The produced barium sulfide enters the leacher, and the temperature is controlled above 65°C to obtain a barium sulfide content of 70%, and then enters the clarification barrel, add zinc sulfate for reaction after clarification, control the zinc sulfate content to be greater than 28%, pH=8~9, and obtain a mixture of barium sulfate and zinc sulfide with a density of 1.296~1.357 g/cm3.

3. UV Protection Tires are constantly exposed to harsh environmental conditions, including ultraviolet (UV) rays from the sun. Titanium dioxide provides excellent UV protection, minimizing degradation caused by prolonged exposure. This property ensures that tires maintain their integrity and performance over time, leading to a longer lifespan.

ROS were detected through the colorimetric assay employing the nitro-blue tetrazolium salt (NBT salt) by reading the absorbance of the reduced blue molecule.
