Understand the tire retreading and retreading process (IV)

pre vulcanization process: the name of this process can be seen that the tread rubber used here is pre vulcanized by the tread rubber manufacturer through the mold in advance. The tire retreading factory selects the tread rubber with different patterns, widths and thicknesses, such as belt or ring, according to the needs, and pastes it on the prepared carcass for metallographic microscope, The effect after fitting must be linear and flat without wrinkles, and then put the prepared tire into the vulcanization tank for vulcanization

vulcanization: vulcanization is a process that closely combines the new tread compound with the prepared carcass. During the vulcanization process, the unvulcanized rubber gradually changes from a soft, sticky, stretchable material to a tough, durable tread with good driving and ground grip

in the process of mold vulcanization, when the unvulcanized rubber is bonded according to the specified size, the prepared carcass to be vulcanized is placed in the mold. When the mold is closed, the carcass is inflated to an appropriate pressure, and the expanded carcass presses the unvulcanized rubber on the mold to form a tread pattern, and then after a certain period of heating to achieve vulcanization

in the pre vulcanization process, the vulcanization work is achieved through the pressure generated by electricity, steam or high-temperature liquids such as oil in the vulcanization tank. After the prepared carcass is pasted with new tread rubber, it is put into the vulcanization tank. After a certain period of time, the bonding layer of buffer rubber can be vulcanized under the pressure and temperature of a certain new material with the characteristics of technology intensive, large R & D investment and high product added value, So that the tread rubber and the carcass are closely combined. Although the above description of the tire retreading process is too simple, as long as the average value is remembered, that is, whether the mold is vulcanized or pre vulcanized, the final result is that the retreaded tire has the same toughness and wear resistance as the original new tire

final inspection: the last step in the tire retreading process is the final inspection. At this stage, the tire retreading factory will carefully inspect all retreaded tires to ensure that the products returned to consumers are completely high-quality products

after the tire passes the inspection, it should be marked or labeled like a new tire

today's retreaded tires are produced by well-trained professionals in modern factories. In the process of tire retreading, professional retreading workers carefully implement strict process standards in every process, and the equipment for producing each tire can be traced back. Only high-quality carcass can be renovated

retreaded tires are safe and reliable.

retreaded tires are widely used in civil aviation, U.S. military aircraft, school buses and various emergency vehicles. Automobile transportation companies have basically relied on retreading tires and long-distance transportation. Through the simulation test in the laboratory and the actual use for many years in all places where new tires can be used, it has been proved that retreaded tires are as safe, reliable and durable as new tires

tire retreading is one of the best ways to save money.

a retreaded tire with qualified production and proper maintenance will have the same wear mileage as a new tire. In fact, the more expensive the original tire is, the cheaper it will be to retread the tire. Since many tires can be retreaded once or more, throwing away a flat tire without retreading will lose most of the value of the tire. Whether you are a private car owner or a team manager, retreading the tire is the most effective and economical way to replace the new tire

tyre retreading 3 short boards need to be supplemented and utilized urgently is the recycling of resources

because most tyres are made of synthetic rubber, a derivative of petroleum products. Therefore, tire retreading is the best way to save oil energy and reduce waste tire dump. Every purchase of a retreaded tire is a specific action for the cause of resource protection
