SemSong Anti-Oxidation Nitrogen Gas Cabinet is a commonly used equipment in the storage of semiconductor, metal components and other materials. Its core function is to prevent oxidation. By using liquid nitrogen or highly concentrated nitrogen gas tanks, the nitrogen gas tank can effectively create a low-humidity environment, not only achieving the effect of preventing oxidation, but also in some special situations, such as the preservation of material components, it can play the function of moisture protection. The working principle of the nitrogen gas tank mainly relies on the nitrogen filling technology. Through the pressure of the nitrogen source, nitrogen is forcibly filled into the tank, and by using the replacement and neutralization methods, the oxygen content in the tank is gradually reduced, thereby achieving the goal of oxygen-free anti-oxidation. Generally, when the nitrogen concentration in the tank reaches above 95%, it can be considered that this nitrogen gas tank has an excellent anti-oxidation effect.
Selection and Use of Nitrogen Cabinet
When choosing a nitrogen tank, several key factors deserve our attention: the control of nitrogen flow rate, real-time monitoring of nitrogen concentration, the stability of the nitrogen control system, the scalability of the equipment, and the completeness of anti-static measures. The consideration of these factors will directly affect the performance and safety of the nitrogen tank.
The control of nitrogen gas flow is of vital importance as it directly affects the working efficiency of the nitrogen tank. A high flow rate of nitrogen can quickly fill the tank, achieving the goal of rapid non-oxidation. However, during the opening and closing of the tank door, the nitrogen concentration inside the tank will temporarily decrease, which will lead to an increase in oxygen content and subsequently trigger oxidation reactions of the material components. If the recovery speed of the nitrogen concentration in the nitrogen tank is slow, the oxidation time of the material components will be prolonged. After multiple opening and closing cycles, this cumulative oxidation effect may cause the oxidation degree of the material components to exceed the controllable range, thereby affecting the performance of the product.
The detection and control of nitrogen concentration are complementary measures. Currently, the detection of nitrogen concentration usually employs the humidity detection method, while the more advanced method is to directly measure the nitrogen content. A decrease in oxygen content means an increase in nitrogen concentration. At the same time, by controlling the nitrogen flow rate, it is ensured that the appropriate amount of nitrogen is supplied when needed, thereby maintaining a stable nitrogen concentration inside the cabinet and avoiding unnecessary waste. This design aims to balance performance and nitrogen conservation.
It is worth noting that a high-quality nitrogen tank requires a good balance in the detection and control of nitrogen flow and concentration to fully ensure its performance and achieve effective nitrogen conservation. Moreover, the importance of anti-static function cannot be ignored, although some manufacturers may neglect this point due to cost considerations. However, the potential damage of static electricity to electronic products cannot be overlooked. An excellent nitrogen tank is scalable and can further evolve into a nitrogen-saving nitrogen tank, a nitrogen-free nitrogen tank, or a self-produced nitrogen tank, providing significant advantages for manufacturers in terms of long-term use and continuous performance improvement.
Key points for use
Meanwhile, during the usage process, the opening and closing times and frequencies of the nitrogen tank should be strictly controlled. Shortening the opening and closing time can effectively reduce the escape of nitrogen and maintain the nitrogen concentration inside the tank; while reducing the frequency of opening and closing can minimize the accumulation of oxidation on the materials and components. These operational measures are crucial for optimizing the storage effect. During the usage process, the nitrogen flow rate and concentration should be controlled, and the anti-static function should be emphasized to extend the service life of the nitrogen tank and enhance its efficiency.
