The two men rented a factory with an area of less than 500 square meters along the street to start producing and selling the following two products: sodium dihydrogen phosphate and disodium hydrogen phosphate. 

They officially launched trisodium phosphate and potassium dihydrogen phosphate, beginning to gradually occupy the market share.

Under the constant innovation and development, the total output was doubled.

Sewage treatment has gradually been paid attention to and implemented. As a high-quality product that can be used in sewage treatment, the phosphate products are sold well and the output was tripled. Because of the restriction of space and equipment, Ningbo Yinzhou Chaoyang Shengda Chemical Factory has been moved into a new standardized factory and the infrastructure is more complete. 

Ningbo Yinzhou Chaoyang Shengda Chemical Factory has been developing steadily, and striving for high-quality and efficiency. It has a considerable market share in East China and will continue to pursue innovation and development.
