为了解表面活性剂(壳聚糖)对可溶性硅肥性能的影响,本文以多晶硅企业生产排放的含杂质氯硅烷为原料,采用"碱浸取+水热"法制备可溶性硅肥,结合XRD、SEM、BET等测试手段,研究不同壳聚糖含量对可溶性硅肥性能的影响.结果表明:当壳聚糖加入量为3%时,产物样品的组成颗粒变成了较为茂密的孔洞结构,其多孔结构使得可溶性硅肥更容易提取,其含量达到28.23%.本研究为实现硅资源深度利用、多晶硅产业绿色化生产提供理论支持.
Study on the conversion of chlorosilane containing impurities into soluble silicon fertilizer
Chlorosilane containing impurities emitted from polycrystalline silicon production is taken as raw materials to explore the effects of different content of surfactants(chitosan)on the perfor-mance of soluble silicon fertilizer.A method of"alkali leaching plus hydrothermal"is adopted for preparing soluble silicon fertilizer.The effects of different chitosan content on the properties of solu-ble silicon fertilizer are explored by XRD,SEM and BET.The results show that when the addition of chitosan is 3%,the particle composition of the sample becomes a finer porous structure.The porous structure makes it easier to extract soluble silicon fertilizer with a content of 28.23%.This study pro-vides theoretical support for achieving deep utilization of silicon resources and improving the green production process of polycrystalline silicon industry.
