该项目位于青海省西宁经济技术开发区东川工业园区亚洲硅业(青海)有限公司厂区内西南角,由亚洲硅业(青海)有限公司投资建设,总占地面积10000㎡,总建筑面积3000㎡。新建年产1000吨气相白炭黑生产线1条,3000㎡钢结构生产厂房1座,年产1000吨纳米级气相白炭黑。工艺流程:项目利用原有工程多晶硅生产中产生的高沸物(四氯化硅Si Cl4)和低沸物(二氯二氢硅Si H2Cl2)采用闭口法新工艺生产纳米级气相白炭黑。项目总投资1200万元。
The project is located in the southwestern corner of Asia Silicon (Qinghai) Co., Ltd. in Dongchuan Industrial Park, Xining Economic and Technological Development Zone, Qinghai Province. The project is invested and constructed by Asia Silicon (Qinghai) Co., Ltd. with a total area of 10000㎡ and a total construction area of 3000 ㎡. A new annual output of 1,000 tons of fumed silica production line 1, 3000 ㎡ steel structure of a production plant, with an annual output of 1,000 tons of nanoscale fumed silica. Process: The project uses the closed-cell process to produce nanoscale fumed silica from the high-boiling (SiCl4) and low-boiling (SiH2Cl2) produced in the original project polysilicon production. The total investment of 12 million yuan.
