Common Issues and Solutions for Industrial Filter Cloths (Ⅱ)

Filter cloth is the key part of filtration equipment, directly affecting separation performance and playing a vital role in solid-liquid separation. Various issues may arise during use. Below is a summary of common problems and corresponding solutions to help improve filtration efficiency and extend filter cloth lifespan.

⑤ Decline in Filtration Efficiency
Causes: Blocked or deformed; changes in material properties.

Solutions:

Filter cloth maintenance: Regularly inspect; replace aged cloth in time.

Pre-treatment of materials: Remove large particles via sedimentation, centrifugation, or screening.

Filter cloth selection: Choose filter cloth with finer pores or better match to material properties.

⑥ Permeation or Leakage
Causes: Cloth damage, poor stitching, or seal failure.

Solutions:

Inspection and replacement: Stop operation and replace damaged cloth immediately.

Multi-layer design: Use composite filter cloth or add backing layers to enhance sealing.

Sewing technique: Apply heat sealing or use high-strength thread to prevent leakage through needle holes.

⑦ Short Service Life
Causes: Material aging, overload operation, insufficient maintenance.

Solutions:

High-quality cloth: Opt for reputable brands (e.g., Sefar, NMO, Bolian).

Parameter optimization: Maintain proper pressure and temperature during filtration.

Regular maintenance: Set up routine cleaning and replacement schedules to avoid overuse.

⑧ Static Build-up
Applicable Scenarios: Dust filtration in industries like chemicals and mining.
Solutions:

Anti-static cloth: Incorporate carbon fibers or conductive yarns.

Environmental control: Increase ambient humidity or install static eliminators.
