Alloy Fasteners Eliminate The Increasingly Energy-saving Environmental Protection Market

"Environmental protection, energy saving, security" and called the three themes of

the fastener industry, the rapid development of China's fastener industry has brought huge economic benefits to society and social wealth, but also produced the corresponding environmental problems. How to reduce the pollution generated accompany it in today's growing emphasis on environmental protection has become particularly important.

Since March 1, 2007 to respond 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 substance content of 6 shall not exceed the prescribed limits), promulgated implementation known as "China RoHs Directive" and "Electronic Information Products Pollution Control Regulations." Since then, both in the international market or domestic market, "China" are faced with a green bar.

How to cross the threshold? Europe and the United States experience in environmental protection in developed countries are worth learning, using new environmentally friendly material, titanium alloy conforms to the rise of the inevitable historical development.

Titanium and its alloys because of its low density (4.51g/cm3), strength (some up 1000MPa), more than strength, high temperature performance, the first to be widely used in aviation, aerospace and other industries, become indispensable to the military industry of structural materials. In addition, the titanium and its alloys, in many chemical medium excellent corrosion resistance and other comprehensive performance, but also be petroleum, chemical, pharmaceutical, sports and other civilian industry wide acceptance, to gradually replace all kinds of metal materials, metal jumped in a short time Materials used in the third.

Tracing the history of titanium, seriously long. Ti was found in 1789, 1908 Norway and the United States began production of titanium dioxide with sulfuric acid, in 1910 the first time in the laboratory were prepared by using sodium titanium sponge. In 1947, people began smelting titanium in the factory. Year yield is only 2 tons. 1948 DuPont (DUPONT) only with the production of magnesium tons of titanium sponge, titanium or titanium sponge marks the beginning of industrial production. Surge in output to 20,000 tons in 1955. In 1972, the annual output reached 200,000 tons. The hardness of titanium and steel, and besides it is only with the weight of almost half the volume of steel, titanium, a little heavier than aluminum, though slightly, its hardness than aluminum big 2 times. Now, space rockets and missiles, the large number of titanium instead of steel. According to statistics, every year the world for Astronautical titanium, has reached 1000 tons or more. Very fine titanium powder, or a good rocket fuels, the universe known as titanium metal, space metal.

Social harmony and harmonious enterprise, environment-friendly society, is to achieve sustainable development objectives, and always concerned about China's environmental problems, environmental protection has always been concerned about the fastener industry, profession, every fastener is not responsible, on the tight Firmware environmental protection can not be taken lightly. The future needs of the fastener business to take on more social responsibilities, meet environmental requirements has become a global trend. Fastener business to survive, they must abide by international rules of the game, to comply with the directives of environmental protection.
