The role of geomembrane
Isolate sources of pollution and protect groundwater resources and soil from damage. As an anti-seepage barrier to protect precious water resources from being leaked in vain, improve the utilization rate of water resources in reservoirs, channels, artificial lakes, rivers and other facilities, thereby saving a lot of water resources.
Four major application areas of geomembrane
1.Ecological and environmental protection field
Hazardous waste disposal site/domestic waste landfill/fly ash landfill/mining tailings pond/power plant ash dam/oil tank area anti-seepage/evaporation pond anti-seepage/artificial wetland/intensive livestock and poultry breeding
2.Building waterproof field
Planting roof/underground garage roof/underground building side wall/bottom
3.Water conservancy and agriculture field
Reservoir/diversion channel/river course/watershed management/fish and shrimp breeding pond/lotus pond
4.Traffic engineering field
High-speed rail/subway/railway/highway
The characteristics of 6 kinds of geomembranes
HDPE double-glossy geomembrane: “Tianhai” HDPE double-glossy geomembrane is made of high-quality polyethylene virgin resin, which is copolymerized by four-layer co-extrusion blow molding process or double-layer co-extrusion flat extrusion process technology. It has the characteristics of good mechanical properties, high tear resistance, strong deformation adaptability, puncture resistance, anti-aging, anti-ultraviolet, oil, hydrochloric acid and alkali resistance, high and low temperature resistance, anti-corrosion and non-toxic, long service life, waterproof, anti-seepage, moisture-proof The effect is good.
HDPE single and double rough geomembrane: Tianhai “HDPE single and double rough geomembrane” has two processes: flat extrusion flower process or nitrogen foam process, in which the height of the column point of the embossing process can reach more than 0.4mm, reaching the American standard Standard, more suitable for steep slope or vertical slope engineering needs, improve engineering stability.
Black and green two-color geomembrane: “Tianhai” black and green two-color geomembrane is produced by double-layer co-extrusion process, and the material can be divided into HDPE \ LLDPE \ EVA \ ECB and so on. The main feature is that the colors on both sides are black and green respectively. When in use, the green is up and the black is down. It is mainly used for covering and has an aesthetic effect.
LLDPE geomembrane: “Tianhai” LLDPE geomembrane is a geomembrane made of special linear low density polyethylene resin, which has extremely high elongation and flexibility, and is very suitable for projects with uneven settlement or large local settlement.
Thermally inert reflective geomembrane: The thermally inert reflective film is made through a three-layer co-extrusion process. The core layer and the lower layer of the product remain black, without affecting any technical performance of the film. By changing the composition of the upper layer, adding pure UV additives white paint. On the premise of not reducing the performance indicators of the product, the product has obtained unique advantages in application functions. It is a revolutionary superior product created by “Tianhai” that can adapt to various anti-seepage applications.
Composite geomembrane: “Tianhai” composite geomembrane is a geosynthetic material composed of geotextile (non-woven fabric) and polymer material (HDPE / LLDPE / EVA film, etc.), calendered and thermally melted. It has the properties of tensile resistance, tear resistance, high bursting strength, root puncture resistance, anti-aging and other properties, fast stress dispersion, small displacement, fast construction and low cost.
