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.

Geotextiles are fabrics made by weaving. Geomembranes are made by method of bonding impermeable membranes with geotextiles.
Personal feeling or I think that electric oil is better, safe.
Mobile phone tempered glass has the advantages of high-strength scratch-resistant. falling broken-resistant, ultrathin. and almost having no feeling when pasting on the phone . Glass surface has had special treatment, feel more smooth, and the operation is more fluent. Safety. Simple to install the glass membrane using electrostatic bonding mode, anyone can easily install, and it will not produce bubbles. Recycled, it can be reused for many times, and it will not leave marks on your phone. Screen transmittance is up to 98%. it can prevent the electron wave effects on human health. It does not affect the mobile phone sets and other mobile phone parts. nanometer-glass membrane has the technology of AGC glass reinforced HARVES HARVES nanometer technology through international nano-coating technology, using high-density nanoscale hydrophobic oleophobic coating and it can obtain ultra-lubricating function, so that the fingerprint traces of oil can not be left in the stick membrane surface, and it can reach the anti-fingerprint oil pollution-resistant effect. AGC glass reinforced technology it uses the imported AGC glass material, on the original proportions, spending on strengthening hardness treatment staggering 9H hardness. in the long term, it can effectively prevent stick membrane scratches, and has a high light transmittance. Ultra lubrication, making fingerprint traces of oil not be left in the stick membrane surface, and having the anti-fingerprint anti-oil pollution effect. AG glass Ultra-high transmittance glass plus HARVES nano-coating to improve the level of the transmitted light, the ultimate 94% transmittance, restore true color screen, greatly enhancing the definition of the screen, give the user a high-definition visual experience. , anti-explosion technology MAS glass film contains a special plastic material, it has made steel processing, and more secure when using it. the function of auto attachment

In general, it should not be cut according to graphic size. Shorten joint length and strain as far as possible. After geomembrane pavement, the lap?width between films should be not less than 10 cm. 4. Usually set at a corner and abnormal section. 6, arrange along the gradient direction and avoid accidental damage to membrane when the temperature is low. Lap width between membranes is generally not less than 10 cm. You should measure the accurate relative size. Do not weld as far as possible during geomembrane pavement . In addition to the special requirements, Do not walk on the membrane or carry on the membrane.
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
Firstly, look at the design and colour. In order to identify whether the household colourful film is good or bad, you should first check whether the color is even, whether there is chromatism and bleeding. Usually a pattern is better when the pattern is more clear. In the next step, you should look at the tenderness, which is mainly for non-woven fabrics and wall coverings, etc. You have to look at both sides. Usually the quality is better if density of the surface wove is higher. Secondly, touch it and feel its toughness. Some people think that household colourful film is better when it is thicker, which is a misunderstanding. The quality is related to the quality of paper, production technique and toughness, and thickness, and not directly related to the thickness. When you identify the wallpaper by hand, you should touch it and feel and toughness, particularly for flocking wallpapers. They are most likely to feel the difference between good and bad. Usually the quality and toughness is better when it is softer. But when domestic and imported products that are made of the same material are compared, the imported ones will be relatively thick and of higher density. Third, smell it. Inferior household colourful film has bad smell. In addition, the real environmentally friendly film has no smell, but if it is made of inferior materials, it will have a pungent smell. You can smell it when coming close to it. Fourly wipe it. Wear-resisting and soiling-resisting should be tested. It is recommended that consumers draw some lines on the paper and the wipe them in the purchase process. Generally high quality colorul decoration film can easily be cleaned even if the surface is bumpy, but if it is of low quality, it is easy to be scraped or not easy to be cleaned.
This is non-toxic. Generally, fish pond, shrimp pool, reservoir paving impermeable geomembrane construction would use geomembrane special adhesive, because it is cheaper than welding, convenient and simple.
