What is geomembrane?

Geomembrane takes plastic film as the anti-seepage base material, and is compounded with non-woven fabric. The anti-seepage performance of new material geomembrane mainly depends on the anti-seepage performance of plastic film. Plastic films for anti-seepage applications at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), EVA (ethylene/vinyl acetate copolymer). In tunnel applications, ECB (ethylene vinyl acetate modified asphalt blend geomembrane) is designed and used. They are polymer chemical flexible materials with small proportion, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance and good frost resistance.

Characteristics of geomembrane

The composite geomembrane is made of plastic film as the anti-seepage base material and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. Plastic films used for seepage prevention at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), ethylene/vinyl acetate copolymer (EVA), which are polymer chemical flexible materials with small proportion, strong extensibility, high deformation adaptability, corrosion resistance, low temperature resistance and good frost resistance.

The service life of composite geomembrane is mainly determined by whether the plastic film has lost its anti-seepage and water separation function. According to the national standard of the Soviet Union, the polyethylene film with a thickness of 0.2m and stabilizer for hydraulic engineering can work for 40 to 50 years in clean water and 30 to 40 years in sewage. Therefore, the service life of composite geomembrane is sufficient to meet the service life of dam anti-seepage requirements.

Scope of application of geomembrane

Zhoutou reservoir dam was originally a core dam, but due to dam collapse, the upper part of the core wall was disjointed. In order to solve the problem of seepage prevention in the upper part, an anti-seepage inclined wall was added. According to the safety demonstration and analysis of Zhoutou reservoir dam, in order to solve the problem of weak seepage surface and dam foundation leakage caused by multiple landslides of the dam, seepage prevention bodies such as bedrock curtain grouting, contact surface grouting, backfill curtain of grab sleeve well and high-pressure jet grouting seepage prevention board wall are adopted in vertical seepage prevention. The upper inclined wall is covered with composite geomembrane for seepage prevention. The lower part is connected with the vertical cut-off wall and the upper part is 358.0m high.

Performance characteristics of HDPE geomembrane

4. HDPE geomembrane has a very high tensile strength, so that it has a very high tensile strength to meet the needs of high standard engineering projects;

5. HDPE geomembrane has strong weather resistance, strong anti-aging performance, and can be used naked for a long time to maintain the original performance;

6. Overall performance of HDPE geomembrane. HDPE geomembrane has strong tensile strength and elongation at break, enabling it to be used under various adverse geological and climatic conditions. Strong strain force to adapt to geological uneven settlement;

7. HDPE geomembrane is made of high-quality original plastic and carbon black particles without any preservatives. HDPE has been used in China to replace PVC as the raw material of food packaging bags and fresh-keeping films.

Q:The difference between geomembrane and the geotextile in construction technology?
Q:The working principle of the water film dust collector?
Its working principle is: Dust containing gas by simplified lower tangential rotation along the introduction, rise, dust particles by centrifugal force and is separated into the inner wall of the barrel body, the inner wall of the adsorbed water layer flow, with the water in the end part of the cone, the dust discharge port of unloading. The water film layer is formed by arranging a plurality of nozzles arranged on the upper part of the cylinder, and cutting the water along the tangential direction to the wall of the device. In this way, the inner wall of the cylinder is always covered with a layer of a thin water film which flows downward, so as to achieve the purpose of improving the dust removal effect.
Q:How to purchase geomembrane?
warp-wise tearing strength, warp-wise elongation at break, puncturing strength, broadwise breaking strength, film material thickness, CBR bursting strength, unit area quality inspection, permeability coefficient, broadwise tearing strength, broadwise elongation at break, warp-wise breaking strength.
Q:Is the mobile phone laminator useful
Personal feel very good, that's all depends on you. The toughened glass film is very good but also expensive. If you do not like the fingerprint on the screen, then toughened glass film is a good choice. Tempered glass film is wear-resistance, it can protect your phone, and it is very convenient to paste up. Girls can do it by yourself, the frosted glass film needs a little bit technology. The 20 yuan tempered film in the Taobao, you brought it use as the normal HD film, a year for a properly yourself is not as film black, most three membrane can to the phone used replacement, if common HD film, no protective flip cover, often and key put together, more than three months will need to change.

Q:How to remove the protective film of the guard against theft?
There are many methods: 1: The area is not large and you can use banana water to soak it and then clean it with a cleaning ball. 2: It can be removed with cleaning agents (bottled called A1) used in the textile industry.I have tried. It is very good. 3: To add some sulfuric acid into the water, otherwise it will be corroded and then rub with the cleaning ball. 4: To heat it with the electric hair drier, or with a wooden shovel, plastic marks can be used to wipe off the solvent oil
Q:Which one is better, electric heating film and carbon crystal?
First of all the inside of electric heat mold is all wire. We are taught in high school physics that electromagnetic radiation is powerful if there are a lot of electric circle. Can you feel safe on thinking that your house is surrounded by electromagnetic radiation,
Q:Does the electrothermal film consume a large amount of electricity?
Power consumption of it is not that much, it is better than warmer, because i bought it recently so the quality is very good, temporarily there is no problems.
Q:whether the sound insulation membrane of windows and door is useful?
Doors and windows soundproof membrane effect is still very good, under normal circumstances, a qualified good installment doors and windows soundproofed reasonable film thickness is sufficient to achieve a compliant body sound insulation, windows and doors sound insulation membrane is to prevent noise intrusion, you can add a layer of tight sound insulation film or a relatively strong absorption of cotton close to the transport routes. In order to prevent TV, stereo, piano disturbing your neighbors, you can add ultra-thin glass absorption cotton in television, audio background wall, the effect is very good.
