Introduction of HDPE Geomembrane:
----Geomembrane including LDPE, LLDPE, HDPE, EVA, ECB and PVC geomembrane.
Application of HDPE Geomembrane:
---Prevent leakage disposal in waste burying field, waste water, or waste dregs disposing field.
River bank, lake dam, mine remaining, reservoir, tunnel, liquid storage pool(pit, mine)
Preventing leakage of subway, basement, tunnel, holes
Anti-slot leakage in roadbed and other groundsill
The plan direction laying of dam, the vertical direction laying for groundsill, used in the construction fence and waste material field.
Used in seawater or freshwater feed field.
Used in groundsill of road, highway, railway and waterproof layer of swelling clay and wet collapsed loess.
Preventing leakage on rooftop

- Q:Which standard form of railway construction engineering inspection certificate is for geogrid and geomembrane separation layer? No. 52 or No. 59?
- Q:Does iphone need to stick membrane?
- iPhone can be sticked with membrane: 1. High-definition film is thin, and the visual effect is good. However, it is easily scratched; 2. Frosted film is also thin, but its visual effect is not so good without fingerprint; 3. Tempered film is thinner, and its visual effect is good and resistant to scratch.
- Q:Which mobile phone film is better? film or epidural?
- Buy a better 1 of the dura, to some extent, will affect the sensitivity, but do not stick to the words will inevitably scratch the screen. 2, choose the brand film, because it has quality assurance, technical checks and security
- Q:When can't PDHE impervious film be installed?
- But when the temperature is below zero, it will affect the welding quality of HDPE geomembrane. It is better to carry out construction at a temperature above 4 degrees Celsius. The required temperature tolerance of geomembrane is 77 degrees Celsius below zero.
- Q:what's the weight of eomembrane 200 * 0.58 * 200?
- 1000 g
- Q:What are the differences of geotextiles and geomembranes?
- Geotextiles are fabrics made by weaving. Geomembranes are made by craft of bonding impermeable membranes with geotextiles. Geotextiles perform well in filtration, dewatering, separation, reinforcement and seepage control with properties of good protective effect, light weight, strong strength of extension, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance. The full name of geomembrane is "high density polyethylene film". They have high environmental stress cracking resistance, low temperature resistance, aging resistance and corrosion resistance.
- Q:Landfill geomembrane safety rules.
- Q:Is good to stick the mobile phone film
- There is a certain protective effect on the cell phone, especially the mobile phone film, but in fact, it is not much necessary. For many people, sticking the film is to prevent the phone screen from scratching, but in fact, such as Apple, the hardness of the screen is relatively high, unless it is deliberately scrached, or it is not easy to be damaged. The hardness of nails is relatively low, it is not possible. the mobile phone film will affect the beauty and brightness of pictures, and it is easy to cause visual fatigue of the user. But the mobile phone price is relatively low, and the hardness of the screen is not great, so you can stick the film. In short, There are both advantages and disadvantages.
- Q:What is the function of the wallpaper basilemma
- wallpaper basilemma is a process material covering painted on the wall before the construction of wall. it can prevent water, moisture, and other alkaline substances in the walls extravasates, and thus it has the function which can make the wallpaper or textile wall covering mildewproof, alkali resistant, and anti-moisture.
- Q:how to brush wallpaper basilemma
- First diluted the basilemma with pure water, and then follow the basilemma: Water =1: brushing for 1.5 or two times, the main processing steps of wallpaper base layer: 1, ensure the moisture content of the wall base layer should below the 8%----10%. 2, the wall before putty fumbling in a level should be firm, having no saltpetering, empty and loose. 3, after clearing the wall attachments, on the base level scrape putty 2-3 times, after abrasive paper polished, clean the surface with gauze. 4, painted wallpaper basilemma, the wallpaper basilemma brushing the wall to dry after construction again. 5, construct on the surface of the wall which has been painted with wall paint, and you can not paste wallpaper directly on the wall, and then stripped off the original base layer putty, painted wallpaper basilemma, pasting after the paint drying. 6, old building has construction on the old wall, and the wall is not flat, not very nice to post wallpaper and it needs another special treatment before pasting.
