How to Select the Suitable Epoxy Mesh for Filter Media

Epoxy coated wire mesh plays a vital role in hydraulic and air filter products, serving as a support system while providing protection and impact resistance to filter media. With a myriad of specifications available, selecting the most suitable epoxy mesh can be daunting. Drawing from over 20 years of industry experience, we've compiled a concise guide to aid in your selection process.

Understanding Epoxy Mesh Composition

Epoxy mesh consists of substrate wire mesh combined with epoxy powder coating. The substrate mesh materials vary, including Q195 and Al5154, with wire diameters ranging from 0.15mm to 0.3mm and mesh counts from 8 to 30 mesh. These specifications can be customized to meet specific customer requirements.

The epoxy resin coating, comprising epoxy resin, filler, curing agent, and pigment, significantly influences the mechanical and chemical properties of the metal mesh. It reinforces the substrate mesh and provides anti-corrosion properties.

Considerations for Selecting Epoxy Mesh

Different combinations of mesh and powder yield varying properties such as opening size, thickness, weight, flexibility, color, corrosion resistance, and chemical resistance. It's crucial to ensure that the chosen combination falls within feasible parameters. For instance, maintaining a minimum coating thickness of 20–30um is essential to prevent the exposure of the substrate wire mesh.

Optimizing Production Processes

The selection of epoxy mesh should align with the production processes and performance requirements of filters. Factors such as pleating methods, equipment compatibility, and end cap materials play a crucial role in determining the suitability of epoxy mesh.

A. Application-Specific Selection

Choose epoxy mesh based on the intended application of the filters. For instance, air filters commonly utilize Al5154 wire mesh with epoxy resin coating, while hydraulic filters employ Q195 steel wire mesh with epoxy resin coating.

B. Production Process Compatibility

Consider the compatibility of epoxy coated wire mesh with various production processes and equipment. Blade-type high-speed pleaters are suitable for wide-width epoxy mesh, enhancing production efficiency. Gear type pleaters, on the other hand, benefit from epoxy mesh with specific wire diameters and coating thicknesses to improve support and folding efficiency.

C. Filter Processing Technology

Certain filter processing technologies, such as hot-melt pressing with plastic end caps, require epoxy mesh that facilitates pleating while cutting to ensure consistency in width between the mesh and filter paper.

Conclusion

Selecting the suitable epoxy mesh for filter media involves a comprehensive assessment of production processes, performance requirements, and equipment compatibility. By considering factors such as substrate materials, coating properties, and processing methods, manufacturers can optimize filter production and enhance product quality.
