The group is an enterprise that extracts bromine from natural underground brine and uses the remaining brine after bromine extraction to produce raw salt. It then uses the raw salt to produce caustic soda and liquid chlorine through ion - membrane electrolysis. Its main business is the production and sales of chemical raw materials such as raw salt, bromine, caustic soda, liquid chlorine, and hydrogen. It is one of the large - scale production and R & D bases for salt chemical products in China.
Adhering to the business philosophy of "integrity as the foundation, customer first, strengthened control, quality first, continuous improvement, and striving for excellence", the group relies on rich underground brine resources, abundant land resources, advanced high - tech advantages, and scientific enterprise management advantages. It focuses on the R & D and production of deep - processed products in the salt, bromine, chlorine, and hydrogenation series. The products are diverse in variety, large in output, and high in quality. The production capacity and quality of caustic soda, liquid chlorine, bromine, and raw salt rank among the top in the country and the industry.
