Seepage principle mineralogical name of bentonite montmorillonite, bentonite according to the chemical composition of natural sodium and calcium are divided into two categories based. Bentonite has a water swelling characteristics of customized isolation waterproof blanket, when calcium bentonite expands, its expansion is only about three times its own volume, and five times its own weight of water adsorbed sodium bentonite water, swelling to the original 15- more than 17 times, the sodium bentonite locked in between two layers of geosynthetic materials for protection and strengthening of the role of the GCL has a certain overall shear strength. Features 1. compactness: sodium bentonite formed under a state of high density pressure isolation diaphragm best waterproof blanket, when the thickness of about 3mm, its permeability of 5 × 10ˉ11m / s or less isolated waterproof blanket, which is equivalent to 100 times the density of 30cm thickness of clay, has a strong self-protection water performance. 2. permanent waterproof performance: Department of Natural sodium bentonite as inorganic materials, even after a very long period of time or the surrounding environment changes, aging or corrosion quality waterproof blanket isolation does not occur, and therefore durable waterproof performance. 3. Construction is simple: other waterproof materials, the construction is relatively simple, does not require heating and paste. Just bentonite powder and nails, washers, etc. are connected and fixed. After the construction does not require special inspection, if found defective water is also easy maintenance. GCL is available in waterproof material shortest construction period. The temperature is not affected: in cold weather conditions are not brittle fracture. 5. Integration of waterproof materials and objects: sodium bentonite water, with 20 to 28-fold expansion of capacity, even if the concrete structure to vibrate and settlement, GCL bentonite can repair cracks within 2mm of the concrete surface. 6. Green: Bentonite is a natural inorganic material, no particular impact on the environment, with good environmental performance. GCL price of the product provides technical indicators: No. Item Unit test and inspection requirements for a quality bentonite expansion coefficient ml / 2g ≥24 2 GCL unit area g / m2 ≥5000 3 GCL longitudinal fracture strength KN / m ≥10 4 GCL transverse rupture strength KN / m ≥10 5 GCL longitudinal elongation at break% ≥10 6 GCL transverse elongation at break% ≥6 7 GCL vertical permeability coefficient cm / s ≤5 × 10-9 8 GCL anti-puncture strength N ≥400 9 GCL peel strength N / 10cm ≥65 10 GCL anti hydrostatic test 0.3MPa 30min no leakage waterproof blanket and objects integrated by the majority of consumers: sodium bentonite water, with 20-28 times expansion capabilities, even if the concrete structure to vibrate and settlement, GCL bentonite can repair the concrete surface cracks within 2mm.
