In the 19th century, a car tire was born at that time. He insisted on the nature of rubber-white; a single color usually cannot satisfy the diversified pursuit of car owners. We started to add a variety of different dyes to the tires, and the color of the tires began. The changes followed; in 1915, carbon black material was added to the tires, we suddenly discovered that after the participation of carbon black, the wear resistance of the tires was 4-5 times that of white tires; then black tires began to cover. The editor of the solid tire price list tells you why it is black? You may also think why the color of the tire can only be black? Can't it be white, pink, or rainbow? In fact, this question was more than a hundred years ago Some people have thought about it and practiced it vigorously, and the result is that we coincidentally choose black.
У деветнаестом веку рођена је аутомобилска гума. Инсистирао је на природи гумено-белог; једна боја обично не може да задовољи разноврсну потрагу власника аутомобила. Почели смо да додајемо различите боје и боје гума у гуме. Почетак је био променљив; 1915. гумама је додат материјал чађе, изненада смо открили да је отпорност гума на хабање након учешћа чађе 4-5 пута већа од белих гума; онда су почеле црне гуме.
In the 1950s, in order to flaunt their dignity and prominence, the rich and powerful people once again set their sights on the tires. This time more directly, they used rough paint to scrub the tires, washing and brushing, and the colors can be brushed out. Now! XX paint shouts "rewrite the day" every day, dare to be creative from the tires washed in the last century? But this kind of decent project is easy to fail, and after a long time, the paint is easy to fall off and spotty It was very unsightly, and this method was gradually abandoned. In the 1960s, white tires made a comeback. Although improvements were made, their functions were not greatly improved. On the contrary, the cost soared. What is even more unbearable is that after a long period of time, the color of white tires became brown and yellow, so they gradually declined.
Касније, 1980-их, у просперитетним земљама појавиле су се гуме са белим словима или белим бочним појасевима, а неке компаније су чак развиле и провидне гуме, али оне су имале мало практичног значења. Са напредном технологијом, силицијум диоксид је заменио чађу, а шарене гуме су поново наоштрене. Овог пута вештине су софистицираније, али тржиште још увек није на високом нивоу.
