What materials are used for sieves produced by For Laboratory Sieves Suppliers?

For Laboratory Sieves Suppliers produces sieves in a variety of materials, including wire mesh, non-metallic mesh, and specialty mesh, meeting the material requirements for both corrosive and non-corrosive materials.

Wire Mesh

Stainless Steel: Corrosion-resistant, wear-resistant, high-strength, and reusable. Type 316 is more resistant to chloride corrosion than Type 304.

Brass: Low cost, average corrosion resistance, easily oxidized, used for dry, lightly abrasive materials.

High-carbon steel: Hard and wear-resistant, but prone to rust. Often treated with rust-proofing. Used in applications subject to severe wear and where iron contamination is a concern.

Non-metallic mesh

Polyamide (Nylon): Corrosion-resistant and flexible, but not resistant to strong acids and lacking the wear resistance of stainless steel.

Polyester (PET): Low hygroscopicity and dimensionally stable. Used for materials requiring high hygiene or where metal contamination is a concern.

Specialty screens

Electropolished stainless steel: Features smooth pore edges, precise apertures, and resistance to clogging. Used for high-precision screening.

Electroformed screens: Non-woven, precise pore shape, smooth walls, high precision, but fragile and expensive. Used primarily for extremely fine powders below 20μm.

What screen frame materials does For Laboratory Sieves Suppliers produce?

The choice of screen frame material depends primarily on the characteristics of the material being screened (such as corrosiveness, humidity, temperature, hardness, etc.), production process requirements, and cost considerations. Carbon steel is the most common screen frame material, offering low cost and high strength. It is suitable for screening most non-corrosive materials.

Stainless steel resists corrosion from water, steam, and common acids and alkalis, is easy to clean, and has a smooth, non-porous surface, making it suitable for corrosive and hygienic industries.

Plastics (polypropylene, nylon, etc.): Non-metallic materials used for specialized applications. They offer excellent resistance to strong acids and alkalis. Their light weight makes them easy to install and transport, making them suitable for highly corrosive chemicals, materials sensitive to metal ions, and applications requiring anti-static treatment.
