The earthquake and tsunami in Japan on March 11 caused a large number of enterprises in the northeastern Japan to close down, and accounted for 70% of Japan's crystalline silicon solar cell silver (aluminum) pulp production was seriously affected. As this product belongs to nano-grade high-tech materials, currently there are only a few companies in Japan, China, and Canada in the world. This brings development opportunities to the only Ningbo Guangbo Nano New Material Co., Ltd., which is engaged in the research and development of ultra-fine powder production in the country. The company currently owns 26 physical-gas-process metal powder production lines with independent intellectual property rights, and the physical gas phase method has the advantages of less pollution and high quality compared with the chemical production of Japanese companies. Since 2009, the company's sales have increased at a rate of 100%. In 2010, it produced 400 tons of silver (aluminum) pulp and sold 140 million yuan. The products accounted for 20% of the international market. The next day after the earthquake in Japan, Guangbo Company dispatched personnel to visit Japan. In view of the current market demand, the company will strengthen scientific research investment to ensure product innovation and advancement. By 2012, it plans to increase investment by 135 million yuan. It is estimated that it will produce 1,000 tons of aluminum paste and 100 tons of silver paste annually, with an additional sales of 500 million yuan. Yuan has become the world's leading crystalline silicon solar cell silver paste and aluminum paste manufacturer.
