What thickness of rubber sheet is suitable for rubberizing the drum

Rubber sheets are required for drum rubberizing. The thickness of rubber sheets comes in several specifications, such as 3/8, 10/12, 15/20mm, etc. Generally, people tend to believe that thicker rubber sheets will last longer. Although there are corresponding standards for the diameter of the drum and the thickness of the rubber sheet, people still prefer to use thicker rubber sheets for drum rubberizing.
For example, for drums with diameters within 320-800mm, a 10mm thick rubber plate is sufficient according to the standard. For those larger than 800mm, a 12-15mm rubber plate is recommended. Some people may still ask if it is okay to use a 15mm thick rubber plate when covering a 600mm drum?
The drum is covered with rubber sheets, which serve to prevent slipping and wear, protecting the metal surface of the drum from wear and corrosion. The wear resistance of the rubber sheets is naturally important. Thicker rubber sheets can indeed ensure longer wear resistance, but they also have greater tension. This is more pronounced for drums with smaller diameters. Even if pressure is applied during the rubber covering process and the covering is completed, there is still a high risk of the rubber sheets cracking or detaching during use.
Therefore, when it comes to roller rubber coating, it's not necessarily the thicker the rubber sheet, the better. A rubber sheet of appropriate thickness will suffice. The correspondence between roller diameter and rubber sheet thickness can be referred to as follows: diameter < 320mm = thickness 8mm; diameter 320-800mm = thickness 10mm; diameter > 800mm = thickness 12-15mm. When the thickness of the rubber sheet is fixed, to make the roller rubber coating more wear-resistant, choosing a higher quality rubber sheet is an option. For example, the RIT rubber sheet imported from Germany with a semi-vulcanized layer. The material of the CVUL rubber sheet is a natural rubber synthesized from BR/IR/SBR, with a wear resistance coefficient 2-4 times that of similar domestic rubber sheets. The rubber layer is flexible, with an elongation at break reaching 450%. The semi-vulcanized layer of the rubber sheet can also form a cold vulcanization reaction with cold vulcanization glue CV2000, integrating into one, with bonding strength equivalent to that of hot vulcanization.

The performance of CVUL rubber plates ensures that they can be used for 2-4 years under normal usage conditions and for 1 year in high-wear environments. For conveying materials that are highly abrasive, wet, muddy, or with high tensile strength belts, ceramic rubber plates are recommended. Ceramic rubber plates have stronger wear resistance, which can be 8-10 times that of traditional rubber plates. At the same time, ceramic rubber plates are only available in a thickness of 15mm, making them unsuitable for drums with too small a diameter.
