high strength plastic scraper Non-Metallic Sludge Scrapers for Corrosive Media | 18-Yr Expertise

A high strength plastic scraper is engineered to provide the structural integrity and mechanical durability required for the demanding application of sludge collection, while retaining all the benefits of non-metallic construction. The misconception that plastic implies weakness is addressed through the use of advanced engineering thermoplastics and composite materials that offer exceptional strength-to-weight ratios. Materials like UHMW-PE (Ultra-High-Molecular-Weight Polyethylene) possess extremely long polymer chains, resulting in high impact strength and outstanding resistance to deformation under load. For larger diameter clarifiers requiring long spans, the structural arms of the scraper can be designed as box beams or trusses using these high-strength polymers, often with internal reinforcing, to prevent deflection and ensure every part of the blade maintains contact with the tank floor. Glass-fiber reinforced polymers (GFRP) can also be incorporated into critical stress points to provide additional tensile strength and stiffness comparable to steel in many applications. This focus on structural design ensures that the scraper can withstand the initial forces of startup in a tank with accumulated sludge, the ongoing torque required to move settled solids, and any potential unexpected obstructions, all without bending or failing. We utilize these high-strength materials and sophisticated engineering design to manufacture scrapers that are not only corrosion-proof but are also mechanically robust enough to handle the toughest conditions.
