四川成都汇丰化工厂开发成功一条年产 50 0ｔ高纯纳米氧化锌的生产线 ,并已投入批量生产。经检测 ,所生产的高纯纳米氧化锌粉材 ,其纯度大于 99.7% ,平均粒径为 2 0ｎｍ ,生产成本仅为进口同类产品的 1 10。粒径达到纳米级的氧化锌粉末 ,在磁性、内压、热阻、光吸收、熔点、光 Chengdu, Sichuan HSBC chemical plant successfully developed an annual output of 50 0t high-purity nano zinc oxide production line, and has been put into mass production. After testing, the production of high purity nano-zinc oxide powder, the purity of more than 99.7%, the average particle size of 20nm, the production cost of imports of similar products is only 10%. Zinc oxide powder with nano-sized particle size has excellent magnetic properties, internal pressure, thermal resistance, light absorption, melting point, light
