Remember automatic repair robots in science fiction film? NASA invented a kind of new material, can automatically repair damaged parts in 2 seconds. This material can be used in spacecraft and military aircraft and tank hell automaticrepair.
The Australian news network reported on September 1, although the material is not like science fiction movies the liquid metal robot in the "terminator", intelligent repair and leave no trace, but it can make a spaceship and military aircraft or tank automatically repair the damaged shell. Scientists demonstrated in the experiment, with one or two polyester layer metal after is penetrated, because oxygen entered and mixed with them, polyester liquid rubber containing tributyl borane(tributylborane) produces chemical reaction, quickly harden and finally repair the damaged parts of the metal.
The researchers said: "this liquid rubber turns into solid after it contacts with air." At present, the material needs to be studied further, testing its application features. The material is likely to use to repair damaged holes on the spacecraft, as well as for military equipment, such as plane or tanks.
Besides, according to IFLScience reported on August 27, this self repair material is NASA developed by cooperation with scientists at the university of Michigan. Jim·Scott (Timothy Scott) of The university of Michigan explaned, this kind of material cannot be used as components individually, but need to mix with other materials. Scott said: our purpose is to repair damaged (hole) quickly.
Moreover, the characteristics of the material is, the thinner the faster it will work. In the experiment, the thickness of the materia plate is 1 mm. In the actual product, the material plate will be thinner, the possible thickness is less than one tenth or even one hundredth.

MIM parts are highly welcomed in military industry
Metal powder injection molding (MIM) technology can directly forming high precision and complex geometry, small parts, and wide applicable materials. After introduced into China since the 1970's, it has been rapidly developing in all walks of life.
Metal powder injection molding in the earlier application in the ordnance production in China, which mainly includes firearms, artillery shells and other components. Gun parts shape and structure is complex, due to special application environment and has a certain risk, determine the gun parts must have high quality, including mechanical properties, density, precision, etc. Traditional gun parts generally used forging blank as raw material production by machining, the machining can obtain pretty high quality of gun parts. But machining material utilization rate is low, especially in the production of gun structure parts, metal shell, etc., the utilization rate of material only between 15% to 20%, most of the materials are cut. And for small parts of guns (trigger, magazine catch, etc.), high strength material (carbon steel, etc.) production difficulty is big, the efficiency is low and is not economical.
Use a metal injection molding forming can make all kinds of complex shape parts, and overcome the machining
characteristics of low material utilization, can save a lot of metal materials, greatly reduce the processing cost. Because the metal injection molding has a variety of advantages, people began to use the process to produce all kinds of gun parts, for example, the main spring housing, hammer, trigger, magazine catch, inadequate safety, etc. With the development of metal injection molding and mature technology, metal powder injection parts occupies more and more proportion in the gun composition.
At present, the rifle in the ordnance, in addition to the big parts like gun body and gunstock, most of the rest metal parts is made by metal injection molding. In the pistol, charging, trigger and shell also use the injection molding parts. Metal injection molding has wide range of materials application, can produce all kinds of metal materials of gun parts, satisfy people demand of variety of materials on the application of the gun.
In addition, the quality of gun parts produced by MIM have good consistency and high density, and has the characteristics of less machining, most of the parts don't need to be machined and can reach the accuracy of requirement, this makes the metal powder injection parts occupies a considerable proportion in guns.

China hardware power tools is very popular in central Asia
In the Central Lake market near Bishkek, Kyrgyzstan Chinese businessmen Chang is working in his operating hardware electric tools workshops. Chang said China's hardware power tools are extremely popular in central Asia.
Central Lake market is central Asia's largest wholesale and retail market, the market is assembled with over ten thousand containers. The channel in the market is complicated as a labyrinth. The first floor is used as stores, the upper is temporary warehouse. Kyrgyzstan was the importance transportation station of the ancient silk road trade. Nowadays, Kyrgyzstan after years of development have become the distributing centre of China radiated to central Asia.Chinese goods shipped to some of the biggest wholesale market first, is the local commonly known as the "bazaar", and then diverted to Kyrgyzstan and the central Asia and other countries in Eurasia.
Despite the recent Kyrgyzstan joined the Eurasian economic union, tariffs will be improved to China. But the Chinese merchant still hope with their many years on the basis of the struggle for the "area" trade unicom to offer their own strength.
