It is capable of formulating the company's innovation plan, carrying out industrial technology R&D, creating and utilizing intellectual property, establishing a technical standard system, cultivating innovative talents, building a collaborative innovation network, and promoting the implementation of the entire process of technological innovation. Currently, the technology center has a total of 72 technical personnel, accounting for 23% of the total number of employees, with 40 technical personnel holding a bachelor's degree or above, and 38 technical personnel at the intermediate level or above.

　　Our company has accumulated 42 patents, including 9 invention patents. The R&D results have achieved good technology transfer. The "two-step method" process for producing Phosphoric Acid and the efficient air-cooled continuous crystallization process for producing Phosphoric Acid diammonium hydrogen phosphate are the first of their kind in the country. They address shortcomings, fill gaps, reduce energy consumption, promote the green development of the phosphorus chemical industry chain, and enhance the international competitiveness of our Phosphoric Acid salt products. The high-purity electronic-grade Phosphoric Acid produced using new melt crystallization technology meets the requirements of the International Semiconductor Materials Committee (SEMI) and has been recognized by domestic and foreign users, breaking the long-standing import situation. The precursor series products of Ammonium Phosphate, developed over many years for the positive electrode materials of new energy power batteries, have won users' favor with their innovative technology and first-class quality, becoming the largest supplier of raw materials for domestic new energy power battery positive electrode materials. We have become the production and sales base for fine Phosphoric Acid salts in China and a pillar enterprise in the subdivided field in Hubei Province.
