Heilongjiang 300g anti-seepage membrane - Two fabrics and one membrane 300g

Description :

　　Heilongjiang 300g anti-seepage membrane - Two fabrics and one membrane 300g.

　　300g of Hunan geomembrane_SN2/PE composite geomembrane.

　　The anti-seepage membrane produced by Shandong Dexuda Geotechnical Materials Co., Ltd., also known as two fabrics and one membrane, is divided into one fabric and one membrane, two fabrics and one membrane, and three fabrics and two membranes according to the product structure. This product is a geotechnical anti-seepage material composed of plastic film as the anti-seepage substrate and non-woven fabric composite. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. At present, the plastic films used for anti-seepage applications mainly include polyethylene (PVC) and polyethylene (PE), which are high molecular weight chemical flexible materials with low specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance. The thickness of the film is generally 0.30-2.00mm.

　　Jiangsu 300g impermeable geotextile with two fabrics and one film 300g.

　　Heilongjiang 300g anti-seepage membrane - Two fabrics and one membrane 300g.

　　The main mechanism is to use the impermeability of plastic film to block the leakage channel of the earth dam, and to withstand water pressure and adapt to dam deformation with its high tensile strength and elongation. Non woven fabric is also a type of polymer fiber chemical material, which is formed by needle punching or thermal bonding and has high tensile strength and extensibility. At present, the non-woven fabrics mainly used in composite include: polyester short fiber needle punched geotextile, polyester long fiber spun clay geotextile, flat fiber plastic woven fabric, etc. After being 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 for the stability of the composite geomembrane and protective layer. At the same time, they have good corrosion resistance to bacteria and chemical reactions, and are not afraid of acid, alkali, or salt erosion.

　　3、 The purpose and function of anti-seepage membrane:

　　Widely used in many fields such as water conservancy, dams, tunnels, road construction, airports, etc., it mainly plays a role in waterproofing, anti-seepage, protection, reinforcement, leakage prevention, isolation, etc. in engineering. 300g SN2/PVC two cloth and one film in Sichuan, 300g polyethylene geomembrane.

　　300g of geotextile with one cloth and one film in Hunan province, and 300g of impermeable geotextile.

　　4、 Construction requirements for two fabrics and one film:

　　1. The use should be buried, and the covering thickness should not be less than 30cm

　　2. The entire anti-seepage system is composed of a cushion layer, anti-seepage layer, transition layer, and protective layer.

　　3. The soil should be solid, avoiding uneven settlement, cracks, and removing grass and tree roots within the anti-seepage range. Lay a protective layer of sand or clay with small particle size on the contact surface with the membrane. Zhejiang 300g PE composite geotextile_SN2/PE two cloth and one film 300g.

　　4. When laying, do not pull the geomembrane too tightly. It is better to embed the soil at both ends in a corrugated shape, especially when anchoring with rigid materials, leaving a certain amount of expansion and contraction.

　　5. During construction, stones and heavy objects should be avoided from directly hitting the geomembrane. The construction should be carried out while laying the membrane and covering the protective layer.
