Why the wheels are dyed black?
As early as the nineteenth century, automotive rubber tires due to the different additives, the color is not fixed. By 1915, due to the use of carbon and hydrocarbon high temperature agglomeration process, rubber ink-like pure black, and wear resistance In the twentieth century, three decades, many foreign people have a car in order to show their wealth and social status, have the outer side of the tire brush on the white side of the tire. But the difference between this tire beauty method is the use of tires for some time, the paint will gradually peel off, sidewall mottled, very unsightly, this way is gradually being left to the 20th century, 601 Age, the use of white rubber white rubber tires see the recovery, but this tire strength and resistance to tearing poor performance, poor aging resistance, the cost is more expensive, use a little longer, the compound will slowly turn yellow Change brown, lose the original decorative effect
Because the black has four legs running fast
Now the production of tires and no name "black" the. It depends entirely on a brand new, incredible production process: the production of automotive tires in the rubber raw materials mixed with a certain amount of sand, reducing the proportion of carbon black. Of course, this is a special production process controlled by electronic technology and computer technology, and the sand is actually the basic raw material of silicon. Chemists put silicon into the rubber, so they can create "arbitrary" car tires. This kind of car tire is suitable for different needs, low temperature wheel and high temperature hard.
Because the tires contain carbon black. In fact, the world's first tire is milky white, like the color of natural rubber. At that time, the production of tire manufacturers also do not know the carbon black mixed in the rubber will have such a big role, can enhance the tire wear resistance and anti-skid performance.
