Technical introduction of bentonite
The United States has always been a leader in the research of bentonite in the world, and many domestic standards for bentonite products are also based on American standards. Some European countries, Japan and South Korea also have more advanced technology on some products. Compared with foreign countries, domestic product and market development is relatively slow, and the products are mainly conventional products. This has a lot to do with the domestic environment, policy and resource status.
In the early days, the research and development of domestic bentonite was mainly concentrated in Zhejiang, and the production of relatively high-end domestic products was also concentrated here. The enterprises are represented by Zhejiang Huate and Zhejiang Fenghong. In recent years, many domestic universities and research institutes have also made great progress in bentonite research, and have a series of bentonite deep processing technologies. The more representative ones are Wuhan University of Technology, China University of Mining and Technology, China University of Geosciences, Suzhou Non-Mining Institute, and Zhengzhou Institute.
The strategic mineral of China Non-Metallic Mining Industry Corporation is bentonite. There are bentonite enterprises in Xinjiang, Hubei and Beijing. The products cover metallurgy, steel, drilling, construction waterproofing and other fields. Its technology center develops new products based on its subsidiaries, has a large number of scientific research achievements and independent intellectual property rights in technologies such as environmental protection, new waterproofing, and purification, and uses its brand advantages to form better alliances with universities, research institutes and enterprises in Beijing. With its unique advantages and technical expertise, it has formed a new R&D base in North China.
