Uhmwpe Navigation Buoy - China

Innovations of UHMWPE Marine Buoys

I.

Maintenance-free:

1, The colour is materials' own colour.

There is no need to paint in 10 years, saving manpower and resources for painting.

2, The floating body has strong self-lubrication, and any water growth could not adhere the tail pipe and floating body, saving time and manpower to shove it.

3, The buoy is higher anti-impact, so it can greatly reduce the chances of being damaged and save manpower and resources to repair.

4, The ballast, treated by anti-corrosion, is placed into the closed tail pipe, avoiding water corrosion .

II.

Impact-resistant:

1 - The material of floating-body has a higher degree of flexibility and hardness.

( The Rockwell hardness of floating-body material is 40, while the Standard Steel material is 45), when impacted by external power, it can absorb the energy rapidly and restore the prototype.

2 - With light weight and small inertia, when impacted, the buoy can quickly shift to resolve the impact force, avoiding damage.

3 - With higher flexiblility, anti-stretch, and tear strength, the floating buoy can maximize the absorption of impact force.

4 - The floating body is designed with special structure, the polyurethane foam's pouring density ≥46kg/m3, which plays a strong support to the floating body, ensuring the floating body can quickly resore after impacted without deformation.

5 - The lamp bracket uses composite materials, many improvements have been made on the basis of national standard.

The security, anti-impact ability, life expectancy have been substantially increased.

6 - Floating body is connected with lamp bracket by 316L-M20 marine grade stainless steel bolts

7 - New safety guard has powerful anti-deformation capability and improves the protection of lighting and solar panels.

III.

Long life:

1 - With high chemical stability and high anti-corrosion, the buoy will not decompose for decades in the seawater, meanwhile, it will not pollute the water.

2 - The floating body and tail pipe are very resistant to outdoor ultraviolet radiation.

It will not be aging for decades and the mechanical properties will not change.

3 - Lamp bracket is specially treated for anti-rusty, so its working life could be more than 20 years.

4 - With special structure, the ultimate working load of each lifting eye will be more than 60 tons.

IV.

High Environmental Protection

1 - Imported Germany pigment is used, so the color is material’s own color, no pollution to environment.

2 - No anti-fouling paint used, so it will not pollute environment.
