The non-slip rubber fenders for port ships can be divided into two categories according to the structural characteristics:solid rubber fenders and floating rubber fenders.
Floating rubber fenders can float freely on the river surface,and can be divided into:air-pumped rubber fenders and refillable rubber fenders according to the difference in the internal buffer material.
Solid core rubber fender is the earliest use in history and wide application coverage of port ship anti-collision machinery and equipment.
According to the compression condition of the rubber fender,it can be divided into shear type,rotating type and reduced type.
According to the structure of rubber fenders,solid port rubber fenders can be divided into drum rubber fenders,D-shaped,cone-shaped,fan-shaped,rectangular frame,and cylindrical rubber fenders.
New rubber fender technical inspection items include:
2.Compressive strength at constant extension
3.Extensibility of vulcanized rubber
8.Tearing characteristics(testing of tearing compressive strength)
9.Reducing characteristics(reducing permanent deformation)
10.Adhesive compressive strength and abrasion resistance(coefficient of friction)
11.Ultra-low temperature characteristics,resilience performance
13.Glue water content
14.Measurement of liquid-resistant Mooney viscosity
17.Vulcanized rubber graph
18.Mooney scorch time vulcanized rubber characteristics test
