Carbon black is an important tire filler that can improve the performance of tires in terms of wear, durability, aging resistance and heat resistance. The impact of the proportion of carbon black usage on the service life of tires is a complex issue that requires consideration of multiple factors.
1.Types of carbon black.
There are many types of carbon black, such as carbon black, graphite black, activated carbon, etc. Their chemical properties, physical properties, shape, particle size, etc. are different, and their impact on the service life of tires will also be different.
2.Proportion of carbon black usage.
The proportion of carbon black in the tire to the weight of the whole tire is different, and too high or too low carbon black will affect the service life of the tire.
3.Dispersion of carbon black.
The dispersibility of carbon black refers to whether the carbon black can be evenly dispersed in the tire. If the carbon black is unevenly dispersed, it is easy to cause uneven surface hardness of the tire, and the wear will be uneven, which will affect the service life.
4.Conditions of use of tires.
Tires are used under different road conditions, climate, temperature, speed and other conditions, these factors will also affect the service life of tires, and the proportion of carbon black is only one of the factors.
5.The load of the tire.
The load of the tire refers to the weight carried by the tire, and the load of the tire is too large or too small will affect the service life of the carbon black. If the load is too large, the tire is easy to be damaged, and if the load is too small, the tire is easy to wear out, and the performance of carbon black cannot be fully utilized, thus reducing the service life of the tire.
The proportion of carbon black dosage has many effects on the service life of tires, and the service life of tires cannot be judged only by the proportion of carbon black dosage. In order to prolong the service life of tires, it is necessary to select the appropriate carbon black type and amount according to different use conditions and loads, and at the same time ensure the dispersion of carbon black and the maintenance of tires.
