Anhui Xujing powder new material technology Co., Ltd., Anhui Province & ldquo; high tech enterprise & rdquo;! The company is mainly engaged in the research and development and production of new non-ferrous metal powder materials. It has 5 invention patents, 13 utility model patents, ISO9001:2008 quality system certification executive unit, the company has the right of import and export self operation, and has formed a model with an annual output of 2000 tons of various non-ferrous metal powder materials. The main products are all kinds of copper and copper alloy powder, including aluminum bronze powder, 6733 copper tin powder, 10 & 20 & 30 brass powder, 8 phosphorus copper powder, 13 phosphorus copper powder, copper nickel alloy powder, 663 & amp; 660 bronze powder, 10 copper tin powder, 37 tin lead alloy powder, surface modified pure copper powder and other products have reached the international advanced level of similar products. The products are exported to the United States, Germany, Italy, Australia, Japan, South Korea, Southeast Asia and other countries and regions, as well as domestic Shanghai, Jiangsu, Zhejiang, Guangdong, Shandong and other places. It is particularly noteworthy that many domestic enterprises purchase Xujing powder product copper powder or alloy copper powder as raw materials, with the quantity ranging from dozens to hundreds of tons, to produce organosilicon monomer synthesis copper catalyst or assistant. Xujing powder copper catalyst product has been produced in many domestic organosilicon monomer production, and the enterprise has been widely used and exported to Japan. It is reported that at present, Xujing powder has been built to produce an annual production capacity of 500 tons of copper catalyst. The laboratory performance test results show that the comprehensive performance is superior to that of similar catalysts in the market, and it can be supplied in batches at present. Su fabing, research team of Institute of process engineering, Chinese Academy of Sciences, has been engaged in the research and development of organosilicon monomer catalytic conversion for nearly ten years, applying for 25 invention patents, 15 of which have been authorized, and more than 20 articles have been published in international famous journals (such as journal of Catalysis) on the research results of catalyst preparation and catalytic mechanism. Xujing powder introduced the team's copper catalyst preparation patent technology in October 2018. Combined with Xujing powder's own production technology advantages in copper powder materials, the two sides jointly developed a unique high-efficiency copper based composite catalyst preparation technology! We have completed the small-scale laboratory test, pilot test and large-scale chemical industrial production. About the high efficiency copper catalyst for organosilicon monomer synthesis [appearance] Figure 1 product appearance (left) and scanning electron microscopy (right) [main components] Cu: 1-30%; Cu2O: 40-95%; CuO: 1-45%; addition of Zn, Sn, P, Al, La is less than 5%. Table 1 Analysis of product impurity elements other content of faaspbcdsb (PPM) ＜ 1000 ＜ 6.0 ＜ 1.1 ＜ 0.5 ＜ 1.0 ＜ 15.0 can be adjusted according to the user's demand. [particle size distribution] FIG. 2 product particle size distribution comparison Fig. 2 product median size result sample median size / & micro; M domestic catalyst-12.74 domestic catalyst-21.92 imported catalyst 1.69 Xujing catalyst 1.30 [bulk density] Table 3 product bulk density comparison table sample bulk density (g / cm3) domestic catalyst-11.88 domestic catalyst-21.79 imported catalyst 1.83 Xujing catalyst 1.60 [catalytic performance] all data below are completed under the same laboratory conditions. From the comparison data, we can see that Xujing catalyst The crystal catalyst products have the characteristics of short induction period, fast start-up, stable reaction process, high selectivity of dimethylmethane (3-5 percentage points higher than similar products), high yield of dimethylmethane and fast conversion of silica powder. Table 4. 24h performance evaluation results of product (325 ℃, fixed bed) catalyst Product selectivity (%) ; yield of second party a (right) [quality assurance] the performance of all the ex factory copper catalyst products of the company has been strictly tested by the Institute of process engineering, Chinese Academy of Sciences, and a test analysis report has been issued to ensure that all the performances of the products are qualified. [product trial] 1. Before trial use, both parties will work out a detailed trial plan according to the production process characteristics of the monomer production enterprise; 2. During the trial period, Xujing company and the technical personnel of the Institute of process of Chinese Academy of Sciences will track the whole process on site and make timely adjustments according to the production situation; 3. The price of trial copper catalyst product is lower than the market price at the same period, and the test cost of relevant personnel will be paid; 4. It can Compensation for the economic losses caused by the trial use of the product and recognized by both parties; 5. The packaging method and delivery conditions can be implemented according to the requirements of the silicone monomer enterprise.
