(Summary description)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: 1.Tensile strength 2.Compressive strength at constant extension 3.Extensibility of vulcanized rubber 4.Relative density/ratio 5.Intensity 6.​​Lashen characteristics 7.Impact characteristics 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 12.Moisture content 13.Glue water content 14.Measurement of liquid-resistant Mooney viscosity 15.Heat resistance 16.Cutting reliability 17.Vulcanized rubber graph 18.Mooney scorch time vulcanized rubber characteristics test
