In recent years, our country of caustic soda production increased dramatically, while traditional downstream demand for caustic soda has been scant, excess production capacity, weak market problems to be solved. The personage inside course of study to suggest, as the consumption of caustic soda, strengthen the field of inorganic silicon compound high value-added, high alkali consumption of product development, will be one of the effective ways to solve the caustic soda overcapacity.

In shandong shouguang recently held the first China news, high-end saline economic cooperation summit in 2009 in caustic soda production capacity of 27.93 million tons, the production of 18.91 million tons. At the same time, influenced by the international financial crisis, the chemicals industry since October 2008 hit from larger and starts falling, reduce the demand for caustic soda. In addition, caustic soda production affected by chlorine balance product polyvinyl chloride (PVC)
