Ultra-high molecular weight polyethylene dock fenders have the characteristics of lightweight, impact resistance, wear resistance, corrosion resistance, UV resistance, aging resistance, small friction coefficient, and can effectively prevent ultraviolet radiation and so on. Its impact strength is 20 times that of polyvinyl chloride, 10 times that of nylon 66, and 8 times that of polytetrafluoroethylene. It has wide applicability and can be used as a ship anti-collision device. Strong adaptability to ship berthing; easy installation and maintenance.
1. Basic characteristics of ultra-high molecular weight polyethylene materials
Ultra-high molecular weight polyethylene (UHMW-PE) material is a thermoplastic engineering plastic with a molecular weight of more than 2.5 million. Compared with ordinary polyethylene, due to its huge molecular weight, it has the following special properties.
Excellent wear resistance: ultra-high molecular weight polyethylene material has extraordinary wear resistance. Under certain conditions, its wear resistance is 7 times that of carbon steel, 27 times that of brass, 5 times that of nylon 66 and polytetrachloroethylene, and 10 times that of hard PVC.
Excellent impact resistance: Ultra-high molecular weight polyethylene material not only has good wear resistance but also has high impact resistance. Its impact strength is greater than 140 kg/cm.
Good self-lubrication: the friction coefficient of ultra-high molecular weight polyethylene material is 0. 07 ~ 0. 11. After being used as the liner of the closing hopper under the coal bunker, it will basically not stick to the bunker and block holes.
Excellent corrosion resistance: UHMWPE material has excellent corrosion resistance. Except for a few strong oxidants, it can resist the corrosion of various chemical substances, such as acids, alkalis, salts, etc.; it will not cause electrochemical corrosion, and it is also very good for various oil stains and harsh environments (except for ambient temperatures exceeding 90°C). adaptability.
Very small water absorption: The water absorption of the ultra-high molecular weight polyethylene material used as the lining board of the lower closing hopper of the coal bunker is less than 0.1%.
2. Advantages of pier fenders
The fender veneer provides a new type of fender with veneer, which can solve the problem that the veneer is easy to fall off and the fender product is damaged in the prior art. The utility model relates to a fender with a veneer, which includes a fender body and a veneer, the fender body is made of rubber, and the veneer and the fender body are bonded together through special rubber vulcanization. The veneer panel of the utility model is fixed on the fender body by chemical cross-linking, replacing physical connection methods such as bolts, with strong binding force, and it is not easy for the veneer panel to fall off. It is safe and reliable and is more suitable for environments such as small docks and inland waterways. Use: The friction coefficient of ultra-high molecular weight polyethylene board is used to significantly reduce the friction coefficient of the veneer, which effectively improves the service life of the fender and ensures the berthing safety of the hull.
UHMWPE is the material of choice for steel fenders and other heavy-duty applications. It combines extremely low friction, excellent impact strength, and wear resistance far superior to steel. Has higher durability. The standard color is black, but if other colors are required, there are yellow, white, gray, blue, green, and red. The UHMW-PE material is compounded to resist ozone and ultraviolet radiation. They won't degrade or rot and are easy to recycle at the end of their useful life. UHMWPE fenders are simple, modular in design, low coefficient of friction, a non-marking surface, reduce hull pressure, and easy maintenance.
Ultra-high molecular weight polyethylene fenders have a long service life, strong corrosion resistance, strong toughness, and elastic strength at low temperatures, relatively strong corrosion resistance, and can resist most acids, alkalis, organic solutions, and hot water erosion. Low water absorption, low water vapor permeability, low coefficient of friction, strong stretchability; easy to process, convenient processing, on-demand customized quality, and trustworthy. UHMW-PE fender veneer and guard sill are one of the products researched and developed by our company for port and wharf applications. The Port fender ultra-high molecular weight polyethylene UHMWPE baffle has lightweight. Impact resistance, corrosion resistance, UV resistance, aging resistance, and small friction coefficient, can effectively prevent the impact of ultraviolet radiation and hull impact on the hull and dock.
