Structural features
Foam Core
Energy absorption and reaction force aspect: Foam core has unique physical properties, when impacted by external forces, its internal structure can effectively absorb and transform the energy exerted by the outside world through its deformation and other means, thus preventing the energy from rebounding in the form of a larger reaction force. For example, when the impact force generated by the collision between the vessel and the fender when docking acts on the foam core, the foam core will act like a “cushioning sponge” and gradually absorb the energy brought by the impact force, so that the vessel will not be damaged due to the excessive reaction force, which guarantees the relative smoothness of the docking process.
Buoyancy retention: Even if the foam core has suffered serious damage such as puncture, it can still maintain a certain buoyancy. This is because the foam core itself is usually made lightweight and has a certain closed-cell structure, and there are a lot of spaces inside it that can accommodate air and other lightweight media, these spaces will not be completely lost due to localized puncture, and can still provide sufficient buoyancy support. It can continue to play its role in safeguarding the safety of water objects and other related roles.
The foam core absorbs energy while maintaining a low reaction force. It remains buoyant even when punctured.
Tire Chain Mesh Protection Layer
Overall mesh protective structure formation:The outer layer applies the tire chain mesh protection layer, which builds a strong mesh structure by combining tires and chains in a certain layout and connection. Tires are connected and intertwined in this mesh structure, and chains are interspersed to strengthen and stabilize them, just like a tight and strong net covering the outer layer of the fender, when there is a collision or extrusion of external objects, this net can disperse the external force by its structure, avoiding excessive pressure on the local area, and effectively protect the internal structure of the foam core and other structures from damage.
Cushioning and pressure-resistant ability to improve:The tire itself has elasticity, and when subjected to external forces can occur to a certain degree of deformation, to play a cushioning effect. For example, when a heavy object hits the fender, the tire can first compress through its elasticity to cushion off part of the impact, reducing the amount of force transmitted to the internal structure. The chain is mainly to enhance the overall pressure resistance, the chain is usually made of high-strength metal, and its rigidity qualities make it in the face of greater pressure, the whole mesh structure is not easy to be crushed deformation, can maintain the overall shape, ensuring the fender protection in the complex stress situation of stability and protection performance.
Polyurethane outer skin
Corrosion resistance guarantee:The polyurethane skin covers the foam core and the tire chain mesh, forming an effective protective barrier. In many use environments, the fender may come into contact with various corrosive substances, such as salt contained in seawater, chemical pollutants present in the waters near some chemical terminals, etc. The polyurethane coating has good chemical stability. Polyurethane coating has good chemical stability, it can prevent these corrosive substances from contact with the internal foam core and the tire chain mesh protective layer, preventing chemical erosion on its structure and performance damage, thus extending the service life of the entire fender, to ensure that it can play a stable protective role for a long time in harsh or complex environments.
Overall, this structure through the foam core of energy absorption and buoyancy maintenance, tire chain net protection layer of strong protection, and polyurethane outer skin of corrosion protection of these aspects of cooperation, forming a more comprehensive and reliable fender structure, can adapt to a variety of complex use of the environment and working conditions.
Core Advantage
High Impact Resistance: The core design of this fender is the combination of foam core and tire chain link mesh. Foam core itself has certain cushioning characteristics, while the tire chain net is like a tough protective net. This combination structure can efficiently absorb and disperse energy during the berthing process, whether it is a slight collision when approaching slowly, or under bad sea conditions, such as high intensity impact between the ship and the quay due to strong winds and waves. It is like an energy “sponge” that gradually dissipates the impact force, thus ensuring that the dock facilities as well as the ship itself are protected from excessive damage, always providing a stable and reliable protective barrier to safeguard the safe conduct of berthing operations.
Strong durability: The tire chain mesh layer is an important support for the durability of the foam fender. Its special material and weaving structure give the fender excellent anti-wear performance. In long-term frequent use scenarios, such as busy international ports, there are a large number of different types of ships of different tonnage berthing frequently every day, the fender will continue to suffer from friction, extrusion and collision of the ship. At this time, the tire chain mesh layer, with its high strength and wear resistance, can effectively resist the erosion of these external forces, significantly reduce the degree of wear and tear on the surface of the fender, and maintain its structural integrity and protective effect. At the same time, in the face of extreme climatic conditions, whether it is high temperature, high humidity and strong ultraviolet irradiation in the tropical region, or cold, freezing and frequent temperature changes in the frigid region, the tire chain mesh layer can show a strong adaptive ability. It can effectively prevent the external environmental factors on the fender internal material erosion, further enhance the fender’s anti-aging and corrosion resistance characteristics, greatly extending the service life of the fender.
Low maintenance cost: Foam fender has significant advantages in maintenance cost. Traditional airbag fenders need to be regularly inflated, pressure monitoring and airtightness checks and other maintenance work to ensure its normal operation. These maintenance operations not only require specialized equipment and technicians, but also once a link is negligent, it may lead to airbag leakage, pressure imbalance and other problems, which will affect the fender’s protective performance, and even cause safety accidents. Foam fenders do not need to be inflated, completely getting rid of the dependence on air pressure maintenance, and fundamentally avoiding a series of problems brought about by the failure of the inflatable system. In addition, the chain link fence and tire layer of the foam fender adopts the innovative design concept of easy replacement. When the fender is damaged due to local wear and tear or collision during long-term use, the maintenance personnel can easily and quickly replace the damaged part individually, without the need to dismantle or replace the whole fender on a large scale. This modular design greatly reduces the difficulty and cost of maintenance, shortens the maintenance time, effectively reduces the downtime of the terminal caused by fender maintenance, improves the operational efficiency of the port, and brings significant economic benefits for users.
Environmental protection: At a time when environmental protection is increasingly emphasized, this fender shows a unique green value. Its tire chain mesh is made of waste tires, which realizes the recycling of waste tires and transforms waste tires, which may be a source of environmental pollution, into marine protection equipment components with practical value. By reducing the accumulation and improper disposal of waste tires, it effectively reduces the potential risk of waste tires contaminating environmental elements such as soil, water and air. At the same time, it also opens up a new path of sustainable development for the field of maritime protection, actively practicing the concept of environmental protection while meeting the needs of protection, and making a positive contribution to the construction of resource-saving and environmentally friendly maritime industrial ecology.
