TIRE INNER LINER LASER CLEANING
As a "green" cleaning process, laser cleaning technology has a good application in the production and manufacturing of silent tires. It uses a focused high-energy laser beam to irradiate the surface of organic polymer materials, causing physical and chemical changes on the surface of the material, thereby changing its properties. It can effectively improve the tire quality and production process, enhance the matching between the tire and the car body, and improve the overall performance of the vehicle. By coating the inner liner of the tire with a soft solid gel-like polymer composite material, it achieves explosion-proof, puncture-proof and leak-proof functions. At the same time, a layer of polyurethane sponge is pasted on the surface of the anti-leakage glue to achieve sound insulation, absorb cavity noise, and achieve a mute effect.
Laser cleaning can effectively remove the remaining release agent on the inner liner of the tire and improve the adhesion of the composite coating and polyurethane sponge. The cleaning process does not require consumables, will not cause damage to the tires, is highly efficient, has good consistency, and can achieve automated cleaning.
Evaluate samples by selecting pulsed laser equipment and developing a sound process flow. Surface tension values under different parameters were obtained through dyne pen testing. The results show that different process parameters (laser energy density, processing efficiency) will affect the surface tension of the tire inner liner. Therefore, it is necessary to develop reasonable process parameters for the production process of silent tires. After testing, laser cleaning is uniform and meets the requirements for substrate damage. After cleaning, the internal friction coefficient increases to >37mN/m, and the surface tension reaches 40dyne/cm.
Use a roughness meter to test the surface after laser treatment，laser treatment greatly increases surface roughness.
Observed under a magnification of 1000 times, it was found that a large number of small concave blocks were widely distributed in the laser irradiation area, and the particle size reached the micron level. When the laser irradiates the surface of the material, it will destroy the rubber chain structure, produce this irregular concave feature, and increase the surface roughness.
Using laser cleaning to clean the inner liner of the tire requires no consumables, no damage to the tire, fast cleaning speed, and good quality consistency. It can realize automatic cleaning and does not require traditional polishing for subsequent chip cleaning operations and subsequent air blowing wet cleaning and drying operations. Laser cleaning has no pollutant emissions and is ready to use, providing high-quality preparation for the subsequent bonding of silent tires, self-repairing tires, and self-testing tires.

High safety
Compared with the traditional tire cleaning equipment, the use of low cost, simple operation, easy maintenance, safety and reliability.
Machine Advantage
The tire inner liner laser cleaning machine has several advantages over traditional cleaning methods such as sandblasting, chemical cleaning, and manual cleaning.
1. Non-contact and non-abrasive. The laser beam directly illuminates the inner surface of the tire without physically contacting the inner liner of the tire. This eliminates the risk of rubber damage that can result from abrasive cleaning methods.
2. High precision and adjustable to clean specific areas of the inner liner. This allows for targeted cleaning of areas where contaminants are more likely to accumulate, such as the shoulder areas of tires.
3. Environmentally friendly. Unlike traditional cleaning methods, it does not use any chemicals or produce any waste. This reduces the environmental impact of tire production and maintenance.
Machine Application
Tire inner liner laser cleaning machines have been used by many major tire manufacturers around the world. It is widely used in the production process of new tires and the maintenance of old tires.
During the production of new tires, laser cleaning machines are used to remove release agents and other contaminants from the inner liner of molds. This ensures that the new tire has a clean and smooth inner surface, improving its quality and performance
In the maintenance of used tires, laser cleaning machines are used to remove accumulated contaminants on the inner liner of the tires. This buildup can cause tire imbalance, vibration and uneven wear, leading to safety risks on the road. By using a laser cleaning machine, built-up contaminants can be removed and the tires restored to their original condition. This improves tire safety, performance and longevity and reduces the number of tires that need to be replaced.
