Recently, the Hubei Province government issued the "Decision on Science and Technology Awards of Hubei Province in 2023." Yihua Group won two awards for awards. Among them,"Key Technology and Industrialization of Green Production of Calcium Carbide PVC Multi-Catalytic Segmented Regulation and Polymerization" won the second prize for scientific and technological progress, and "Key Technology and Application of Safe and Efficient Mining of Complex and Refractory Phosphate Mines-Integrated Light and Gravity Flotation Sorting" won the third prize for scientific and technological progress.
"Key Technologies and Industrialization of Green Production of PVC Multi-Catalytic Segmental Regulation and Polymerization by Calcium Carbide Process" has made major innovations in the integration of key technologies and industrialization technologies, forming a complete recycling industrial chain of "production-use-recycling" catalysts. The overall technology of the project has reached the international leading level, and the research results have been widely used in many large catalyst production companies and PVC chemical companies such as Guizhou, Hubei, Xinjiang, Anhui, Inner Mongolia, Qinghai, and Shaanxi. The Chinese market share of carbon molecular sieve low-solid mercury catalyst products exceeds 60%, providing the necessary catalyst for the healthy development of China's calcium carbide PVC production industry and enhancing the competitiveness of China's PVC materials in the international market.
"Safe and efficient mining of complex and difficult to handle phosphate ores-Integrated Key Technologies and Applications of Light, Heavy and Float Separation" is aimed at major problems such as low recovery rate, difficulty in safety monitoring, and poor ore sorting effect in China's local phosphate ore mining. After years of research on theory, technology, equipment and industrial application systems, it has formed a complex gently inclined phosphate ore filling method mining and production process management, ground pressure monitoring, early warning and support control, light and heavy sorting and tail throwing and underground filling, Complete sets of technologies and engineering demonstrations for efficient development and utilization with independent intellectual property rights such as pre-concentrated phosphate rock normal temperature reverse flotation.
