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.


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:What exactly is the geomembrane? What are the applications?
At the same time, alkali and salt corrosion, long service life; and non-woven fabric is also a kind of high-molecule short fiber chemical material. Geomembrane construction site its main mechanism is to use imperviousness of plastic film to cut off earth dam leakage passage, not only increases the tensile strength and anti-puncture ability of plastic film. They have good corrosion resistance to bacteria and chemical action, which is conducive to the stability of composite geomembrane and protective layer, with high tensile strength and extensibility, bearing the hydraulic pressure and adapting to dam deformation with its large tensile strength and ductility, increasing the friction coefficient of the contact surface. And due to the roughness of the non-woven surface, geomembrane construction site its main mechanism is to use imperviousness of plastic film to cut off earth dam leakage passage; and non-woven fabric is also a kind of high-molecule short fiber chemical material, bearing the hydraulic pressure and adapting to dam deformation with its large tensile strength and ductility, through needle punching or hot sticking forming, it is combined with plastic film, used in the dark place, not afraid of acid
Q:What is the principle of ceramic membrane ?
A layer of glaze will be formed in the process of firing .
Q:How to deal with oil slick on fish tank?
1. Using the oil slick processor to make the oil slick into the filter, and then using the filtering cotton in the filter to adsorb, at last decomposing bacteria by nitrobacterium. 2.Collect oil slick in the cup slowly and then dump it. 3. Use oil-absorbing sheet to absorb, put an oil-absorbing sheet at the opposite corner(oil-slick aggregated area) of water outlet to absorb oil slick. 4. Install trumpet funnel commingler to absorb oil slick, mix it with water, and it will be decomposed through absorption by filtering cotton. 5. Remove contamination in the filter. 6. Feeding fish which lives on oil such as highfin coralfish or black mollyack, which can reduce the film production.
Q:When can't PDHE impervious film be installed?
It can not be installed in winter for the low temperature will affect the effect of construction and welding.
Q:How to stick membrane on the cabinet?
1) Clean the surface of the cabinet. The 75%vol medicinal alcohol is recommended because it is easy to clean and dries rapidly. 2) Measure the size of the area where you want to stick membrane. 3) Tailor the membrane you bought according to the size. To avoid waste, a draft is recommended. 4) Stick the membrane from up to down gradually and check at all times to prevent the membrane from being slantways stuck. It is really a great trouble to deal with the membrane slantways stuck.
Q:What are the differences of pvc geomembrane and pe geomembrane?
PE geotechnical membrane is made rom polyethylene raw materials. PVC geotechnical membrane is made of polyvinyl chloride raw material. Domestic projects are now using the former which is environmental-friendly, non-toxic, anti-aging, corrosion resistance, and has developed strict national standards. The latter is rarely produced in China. PVC contains certain toxic chemicals, therefore, water conservancy and environmental protection project does not recommend the application of PVC geotechnical membrane, there does not seem to have the standard requirements of this product.
Q:What is the installation technology of soft membrane?
When installing the soft membrane, the first is to install the four angles of A, B, C, D, then the diagonal pull point installation, finally all installation. The installation sequence: 1. Before the entering of the soft film smallpox, the site must be electrified and without construction waste. 2. The deal with the bottom of the piamater ceiling should be fit for the installation conditions, such as the installation of the steel and so on; it must be cleaned. 3. All the installation of the lights must be according to the requirement of us. We should ensure all of the circuit to be electrified. If there are any lamp not lighting up before installing the soft film, it should be adjusted and repaced in time. The interior hidden lights should be painted with white paints so as to get a better effect. 4. The air conditioning and fire pipes must be arranged in advance and debug to keep it operating well. After the installation of the air inlet, spray head, and smoke sensor, all of them should meet the requirements of us. 5. After the installation of the piamater ceiling is completed, for example, the paint should repair the gypsum board and should not touch the soft film smallpox.
Q:How to make geomembrane inspection?
Geomembrane is a kind of waterproof barrier material taking high-molecular polymer as the basic raw material of the, mainly divided into: low density polyethylene (LDPE) geomembrane, high density polyethylene (HDPE) geomembrane and EVA geomembrane, which have good errosion resistance to bacteria and chemistry, not afraid the erosion of acid, alkali and salt, testing their resistance to errosion during test.
Q:How to stick mobile phone film?
1. Clean the screen with BG cleaning cloth (or fiber soft cloth, glasses cloth) thoroughly. It is better to clean the screen indoors in a neat condition without air flow to reduce the influence of dust. If there is dust on the screen, bubbles will stay between the membrane and the screen which means the failure of sticking membrane. Membrane will become useless when there is dust between it and the screen which damages the silica gel layer of packaging film. 2. Wipe off the stubborn dirt with BG dedusting paster. If there is stubborn dirt remaining on the screen, clean the screen with dry cleaning cloth. Wet cloth should not be used. Dedusting paster can stick the dust. So it can be used to clean the screen. Stick dedusting paster back to the original backing paper after using it. Then the paster is recycled. 3. Check the membrane. Take the membrane out of the package. Do not tear off the release liner directly. Put it on the screen of the cellphone, check if the membrane is suitable. Make clear of the place to stick membrane. This will help in later steps. 4. Tear off the first release liner partly. Pay attention to not touch the part of protective membrane exposed with your finger. Each cellphone film is composed of three layers. The first and the last are release liners to protect the protective membrane sandwiched between them.
Q:Is there mobile phone film on which fingerprints will not attach?
In terms of fingerprints issues, you can buy the mobile phone film with the matt surface (frosting surface)which is way better than the bright film. However, the light transmittance is low.
