It is a textile used in civil engineering. Geotextile can be divided into woven aquaculture geomembrane manufacturers, knitted geotextile and nonwoven geotextile according to different processing methods. Woven geotextiles are mostly used in filament woven fabrics and flat woven fabrics, and the material is mainly polypropylene. Warp-knitted composite geotextile is made of glass fiber (or other synthetic fibers) as the reinforcement material, and is compounded with staple fiber needle-punched nonwoven geotextile. Non-woven geotextiles mainly include staple fiber needle punched geotextiles and filament spun clay geotextiles. The selected synthetic fiber materials are polyester, polypropylene, nylon, etc., among which polyester and polypropylene are mainly used.
Regardless of knitted geotextile, woven geotextile or non-woven high quality aquaculture geomembrane, during processing, storage and use, they are susceptible to the combined effects of internal and external factors, and their functions gradually deteriorate, resulting in the eventual loss of application value Called aging. This is a common problem of geotextiles. Its essence is the cracking of molecular chains in the polymer structure, the change of chemical structure, etc., and the microscopic performance is the decrease of geotextile strength and the destruction of microstructure. It is an irreversible change.
It is widely used in the fields of railway, highway, water conservancy, electric power, metallurgy, mining, construction, military industry, seaport, agriculture, etc. It has the effects of drainage, filtration, barrier, reinforcement, maintenance, anti-seepage and leakage prevention. The greater the thickness of the geotextile manufacturer, the higher the resistance. Geotextile, also known as high quality environmental geomembrane, is a water-permeable geosynthetic material made of synthetic fibers by needle punching or weaving.
High strength, due to the use of plastic fibers, can maintain sufficient strength and elongation in dry and wet conditions. Corrosion resistance, long-term corrosion resistance in soil and water with different pH. The water permeability is good because there are gaps between the fibers, so it has good water permeability. Good anti-microbial properties will not damage microbes and worms. It is convenient to construct, because the material is light and soft, so it is convenient to transport, lay and construct.
