There are vulcanization processes that include crosslinking reactions by adding sulfur into raw materials (raw rubber, etc.) to increase elasticity. In this process, a carbon/sulfur analyzer is used to accurately control the amount of sulfur added. In addition, steel cords are used as reinforcement for tires. In research and development or quality control of steel cords, carbon concentrations need to be measured to control the mechanical strength.
Carbon & Sulfur concentration can be accurately measured: both steel cords and the nonconductive rubber with one unit!
| Sample weight [g] | Sulfer [mass%] | |
|---|---|---|
| Vulcanized Rubber: Granular sample A＊ | 0.0574 | 1.23 |
| 0.0499 | 1.26 | |
| Vulcanized Rubber: Granular sample B＊ ＊Depends on the homogeneity of the sample. | 0.0520 | 0.508 |
| 0.0573 | 0.486 |
| Sample weight [g] | Carbon [mass%] | |
|---|---|---|
| Steel Cord: Sample A | 0.1123 | 0.888 |
| 0.1455 | 0.893 |
Sulfur in granular rubber can be measured accurately and quickly in a wide concentration range. EMIA is also active for use in inspection lines and research and development applications. Although rubber is nonconductive, EMIA can measure independent of the conductivity of the sample because of the combustion method, satisfying the customer.
