In terms of transportation, traffic lights, traffic signs, communications, unmanned central stations, household lamps and lanterns power supply, photovoltaic power generation, solar buildings, solar cars, satellites, aerospace casting products, space power stations, etc., can be powered by solar cells, with broad prospects for development. Problems to be solved: electrolyte corrosion, poor light transmittance, low output voltage shortcomings. Corrosion of the electrolyte causes life problems. The other cathode electrode needs expensive metal cover, which makes it impossible to popularize the solar cell with low cost and high efficiency. I hope we can get the guidance and help from experts. The main medium and high frequency electric furnace, super high pressure water mist pulverizing equipment, exposure aerosol pulverizing equipment, widely services in aerospace, information and communications, power electronics, metallurgical machinery, petrochemical, energy, transportation and other industries, has a staff of 40 people, technical developer 1 casting and die casting 6 people, the difference between the total assets of 4.8 million yuan, annual output value of 7 million yuan, 2010 net profit of 1.51 million yuan. Metal powder is the basic raw material of metallurgical industry. It has been widely used in many fields such as machinery manufacturing, chemical industry, electronics, gas, aerospace and so on. Its performance directly affects the quality of final products. Now the annual demand for metal atomizing powder in China has exceeded 100,000 tons, of which 40,000 tons need to be imported. With the development of economy, there is increased demand for metal powder in all walks of life, according to the statistics, developed the traditional powder metallurgy industry average annual growth rate of 7%, the average annual growth rate of casting technology of powder metallurgy industry in our country requires 7%, foreign trade is continuously enter, transferred to the China international machinery and electronic products processing, the average growth rate is higher, more than 15%, its market potential is tremendous. Therefore, it is very important to study the new technology, new equipment and new equipment of powder atomization.
