How to Make the child?

The tires on the car, like in the shoes of the people. As the saying goes, "barefoot is not afraid of the shoes," Keren if I do not wear shoes, sure step. Similarly, if the vehicle does not have a few large "shoes", can not walk safely on the road in broad. In addition to a pair of good shoes to look beautiful, but also good durability and comfort to the achievements of the perfect walking experience, which requires high-quality materials, sophisticated technology and rigorous process as necessary. Doing a good pair of shoes like this, not to mention the integration of the rubber industry, chemical industry and machine building industry and other sectors of the essence of advanced technology and the manufacture of tires. All along, the tire manufacturing process are not known to the public. International tire giant Pirelli in China's first official car tire plant into operation, so I have the chance to witness the mysterious tire production process, as we seek to hide the car in the "shoes" the true story behind.

Rubber extrusion

The tire "appearance" It's hard to make people think of their initial shape is long and wide rubber band. Rubber is carbon black, natural or synthetic rubber, raw materials, such as additives mixed into the mixing process. As a tire manufacturing process, the main object and vector processing, rubber rubber in the proportion is usually reached about half that, in order to make the rubber with the necessary characteristics, but also to be added, such as enhancer, adhesives, anti-aging agent , And other chemical substances in order to change the strength of rubber, plastic, flexibility, durability, and other physical properties. Tires on all semi-finished plastic components, such as the tread, sidewall and triangular strip are all in the follow-up of the manufacturing process for plastic materials processed from the raw materials. Rubber was fed through the machine to send out into the nose can be squeezed to meet the different needs of semi-finished plastic parts.

Ply calendar

Ply tire is the skeleton, to keep tires on the shape and size with a very significant role. The main cord cord rayon and nylon cord are rayon of greater strength and flexibility, it can be used to make rayon tire of the same size increase the load capacity; with rayon, nylon cord in durability Better performance. At present, most of the vehicles have been used radial tire, the ply cord arranged in the direction of meridian tires with the same section, so arranged so that the cord can be utilized to the full intensity, the cord may also rise by 40% to 50% And improved thermal performance tires. Cord through the calendar and close fitting rubber, constitute ply tire.

Tire molding

Tire production needs of all semi-finished products in the machine was assembled in fetal Health. At this time of the birth of Health from the initial appearance has been with the shape and size tires, but also the internal structure needs to be further processed. In the assembly before the birth of Health, and ply tire belt has been in accordance with the specifications of tire design and structure of the need to be applied to cutting into the length and width of the access and good connections.

Health vulcanized tire as a whole

All in rubber after a long period of use after the consumption of rubber aging deterioration will occur, and even the cracks on the surface, the tire is no exception. Rubber is the chemical composition of polyisoprene, it will become a higher temperature viscous, when it will harden in the cold become brittle. If the rubber by the long-term air, the role of sunlight, it will be a gradual oxidation and aging occurs. In order to ensure the tires in the roads and changeable weather conditions, the period in life has always been able to maintain its comfort, durability and physical and chemical properties do not change the need for the Sulfide Health births overall. Add raw fetal-specific vulcanizer of the die, to die in charge of sulfur into the vapor, so that the child of Health and sulfur steam full contact, through the vulcanization of rubber in-house response to changes in the molecular structure so that the antioxidant properties of rubber significantly improved significantly To extend the service life of the tire. In addition, the Health births in the curing mold, is also inscribed with the appearance of the finished tire, design, fonts, as well as tread pattern. At this point the car "shoes" as if covered with a beautiful coat from the final set foot on the road not far has been a sacred moment.

Final test

And pairs of shoes in every shipment before the city into a test of qualified small piece of paper, any tires in a factory before to go through rigorous testing to ensure its physical and chemical properties to achieve the national standard. Detection of uniformity in the uniform of the completion of the experimental aircraft, by simulating the normal rotation of the tires to measure the radial tire, as well as fluctuations in the lateral force. After the tire to go through X-ray examinations, which observed in the processing of rubber does porosity, have trachoma. After passing all tests of the finished tire can be sent to Cheng Pinku preparation of the shipments.

The tire manufacturing process embodies the scientific and technological strength, wisdom, as an important component of auto parts, tires and the bad quality of the performance of Liang You, the reliability of stringent processes have a direct impact on traffic of comfort and stability And security. Manufacturing is a branch of learning tire, the tire selection is also a branch of learning, only for the car to select a suitable pair of "shoes", your car can run faster and more stable, more secure. At the same time, to extend the vehicle out of "shoes" of life, in addition to maintaining proper tire pressure, driving the best time to choose a flat road, to avoid prolonged eliminate injustice in the road, but also to avoid the attention of a number of Stone and covers the process, because even a small protruding material could stab tires.
