Road Construction PP Short Fiber Non-woven Geotextile
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. Light weight and high strength: Polypropylene geotextile has moderate weight and high tensile strength. They can withstand sufficient extrusion forces during engineering and are very durable.
2. Good acid and alkali resistance: PP geotextile can withstand the erosion and corrosion of a variety of acids, alkalis, salts and chemical resources, and performs well in harsh soil environments.
3. Good weather sealing resistance: PP geotextile has extremely strong weather sealing resistance, can withstand the sealing consequences of ultraviolet radiation and local weather changes, and can maintain the integrity of the material's normal acceptance of the building.
4. Good water permeability and air permeability: Polypropylene geotextile ground usually has a good pore structure, has good water permeability and air permeability, and can maintain soil moisture and fuel exchange.
5. Good environmental protection: PP geotextiles are made of well-known environmentally friendly raw materials. Non-toxic, odorless, degradable and will not affect environmental pollution.
Application:
1. Water conservancy projects: PP geotextiles have remarkable anti-seepage, landslide resistance and erosion resistance in rivers, reservoirs and dams in water conservancy projects.
2. Basic engineering: PP geotextile can be used for hard soil, cease leakage, soil fixation, and beautification to make certain the balance and reliability of labor-saving projects.
3. Road engineering: PP geotextiles can be used to toughen and stabilize roadbeds and pavements, stop pavement cracks and settlements, and lengthen the carrier existence of roads.
4. Mines and landfills: PP geotextiles can be used for the ordinary administration of mines and the reinforcement and anti-seepage of landfills to restrict the air pollution of soil and groundwater via air.
5. Agricultural engineering: PP geotextiles can be used in agricultural engineering such as wind safety and heat preservation, soil moisture retention, soil care, etc. to promote the prosperity of plants and achieve higher yields.
