The wheel can be said to be one of the most important inventions in human civilization. For a car, the wheel is also one of the most important parts, and the only part that comes into contact with the ground. The quality of the tire not only affects performance. It is also directly related to the driving safety of the vehicle.
However, in a colorful world, the color of car tires is only black, why?
We all know that the main raw material for car tires is rubber, and the original color of rubber is white, so when people first use rubber for pneumatic tires, it is also white.
It is said that practice is the only criterion for testing truth. It has been found that white tires have good wear resistance in practical use, and they are easy to oxidize and turn yellow after a long time, which affects the appearance.
In order to make the tires have a better service life and excellent wear resistance, engineers are constantly trying to add different 'auxiliaries' to the tires, which makes the color of the tires change with the color of the additives. When the engineers added carbon black materials to the tires, they found that their actual service life was 4 to 5 times higher than that of ordinary natural rubber white tires.
Since then, black tires have officially entered the stage of history, but in the 34s of the last century when black tires began to flourish, some rich and sought-after wealthy businessmen used white paint to paint the outer ring of the tire. White. We all know that the environment of the tires is very bad. It will take a long time for these white paints to crack and fall off. It is not as good as pure black tires, so this 'refit' is not popular for a long time. .
With the improvement of the craftsmanship, white rubber tires have recovered in the middle of the last century, but the overall performance is still difficult to join the black rubber tires of carbon black raw materials, so it is not too long to be 'cool cool'.
In the 1990s, Michelin used silica to replace the traditional carbon black, and added different dyes, so that the tires can maintain relatively good performance, but also have colorful colors. The wish is beautiful, the reality is Cruel, due to cost issues, and the color is too personality and other factors, and has not been recognized by manufacturers and consumers, and ultimately ended in 'cool cool'.
From the development of tires, the emergence of black tires is also a necessity. From the current manufacturing process, the production of colorful tires is not difficult for the tire production, but in terms of performance and cost performance, consumers Often, I still use my money to vote for black tires. So tire manufacturers can only produce pure black tires in order to pursue a longer life and better performance. This is why we have seen The reason why the tires are black.
In the future, the development of tires may be far beyond our imagination. At that time, there may be no inflatable tires, and the colors may be colorful.
