Factors that directly affect the service life of filter cloth
2026-02-06
The service life of filter cloth directly affects production efficiency and operating costs. Indeed, the quality of filter cloth is the core factor determining its lifespan; however, “quality” is a comprehensive concept that encompasses the entire chain—from raw materials to usage and maintenance.
1. Importance of Material Selection: This is a fundamental factor—different materials exhibit vastly different physical and chemical properties. Common materials and their characteristics are listed below.
① Polyester (PET): It has good acid resistance, moderate alkali resistance, and excellent abrasion resistance, making it the most commonly used filter cloth material.
② Polypropylene (PP): Exhibits excellent acid and alkali resistance, but has poor temperature resistance (<90℃) and moderate abrasion resistance. It is suitable for applications involving highly corrosive environments.
③ Polyamide (nylon, PA): Offers excellent wear resistance and good alkali resistance, but is not resistant to strong acids. Suitable for applications involving severe abrasion.
④ Polyethylene (PE): Its properties are similar to those of PP.
⑤ Aramid: Resistant to high temperatures, corrosion, and boasts high strength; however, it is expensive and used in extreme operating conditions.
⑥. PVDF/PTFE: With its exceptionally strong corrosion resistance and high-temperature tolerance, it is the ultimate choice for handling highly corrosive and high-temperature materials—but it comes at a very high price.
