At present, the production and application of geomembrane are developing rapidly, and there are many studies on geomembrane, but there are relatively few studies on the aging properties of geomembrane. Geomembrane as an engineering material, its aging performance indicators directly affect the life, safety, and reliability of the project. However, many buyers are very concerned about textured hdpe geomembrane price. Therefore, the research on the aging properties of geomembrane has high economic and strategic significance.
The American Society for Testing and Materials (ASTM) defines geomembrane as Any textile that is used with foundations, soil, rock, earth, or any other civil construction material and that is part of man-made engineering or system. Geomembrane is used together with foundation, soil, rock, soil or other building materials, and uses geomembrane to strengthen, protect, drain, filter, isolate, and prevent seepage. Geomembrane has been called “four major building materials” together with cement, steel, and wood.
Geomembrane can be divided into woven geomembrane, knitted geomembrane, and non-woven geomembrane according to different processing methods. The woven geomembrane is currently used in filament woven fabrics and flat woven fabrics, and the material is mainly polypropylene. The warp-knitted composite geomembrane is made of glass fiber (or other synthetic fiber) as a reinforcing material and is compounded with a staple fiber needle-punched nonwoven geomembrane. Non-woven geomembranes mainly include short-fiber needle-punched geomembrane and filament-spun clay film. The selected synthetic fiber raw materials are mainly polyester, polypropylene, nylon, etc., mainly polyester and polypropylene. So don't choose an inappropriate geomembrane because of the price of the geomembrane.
Whether it is knitted geomembrane, woven geomembrane or non-woven geomembrane, it is easy to be affected by internal factors and external factors during processing, storage, and use, and its performance is gradually deteriorated, resulting in the final loss of use value. Foraging. This is a common problem in geomembranes. Its essence is the breakage of molecular chains in polymer structures, changes in chemical structure, etc. Macroscopically, it shows the decline of geomembrane strength and macrostructure damage, which is an irreversible change.
