Detailed Product Description: | Zhengzhou waterproof blanket to recommend a good quality waterproof blanket Tel: 13639450809 Chen GCL (GCL) GCL is a cross between the first volume of CCL (site of compacted clay impermeable liner) and a high molecular material - - An impermeable geomembrane liner between. Important use in environmental engineering burned material landfill, open reservoirs, public foundation approach to building and other projects, for the seal, cut off, anti-leakage problem, the result is good, strong anti-crush. Mineralogical title bentonite montmorillonite principle, according to the chemical composition of natural bentonite important sodium and calcium into two categories based. Bentonite with water features shrink, while the general calcium bentonite contraction, the contraction was only about three times its own volume; while sodium bentonite contraction of about l5 times its own volume, and can draw six times its own weight of water, high density bentonite colloids shrink as promised posed with exclusion of water functions. Manipulation of this performance, people do use sodium bentonite waterproofing material. In order to facilitate the construction and transport, will be locked in bentonite layers of geotextile material decomposition center, shelter and reinforcement from probation, so GCL groups have certainly shear strength. GCL features 1. compactness: sodium bentonite under pressure conditions constitute a high-density cross barriers, a thickness of about three sisters, its permeability for α × 10-11m / sec below, equivalent to 100 times the 30cm The thickness of the density of clay, with a strong self-protection water performance. 2. With timeless waterproof function: As the Department of natural sodium bentonite organic material, even if Britain or four weeks at the end of a very long-term changes in the environment, it does not produce signs of aging or decay, is a long-term water-proof function. 3. The construction is simple, short construction period: and waterproof material than the rest of the force, comparable to the relatively simple construction, unnecessary heating and paste. As long as bentonite powder and nails, washers, etc. contiguous and secure. Also after the construction of unnecessary special examination, if the invention is also easy Peixiu waterproof shortcomings. GCL is a waterproof material existing in the shortest construction period. The temperature is not affected: in cold weather is not the premise of brittle fracture. 5. waterproof material and tool integration: sodium bentonite and water reaction, with 13-16 times the contraction ability, even if the layout of objects produce concrete touch and settlement, GCL bentonite can repair the concrete within two sisters profiles cracks. 6. Green: Bentonite is a natural organic material, non-toxic and harmful to the environment does not affect the special addition, with excellent environmental performance. GCL GCL important for the good of the soil carpenter Cheng, hydraulic engineering, environmental engineering or impermeable seal, such as channels, reservoirs, dams seepage plan, foundation garbage dump, the perimeter roof seal program, artificial rivers, lakes The leak-proof plan and so on. Most can Lingding use, but also with compacted clay layer, or a combination of geomembrane use. When the plan to allow the choice of clay, asphalt, concrete, geomembrane, GCL as a sealing layer, GCL cooperate more with force. Compare with compacted clay, GCL good table of important nowadays: small size, light weight, simple construction, and have a higher shear strength. And geomembrane match, good sex is now important table GCL following aspects: (1) GCL flexible, and can better adapt to uneven settlement; (2) the thickness of the layer of bentonite GCL growth after absorbing several times, and wrapped in geotextile by asylum, is not easy to be broken or punctured top effected, laying garden premise request is lower than the geomembrane. When adopting the average cage mulch, general request a maximum particle size not over 32 sister. (3) GCL contiguous, especially when the GCL with construction material around the pipe or adjacent to, than geomembrane concise, and sealing the seams are prone to guarantee. (4) GCL have better than geomembrane interface friction characteristics. (5) GCL easy to transport and placement, its performance will not be impervious repeated freeze-thaw cycle of wet and rather low, and probably also because of leaking drops of bentonite migration and self-healing. GCL skills nominal target detection test nothing, skills, goals contraction coefficient ASTMD5890≥24mL / 2g fluid consumption ASTMD5891≤18mL unit area bentonite quality ASTMD5993≥4.8kg / m2 ASTMD4632≥400N tensile peel strength ASTMD4632≥65N instructions flow ASTMD5887≤1 × 10- 8m3 / m2 / sec permeability ASTMD5887≤5 × 10-9cm / sec after the invasion tensile ASTMD5321≥24kPatypical GCL is a new type of geotextile material decomposition throughout for municipal, highway, railway, water conservancy, environmental protection, and industry construction and civil construction of public water seepage. |
