We all know that a lot of carbon black production is used in tire rubber, but few people know when rubber tires started to use carbon black. In fact, rubber tires were discovered much earlier than carbon black, which means that the previous There is no carbon black added to rubber tires. It was gradually used in rubber tires only after people discovered that carbon black has a reinforcing effect. Here I will take you to review the development history of carbon black and rubber tires, so as to tell you when carbon black was used in rubber tires?
when are rubber tires used
The earliest tires were made of wood or iron, which can be seen from ancient Chinese chariots and foreign gentlemen's carriages. Later, when the explorer Columbus, on his second exploration of the New World in 1493-1496, reached the island of Haiti in the West Indies, he was surprised to find a hard rubber block played by local children. Later, he brought this wonderful thing back to the motherland. After several years, rubber has been widely used, and the wheels have gradually changed from wood to hard rubber. That is to say, rubber tires that only appeared around 1500.
When is carbon black used
Carbon black was first produced in North America with natural gas in 1821. However, in 1912, it was discovered that carbon black had a reinforcing effect on rubber. Since then, carbon black has gradually become an indispensable raw material for the rubber industry. That is to say, carbon black was only used in rubber tires in 1912.
What is the effect of adding carbon black to rubber tires?
Carbon black used in rubber tires is divided into high wear-resistant, reinforced and semi-reinforced varieties. The role of adding carbon black to rubber tires is to increase the strength of the rubber and enhance the wear resistance, that is, adding carbon black to the rubber can increase the wear resistance of the tire and increase the strength. Without reinforced rubber, its strength is very low, and carbon black is a good reinforcing agent, which is why the tires of cars are all black.
