The roles of black silicon carbide as filler in production of rubber roller
First questions,what is rubber roller?
Rubber roller is mainly made of three parts:roller core,rubber cover and bonding layer
Roller Core:
The rigid inner structure, often made of steel, aluminum, or other alloys, providing structural strength.
Rubber Cover:
The outer layer of elastomer that makes contact with the material being processed, providing grip, cushioning, and resistance.
Bonding Layer:
A crucial intermediary layer that ensures strong adhesion between the core and the rubber cover.
Our black silicon carbide is used in Rubber cover as filler
Then the second question is coming,what are the roles of black silicon carbide as filler in rubber cover during producing rubber roller?
Enhanced Rubber Roller Wear Resistance
Black silicon carbide has a Mohs hardness of 9.2, second only to diamond, significantly reducing the wear rate of rubber roller surfaces. For example, in sealing sleeve applications, its wear resistance can extend the service life by more than three times that of traditional metal materials.
Improved Rubber Roller High-Temperature and Thermal Shock Resistance
Black silicon carbide maintains 80% of its room-temperature strength at 1400°C and has a low coefficient of thermal expansion (4.5×10⁻⁶/°C). It can withstand temperature fluctuations of 500°C/min, preventing deformation or cracking of rubber rollers due to high temperatures.
Improved Rubber Roller Chemical Stability
It is inert to corrosive substances such as iron oxide slag, acids, and alkalis, preventing performance degradation of rubber rollers due to chemical attack in industrial environments. Improved Thermal Conductivity and Mechanical Strength of Rubber Rollers
High thermal conductivity (120 W/m·K) facilitates rapid heat dissipation, while high toughness (flexural strength ≥450 MPa) withstands mechanical loads, ensuring dimensional stability of the rollers under high-pressure conditions.
Cost-Effectiveness
Compared to metal materials, black carbide silicone rollers offer lower overall costs and longer maintenance cycles, offering an outstanding cost-effectiveness ratio.
In summary, thanks to its multi-dimensional performance improvements, black silicon carbide has become a key material in rubber roller production, particularly suitable for high-temperature, high-wear, and corrosive environments.
Haixu Abrasives Factory routinely produces black silicon carbide grit sizes.
