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.


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

  • good temperature properties

  • great chemical stability

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:how to construct composite geo-membrane and two cloths film one film?
Construction technology of two cloths one membrane, and the connective way of two cloth one membrane edges. ① membrane and membrane's welding, non-woven cloth seams, seams film is departed with the cloth, it can't be synchronizely stressed, seam strength is 20-40% of the base materials, the connective way of two cloths film one film edges. ① membrane and membrane's welding, non-woven fabrics' seams, seam film is departed from the cloth, and can't stand synchronized force.
Q:Is black HDPE geomembrane eco-friendly?
Raw material of HDPE geomembrane is HDPE particles, adding carbon black to become black. It is buried underground to prevent hazardous liquid leakage. So HDPE geomembrane can be considered as environmentally friendly.
Q:where can i buy cheap geomembrane?
Currently. Currently, good frost resistance performance,plastic film applied for seepage-proof at home and abroad, two films a cloth is in favor of the stability of protective layer and composite geo-membrane; vinyl copolymer (EVA). Corrosion resistance; and non-woven staple fiber is macromolecule staple fibre chemical material, mainly including polyvinyl chloride (PVC), polyethylene (PE), it's produced by the manufacturer according to individual requirements, low temperature resistance, various product specifications, there are many domestic geomembrane production manufacturers, ethylene & # 47 through needle stick or hot sticking forming, which is flexible material polymer chemistry, and because the rough non-woven surface, two cloth one film. Meanwhile, the base, etc., has high tensile strength and elongation, smaller proportion, strong extension, not afraid of acid, high adaptability to the deformation, it can be also requested by the user according to their actual situation, and it can not only increase plastic film tensile strength and puncture resistance. The main mechanism is cutting off earth leakage passage with the imperviousness of plastic film, they have good corrosion resistance for bacteria and chemical function and has good chemical resistance, its tensile strength and elongation can withstand water pressure and adapt to dam deformation ; after it is combined with plastic film, increasing the friction coefficient of the contact surface; m2, etc., salt erosion, a cloth membrane, two cloth membrane and two cloth more and more film. Models include 200g & # 47 geomembrane takes plastic film as seepage-proof substrate, its seepage-proof performance depends on seepage-proof properties of plastic film and soil engineering impermeable material composed by non-woven cloth.
Q:What is the difference between nonwovens and geomembranes in hydraulic engineering?
Nonwovens is a cloth, geomembrane similar to the greenhouse film.
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:The design of geomembrane thickness of 0.5, you must be up to 0.5.
To perform in accordance with design requirements like design thickness of 0.5mm geomembrane geomembrane design requirements to be procured 0.5mm geomembrane standard GB / T17643-2011 standards or CJ / T234-2006 standards in accordance with the requirements of the standard deviation as the thickness of 0.5mm geomembrane thickness limit deviation -10%, or thin spots can be lower than the average thickness of 0.45mm design requirements geomembrane standard deviation 0 American standard GRI GM-13 standard 0.5mm geomembrane allows less than 0.5mm thickness of 0.5mm site must be
Q:Is electrothermal film a big consumer of electricity?
The electrothermal film floor-heating system is intelligent. The film will automatically stop heating when the temperature of the surface of floor reaches the set point and then remain in the state of heat preservation. Actually it works only several hours a day.
Q:What are the differences between the geomembrane and the anti-seepage film?
Composite geo-membrane(composite anti-seepage film) is divided into one cloth and one membrane and two cloths one film, the width of which is 4-6m, and weight is 200 - 1500g/square meters.It is characterized by high index of physical and mechanical properties comprising tensile, tear, bursting resistance, high strength, good extensibility, large modulus of deformation, acid and alkali resistance, corrosion resistance, aging resistance, as well as good impermeability. Additionally, it can meet the needs of seepage-proof, isolation, reinforcement, anti crack of irrigation, municipal administration, construction, transportation, subway, tunnels, and other needs of civil engineering. Because its selected high polymer materials and the manufacturing technique have been added antioxidant, it can be used in the non conventional temperature environment. It is commonly used in seepage prevention treatment of dam and drainage ditch, and anti fouling treatment of waste dump.
Q:What is the difference between cement pond lotus and geomembrane harvest?
Now with a good quality of the new material film, seepage is not good, the general use of geotechnical membrane to do high cost of impermeable cement
Q:What are the functions of the battery diaphragm?
The diaphragm of the battery mainly has two functions: 1. Insulating layer, can effectively prevent the contact of positive and negative electrodes to avoid internal short circuit 2. Semi permeable layer, it mainly exists in liquid batteries like the lithium ion battery, which can hold back molecules of relatively large volume and only allow charged ions of small volume to get through, improving the concentration difference in the vicinity of the positive and negative electrodes and in favor of the ion diffusion, so as to improve the storage efficiency of the battery.
