The original data of geotextiles are that polymer geomembrane polymers are chain joints. It is very sensitive to oxidation and is prone to degradation reaction and AC response, resulting in damage of data. Therefore, the service life of geotextiles has attracted the attention of engineers. Oxidation involves thermal oxidation caused by heat and temperature, as well as the photooxidation of ultraviolet light in sunlight.
Methods / steps
Geotextiles are based on raw material, technology and disposal for short staple needled geotextiles, spunbonded needling nonwoven geotextiles, and compound geotextiles. In the meantime, the short staple needled geotextiles has the characteristics of anti-aging, good flexibility and simple construction. It can be used for maintenance and reinforcement of highway and hydraulic construction. Spunbonded nonwoven geotextiles are also known as geotextiles. In addition to the characteristics of short silk geotextiles, they have the function of closing, and the primary use is the protection and seepage prevention of the tunnels and waste landfills. Geotextiles are mainly used to protect the geotextiles from damage, and their impervious effects are usually used for seepage prevention of artificial lakes and Landscape Lakes.
All kinds of raw materials are resistant to ultraviolet radiation. Polypropylene and amine are worst and lighter than deep. Because aging is carried out gradually from the surface to the inside, the old cloth is thicker and thinner. Short staple needled geotextiles and spunbonded nonwoven geotextiles are composed of water permeable geotextiles composed of needle punching or weaving. They are characterized by high strength, high microorganism and complete standards.
