Plastic Hollow Float Balls are spherical fillers or coverage balls manufactured primarily from engineering plastics like Polypropylene (PP) through processes like injection or blow molding.
They are a critical component in various industrial systems, designed to float on liquid surfaces within tanks and towers. Their primary functions are to suppress vapor emissions, reduce heat loss, and facilitate efficient gas-liquid contact for mass transfer and purification.
High Efficiency: The balls feature a large void ratio (typically over 40%) and a stable, overlapping design when packed, which provides excellent surface coverage and sealing, leading to high mass transfer efficiency and effective vapor suppression.
Chemical & Thermal Resistance: Made from materials like PP, they offer excellent resistance to a wide range of chemicals, including acids and alkalis. They can operate continuously in temperatures from 60°C to 150°C.
Lightweight & Durable: The hollow structure gives them a low bulk density, making them easy to handle and install. They are mechanically robust, with a reported pressure resistance of approximately 6 tons per square meter.
Economic & Environmental: By minimizing the evaporation of liquids and volatile chemicals, they help conserve energy and raw materials, reduce operating costs, and significantly lower harmful emissions, contributing to a safer workplace and environmental protection.
The following table lists standard specifications. Custom sizes and materials (like PE) are commonly available
| Diameter (mm) | Wall Thickness (mm) | Specific Surface Area (m²/m³) | Void Ratio (%) | Bulk Density (kg/m³) | Packing Count (pcs/m³) |
|---|---|---|---|---|---|
| φ25 | 1.0 | 200 | 42 | 125 | 41,500 |
| φ38 | 1.2 | 150 | 40-42 | 121 | 22,000 |
| φ50 | 1.5 | 120 | 40-42 | 73 | 10,480 |
| φ76 | Information Varies | Information Varies | Information Varies | ~70 | ~3,200 |
Vapor Suppression: Covering surfaces in acid storage tanks, electroplating baths, and chemical vessels to control fumes and acid mist-4-8.
Water & Wastewater Treatment: Used in condensate storage tanks, demineralized water tanks, and other water treatment vessels to minimize oxygen and carbon dioxide ingress and heat loss-5.
Process Engineering: Serving as random packing in packed towers and scrubbers in petroleum refining, chemical plants, chlorine-alkali production, and environmental gas purification systems to enhance separation and reaction processe
