目前国际国内市场硅微粉需求量大,国外客商大量到国内采购硅微粉,目前国内硅微粉价格近达2000元一吨,国内目前大多工业硅厂每生产三吨工业硅可回收一吨硅微粉。6300工业硅炉子生产一天能回收硅微粉3到4吨,回收价值可观。工业硅环保回收除尘的核心技术,国内经过多年的引进吸引, At present, domestic and international demand for silica fume large, foreign businessmen to a large number of domestic purchases of silica fume, the current price of domestic silicon powder up to 2,000 yuan a tonne, most of the current domestic industrial silicon plant produces three tons of industrial silicon recycles a ton of silica fume. 6300 industrial silicon furnace production day to recover 3 to 4 tons of silica powder, the recovery of considerable value. Industrial silicon environmental protection and recovery of the core technology, after many years of domestic introduction to attract,
