Sodium bentonite waterproof blanket is a natural anti-seepage material widely used in artificial lake construction. It is made from sodium bentonite particles, which are known for their excellent seepage resistance and high expansion coefficient. This environmentally friendly and high-performance material serves as an effective natural waterproof layer.
The sodium-based swelling waterproof blanket works by utilizing the unique properties of sodium bentonite. When exposed to water, it can expand up to 24 times its original volume, forming a thick, viscous colloidal system with minimal fluid loss. Enclosed between two layers of geotextiles, the bentonite expands in an orderly manner, leading to a dense and compact structure that effectively prevents water penetration. This process not only enhances the waterproofing performance but also provides a certain level of shear strength, making it a reliable and durable natural waterproof solution.
Due to its outstanding environmental protection characteristics, tensile strength, and anti-lining effects, the sodium bentonite waterproof blanket is ideal for use in waste landfills, underground reservoirs, and other infrastructure projects in environmental engineering. It effectively solves issues related to sealing, isolation, and leakage prevention, offering strong resistance to damage and long-term performance.
The quality of the sodium bentonite waterproof blanket largely depends on the quality of the bentonite particles used. Some types of bentonite have a high expansion coefficient and are suitable for waterproof applications, while others may lack this property and are not appropriate for such use. At our company, we source high-quality sodium-based bentonite particles from Jianping County, Liaoning Province. These particles are uniform in size, have a fine texture, and exhibit a high expansion coefficient, making them ideal for producing premium sodium bentonite waterproof blankets.
Coating multiple layers of dielectric films on optical components or substrates to change the direction of light wave propagation is suitable for applications ranging from laser beam processing to instrument construction and advanced imaging.
The dielectric reflector produced by our company has high reflectivity, wide reflection frequency band, and good compactness. The specific technical specifications can be customized according to customer needs.
