“Protecting the environment, energy, security,” and invited the three themes of the closure industry, the rapid development of the conclusion of China- industry has brought great economic benefits for society and social welfare, but also similar environmental problems. How to reduce pollution is involved in today’s growing emphasis on environmental protection has become particularly important. On March 1, 2007 to EU environmental directives from China (RoHS Directive: Refers to the European market launch in electrical and electronic equipment, lead, mercury, cadmium, hexavalent chromium and other hazardous substances in 6 does not exceed the limits) restrictions were put into operation the implementation is known as “China’s RoHS Directive” and “Electronic Information Products Pollution Control Regulations.” Since that time, both in the international market and domestic market, “China”, a green bar. How can I cross the threshold to stabbing? Europe and the U.S. experience with environmental protection in developed countries must learn to use new environmentally friendly material, titanium alloy meets the inevitable rise of historical development. Titanium and its alloys, due to the low density (4.51g/cm3), power (up to several 1000MPa), higher than the strength of the high temperature performance of the first widely used in aerospace and other sectors become necessary for military-industrial materials. Moreover, titanium and its alloys, there are many ways to chemical corrosion resistance and unrealized performance, but also in the oil, chemical, pharmaceutical, sports and other civilian industry-wide acceptance, gradually replace types of metals, metal in a short period of time to jump, the third materials used. Trace the history of titanium, really long. Tues was discovered in 1789, 1908, Norway and the United States of America began to titanium dioxide, sulfuric acid, in 1910 for the first time in the laboratory were prepared using sodium titanium sponge. In 1947 the factory began to melt titanium. The yield is just 2 tons. 1948 from DuPont (DuPont), only for the production of magnesium t titanium, titanium or titanium primary industrial production. Surge production of 20,000 tonnes in 1955. In 1972, annual production reached 200,000 tons. Hardness of the titanium and steel, and this is also a weight of approximately half of the volume of steel, titanium, or slightly heavier than the aluminum, but slightly smaller than the hardness of the aluminum iso twice. Now space missiles, a large amount of titanium instead of steel. According to statistics, every year the world Astronautical titanium, reached 1000 tons or more. A very fine titanium powder, or a good rocket fuel, the universe is known as titanium metal, space metal. Social peace and a harmonious enterprise, environment-friendly society, the objectives of sustainable development, and always concerned about environmental problems in China, protection of the environment is always concerned about the closure industry, trade, each bracket is not responsible for, have a tight firmware protection of the environment can not be taken lightly. The future needs of the screw company to take on more social responsibility, compliance with environmental regulations has become a worldwide trend. Closing business to survive, they must comply with international rules of the game, follow the guidelines for the protection of the environment.
