What is a wear resistant and waterproof fender board?
Wear resistant and waterproof fenders are protective panels installed on the edges of ships, docks, or water structures. It is mainly made of materials with high wear resistance and waterproof performance, such as ultra-high molecular weight polyethylene.
Advantages of wear resistant and waterproof fender board
Waterproof and anti-corrosion effectiveness. The tight material structure gives it excellent waterproof performance, which can prevent the intrusion of seawater. This not only protects the fender itself, but also avoids internal corrosion problems caused by moisture infiltration.
Buffer collision damage. The wear-resistant and waterproof fender has excellent impact resistance, which can effectively buffer the huge impact force generated between the ship and the dock during the process of docking at the dock.
Limitations of wear resistant and waterproof fender board
High temperature performance limitation. The performance of wear-resistant and waterproof fenders will be affected in high temperature environments. For example, fenders made mainly of ultra-high molecular weight polyethylene have excellent performance at room temperature, but when the temperature rises to a certain level (such as approaching its melting point), the material will become soft, and its strength and hardness will decrease.
Material aging problem. Prolonged exposure to environmental factors such as ultraviolet radiation, oxygen, and chemicals can cause material aging in fenders. Ultraviolet radiation can cause the molecular chains of materials to break, leading to brittleness and reduced strength.
The main function of wear resistant and waterproof fender board
The wear-resistant and waterproof fender mainly has buffering protection, wear-resistant protection, and waterproof and anti-corrosion functions. It can buffer the impact force and prevent collision damage when ships dock, with excellent wear resistance to resist friction and prolong service life. It can also prevent seawater infiltration and resist corrosion, providing effective protection for ships and docks.
The working principle of wear resistant and waterproof fender board
Wear resistant and waterproof fenders absorb impact force and disperse energy through the deformation of high elastic materials; Its hardness and toughness balance, as well as self-lubricating properties, achieve wear resistance; The dense structure of the material gives it waterproof performance, thereby protecting ships and docks.
There are various types of wear resistant and waterproof fender board, how to choose the one that suits you
一、Consider the usage environment
1.Marine environmental factors. If used in high salt and highly corrosive marine environments, it is necessary to choose fenders that are resistant to seawater corrosion. For example, ultra-high molecular weight polyethylene (UHMWPE) fenders have good resistance to seawater and can resist the corrosion of chloride ions in seawater.
2.Temperature condition influence. For fenders used in areas with significant temperature changes, the temperature adaptability of the material needs to be considered. In cold regions, such as port facilities near polar regions, it is important to ensure that the protective fenders do not become brittle at low temperatures. Polyurethane fenders with good low-temperature toughness are a good choice.
二、Select based on protection requirements
1.Buffer performance requirements. If the vessel is berthed at a fast speed and has a high impact force, it is necessary to focus on the buffering performance of the fender. For example, for docks where large oil tankers or container ships dock, it is crucial to choose fenders with efficient buffering systems.
2.Consideration of wear resistance. In areas with frequent ship activities and high friction, such as the loading and unloading areas of commercial docks, high wear resistant fenders are required. Special surface treatment can be chosen, such as adding wear-resistant coatings or using wear-resistant material composite fenders.
三、Pay attention to installation and maintenance convenience
1.Installation method matching. Different docks and ship structures have different requirements for the installation method of fenders. If installing fenders on existing dock facilities, it is necessary to choose products that match the installation method with the existing structure.
2.Maintenance difficulty and cost. Consider the maintenance difficulty and cost of the fender during use. Choosing fender panels that are easy to clean, inspect, and repair can reduce long-term maintenance costs.
四、Consider cost-effectiveness
1.Initial investment cost. In the case of limited budget, the initial purchase cost of fenders should be comprehensively considered. The prices of fenders with different materials, performance, and brands vary greatly. For example, high-performance composite fenders may be more expensive, but they may have advantages in terms of protective performance and service life.
2.Long term cost-effectiveness. In addition to initial costs, long-term cost factors such as the service life and maintenance costs of fenders should also be considered. Although some fenders have a high initial price, if they have a long service life and simple maintenance, they may be more economical in the long run.
