4.8kgGCL sodium based bentonite blanket, 4800gGCL sodium based bentonite waterproof pad

Description :

　　4.8kgGCL sodium based bentonite pad:

　　4.8kgGCL sodium based bentonite pad is a new type of geosynthetic material. It is made by uniformly mixing graded natural sodium based bentonite particles and corresponding additives. Through special processes and equipment, the bentonite particles are fixed between two layers of geotextiles to make a bentonite waterproof blanket, which has all the characteristics of geotextiles and excellent waterproof (permeability) performance.

　　The waterproof mechanism of the 4.8kgGCL sodium based bentonite pad is that the bentonite particles expand when they come into contact with water, forming a uniform colloidal system. Under the restriction of two layers of geotextiles, the bentonite changes from disorder to orderly expansion. The continuous water absorption expansion results in the bentonite layer reaching compactness, thus having waterproof effect.

　　Physical characteristics of 4800g GCL sodium based bentonite pad:

　　1. The 4800g GCL sodium based bentonite pad has excellent waterproof and anti-seepage performance, with an anti-seepage static water pressure of over 1.0MPa and a permeability coefficient of 5 × 10-9cm/s. Bentonite is a natural inorganic material that does not undergo aging reactions and has good durability; And it will not cause any adverse effects on the environment, which belongs to environmentally friendly materials

　　2. 4800g GCL sodium based bentonite pad has all the characteristics of geotextile materials, such as separation, reinforcement, protection, filtration, etc. It is easy to construct and not limited by the construction environment temperature. It can also be constructed below 0 ℃. During construction, simply lay the GCL waterproof blanket flat on the ground. When constructing on a facade or slope, fix it with nails and washers, and overlap it as required.

　　3. Easy to repair; Even after the waterproofing (seepage) construction is completed, if the waterproof layer is accidentally damaged, simply repairing the damaged part can restore the perfect waterproof performance as before.

　　4. The performance price ratio is relatively high, and it has a wide range of applications.

　　5. The width of the 4800g GCL sodium based bentonite pad product can reach 6 meters, which matches the specifications of international geotextiles (membranes) and greatly improves construction efficiency.

　　Characteristics of 4.8kgGCL Sodium Bentonite Waterproof Blanket

　　1. Compaction: Sodium based bentonite forms a high-density diaphragm under water pressure. When the thickness is about 3mm, its permeability is below α × 10-11m/sec, which is equivalent to 100 times the compactness of 30cm thick clay, and it has strong self water retention performance.

　　2. The waterproof performance of 4.8kgGCL sodium based bentonite waterproof blanket: Because sodium based bentonite is a natural inorganic material, even after a long time or changes in the surrounding environment, it will not undergo aging or corrosion, so the waterproof performance is long-lasting.

　　3. Easy construction and short construction period: Compared with other waterproof materials, the construction is relatively simple and does not require heating or pasting. Just use bentonite powder and nails, washers, etc. for connection and fixation. The connection of GCL, especially when it is connected to pipelines or building surroundings, is simpler than that of geomembrane, and the sealing at the joints is also easily guaranteed. No special inspection is required after construction, and if waterproof defects are found, they are also easy to repair.

　　4. Integration of waterproof materials and objects: Sodium based bentonite has 13-16 times the expansion capacity when reacting with water. Even if the concrete structure vibrates and settles, the bentonite in GCL can repair cracks on the concrete surface within 2mm.

　　5. Green and environmentally friendly: Bentonite is a natural inorganic material that is non-toxic to human health and has no significant impact on the environment. It has good environmental performance.
