Длинный шелковый спанбонд иглопробивной нетканый геотекстиль

Description

Continuous Filament Needle Punched Nonwoven Geotextile is produced from polyester (PET) or polypropylene (PP) continuous filaments through needle punching processes, forming a three-dimensional structure. Длинный шелковый спанбонд иглопробивной нетканый геотекстиль exhibits excellent mechanical and hydraulic properties, making it widely applicable in civil engineering, water conservancy projects, and road and railway constructions for functions such as reinforcement, separation, filtration, drainage, and protection.

Основные характеристики

Характеристики

- UV Resistance

- High-Temperature Resistance (up to 230°C), maintaining structural stability and original physical properties.

- High In-Plane Drainage and Vertical Permeability

- Excellent Creep Resistance

- Resistance to Chemical Corrosion in Soil, as well as Gasoline and Diesel

- High Elongation Under Stress**, enabling adaptation to uneven and irregular substrates.

Функция

• Permeability & Filtration: Geotextiles provide excellent breathability and water permeability, allowing efficient drainage while preventing soil erosion and sand/gravel loss.
• High Hydraulic Conductivity: Forms effective drainage channels to remove excess liquids and gases through evaporation.
• High Permeability Under Pressure : Maintains superior water permeability even under soil and hydraulic pressure.
• Распределение напряжений:Effectively disperses, transfers, or decomposes concentrated stresses to protect soil from external damage.
• Layer Separation : Prevents intermixing of adjacent sand, soil, and concrete layers.
• Химическая стойкость: Made from polypropylene (PP) or polyester (PET) fibers, offering resistance to acids, alkalis, corrosion, oxidation, and heat.
• Легкий вес и простая установка: Reduces construction time, lowers costs, and improves economic efficiency.
• Soil Reinforcement: Enhances soil tensile strength and deformation resistance, improving structural stability and soil quality.

Назначение

• Filtration Material for Soil Layer Separation.
• Drainage Material， for reservoirs, mineral processing, and high-rise building foundations.
• Erosion Control Material，for river embankments and slope protection.
• Reinforcement Material，for roadbeds (railways, highways, airport runways) and swamp road construction.
• Frost & Freeze Protection Insulation Material.
• Anti-Cracking Material， for asphalt pavements.
