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:HDPE construction process of HDPE geomembrane
A, The laying of HDPE geomembrane. 1. Corresponding qualified check and acceptance documents are needed before paving HDPE geomembrane. 2. Before cutting HDPE film, accurately measure its relavant size, and then cut according to reality. It is not suitable to cut according to icon size. It should be numbered by sheet and recorded in detail on the special form. 3. There should be minimum welding line during paving HDPE geomembrane. Save raw material as much as possible on the premise of quality assurance. At the same time, it is easy to ensure quality. 4. The lap width of seam among films is usually not smaller than 10cm. Make orientation of welding line parallel to maximum gradient, namely, arrange along the gradient direction. 5. The seaming length should be shortened at corner and deformed section. Except special requirements, gradient is over 1: Except special requirements, gradient is over 1: Except special requirements, gradient is over 1: Except special requirements, gradient is over 1:
Q:Geomembrane is how the construction
Geomembrane construction methods are as follows: 1, in the determination of the scope of laying. Laying the composite geomembrane according to the requirements before the laying of sand cushion on the roadbed, laying width according to the design requirements set; 2, laying when not allowed to fold, try to tighten. 3, laying composite geomembrane, the sand cushion layer surface is smooth, no hard protrusion, paved and filled with sand in time to avoid the sun for a long time before the direct 5, composite geomembrane spread, the timely filling of the filler, to be covered with light after the use of light compaction mechanical compaction, only when the composite geomembrane laying, horizontal lap and longitudinal lap length to meet the design requirements; 6, composite geomembrane according to the design requirements can be divided into longitudinal and transverse force in two forms, the laying of composite geomembrane before the understanding of the design of the composite geomembrane Intent, in strict accordance with the design requirements laying.
Q:What is the working principle of the electric heating film
The electric heating film Electric heater belongs to is a new generation electric heater, which uses full transparent high temperature electric heating film as the heating material. The hot air passage structure is adopted to enhance the heat transfer mode, and the heat starting will be faster, and the temperature of the air outlet is more than 100 in 3 minutes, but it will imeediately cool off.
Q:How to clean computer keyboard film?
1, As long as the material of laptop keyboard film is silica gel, the surface of which will be oxidized in the air, and the surface of the laptop can dissipate heat, accelerating aging. When feeling sticky, the surface sticks a lot of dust, which means this keyboard protective film can not be used, so it doesn't need to be washed. 2, There is no need to use anything during washing, only need to swing in clean water for a few times, or washed in tap water and then tiled on clean and smooth surface to be naturally dried.
Q:The pool of the soil, the loss and the number of lap
This can discuss with the construction staff to decide how many centimeters,
Q:how to use the wall poster transfer membrane?
Instructions: 1. The transfer film products are suitable for the latex painted wall and other smooth, clean surface. 2. please carefully transfer the film joint pattern from the end of paper peeled off. 3. choosing the location to paste, using scratch cards to hang around to smooth out air bubbles between wall stickers and wall. 4. Remove the transfer membrane, gently tear the membrane and readjust the membrane if it is pushed and runned.
Q:What is the type of film thickness gauge
1. Ultrasonic thickness gauge Hong Kong Teichman TM1402. Taiwan Baker Royce paint film thickness gauge BK-8113A film thickness of iron-based coating thickness gauge 3. Lanteri coating thickness CM8822 non iron-based coating thickness gauge 4.LYT -2008 using magnetism thickness measurement method
Q:How is the power amplifier tone quality of thick membrane?
The tone quality of thich membrane power amplifier I have used is not so good, but it is ok if you don't have high demand for tone quality.
Q:Can composite geo-membrane be used for roof leaks?
No, usually we use SBS for roof waterproof. Composite geo-membrane is often used on the road and bridge projects.
Q:can RO membrane film be used to water purifier?
Ro film isnot suitable for water purifier, mainly because it is soft water. Oh, it is not good to health.
