1. Appearance: White spherical shape, smooth surface, with no obvious impurities, damage, or deformation.
2. Specifications and Dimensions: Diameter typically ranges from 1.0-2.5mm (can be customized as required), with a sphericity uniformity deviation not exceeding ±0.2mm.
3. Density: Bulk density is 0.38-0.45g/cm3, and wet density is 1.0-1.1g/cm3.
4. Porosity: Internal porosity of the sphere is ≥80%, facilitating fluid penetration and impurity retention.
5. Temperature Resistance: Maintains stable physical form and performance within a temperature range of -10°C to 80°C, with no softening or brittleness.
6. Corrosion Resistance: Exhibits good chemical stability in acidic and alkaline environments with pH values of 4-9, without dissolution or significant degradation.
7. Mechanical Strength: Compressive strength is ≥0.3MPa; the spheres are resistant to breakage and adhesion after repeated rinsing, with a recovery rate of ≥95%.
8. Filtration Performance: Removal rate for suspended particles with a size ≥5μm is ≥85%, and filtration speed can reach 15-30m/h (adjusted based on water quality).
