Geosynthetics of GCL

       Taian Hongyuan Geosynthetics Co., ltd. has been engaged in the production and sale of GCLs for many years. As a professional GCL manufacturer, what is the geosynthetic material of GCL? Today I will take you to analyze it together.

       GCL is a kind of geosynthetic material specially used for preventing leakage of artificial lake water features, landfills, underground garages, roof gardens, pools, oil depots and chemical storage yards. It is made of high-expansion sodium The basic bentonite is filled between the special composite geotextile and non-woven fabric. The bentonite impermeable pad made by needle punching can form many small fiber spaces. The bentonite particles cannot flow in one direction and form in the pad when it meets water. The uniform and high-density gel-like waterproof layer effectively prevents water leakage.

       The mineralogical name of bentonite is montmorillonite, and natural bentonite is mainly divided into sodium and calcium based on chemical composition. Bentonite has the characteristics of swelling with water. Generally, when calcium-based bentonite swells, its expansion is only about 3 times its own volume, while sodium-based bentonite absorbs five times its weight of water when it encounters water, and its volume expands to 15-17 times its original In the above, the sodium-based bentonite is locked between two layers of geosynthetics to protect and strengthen, so that GCL has a certain overall shear strength.
