Nitrogen and oxygen generators play a critical role in the rubber tire manufacturing industry, where they provide essential gases for various processes that enhance product quality, increase efficiency, and ensure workplace safety. Here are some specific applications of nitrogen and oxygen generators in the production of rubber tires:
- Protective Atmospheres: Nitrogen is used to create protective atmospheres during the curing process of rubber compounds. The inert gas environment prevents the rubber from coming into contact with oxygen, which can lead to oxidation and deterioration of the material. This ensures that the rubber maintains its desired properties and extends the lifespan of the final product.
- Purging: Nitrogen is utilized to purge mixing equipment before the addition of raw materials, removing air and moisture to prevent contamination that could affect the consistency and quality of the rubber mixture.
- Extruder Cooling: Nitrogen can be used as a cooling medium for rubber extruders, providing a clean and inert option compared to water or oil, which can leave residues on the rubber. This helps maintain the quality of the extruded rubber and prevents the formation of defects.
- Inerting: Nitrogen is used to inert storage silos and transport systems for rubber granules or powders, eliminating the risk of dust explosions and fires. This is particularly important during the handling and blending of rubber compounds.
- Forming Gas Atmospheres: Nitrogen mixed with a small percentage of hydrogen is used to create a forming gas atmosphere for certain rubber processing steps. This reducing environment protects against oxidation at high temperatures and improves the quality of the finished product.
- Tire Curing: Nitrogen can be used in tire curing processes, where it helps to evenly distribute heat and pressure, ensuring consistent curing and improving the tire’s performance and durability.
- Oxygen Monitoring: While not directly using oxygen, monitoring oxygen levels is essential in rubber manufacturing to ensure that the environment remains controlled and free from excessive oxygen that could lead to oxidation or other adverse effects on the rubber compounds.
The use of onsite nitrogen and oxygen generation provides tire manufacturers with a reliable and economical source of these gases, ensuring uninterrupted supply and high purity levels that are critical for maintaining the quality and consistency of rubber products. Additionally, onsite generation eliminates the risks associated with storing and transporting compressed gas cylinders, enhancing overall plant safety and reducing operational costs.
