How are car tires made?

Automobile tire manufacturing technology:

1, internal mixing process

Internal mixer is to mix carbon black, natural rubber or synthetic rubber, oil, additives, accelerators and other raw materials, and process them in the internal mixer to produce rubber compound. Some people describe this process as a kneading process when cooking.

2, rubber parts preparation process

In this link, it generally takes six steps to complete all the rubber semi-finished parts that make up the tire.

(1) Part 1: Extrusion

Add the rubber mixture to the extruder head to extrude different rubber semi-finished parts, such as tread, sidewall and triangular rubber strip.

(2) Workshop 2: Calender

The raw material cord passes through the calender, and a thin layer of rubber compound is hung on both sides of the cord, and finally it is processed into cord fabric. The raw material cord mainly uses nylon and polyester.

(3) Section 3: Weld Forming

Beads are made of many steel wires bonded and wound. This kind of compound for tire bead has some special properties. After vulcanization, rubber compounds and steel wires can be closely attached together.

Common sense of automobile tire beauty maintenance

In summer, we should not only pay more attention to the protection of car paint, but also pay attention to the use and maintenance of car tires. When inflating a tire, you must pay attention to cooling the tire first, so as to ensure accurate tire pressure. A beautiful car will remind the owner of 7 common sense of car tire beauty maintenance.

1, heat dissipation before expansion. After the vehicle stops, it must wait for the tire to dissipate heat before inflating, because when the vehicle is running, the tire temperature rises, which has an impact on the air pressure.

2. Pay attention to cleaning when inflating. The filled air cannot contain water and oil to prevent the rubber in the fetus from deteriorating and damaging.

3. Pay attention to safety when inflating. Check the air pressure with a barometer at any time to avoid puncture due to over-inflation.

4. Check the valve. If the valve and the valve core are not matched evenly, there are defects such as convex and concave phenomena, which brings inconvenience to inflation and air pressure measurement.

5. Check for air leakage. Before inflation, the dust on the valve should be wiped clean, and the valve core should not be loosened. After inflation, the valve should be coated with soap foam water to check whether there is air leakage.

6. Don't exceed the standard too much. When inflating, don't deflate after exceeding the standard, and don't inflate too much because you can't inflate for a long time. If it exceeds the standard, the cord will be stretched excessively, which will affect the service life of the tire.
