Summary

The video showcases the step-by-step process of recycling and vulcanizing used motorcycle tires. It begins by selecting suitable tires based on their structural integrity, especially the 'heel' area, ensuring no damage to the nylon cords. The host then demonstrates the removal of old tire treads using a specialized blade, followed by applying layers of new rubber (compounds). The vulcanization process is detailed, using heat and pressure in a PR machine to create new tread patterns. Finally, the host highlights the importance of precision in the process for durability, ensuring the recycled tire's safety and performance.

Takeaways

• 🛠️ The tire should be cooled down first before processing to prevent bloating and ensure safety during reprocessing.
• 🔍 The first step in tire recycling is selecting used tires that are still in good condition, focusing on the integrity of the internal structure and sidewalls.
• ✔️ Only tires with intact internal wires and no visible damage or nylon thread separation are deemed fit for recycling.
• 🔪 A modified ceramic cutting knife is used to manually scrape off old tire patterns, ensuring a smooth and uniform surface for further processing.
• ⚙️ Tires are reinforced using an inner tube called an airbag to preserve their structure while the old rubber is scraped off.
• 🧪 Tires are coated with a special adhesive after scraping, which must be allowed to dry completely before applying new rubber layers.
• 🧱 The process of layering involves applying multiple layers of new rubber, typically 2 mm thick per layer, to build up a total thickness of around 6 mm.
• 🛑 It's important to maintain the correct rubber thickness for durability, as both too thin or too thick layers may negatively impact the tire's performance.
• 🔧 Special care is taken to ensure precise application of rubber, particularly on the sides, as this affects both the appearance and safety of the tire.
• 🔥 The final step involves heating the tire at 160°C in a machine press for 25 minutes, using steam pressure to fuse the new rubber and create the desired tread pattern.

Q & A

What is the first step in the tire retreading (vulcanization) process?

The first step is selecting used tires that are suitable for retreading. The key factor is ensuring the internal structure, particularly the heel part, is intact without any nylon threads lifting or tearing.

Why is it important to cool the tire before processing?

Cooling the tire helps to minimize bloating and maintain its shape during the retreading process, ensuring that it can withstand the subsequent steps like scraping and vulcanization.

How do you determine if a tire is suitable for recycling?

A tire is suitable for recycling if the heel, the part that touches the rim, is completely intact without any damage or loose nylon threads. The thickness or thinness of the tire is less important than the condition of this specific part.

What tools are used to scrape off the old tire tread?

A modified ceramic cutting knife is attached to a grinder to scrape off the old tire tread. The scraping must be done carefully to avoid puncturing the tire.

Why is it necessary to use an airbag during the scraping process?

The airbag is inserted inside the tire to provide internal support and ensure the tire remains strong and intact during the scraping process, preventing the outer part from collapsing or tearing.

What is the purpose of applying glue to the tire before adding new rubber?

Glue is applied to the scraped tire to ensure that the new rubber (composite rubber) adheres properly. The glue needs to dry completely before the rubber is applied, to ensure a strong bond.

What is the thickness of the new rubber layer applied to the tire?

The new rubber layer is applied in two stages, with each layer being approximately 2 mm thick. The final thickness after the second layer is about 6 mm.

Why is precision important when applying the rubber layers?

Precision is crucial to ensure that the tire maintains its shape and performs correctly. If the rubber is too thick or too thin, the tire could have issues with performance and durability.

How does the vulcanization machine work to form the tire’s new tread?

The vulcanization machine uses heat (around 160°C) and pressure to mold the new rubber layer to the tire. The airbag inside the tire helps apply uniform pressure, while the heat ensures the rubber fuses to the tire, creating a durable new tread.

What final checks are done to ensure the tire is ready for use after vulcanization?

After vulcanization, the tire is cooled and checked for any defects, such as tears or loose nylon threads. The inner and outer parts are inspected to ensure the tire is fully intact and ready for safe use.
