Anti-seepage and anti-corrosion geomembrane Is a waterproof barrier material with high molecular polymer as basic raw material, Geomembrane It is mainly used for engineering waterproofing, anti-seepage, anti-corrosion and anti-corrosion. Polyethylene (PE) Waterproof geomembrane is Made of polymer material, it has excellent chemical corrosion resistance, environmental stress cracking resistance, high service temperature range and long service life .
Characteristics and application of anti-seepage and anti-corrosion geomembrane
- Characteristic :
- Imperviousness :Hengrui anti-seepage geomembrane has high strength tensile mechanical resistance, excellent elasticity and deformation ability, and can effectively prevent seepage, waterproof and leakage .
- Chemical resistance :Geomembranes have good chemical corrosion resistance and are suitable for a variety of chemical environments .
- Environmental stress cracking resistance :Geomembrane has excellent environmental stress cracking resistance .
- Strong adaptability :The geomembrane has strong adaptability to deformation, low temperature resistance and frost resistance .
Anti-seepage and anti-corrosion geomembrane The main uses of the :
- Landfill :In landfill, anti-seepage geomembrane is used for bottom anti-seepage, preventing harmful substances in garbage from penetrating into groundwater and protecting groundwater resources .
- Hydraulic engineering :In water conservancy projects, anti-seepage geomembranes are widely used in anti-seepage and anti-seepage layers of reservoirs, dikes, tunnel linings and other projects. By covering anti-seepage geomembrane, the seepage of groundwater can be effectively prevented, and the safety and reliability of water conservancy projects can be enhanced .
- Agricultural sector :In the agricultural field, anti-seepage geomembranes can be used for Greenhouse 、Paddy fields And Orchard Etc. Covering anti-seepage geomembrane can reduce the waste of water resources and provide a stable agricultural environment .
- Mining sector :In the mining sector, particularly in Tailings pond During the construction, anti-seepage geomembrane is used to prevent waste from polluting the environment. It is usually laid on the bottom and side walls of tailings ponds to prevent seepage .
- Environmental Protection Engineering :In environmental protection projects, anti-seepage geomembranes are used in Sewage Treatment Plant 、Contaminated soil remediation project Etc. In sewage treatment plants, anti-seepage geomembranes are used to prevent seepage in sewage pools to prevent sewage from leaking into groundwater; In contaminated soil remediation projects, it serves as an isolation layer to prevent pollutants from spreading .
Principle and characteristics of anti-seepage and anti-corrosion geomembrane :
- Barrier action :Impermeable geomembranes have a good barrier effect and are able to prevent the penetration of moisture, chemicals and harmful gases. Its molecular structure is dense, its porosity is low and it has excellent barrier performance .
- Osmotic pressure resistance :Hengrui impermeable geomembrane can withstand the extrusion from soil pressure and water pressure, maintaining its integrity and stability. The use of multilayer composite geomembrane can improve the anti-seepage pressure ability .
- Chemically inert :Anti-seepage geomembrane has good chemical inertness, can withstand various acid-alkali corrosion and organic solution erosion, and maintain long-term stability and reliability .
- Weather resistance :After special treatment, the anti-seepage geomembrane has good anti-aging performance and weather resistance, and can withstand the unfavorable environmental factors caused by long-term ultraviolet radiation, alternating high and low temperatures .
Construction and maintenance of anti-seepage and anti-corrosion geomembrane
- Construction method :The construction of Hengrui anti-seepage geomembrane usually includes steps such as laying, welding or bonding. High density polyethylene ( HDPE) The anti-seepage membrane is often welded by hot melt to ensure the waterproof performance of the joints .
- Maintenance :Regularly check the integrity of geomembrane, timely repair damaged or aged parts to ensure its long-term effective use .
To sum up, anti-seepage and anti-corrosion geomembranes play an important role in civil engineering and environmental protection because of their excellent anti-seepage and anti-corrosion properties and wide application fields.
