The little "fetal hair" on the tires contains ten secrets that you don't know.

[Abstract]:

The tire mold has a lot of small holes for discharging the gas generated during tire molding. After the tire is molded and cooled in the mold, part of the rubber is left in the vent hole of the mold, and the tire is taken out from the mold and then in the vent hole. The rubber compound forms the tires that you see attached to the surface of the tire.
1. How is the tire hair produced?
 
The tire mold has a lot of small holes for discharging the gas generated during tire molding. After the tire is molded and cooled in the mold, part of the rubber is left in the vent hole of the mold, and the tire is taken out from the mold and then in the vent hole. The rubber compound forms the tires that you see attached to the surface of the tire.
 
2, the baby hair can check the quality of the tire
 
This is theoretically possible. By pulling the tire hair, it can be used to test the quality of the tire rubber. It can be elongated and it is difficult to pull off the surface. Rubber is better, and vice versa, the quality of the rubber is poor or expired. But you can't rely solely on this to judge the pros and cons of tire rubber. The amount of the baby's hair does not affect the quality of the tire, nor can it judge the quality of the tire with the amount of the tire.
 
3, all tires have a baby hair
 
All tires will produce lanugo in the production process. However, nowadays the more advanced tire factory has solved the problem of lanugo. In order to be beautiful, the procedure of removing the lanugo has been added. Some tire manufacturers have not gone to the lanuity to save costs, but There is no impact on the use of the tire.
 
 
4, you can use the tire hair to identify the new and old tires
 
As long as the tires are not used for the tire removal procedure, experienced people can use the tire hair to identify the newness of the tires, but this can not be distinguished by the presence or absence of the tires. Some tires have been treated with depilation, and some have even For a long time, it still exists well, and the tires are already old tires.
 
5, tire tires affect driving safety
 
This can be said to be 100% irresponsible. Please feel free to open the car with the tires.
 
6. Will the lanugo increase the dryness of the fetus?
 
This is not the case, the tire dryness is mainly due to the high-speed driving of the tire, the tire rotates at high speed, the air in the tire pattern is squeezed, and then released, this continuous "press release" will produce noise. . The faster the speed, the heavier the body, the greater the noise. In this high-speed rotation, the role of the tire hair is almost negligible.
