Enhance quality awareness and promote high-quality development. ----------------------------------------- On September 6, 2023, China Pingmei Shenma Group’s R&D team, after more than two months of testing, successfully developed a new product: an impregnating agent for asphalt. This product has now entered the domestic market for ultra-high-power graphite electrodes, marking a successful transformation of the company’s technological innovations. It is understood that as the production volume of ultra-high power graphite electrodes in China increases, impregnation pitch, as a new type of filler required for their production, is being increasingly studied. In June of this year, the company held a project kickoff meeting and decided to use the pretreatment system of the needle coke plant for the pilot production of impregnant asphalt. The company established a technical task force led by its top management, comprising more than 20 key personnel from the needle coke plant, the technology center, and the production scheduling center, to advance this project with the full support of various departments. After hundreds of hours of adjusting production parameters and equipment, the impregnant asphalt production system has achieved stable operation over extended periods, with excellent results in all test indicators. On August 30, the company successfully produced two different grades of impregnator asphalt. Since the beginning of this year, in the face of unfavorable factors such as a sluggish market and low product prices, Shoucheng Technology Company has focused on market demands and relied on technological innovation to open up new business areas. The newly developed high-value-added products such as carbon black oil, binder asphalt, and impregnation asphalt have become new drivers of growth for the company. “The two types of impregnant bitumen we produced this time have one featuring a QI (quinoline-insoluble matter) content
