Cutting off the damage portion Sticking two pieces of wood to get a stable surface for better working Beginning of Buffing Process Tyres has the old tread mechanically removed on high-speed buffers. Buffers are extremely accurate and will remove the proper amount of old rubber while truing the Tyre to an exact specified diameter and radius. The primary objective of buffing is to remove the worn-out tread and prepare the surface for a new tread. Cleaning the damaged area properly to remove any dirt, dust or other particles A uniform layer of Black vulcanizing cement is applied on the inner
and outer surface of the Tyre, the black vulcanizing cement is then allowed to dry 45 minutes at room temperature. Begin to apply the patch by first removing the foil backing from the rubber. Center the patch directly over the injury site. pressing the patch down on the tube using finger pressure to make sure there is good contact. Using the tire stitcher, pressing down firmly on the patch Turning a Tyre to work on inner surface of damaged area Applying patches for inner reinforcement. using finger pressure to make sure there is good contact. Using the Tyre stitcher, pressing
down firmly on the patch Stitching in this manner removes any air that may be trapped underneath the patch. Tyre then turned again to work on outer surface Trimming off the loose rubber and old tread around the damaged area Filling out the cut with rubber from outside of
again to work on inside The same process of adding new rubber and stitching repeated several times Over the damaged area inside the inner wall of the Tyre Tyre vulcanization is the process of adding new raw rubber to a damaged area of a Tyre to create a repair suitable for the rest of the Tyres Road life damaged Tyre will be prepared, and new rubber molded into the damaged area Vulcanization gives rubber its characteristic elastic quality. This process is carried out by mixing the latex with Sulphur other vulcanizing agents such as selenium and tellurium are occasionally used
but Sulphur is the most common ingredient in Vulcanizing process Charles Goodyear invented the vulcanization process in the mid-1880s while doing experiments to improve Tyre tubes Although this process received heavy criticism in the beginning people eventually came to appreciate the benefits of … vulcanization in the manufacturing and repair of Tyres After adding the desired amount of rubber layers, the supporting woods are removed and Tyre turns again for the final touches at front surface Some more stitching and rubber applied to make sure of strength and durability After which the extra layer of rubber is cut off from
the outer wall of the Tyre The tire is then taken to the vulcanizing machine Here, bags filled with sand are placed inside the tire with a coating of liquid soap Then wood pieces are also placed along with the bag to maintain the desired pressure and resistance in the vulcanizing machine. Then the Vulcanization chemical process is begun in which the rubber is heated with Sulphur, accelerator and activator at 140–160°C. The process involves the formation of cross-links between long rubber molecules so as to achieve improved elasticity, resilience, tensile strength viscosity, hardness and weather resistance. It took three
to four hours to complete the vulcanizing process. After three hours the Tyre is removed from the machine Then sandbags and pieces of wood placed inside the tire are removed Then after thorough testing and satisfaction, the process of vulcanizing the tire is completed, vulcanizing a tire is an excellent way to repair and strengthen your tire since vulcanized rubber lasts a lot longer than natural rubber. In fact, vulcanized rubber becomes ten times stronger than natural rubber due to the cross-linking of sulfur and other metallic oxides with the rubber. Thank you for watching, See in next video 🙂
