Classification and structure composition of ship bolster

The ship vulcanized rubber ball is a kind of anti-collision equipment for compressed air. It is made of cord rubber pads, with compressed air inside which can float on the river surface as a defensive material. Therefore, when transferring and working on anchors, the ship's rubber fender is used as a key maintenance material to avoid hitting the ship. The ball can digest and absorb a lot of kinetic energy, and reduce the working pressure of the company on the ship's surface. This type of advantage has made the marine ball yard an idealized ship protector and is commonly used in large and medium-sized cargo ships, compressed natural gas ships, deep-sea service platforms, bulk carriers, wave structures, large and medium-sized ports, seaports and ports.

1. Classification of marine ball

　　According to ISO 17357:2002 <<Ship and Water Technology  High Pressure Floating Raft Pumping Vulcanized Rubber Relief Ball>> has the following classifications 1. The ball can be divided into:  a) Guard line cover type b) suspension type

2. Depending on the original gas pressure, the ball can be divided into:  a)  50 type (original gas pressure is 50KPa)  b)  80 type (original gas pressure is 80KPa)

3. The structural characteristics of the marine ball

　　The basic structure of the ship ball rest is composed of an outer vulcanized rubber layer, a cord-enhanced vulcanized rubber layer, and an inner vulcanized rubber layer. This is a cylindrical ball with hemispherical tension at both ends.

4. Marine rubber vulcanized outside the ball

　　The outer vulcanized rubber layer covers the outside of the rubber fender to maintain the cord and the inner vulcanized rubber layer to prevent damage and the impact of external energy. Such chemicals have strong tensile strength and tearing compressive strength, and can be applied in all weather conditions and difficult standards. The standard color is gray and black, but other colors such as dark gray and milky white can also be shown according to regulations.
