Rotary Vacuum Disc Filter Cloth
Properties of Rotary Vacuum Disc Filter Cloth
1. Material Composition:
Polyester (PET): Known for its excellent mechanical strength, chemical resistance, and durability. Suitable for high-temperature applications.
Polypropylene (PP): Offers high resistance to acids and alkalis, making it ideal for chemical processing industries.
Nylon: Provides superior abrasion resistance and elasticity, suitable for applications requiring high tensile strength.
2. Structural Design:
Multi-layer Construction: Typically composed of multiple layers of fabric, each serving a specific purpose, such as filtration, support, and drainage. The layered design enhances overall filtration efficiency and durability.
Pore Size and Weave Pattern: Available in various pore sizes and weave patterns (plain weave, twill weave, and satin weave) to meet different filtration requirements. The choice of pore size and weave pattern affects the flow rate, filtration efficiency, and cake release properties.
3. Physical Properties:
Thickness: Ranges from 1.0 mm to 2.5 mm, depending on the application and required filtration efficiency.
Weight: Typically between 300 to 900 grams per square meter (gsm), with heavier fabrics offering greater durability and filtration capacity.
Permeability: Measured in terms of air permeability (CFM), it determines the rate at which liquid can pass through the cloth. Higher permeability is suited for applications requiring faster filtration rates.
4. Treatment and Finishing:
Calendering: A process of passing the fabric through heated rollers to smooth and compact the surface, enhancing cake release and reducing blinding.
Heat Setting: Stabilizes the fabric dimensions, improving structural integrity and performance under varying temperatures.
Edge Reinforcement: Provides additional strength to the edges, preventing fraying and extending the lifespan of the filter cloth.
