What is the effect of adding carbon black to rubber tires?
Carbon black used in rubber tires is also divided into high wear resistant, reinforced, and semi reinforced varieties. The role of adding carbon black to rubber tires is to increase the strength and wear resistance of the rubber. That is, adding carbon black to the rubber can increase the wear resistance and strength of the tire. Without reinforced rubber, its strength is very low, and carbon black is a good reinforcing agent, which is why car tires are black.
When were rubber tires used?
The earliest tires were made of wood or iron, as can be seen from ancient Chinese chariots and foreign gentleman carriages. Later, when the explorer Columbus, during his second exploration of the New World to the island of Haiti in the West Indies in 1493-1496, he was surprised to find a hard rubber block played by local children. Later, he brought this wonderful thing back to his motherland. A few years later, rubber was widely used, and the wheels were gradually made of hard rubber instead of wood. That is to say, rubber tires only appeared around 1500.
When was carbon black used
"Carbon black was first produced from natural gas in North America in 1821. However, in 1912, it was discovered that carbon black had a reinforcing effect on rubber, and since then, carbon black has gradually become an indispensable raw material for the rubber industry.". That is to say, carbon black was only used on rubber tires in 1912.
