Factory Supply High Quality Membrane Covered Filter Material

 

The production process of membrane-coated filter materials primarily encompasses the following steps:

Melt Spinning: Preparing base material fibers, such as PPS fibers, through the melt spinning method.

Filter Cloth Weaving: Weaving fiber cotton into filter cloth, requiring tightness and uniformity.

Surface Treatment: Applying a coating to the filter cloth's surface to enhance its anti-contamination properties and filtration efficiency.

Membrane Coating: Evenly covering the filter cloth's surface with PTFE membrane to form the membrane-coated filter material. This step necessitates specialized coating equipment and process parameters to ensure a tight bond between the membrane and substrate.

Sewing and Inspection: Sewing the treated filter cloth into bag shapes and conducting quality inspections to ensure product performance and quality.

• High-efficiency Filtration: The membrane-coated filter material boasts an extremely high filtration efficiency of over 99.99%, capable of rapidly and effectively retaining ultrafine dust particles measured in microns.
• Surface Filtration: The PTFE membrane's surface is devoid of through-holes, preventing dust from penetrating the membrane's surface into its interior or the substrate. Only gases pass through, while dust or particles are retained on the membrane's surface. This mode of filtration is known as "surface filtration."
• Low Resistance: Since dust is retained on the membrane's surface and does not enter the filter media's interior, the long-term operational resistance remains lower than that of conventional filter materials.
• High Temperature Resistance: The PTFE membrane exhibits excellent thermal stability, allowing for a wide range of operating temperatures and continuous use under high temperatures.
• Corrosion Resistance: The PTFE membrane possesses superior chemical stability, rendering it highly resistant to corrosion.
• Non-stick and Water-repellent: The PTFE membrane's low surface tension imparts excellent non-stick and water-repellent properties, enabling dust cakes to automatically shed, thereby ensuring long-term stability of equipment resistance.

Membrane-coated filter materials have been widely employed in numerous fields, including industrial dust removal and precision filtration. As dust removal bags or pleated dust filter cartridges, they are installed within dust removal equipment, swiftly and effectively eliminating dust particles from the air, thereby satisfying various industrial dust removal requirements.

Customized filters of different specifications and models are available upon user's request.
