Bentonite has the property of swelling in contact with water

Bentonite waterproof blanket is a kind of geosynthetic material, specially used in artificial lake landscape, landfill, underground garage, roof garden, swimming pool, oil depot and chemical plant. It is made of wholesale bentonite geosynthetic clay liner with high swelling properties and filled between 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 a uniform high-density gel-like waterproof layer on the cushion, effectively preventing water leakage. According to its chemical composition, the mineralogical name of bentonite is montmorillonite. Natural bentonite is mainly divided into sodium and calcium. Bentonite has the property of swelling in contact with water Bentonite has the property of swelling in contact with water. When high quality GCL geosynthetic clay liner calcium swells, its swelling amount is only about 3 times its own volume, while sodium-based bentonite absorbs 5 times its own weight when exposed to water, and its volume swells 15-17 times. Bentonite is locked between the two layers of geosynthetics to protect and strengthen GCL, which has a certain overall shear strength. Sodium bentonite forms a high-density membrane under water pressure. When the thickness is about 3 mm, its water permeability is less than 10×11 m/s, which is equivalent to 100 times the compactness of 30 cm thick clay. It has a strong self-power. Because sodium bentonite is a natural inorganic material, it will not age or corrode even after a long time or changes in the surrounding environment, so its waterproof performance is durable. Bentonite is a kind of natural inorganic material, which is harmless to human body and has no special impact on the environment. It has good environmental performance. However, the material of GCL geosynthetic clay liner manufacturers waterproof blanket is heavier and should be transported and laid with a shovel and waterproof blanket spreader. When installing the bentonite waterproof blanket, the outdoor temperature shall not be lower than 0℃ or higher than 40℃. # 5. All exposed edges of the bentonite waterproof blanket must be immediately squeezed with sandbags or other heavy objects to prevent the bentonite waterproof blanket from being blown away by the wind or being pulled out of the surrounding fixed ditch. The bentonite waterproof blanket cannot be used in windy weather to prevent it from being blown away.

Geomembrane is a kind of high molecular polymer plastic film

I believe there are still many friends who do not understand our composite geomembrane! What is our composite high quality aquaculture geomembrane? What is the unit price of composite geomembrane? Now let us bring the geomembrane manufacturer to talk about our composite geomembrane. What is composite geomembrane? What is the unit price of composite geomembrane? The environmental geomembrane manufacturers uses plastic film as an impermeable substrate and non-woven fabric. Its impermeability mainly depends on the impermeability of the plastic film. At present, the plastic films used for anti-seepage at home and abroad are mainly polyvinyl chloride (PVC) and polyethylene (polyethylene), which are flexible polymer chemical materials with small specific gravity, strong ductility and strong deformation adaptability. Corrosion resistance, low temperature resistance, and good frost resistance. The main mechanism is to isolate the leakage channel of the earth dam with the impermeability of the plastic film, and to withstand the water pressure with greater tensile strength and elongation to adapt to the deformation of the dam. Non-woven fabric is also a kind of short polymer chemical material. Through needle punching or thermal bonding, it has high tensile strength and ductility. When combined with plastic film, it not only increases the tensile strength and puncture resistance of the plastic film, but also increases the friction coefficient of the contact surface due to the rough surface of the non-woven fabric, which is beneficial to the stability of the composite geomembrane and the protective layer. At the same time, they have good corrosion resistance to bacteria and chemicals, and are not afraid of acids, alkalis and salts. The main mechanism of the high quality LDPE geomembrane construction site is to isolate the leakage passage of the earth dam with the impermeability of the plastic film, and to withstand the water pressure with its larger tensile strength and elongation to adapt to the deformation of the dam. Non-woven fabric is also a kind of short polymer chemical material.

Three points to note when buying geotextiles

How popular is geotextile now? Geotextiles are not only used for building road projects, but also a large number of water conservancy projects. Geotextiles may continue to enter other industries and fields in the future. How to choose the specifications of geotextile Although high quality polyester nonwoven geotextile are widely used, in order to meet the needs of different projects, the specifications of geotextiles are also increasing. This has led many people who do not understand to choose geotextiles, such as buying clothes without knowing their own codes and not allowing them to test. So in actual engineering applications, how should the specifications of high quality polypropylene nonwoven geotextile be selected? If you really don’t understand or don’t understand, please pay attention to two points: either follow the designer’s requirements or follow the on-site technician’s suggestions. These two points are a safer method. Of course, if you can only come by yourself, please follow two principles, that is, the thickness should not be thin and the width should not be narrow. If you choose randomly, the specifications of the geotextile may not meet the standard or meet the requirements of the actual project. Forcible use of geotextiles will cause certain difficulties for construction personnel and affect the actual construction progress of the project. The consequences are not easy to bear. Three points to note when buying geotextiles When buying geotextiles, apart from specifications, we should not be careless in other aspects. There are three main points to note. 1. When choosing geotextiles, if you can choose thick filament nonwoven geotextile for sale, do not use thin geotextiles, because compared with thin geotextiles, thick geotextiles not only have good tensile strength and compression resistance, but also It can also play a good barrier and protection role during use. 2. Choose domestic geotextiles as much as possible, because non-standard geotextiles are inferior to domestic geotextiles in all aspects, especially in terms of strength, puncture resistance and durability. 3. Try to choose a geotextile with sufficient width, because this can reduce the number of welding or stitching of the geotextile during the construction process and greatly improve the construction progress.

Geomembrane should have good mechanical properties

The selection of geomembrane should be comprehensively considered in terms of engineering application, economy, construction process characteristics and material properties. The first thing to consider is whether the permeability and quality meet the requirements. Secondly, the high quality HDPE geomembrane should have good mechanical properties, such as penetration resistance, puncture resistance and tensile strength, to resist damage encountered during transportation and construction. Of course, in the construction process, we should also pay attention to protect it from damage. In addition to the above aspects, we should also consider its durability and thickness. Geomembrane should have good mechanical properties At present, there are generally three standards for anti-seepage high quality aquaculture geomembrane, namely GB/T 17643-2011 GH-1, GB/T 17643-2011 GH-2 and the urban construction standard CJ/T234-2006 produced by brand new materials. Most geomembrane manufacturers are concerned. How to choose the thickness of geomembrane in anti-seepage project? There is no doubt that the thicker the geomembrane, the better, but at the same time the cost will increase and become thinner. Although the cost can be reduced, it cannot meet the needs of the project. Therefore, choosing a suitable thickness of geomembrane can not only meet engineering needs, but also achieve the purpose of reducing costs. The choice of thickness should be cautious and tailored according to the engineering requirements of the geomembrane. The thickness of the environmental geomembrane manufacturers is generally not less than 0.5 mm. For some important projects with higher requirements, it should be thickened appropriately. During the actual operation of the project, it is necessary to entrust the relevant testing center to test the materials to prove whether the quality of the geomembrane produced by the manufacturer is reliable, and to provide a basis for selecting safe, reliable and economical materials. The application environment of geomembrane is buried in the ground all year round, so it is required to have good anti-aging and anti-decomposition ability, and can effectively resist the puncture of plant roots. For geomembrane working in complex water environment, it should also have good acid and alkali resistance. Through the above description, you should understand the selection method of geomembrane thickness, and pay attention to avoid uncivilized construction in construction. If used in a complex environment, you can choose a composite geomembrane with geotextiles on both sides to prevent sharp objects from damaging and damaging the membrane material. There are many kinds of geomembranes. Only by choosing a suitable geomembrane can we achieve better anti-seepage effect, increase the service life of the geomembrane, and reduce the construction and maintenance costs of water conservancy projects.
