Inflatable rubber fender/Marine ball introduction
Inflatable fender is a kind of berthing buffer and protection of ship supplies, widely used in ships, offshore facilities, offshore platforms, ports and other fields. Pneumatic rubber fender is more practical and economical than general Marine fender, so it is widely popular.
Rubber fender is a rubber closed container made of hanging gluon cloth as the skeleton material. It can float on the water surface after being filled with compressed air, and it is an important buffer medium for the berthing of ships and ships and the berthing of ships and docks. At the same time, the inflatable rubber fender can absorb the impact energy of the ship's movement, reduce the recoil force of the ship, and greatly improve the safety of the ship's docking.
Air is used as the medium, compressed air is used to absorb the impact energy, so that the ship has flexibility when docked, so as to achieve the effect of anti-collision and anti-collision.
Inflatable rubber fender Features:
1, the absorption of energy is large, the reaction force is small, so as to ensure that neither damage the hull nor damage the shore wall.
2, the installation is simple, portable, in any ship, any sea area is not affected by tides and ship size.
3, good resilience, the product will not be deformed because of the force, after the fender is squeezed, more than 95% of the release is restored to the original shape.
4, good economic performance, fender compared to the same period, more wear-resistant, high service life, cost-effective, reliable quality.
Marine ball fender structure:
Marine ball is divided into: inner rubber layer, strengthening cord layer, outer rubber layer.
The role of the inner rubber layer: to shape the fender, enhance air tightness and ensure no air leakage.
Strengthen the connection layer: improve the strength of the shore fender, increase the tensile strength and increase the pressure.
Outer rubber layer: improve the wear resistance of Marine fender, better protect the inflatable rubber fender body, extend the applicable life
