1) Agriculture: various kinds of agricultural film, sheet materials, holding irrigation pipes, sprinkling irrigation pipes, fishing nets, breeding boxes, floating materials.
(2) industry: due to the electrical insulation of plastics, standard plastics are already used in the electrical industry to make insulating materials and packaging materials.Manufacturing parts and shells in electronic and instrumentation industries;Transmission gears and bearings in the mechanical industry;Chemical industry of various anti-corrosion containers, pipes, slots, tanks, etc.
(3) construction industry: Plastic doors, Windows, ceilings, floor leather, plumbing and pipe fittings, gas pipes and fittings, etc. are made from traditional materials such as wood and metal.
(4) Packaging: Various woven bags, packaging films, composite films, hollow containers, revolving boxes, corrugated boxes, packaging belts, foam plastics, etc.
(5) daily supplies: all kinds of plastic toys, toothbrushes, soap boxes, raincoats, tableware, utensils, slippers, etc.
(6) medical and equipment industry: all kinds of artificial organs, medical use infusion bags, one injection supplies, degradative medical materials.
(7) electric appliance industry: All kinds of office appliances and household appliances insulation, heat preservation, anticorrosive, moisture-proof housing, resistance to the tang, precise military components and so on.
Divisor in the above areas,standard plastics apply more extensive, at present, some standard plastics by modification to expand the application field, in the defense cutting-edge industry, transportation and aviation industry used as structural materials a lot.
