HDPE Black Plastic Floating Hollow Ball Plastic Shade Ball for Prevent Water Evaporation
HDPE (High-Density Polyethylene):Properties: Corrosion-resistant, UV-resistant, low-temperature tolerance (-50°C to 80°C), high strength, non-toxic, and eco-friendly. Advantages: Ideal for long-term outdoor use with excellent anti-aging performance (10+ years lifespan).
Magnetic Component:Embedded mid-strength magnetic materials (e.g., ferrite or magnetic powder composite) integrated via injection molding.
Color & Light Blocking:Added carbon black masterbatch (2%-5% content) ensures full black appearance with 95%+ shading rate, effectively blocking UV and visible light.
Structural Design: Hollow Sealed Sphere: Filled with air or inert gas, low density (0.93-0.97 g/cm³), strong buoyancy for stable water surface coverage. Surface Treatment: Smooth or micro-textured design to reduce algae attachment and simplify cleaning.
Algae Suppression: Blocks photosynthesis to prevent algae blooms, maintaining water clarity (ideal for fish ponds, shrimp farms, and landscape pools).
Thermal Insulation: Black surface absorbs heat to stabilize water temperature, reducing evaporation in summer and heat loss in winter.
Magnetic Retrieval: Built-in magnets enable quick recovery or positioning (e.g., using magnetic tools to prevent wind drift).
Eco-Friendly Coverage: Replaces chemical algaecides, non-toxic, and reduces odor emissions (e.g., sewage treatment plants).
