Project mainly for calcined kaolin used in domestic thermal paper of oil absorption value is low and the particle size distribution width faults as well as products such as low quality, low value-added calcined kaolin, competitive advantage is not obvious, through system analysis included rock mineral composition and formation mechanism, combined with the actual needs of industrial production, after two years of trial and error, The relationship between raw material quality, process parameters and product performance has led to the development of high-end calcined kaolin products with oil absorption value of 80g/100, 2um > 92% and wear value < 20mg/ Rev. The technical level has reached the international advanced level. The successful development of the product quickly occupied the domestic market, and won the favor of foreign thermal paper manufacturers, and broke the monopoly of international kaolin giants basF and IMery.
This project is mainly aimed at the comprehensive utilization of gaolinite coal gangue in coal-based solid waste in coating, papermaking and other industries through dehydroxylation and decarbonization. However, due to the high content of iron and titanium, some gangue affect the physical and chemical indexes such as whiteness, limiting its further development and application, so as to carry out research and industrial transformation. Based on the high activity metakaolin mineral admixture, the cost of concrete can be reduced, the performance defects of ordinary cement concrete can be made up, and the service life of the project can be greatly extended
Up to now, the subject is based on silicon-plated gangue resources in Shanxi Province as raw materials. The preparation of high activity metakaolin powder material has been completed by wet and dry activation grading purification technology. The comprehensive indexes have reached the design requirements of the project. The performance evaluation of high performance concrete is being carried out to determine the appropriate mixing ratio. This project will further realize the high-value utilization of bulk coal measures solid waste, improve the comprehensive utilization rate of solid waste resources in our province, and increase employment and profits and taxes in this region.
This project intends to utilize the high quality coal measures kaolin mineral resources in north Shanxi Province to study and develop the key technology of preparing pigment grade high performance calcined kaolin. By studying the mineral composition and its behavior and physical and chemical properties in the process of grinding, calcination and post-treatment, the key technological factors affecting the properties of pigments were determined, so as to meet the requirements of pigment grade calcined Kaolin in the developing paint industry. Based on the developed technology, an industrial demonstration line of calcined kaolin with an annual output of 200,000 tons of high covering pigment grade has been established.
In this project, wet grinding system, homogenizing feeding device and heating and pressure boosting system are used to adjust the proportion of coupling agent and coating rate of finished product through parameters. To seek the best process parameters and develop new products suitable for the rubber and plastic field. The objective of the research and development of key products approved by the special screening and surface treatment, with rubber has very good crosslinking effect, it has good compatibility with the matrix material, good dispersibility, high purity and chemical inertness strong wait for an advantage, so can effectively improve the rubber material insulation performance, mechanical property and processing rheological properties, aging resistance and acid-proof alkaline, etc.
Now the raw materials of powder coating industry, equipment and so on are non-standard products, because of the same name of the product, the price is very different, cause a lot of influence to some regular enterprises. So there is an urgent need to list product standards, or composition content of product connotation.
