What are the requirements for geomembrane in the engineering environment?

Geomembrane is an engineering material, and its design should first understand the engineering requirements for geomembrane. According to engineering requirements for geomembrane, extensively refer to relevant standards to design product performance, state, structure and manufacturing process methods.

The engineering environment requires geomembrane. For any material used in engineering, especially long-term engineering, the service life of the material is the main factor that determines the engineering life. The conditions of use of materials in engineering are called “engineering environment”. The engineering environment includes factors such as force, heat, medium and time. Acknowledgement factors usually rarely exist alone, but are often superimposed. They also act on the geomembrane. As a result, they have an irreversible impact on the inherent characteristics of the engineering materials, until they are destroyed. The engineering environment is extremely complex, so the geomembrane must be water resistance, acid and alkali resistance, friendly solvent resistance, resistance to active substances, resistance to metal ions, resistance to microorganisms, aging resistance, mechanical properties, and creep resistance. , And comprehensively analyze the construction performance, and select a geomembrane that is more suitable for the engineering environment. For example, landfills, sewage treatment plants, chemical plants, and tailings ponds need to use American standard or urban construction 1.5mm-2.0mm geomembrane, fish ponds and lotus ponds use 0.3mm-0.5mm new materials or national standard geomembrane, reservoir pool Use national standard 0.75mm-1.2mm geomembrane, tunnel culvert should use EVA 1.2mm-2.0mm waterproof board, etc.
