In the industrial materials system, bentonite, a clay mineral with montmorillonite as its core component, plays a key role in various fields due to its unique physicochemical properties. CIM-TECH, as a professional integrated enterprise specializing in bentonite research, production, and services, has been deeply involved in this field for many years, possessing a profound understanding of bentonite’s characteristics and applications, along with extensive practical experience.

In the field of casting, bentonite is an indispensable binder for molding sand. The performance of molding sand directly affects the quality of castings, and bentonite can firmly bind sand grains through intermolecular forces, forming molds with sufficient strength. When the mold is subjected to the high-temperature impact of molten metal, bentonite undergoes a dehydration reaction, forming a rigid framework that maintains the stability of the mold shape and effectively prevents defects such as distortion and sand adhesion in the casting. At the same time, bentonite's gradual dehydration characteristic at hot temperatures provides allowance for the casting to shrink during cooling, reducing casting stress and ensuring dimensional accuracy. With a professional technical team and complete laboratory equipment, CIM-TECH produces bentonite products that perform excellently in the casting field, helping many foundries replace imported bentonite and lower production costs.

In the field of construction, the application of bentonite is also widespread and important. In seepage-proof projects, sodium-based bentonite can rapidly expand upon contact with water, forming a dense gel with strong sealing properties. It is often made into bentonite waterproof blankets and other materials, used in seepage prevention for reservoirs, landfills, subway tunnels, and other projects, creating a reliable "waterproof barrier" for the construction. In concrete production, bentonite can improve the workability and water retention of concrete. Its fine particles can fill the gaps between cement particles, enhancing the density and strength of the concrete, while also slowing down water evaporation, facilitating construction operations. CIM-TECH has an annual production capacity of 150,000 tons of sodium-activated bentonite, 150,000 tons of dried bentonite, and 100,000 tons of ground bentonite, providing the construction industry with stable, high-quality bentonite products to meet the needs of various construction projects.

CIM-TECH has always focused on technological innovation, continuously exploring the processing and application of bentonite. The company’s research and application laboratory is equipped with complete testing instruments and analytical equipment. The team, composed of domestic and international technical engineers, has accumulated extensive practical experience and can provide customers with high-quality technical services and products.
