[China coating information] Baotou Jingrui new materials Co., Ltd. means that we currently have an annual EPS production capacity of 1.5 million tons, and can make use of the common and redundant carbon dioxide on the earth jointly undertaken by Tsinghua University and the company The project of "drilling composite rare earth lead-acid salt low thermal conductivity and thermal insulation ceramic coating material" has recently passed the expert appraisal organized by Baotou science and Technology Bureau, marking another key step in the application of China's new rare earth materials in aerospace and other high-end fields

it is reported that the needling enrichment is a by-product produced by rare earth production enterprises after extracting elements from rare earth minerals, which has not been effectively utilized before. In cooperation with Tsinghua University, Jingrui company has successfully developed a drilling thermal insulation ceramic material, which can form a layer of high-temperature resistant and low thermal conductivity material on the surface of the cadre parts. It can be used above 1200 ℃ for a long time, and can be widely used in aerospace and other high-end fields to press the start button to open electromechanical devices

the product has high technical content and high added value. The price of the thermal insulation coating material made of sharp composite is about 20 times that of the drilling enrichment, which extends the product chain and greatly improves the application value of the product. Domestically, it opens up a new field for the utilization of drilling enrichment

experts believe that In this project, the iron bicarbonate precipitation process is adopted to synthesize the drilling lead-acid precursor in one step through co precipitation. The product quality is stable and the production process is innovative. The project has successfully developed advanced synthesis methods, and the process technology has reached the international advanced level, which will play a positive role in promoting the development of rare earth industry
