Product Description:

Description of self adhesive hdpe geomembrane sheet: 


    HDPE is a non polar thermoplastic plastic with high crystallinity and perfect electrical properties,especially the high insulation dielectric strengh.This polymer is non-hygroscopic which can be used to packing with good waterproof steam.HDPE with Middle to high molecure weight have good impact resistance at normal temperature even in the zero 40 degree Celisius.

 

     Its surface won't wrinkle and is weather resistant.Because it is durable it has a long service life and acts as a flexible hinge that won't break.Our HDPE sheets can be customes produce to match specific colors,thickness,size and finish.



Advantages of self adhesive hdpe geomembrane sheet:

  • high insulation dielectric strength

  • perfect impact resistance

  • good heat /cold endurance

  • no toxic

  • excellent chemical resistance

  • low water absorption

FAQ
1Why use HDPE sheet?                                                                                                                                 

HDPE Sheet has an almost waxy feel to it and is pretty good at being a low friction wear strip material and is used probably more than any other plastic as a wear strip on conveyors or production lines of huge companies.

Q:Which is better between electric hot plate and electrothermal film?
It depends on actual situation, which can not be directly determined which one is good. The electrothermal film is a kind of exothermic material made of special conductive macromolecule material matched with metal current-carrying strip, hot melted between the insulating film bodies, which will produce heat after being electrified Mainly used for heating element. The electric hot plate is equippment taking electric heating alloy wire as heating material, and mica soft board as insulating material, and wrapping thin metal plate (aluminum plate, stainless steel plate, etc) in the surface for heating. Typical applications like electric hot water bottles. Casting metal tubular electric heating element in aluminum plate/aluminum plate or welding or inlaying on the aluminum plate/aluminum plate to form electrical heating plate of all shapes. Typical application like electric cookers, electric irons, electric coffee makers, etc.. ! ~
Q:Geomembrane and geotextile construction scheme
Shallow water lotus root planting technology has become the most water and fertilizer saving method after a few years of development. In order to break through the restricting bottleneck, cropping pattern with the best economic benefits, the most convenient management. Especially suitable for water-deficient area!
Q:How to choose and buy the laminating machine.
Small automatic laminating machine is due to the heat roller lamination, upper and lower into the membrane, increasing the heating time of the predeposited membrane, and heat balance, so cover out of the membrane, and smooth, bright, membrane effect and high grade film coating machines. Due to the heating power of this kind of small laminating machine is only 500-1000W. Although the temperature is adjustable but the speed is fixed. It can be 1 meter from the film every minute. At present, the market prospect of this type of film laminating machine is very good, a lot of the original is only their own customers to start with this kind of film laminating machine sales, and sales volumn are good.
Q:What is the mechanism of vacuum tube coating?
Evaporation coating is to vaporize a substance by heating so that it can deposit on a solid surface. First proposed in 1857 by M. Faraday, this approach has become one of the common coating technologies in modern times. The structure of the evaporation coating device is shown in figure 1. Vaporized material such as metal and compound are placed in a crucible or hung on the hot wire as the evaporation source and the workpiece to be coated, such as metals, ceramics and plastics are placed in front of the crucible. After the system is vacuumized, the crucible should be heated so that the material therein evaporates. Atoms or molecules of the evaporated material is deposited on the substrate surface in condensation mode. The thickness of the film ranges from several hundred angstroms to several microns. Thickness depends on the evaporation rate and time (or inventory) of the evaporation source and is related to the distance between the source and the substrate. For large-area coating, the method of rotating the substrate or increasing evaporation source is often used to ensure that the thickness of the film is even. Distance from the evaporation source to the substrate should be less than the mean free path of vapor molecules of residual gas to prevent vapor molecules from colliding with residual gas thus causing chemical action. The average kinetic energy of the vapor molecules is about 0.1 to 0.2 eV.
Q:Which one should be used for p lanting lotus, woven geomembraneor or blow molding geomembrane?
Its anti-seepage effect is not as good as composite geomembrane and the cost of it is much higher than the composite geo-membrane. There are woven geotextile and composite woven geomembrane. Woven geotextile is not seepage-proof. Currently the seepage-proof geomembrane for planting lotus is generally blow molding geomembrane or composite geo-membrane.Composite woven geomembrane is seepage-proof. There isn't a product named wowen geomembrane.
Q:how to remove the oxidation of the packaging film of aluminium alloy door and window by the sunlight?
Try using a solution of diluted paint, as well as alcohol and acetone solution (because they are all organic solvents). But I think that the kind of diluted paint would be easy to use. Here we call it releasing the receiving water, it may also be called lacquer thinner.
Q:What's the technical standards of geomembrane?
The national standards of geomembrane is GB / T17642-2008. Geomembrane 1. longitudinal and transverse breaking strength. 2. Vertical and horizontal elongation corresponding to the standard strength. 3. CBR bursting strength 4. 5 vertical and horizontal tearing strength. 5, hydrostatic pressure resistance. 6. peel strength. 7. vertical penetration index. 8, width deviation, the above technical requirements that confirm to the national standard are national standard geomembrane.
Q:How to remove the oil film in the fish tank?
You can use a tissue to adsorb it. The water surface of the tank is exposed to the air, so sometimes there will be oil film on it. The film will influence the oxygen content of the water. It is also recommended that you do not use mineral water to breed fish, especially for raising the paracheirodon innesi. This kind of fish like to live in the faintly acid soft waterwith the temperature of 22-24 degrees, pH value of 6.4-6.8 and hardness of 4-8.
Q:What are the differences between PE geomembrane and PVC geomembrane?
PE geomembrane is made by processing ethylene raw material. PVC geomembrane is made by processing polyvinyl chloride raw material. Domestic projects nowadays all use the former one which is environmentally friendly, non-toxic, anti-aging, corrosion resistance, and strict national standards have been developed.
Q:The features of HDPE geomembrane
As a new material, geomembrane has excellent anti-seepage effect, corrosion resistance and chemical stability. And it can process features and functionality according to the actual project needs. Geomembrane has been widely used in water conservancy embankment dam , reservoir seepage. At the same time, it has ben widely used as seepage-proof, anti-corrosion, leakage-proof and non-hygroscopic material in channel, impounding reservoir, cesspit, swimming pool, house building, underground structure, wasteyard, environmental engineering, etc.
