Production inspection of marine rubber fenders
- 2020-03-06-


Port marine non-slip rubber fenders can be divided into two categories based on 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-filled rubber fenders and filled rubber fenders according to the difference in the internal buffer material.

Solid rubber fenders are anti-collision machines and equipment with a long history and extensive coverage of port vessels.

According to the pressure condition of the rubber fender, it can be divided into shear type, rotary type and reduced type.

According to the structure of rubber fenders, solid core rubber fenders can be further divided into drum-type rubber fenders, D-type, cone-shaped, fan-shaped, rectangular frame, and cylindrical rubber fenders.

The new items of professional inspection of rubber fender technology are:

Tensile strength

2. Fixed compressive strength

3.Extensibility of vulcanized rubber

4. Relative density / ratio


6. Lashen characteristics

7.Impact characteristics

8.Tear characteristics (Tear compressive strength test)

9. Reduction characteristics (reduction of permanent deformation)

10. Adhesive compressive strength and abrasion resistance (friction coefficient)

11. Ultra-low temperature characteristics

12. Water content

13. Gum water content

14. Measurement of liquid-resistant Mooney viscosity

15. Heat resistance

16. Cutting reliability

17.Vulcanized rubber curve

18. Characteristics of Mooney Scorch Time Vulcanized Rubber
