At present, the main producing areas of engineering mud bentonite in China include Liaoning, Shandong, Hebei, Jiangsu, Anhui, Gansu, and other places, among which the quality of engineering mud bentonite produced in Fushun City, Liaoning Province is the best. The bentonite deposits in this area are rich in natural kaolinite, montmorillonite and other components, with high ore purity, advanced processing technology, stable quality of engineering mud bentonite produced, and excellent product performance. The use method of engineering mud bentonite is relatively simple. Firstly, the bentonite powder needs to be placed in water and stirred evenly to form a dense slurry like substance. Subsequently, mud is injected into the drilling or grouting holes to provide thickening, lubrication, and stability during the construction process. In addition, during use, some chemicals and additives can be added as needed to improve the performance and effectiveness of the product. Engineering mud bentonite products have many advantages. Firstly, it has excellent thickening and lubrication properties, which can effectively control the viscosity and flowability of the mud, prevent mud splashing and leakage. Secondly, engineering mud bentonite has good stability and can prevent the infiltration of groundwater and soil collapse. In addition, it also has good environmental performance and will not cause pollution to the surrounding environment and water sources. In short, as a commonly used building material, engineering mud bentonite has a wide range of applications and excellent performance. We hope that through continuous research and innovation, we can produce more high-quality, efficient, and environmentally friendly engineering mud bentonite products, providing more high-quality and reliable support for construction and geological exploration fields.
