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.

Best to use a base film, if the direct wallpaper paste, rubber adhesive is very strong, it is possible to directly attached to the wall of the grass roots to pull off, if you brush a layer of the base film (also called wallpaper partner), the base film can close wall, waterproof, increase adhesion of the walls and wallpaper, brush one day after the wallpaper, etc., no problem

The color of the geomembrane is mostly black, and also green, white, gray, black green and other colors. The main material of geomembrane is high density polyethylene, auxiliary materials are antioxidants, anti UV agent, carbon black, masterbatch and so on, color of the geomembrane depending on the colour of added masterbatch. There is also geomembrane without auxiliary material, and it is transparent.

Geomembrane is not suitable to be in complex pipeline project and constructions. SBS adopts hot melting construction; SBSJS waterproof coating cannot be constructed in below freezing and rainy days, PVC, and the film will need some time to dry, which is not suitable for waterproofing roof. The construction of SBC is complex.
There are several advantages of using geomembranes in mining tailings storage facilities. Firstly, geomembranes act as a barrier, preventing the seepage of potentially harmful substances into the surrounding environment. This helps to protect water sources and ecosystems from contamination. Additionally, geomembranes provide stability and prevent the erosion of tailings, reducing the risk of dam failure and subsequent disasters. They also allow for efficient management of water resources by controlling the flow and retention of water within the storage facility. Overall, the use of geomembranes in mining tailings storage facilities improves environmental protection, safety, and water management practices.
Yes, geomembranes are generally resistant to algae growth. They are designed to be impermeable and provide a barrier against water and other substances, which prevents the growth of algae. Additionally, geomembranes are often made from materials that are not conducive to algae growth, such as high-density polyethylene (HDPE) or polyvinyl chloride (PVC). However, it is important to note that proper installation and maintenance of geomembranes are essential to ensure their effectiveness in preventing algae growth.

We can often see some cooked food or cut fruits in the supermarket wrapped with preservative film. So many people think it is a protective film, and that it is ok to put them into the refrigerator directly when going back home. In fact, the right approach is to tear off the preservative film first befor storage. In order to increase its adhesion, the plastic wrap contains the plasticizer called ethylhexyl ammonia. The plasticizer will cause much damage to the human endocrine system and upset the body's metabolism. Therefore, when storing food, you should first remove the plastic wrap, and don't use any plastic wrap for the hot food. At present, there are three main raw materials for the production of food wrap, namely polyethylene (PE for short), polyvinyl chloride (PVC) and polyvinylidene chloride (PVDC). Most of the plastic wrap on the market use polyethylene as raw material. For it contains no add plasticizers in the production process, it is recognized as the most secure plastic wrap.
