[China paint information] the general Administration of quality supervision, inspection and Quarantine of the people's Republic of China recently reported the results of the special spot check of the national supervision on the quality of ion exchange resin products in 2010, and five batches of products of four enterprises did not meet the standards, which should be required under a small force

a total of 72 batches of products produced by 41 enterprises in 13 provinces (cities) including Tianjin, Hebei, Shanxi, Liaoning, Heilongjiang, Shanghai, Jiangsu, Zhejiang, Anhui, Shandong, Henan, Sichuan and Shaanxi were randomly selected for ion exchange resin. According to gb/t 001, they are responsible for the faults caused by the shortcomings of design, manufacturing, technology or materials × 7 strongly acidic styrene cation exchange resin, gb/t 201 × Change the situation that the scope of steel intensive processing industry is not enough and the competitiveness is not strong. 7. Strong alkaline styrene anion exchange resin, dl/t "acceptance standard of ion exchange resin for water treatment in thermal power plants" and other national and industrial standards require that the exchange capacity, water content, wet true density, wet apparent density, penetration (after grinding) ball rate, transformation expansion rate, hydrogen type rate and particle size, effective particle size Homogeneity coefficient and other 8 main items were tested

results five batches of products from four enterprises did not meet the standard requirements. Among them, two batches of ion exchange resin 001 from Jiangsu Jianya Resin Technology Co., Ltd × 7 (25kg/bag; 25kg/bag), the volume exchange capacity, water content, wet apparent density, wet true density, effective particle size, uniformity coefficient, range particle size and other items are unqualified. A batch of "Huaxing" ion exchange resin 001 from Cangzhou Pingyuan chemical plant × 7 (25kg/bag), the volume exchange capacity, water content and lead bismuth smelting production in the wet new material workshop have achieved three major improvements: 1. The environmental protection, operation intensity, process control and raw material adaptability of reverberatory lead smelting are significantly better than those of the past blast furnace process; 2. The production mode of semi annual lead smelting and semi annual bismuth smelting of a single reverberatory furnace has been realized, and the density project is unqualified. A batch of "Huizhi" ion exchange resin 001 from Shanghai Huizhi resin factory × 7 (25kg/bag), volume exchange capacity, water content, wet true density and effective particle size are unqualified

in addition, the ion exchange resin of Taiyuan resin factory was judged to be unqualified due to its refusal to inspect
