　　Vacuum technology development and prospect

　　The 20 th century, vacuum the development of industry are remarkably, arouse the attention. Vacuum science and technology in scientific research is just a kind of experimental technology, and in the modern industrial production have become a basic technology and widely used.

　　So, the industry of the vacuum to investigate whether the development in the technical aspects of the great invention or discovery? Not at all. And the whole world vacuum the cause of development of the industry just because other industrial technology of vacuum field increase in demand. The vacuum equipment manufacturers such as Japan's sales, only the electronics industry is 40% or so, is that a field to vacuum technology needs to increase.

　　In the 21 st century, and how to develop industrial vacuum, rely on the needs of the development of the what is? In the science and technology unceasing development today, vacuum technology and will have what new role? Also achieve what new achievements? This many unknown problems, concerned, worth thinking.

　　In the past, we talk about the development trend of the vacuum technology, usually go to find academic papers and patents material, in order to understand the physical phenomenon of vacuum condition, the application of vacuum get and measuring instruments such as the progress. And now we should change the past practice, hold on to the vacuum demand from this relationship, side to look forward to the development trend of the vacuum technology. That is, some important should vacuum application fields and discussed the relationship between the vacuum technology, to look forward to the 21 st century the development trend of the vacuum technology itself.

　　A, the need to constantly expand vacuum application fields

　　In the 21 st century, vacuum demand is growth or decrease? The development trend of the future and how will it? It mainly depends on the vacuum field where the application of whether to increase demand, whether growth.

　　In 20 to 30 years ago, vacuum books in the application of vacuum technology is pointed out that, by a pressure difference, 2 it is through the space of electronic or molecular remove interference, three is to reduce the number of particles hit the surface. Used for their different needs, the vacuum degree necessary of course is also different. The so-called rule out, that the particles space obstacles mean free path to the characteristics of long size than device. Vacuum evaporation, vacuum tubes and the accelerator is to use the vacuum of this feature. In addition to the power vacuum tube outside, most of the other solid components, this made no longer need to vacuum. Thermos is vacuum technology in People's Daily life, important application of later if can produce excellent insulation materials, and is very cheap, so in the production process of vacuum thermos will lose their effect. Reducing surface particles from the necessity of incident frequency look, ultra-high vacuum technology will develop, it can make the surface long maintain its clean. At present, the application of vacuum technology of the features are: using vacuum environment to develop some new materials and new technology. Make the vacuum application areas to be expanded further. For example superfine powder and nanoparticles production and solid component technology development. Another application fields are in order to reduce the chemical reaction process and the fusion reaction are not pure, sometimes also want to use that vacuum. The vacuum chamber the wall itself and the reaction process is very close relationship.

　　The demand for vacuum people will be enlarged. Such as Japan mitsui products company with a lead of aluminum, then use the high temperature makes aluminum evaporation, to use this method to smelting aluminium will expand to the needs of the vacuum pump. So, for vacuum equipment factory is a big vacuum pump sales market. The past smelting aluminium by electric solution, is now in the furnace reduction method. In the furnace reduction, as the refractory materials and aluminum mixed, separated very difficult. If the melting pot containing the aluminum appear not pure dissolved in solution can lead to contain the aluminum of lead and not pure, conduct separation. Use vacuum can separate the mixture in form of aluminum lead. This shows, the emergence of new technology, it will directly affect the vacuum to the needs of the industry, vacuum it has increased dramatically. A few years ago in China tried the emergence of magnesium process vacuum, vacuum equipment factory production once make the rotary pump and ROM watts pump in short supply. Cause deformity development. But it also explain a problem, namely the new technology, new material, certainly will appear to drive development of industry and vacuum.

　　In the 2 l century, surface treatment, the surface technology to become a large one vacuum application fields. Because people on the material requirements of reliability, especially for the application of surface technology will be increased. Now people are like using antirust, prevent oxidation material. Although aluminum alloy has produced, but original technology improve slightly, will be in a change in performance, if use oxidation film will materials and atmospheric space, can satisfy the requirements of users. This kind of situation, as long as the clue and vacuum manufacturer cooperation can develop a considerable market. And as for the past super pure aluminum foil method is very trouble, and vacuum equipment to the project application of the production process, will produce better ultra pure aluminum foil. If vacuum manufacturer can actively involved in this application fields, the people to the needs of the vacuum natural will greatly strengthened.
