Wacker Starts Constructing Pyrogenic Silica Plant in Charleston

位于慕尼黑的化学集团瓦克化学股份有限公司正式开始建设位于瓦克查尔斯顿TN多晶硅厂附近的HDK气相二氧化硅装置。来自政界，商界和地方政府的代表参加了奠基仪式。瓦克执行董事会成员，田纳西州奥古斯特威廉斯高级官员和当地官员打破了新工厂的立场。

With the USA being the second largest chemical market, the Charleston, TN HDK pyrogenic SILICA plant will enable Wacker to keep pace with growing demand for this indispensable product,” said Auguste Willems. “This new facility is a key component of Charleston’s supply chain. It is the next step toward expanding Charleston into a fully integrated Silicon site,” he explained, emphasizing the strategic importance of Wacker's investment.

The main by-product of polysilicon manufacturing is Tetrachlorosilane. This either has to be converted and fed back into the production loop, or it can be used to create added-value by being further processed into HDK. By integrating the polysilicon and HDK production systems, Wacker achieves optimum flexibility in reprocessing tetrachlorosilane into a marketable product.

“HDK在油漆和粘合剂中用作流变控制添加剂，用作有机硅弹性体的填充剂，也可用作个人护理产品和化妆品中的助流剂，并在制药和食品加工行业用作抗结块剂。
