Phosphate is one of the main downstream demand products of phosphoric acid, accounting for more than 30%. It is one of the natural components of almost all foods. It is widely used in food processing as an important food ingredient and functional additive. my country is rich in phosphate and phosphate products and has a large production scale. There are about 100 varieties and specifications of phosphate and phosphide products, and Zongsheng has a production capacity of nearly 10 million tons. The main products are phosphoric acid, sodium tripolyphosphate, sodium hexametaphosphate, feed phosphate, phosphorus trichloride, phosphorus oxychloride, etc.

At present, the demand for traditional bottom phosphate products in China is sluggish. Due to the "eutrophication" problem of traditional phosphates such as sodium tripolyphosphate, the content of sodium tripolyphosphate in washing powder gradually declines, and some enterprises gradually replace it with other products. Sodium tripolyphosphate, the demand of downstream industries is reduced. On the other hand, the demand for fine and special phosphorous chemical products such as medium and high grade phosphoric acid and phosphate (electronic grade, food grade), compound phosphate and organic phosphate is growing rapidly.
