HJ107 (10-40 mesh)
Overview
HJ107 (10-40 mesh) is a granular material primarily used in industrial applications where controlled particle size distribution is critical. The 10-40 mesh specification indicates particles ranging from approximately 0.42mm to 2.0mm in diameter, making it suitable for processes requiring specific flow characteristics or surface area properties. This material is commonly employed as a substrate or support medium in various chemical processes. Its particle size distribution offers an optimal balance between surface area and flow dynamics, making it versatile for both packed bed and fluidized bed applications across multiple industries.
Physical and Chemical Properties
The physical properties of HJ107 (10-40 mesh) include high porosity and thermal stability, with typical operating temperatures ranging up to 500°C depending on the specific formulation. Its granular form provides excellent mechanical strength while maintaining sufficient surface area for effective interaction with gases or liquids. Chemically, HJ107 demonstrates resistance to most acids and bases under normal operating conditions. The material's inertness makes it suitable for applications where chemical interference must be minimized. Bulk density typically ranges between 0.6-0.8 g/cm³, though this can vary based on particle shape and size distribution within the 10-40 mesh range.
Main Applications
HJ107 (10-40 mesh) finds widespread use in industrial water treatment systems as a filtration medium, particularly for removing suspended solids and certain dissolved contaminants. Its particle size distribution allows for efficient filtration while maintaining reasonable flow rates and backwashing characteristics. In petrochemical applications, this material serves as a catalyst support bed in various refining processes. The 10-40 mesh size provides optimal gas/liquid distribution and catalyst utilization efficiency. Additional applications include use in air purification systems, where it may serve as an adsorbent or as a substrate for specialized coatings.
Safety and Storage
While HJ107 (10-40 mesh) is generally considered non-hazardous, proper handling procedures should be followed to minimize dust generation. Workers should use NIOSH-approved dust masks when handling large quantities, and eye protection is recommended to prevent particle irritation. Storage requirements include keeping the material in sealed containers or covered bulk storage areas to prevent moisture absorption and contamination. The product should be stored away from strong acids, bases, and oxidizing agents. Shelf life is typically several years when stored properly, though performance characteristics should be verified before use in critical applications after extended storage periods.
B2B Procurement Guide
When procuring HJ107 (10-40 mesh), buyers should specify not only the mesh size range but also required tolerances for particle size distribution. The industry standard allows for up to 5% variation outside the specified mesh range, though tighter tolerances may be available at premium pricing. Quality verification should include testing for bulk density, attrition resistance, and chemical composition consistency. For catalytic applications, additional specifications regarding surface area and pore size distribution may be required. Bulk shipments typically offer the best value, with prices decreasing significantly at tonnage quantities. Lead times can vary from 2-6 weeks depending on supplier inventory and customization requirements.
