The core function of adding nitrogen input in industrial ovens is to create an inert atmosphere environment with low oxygen or no oxygen. This is usually referred to as "nitrogen protection" or "nitrogen-filled baking".
Preventing oxidation is the most common and primary purpose. When heated in the air (with an oxygen content of approximately 21%), many materials will undergo oxidation reactions, thereby affecting product quality. Adding nitrogen input to industrial ovens can prevent the formation of oxide scale (such as rust) on the surface of metal products during heating, keep the metal bright and clean, and improve the quality of subsequent processes such as electroplating and spraying. Or to prevent the oxidation of component pins, pads and precision films at high temperatures, ensuring the quality of soldering and the long-term reliability of the product. At the same time, it can also prevent chemical and powder materials from undergoing chemical reactions with oxygen at high temperatures, thereby altering their chemical properties.
2. Some materials pose a risk of fire or explosion in high-temperature and oxygen-rich environments. Increasing nitrogen input can suppress combustion and explosion.
In industries such as printing and coating, a large amount of flammable organic solvents (such as alcohol, acetone, and toluene) are volatilized during the baking process. Introducing nitrogen to reduce the oxygen concentration below the limit oxygen concentration can completely eliminate the risk of fire and explosion, which is an important safety measure. For metal and plastic powders, when they reach a certain concentration in the air, they are highly prone to explosion when exposed to open flames or high temperatures. Nitrogen protection can create a safe processing environment.
3. Improve process control and product quality. Heating in an oxygen-free or low-oxygen environment can avoid many side reactions caused by oxygen. In processes such as chip manufacturing and solar cell production, extremely high cleanliness and an oxygen-free environment are essential to prevent the oxidation of silicon wafers, metal electrodes, etc., ensuring extremely high product yield and performance.
4. While filling the oven with nitrogen, the air that originally contained moisture and oxygen inside the oven will also be "driven out". This not only prevents oxidation but also plays an auxiliary drying role, making it particularly suitable for products that are extremely sensitive to moisture.
In conclusion, adding nitrogen input to industrial ovens is to actively control the heating environment rather than passively heating in the air. This is an important technical means used in high-end manufacturing and precision processing.
