The Group is mainly engaged in R&D, production and sales of bentonite fine chemicals, and provides technical and equipment support. The Group uses bentonite as a raw material to produce papermaking chemicals, bentonite for metallurgical pellets, high-quality calcium-based soil and other products. The Group has national invention patents and authorizations, covering many of the Group's products, technologies, processes, applications and methods. The company won the “Third Prize for Scientific and Technological Progress in Zhejiang Province” and two “Second Prize for Municipal Science and Technology Progress”. Every year, the Group invests a significant proportion of capital in scientific research and development, innovation and technological innovation. Among them, the R&D center is equipped with a number of scientific research assets, instruments and equipment, professional software, etc. The Group's paper chemicals mainly include: retention aids, deinking agents, water purification agents and enhancers. According to the customer's specific production situation, the Group produces customized and suitable products for that customer in a timely manner to meet the customer's needs and give the best effect to the Group's products. Retention filter aid: The main function is to increase the retention rate of papermaking raw materials, speed up water filtration, and reduce papermaking production costs. Deinking agent: The main function is to remove ink from waste paper and use waste paper to produce a variety of paper products needed in the market. Water purification agent: The main function is to purify wastewater generated by papermaking and improve the recycling rate of wastewater. Enhancer: The main function is to increase the strength and quality of paper products. Among them, “bentonite for binary particle retention aid and filter aid” and “environmentally friendly multifunctional clay deinking agent” were recognized by the Ministry of Science and Technology as national key new products in 2008 and 2011, respectively. The metallurgical pellets produced by the Group use bentonite, which is mainly sold to steel smelters to bind iron ore powder for smelting to improve the production capacity and efficiency of blast furnaces in smelters. The high-quality calcium-based soil produced by the Group can be used in fields such as water quality purification in aquaculture, mildew inhibitors and binders for animal feed, and can also be used as raw materials for further processing of higher-end products. It is also an essential raw material for the Group to develop and produce high-purity water-washed bentonite. Other types of products mainly include organic bentonite and inorganic gels, which are mainly used in the paint preparation industry. The Group mines bentonite ore, develops and produces fine chemicals based on bentonite, sells them directly to industrial users, and provides customers with application solutions and equipment support. The Group has three marketing management zones in East China, South China and North China, and has nearly 30 technical and business specialists stationed in their regions to directly communicate with customers and develop business.
