PP Nonwoven Geotextile For Road Construction
PP non-woven fabric is made of polypropylene fibers through processes such as hot melting, spraying, and high-speed air flow to form a network structure, and then undergoes appropriate heat setting, compaction and other processing processes.
1. Has high tensile strength and good anti-penetration performance
2. Can effectively enhance the stability and bearing capacity of soil
3. Excellent backflow resistance
4. Can prevent soil particles from being washed away or eroded
5. Has good anti-aging properties and chemical corrosion resistance
Polypropylene nonwoven geotextile, referred to as PP geotextile, it is a non-woven fabric made of polypropylene fiber as the main raw material.
Material: PP
Weight:100-800g
Width: 1-7m
Length: 50-200m (customizable)
Color; white, black, orange, supports custom colors
Features:
1. Lightweight and excessive strength: PP geotextile has mild weight and exquisite tensile strength, can face up to massive masses and extrusion forces in projects, and has true durability.
2. Good acid and alkali resistance: PP geotextile can face up to the erosion and corrosion of more than a few chemical supplies such as acids, alkalis, salts, etc., and is appropriate for exceptional soil environments.
3. Good climate resistance: PP geotextile has properly climate resistance, can face up to ultraviolet radiation and the results of local weather change, and keep secure overall performance of the material.
4. Good water and air permeability: The floor of PP geotextile regularly has a extraordinary pore structure, which can obtain properly water and air permeability and preserve soil moisture and gasoline exchange.
5. Good environmental protection: PP geotextile is made of environmentally pleasant substances and is non-toxic, odorless and degradable, and will now not pollute the environment.
Application:
1. Water conservancy projects: PP geotextiles are appropriate for anti-penetration, landslide resistance, and erosion resistance in rivers, reservoirs, and dams in water conservancy projects.
2. Foundation engineering: PP geotextiles can be used for soil reinforcement, leakage prevention and soil conservation to enhance the steadiness and reliability of basis engineering.
3. Road engineering: PP geotextile can be used to fortify and stabilize roadbeds and pavements, minimize the incidence of pavement cracks and settlements, and extend the provider lifestyles of roads.
4. Mines and landfills: PP geotextiles can be used for complete administration of mines and reinforcement and anti-seepage of landfills to limit soil and groundwater pollution.
5. Agricultural engineering: PP geotextile can be used in agricultural engineering such as windproof and warmness preservation, soil moisture retention and soil care to promote crop boom and expand yield.
