The three-in-one wear-resistant lining plate is a functional composite made of high-strength alumina ceramic, elastic rubber layer, and mild steel plate via hot vulcanization or adhesive bonding. The ceramic layer (Al ₂ O ₃ content ≥ 92%, HRA hardness ≥ 85) provides surface abrasion resistance; the intermediate rubber layer (Shore A hardness 60 ± 5, tensile strength ≥ 12 MPa) absorbs impact loads and reduces noise; the steel plate layer (Q235B, thickness 3-10 mm) serves as a structural base for bolt or weld fixing. This product integrates the properties of three materials into a single component, suitable for high-wear and medium-to-low impact industrial conditions. Compared with traditional single-material linings, the three-in-one structure offers quantifiable advantages in wear life, installation efficiency, and system protection. The ceramic surface limits wear rate to ≤0.1 mm/1000 h (dry silica sand sliding condition), providing a service life 4-8 times longer than that of high ma...

Plastic tower packing is a widely used random or structured filling material in chemical separation processes, primarily manufactured from polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), and polyvinylidene fluoride (PVDF). Its advantages include low density (PP density approx. 0.90–0.92 g/cm³), high corrosion resistance (suitable for most acids, alkalis, and organic solvents), and significantly lower manufacturing cost compared to metal or ceramic packing. The operating temperature of plastic packing generally does not exceed 100°C (PP) to 150°C (PVDF), and it is suitable for atmospheric and low-pressure conditions. Typical plastic tower packings include Pall rings, cascade rings, Intalox saddles, and snowflake rings. For a Φ25 mm Pall ring made of PP, the specific surface area is approximately 200–220 m²/m³, void fraction reaches 90%–92%, and bulk density is about 75–85 kg/m³. Due to structural optimization, cascade rings exhibit 20%–30% lower pressure drop and 10%–15...

The wear-resistant alumina ceramic cuttable perforated plate is a functional ceramic sheet made from high-purity alumina (Al₂O₃) through high-temperature sintering, offering excellent wear resistance and impact strength. While retaining the high hardness of alumina ceramics, this product allows precise cutting and hole drilling using laser or diamond tools, making it suitable for applications such as mineral sorting, material conveying, wear-resistant linings, and chemical filtration. Standard alumina content ranges from 92% to 99.7%, with bulk density of 3.6–3.9 g/cm³, Rockwell hardness HRA 80–90, and flexural strength ≥300 MPa. Compared with conventional metal or rubber liners, this alumina ceramic plate exhibits 5–8 times higher wear resistance, significantly reducing equipment maintenance frequency over long-term operation. Its low friction coefficient (≤0.2) and high-temperature resistance (operating range -50°C to 1200°C) ensure structural stability in high-temperature dust envir...
