Hongyue aging resistant geomembrane

Short Description:

Anti-aging geomembrane is a kind of geosynthetic material with excellent anti-aging performance. Based on ordinary geomembrane, it adds special anti-aging agents, antioxidants, ultraviolet absorbers and other additives, or adopts special production processes and material formulations to make it have better ability to resist the aging effect of natural environmental factors, thus prolonging its service life.

Product Detail

Performance Characteristics

Strong UV Resistance: It can effectively absorb and reflect ultraviolet rays, reducing the damage of ultraviolet rays to the molecular chains of the geomembrane. It is not prone to aging, cracking, embrittlement and other phenomena under long-term sunlight exposure, and maintains good physical properties.
Good Antioxidant Performance: It can inhibit the oxidation reaction between the geomembrane and the oxygen in the air during the use process, preventing the decrease of material performance caused by oxidation, such as the decrease of strength and elongation.
Excellent Weather Resistance: It can maintain stable performance under different climatic conditions, such as high temperature, low temperature, humidity, dryness and other environments, and is not easy to accelerate aging due to changes in environmental factors.
Long Service Life: Due to its good anti-aging performance, under normal use conditions, the service life of anti-aging geomembrane can be extended by several years or even decades compared with that of ordinary geomembrane, reducing the maintenance cost and replacement frequency of the project.

Production Process

Raw Material Selection: High-quality high molecular polymers such as high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) are selected as the basic materials, and special anti-aging additives are added to ensure that the materials have good initial performance and anti-aging potential.
Blending Modification: The base polymer and anti-aging additives are blended through special equipment to make the additives evenly dispersed in the polymer matrix to form a blended material with anti-aging performance.
Extrusion Molding: The blended material is extruded into a film through an extruder. During the extrusion process, parameters such as temperature and pressure are precisely controlled to ensure that the geomembrane has a uniform thickness, a smooth surface, and the anti-aging components can fully play their roles.

Application Fields

Landfill: The cover and liner system of the landfill needs to be exposed to the outdoor environment for a long time. The anti-aging geomembrane can effectively prevent the aging and failure of the geomembrane caused by factors such as ultraviolet radiation and temperature change, ensure the anti-seepage effect of the landfill, and reduce the pollution to the surrounding soil and groundwater.
Water Conservancy Project: In water conservancy projects such as reservoirs, dams and canals, anti-aging geomembrane is used for anti-seepage and waterproof treatment. Ordinary geomembrane is prone to aging and damage when in long-term contact with water and exposed to the natural environment, while anti-aging geomembrane can ensure the long-term stable operation of the project and improve the durability of the water conservancy project.
Open-pit Mining: In the tailings pond and spoil ground of open-pit mining, the anti-aging geomembrane is used as an anti-seepage material, which can resist the harsh natural environment, prevent the seepage of mine slag leachate into the soil and water body, and reduce the leakage risk caused by the aging of the geomembrane.
