What Kind Of Geotextile Is Used In The Landfill?
Polyester geotextiles are often used in landfills, including polyester filament geotextiles, polyester woven geotextiles, and polyester staple fiber needle-punched geotextiles. Among them, filaments and staple fibers are commonly used.
However, in comparison, the performance of polyester filament geotextile is better than that of polyester staple fiber needle-punched geotextile. Why do you say that? Let's analyze it. As far as the degree of stretching is concerned, the filament is about 70% higher than the staple fiber geotextile. As far as the tensile strength is concerned, the filament is about 50% higher than the staple fiber, and the filament is anti-blocking. Geotextile also has better advantages.
Although polyester geotextiles have poor resistance to alkaline substances, they are still very good in resisting acids. However, it should be noted that polyester geotextiles cannot be used alone in landfills, but must be used in conjunction with Use good performance plastic film together, and the main function of polyester geotextile is to protect and isolate.
Polyester is also widely used, which also benefits from the functions and performance of polyester geotextiles. So what are the applications of geotextiles?
1. The common polyester geotextile is mainly used for roadbed treatment, because its strength and toughness are very good, and it has a very good filtering effect, so it is often used as a reinforcing material or a filtering material when building roads use.
2. On some temporary banks or grasslands, a layer of geotextile will be laid according to actual needs. The main purpose is to prevent soil erosion and help plants grow better.
3. When building a dam, the dam foundation is the foundation of the entire dam. The quality is still very important, especially in the treatment of drainage and filtration. Polyester geotextile is often used as the filtering material for drainage pipes and drainage ditch.
Although there are many applications of polyester geotextiles, do not use them in saline-alkali areas as much as possible, because the alkali resistance of polyester geotextiles is not as good as the acid resistance, and all aspects of its performance will be reduced when exposed to alkali for a long time.
