Manufacturing standards for rubber fenders
The current industry standards for Rubber Fenders are "HG/T 2866-2016 Rubber Fenders" and "GB/T 21537-2008 Cone Rubber Fenders".
Types of rubber fenders
At present, there are many types of rubber fenders on the market. Rubber fenders mainly include buckling type, inflatable type, laterally loaded cylindrical type (drum type), butt V type (ie X type) and flexible pile type. When designing and producing rubber fenders, rubber fender manufacturers should consider the reaction force acting on the hull and the docking members of the dock, the deformation size of the rubber fender fender after absorbing the kinetic energy of the ship, the reaction force acting on the hull caused by the deformation of the fender, The relative stiffness of the rubber fender, the effectiveness of the fender's energy absorption during non-positive berthing, the rate at which the fender decelerates the ship's berthing speed,
There are many factors such as the coefficient of friction between the fender system and the hull, the capital investment and maintenance costs of the rubber fender system and supporting members, and the contact method between the rubber fender hull and the fender. Rubber fender users can choose different types of rubber fenders according to the actual situation. Except for tugboats and small ships, large-tonnage ships with rubber fenders are generally not equipped with rubber fenders. When berthing, they mainly use inflatable rubber fenders and rubber fenders. Protects the dock and rubber fender hull.
Application and characteristics of rubber fenders
Rubber fenders have the characteristics of good elasticity, high energy absorption, convenient maintenance, long service life and easy mass production. Inflatable fenders are widely used in buffering and protection of ships, offshore equipment, marine pipelines, ports, and yachts when they are docked.
When the rubber fender product is molded, it is impossible to remove the cohesive force of the elastomer after pressing with a large pressure, and when demolding, there is a tendency to be unstable. It takes time to stabilize and stabilize. Therefore, when designing a rubber product in the first place, regardless of the formulation or mold, the goodness of the fit must be carefully calculated, otherwise the product size may be unstable, which will lead to a decline in product quality.
How to store rubber fenders
When storing rubber fender products, avoid direct sunlight, avoid rain and snow, and avoid contact with acids, alkalis, oils, organic solvents and other substances; 1 meter away from the heat source, the storage temperature of rubber fenders should be kept at -15 ℃—40℃.
Rubber is hot melt thermoset, plastic is hot melt and cold set. Due to the different types of sulfides, the curing temperature of rubber also varies greatly due to climate change, room temperature and humidity. The reason why the quality may vary is that the production environment of rubber products is not adjusted at any time.
