As nitrogen is an inert gas, it is often used to protect objects to prevent certain objects from being oxidized by oxygen when exposed to air. For the oxidation of articles, the oxidation reaction is mainly caused by the contact of oxygen in the air with metal materials. The anti-oxidation method of the nitrogen cabinet is to create an oxygen-free environment in the cabinet to achieve the effect of anti-oxidation. Nitrogen cabinets are widely used in semiconductor factories, Jingyuan crystal oscillator factories and precision components factories, and they are mainly used for moisture and oxidation protection when these precision components are stored. For the factory, the moisture-proof and anti-oxidation preservation of these precision parts plays an important role in the production yield and product quality.
If the humidity of the nitrogen cabinet is not up to the standard, the moisture-proof and anti-oxidation effect of the items stored in the cabinet will decrease. The humidity of the nitrogen cabinet cannot meet the requirements, that is, the nitrogen concentration in the cabinet cannot meet the requirements. For a limited sealed cabinet, the concentration cannot be reached, and there are only two reasons for "intake" and "outflow".
"Out of air" represents the tightness of the cabinet, and the part that escapes after nitrogen is filled. When the escape volume of the nitrogen cabinet is too large, the nitrogen concentration in the cabinet will be relatively low, and the humidity will be high, and good protection against moisture and oxidation cannot be carried out.
"Intake" means that the amount of nitrogen filled in the nitrogen tank is insufficient. During the use of the nitrogen cabinet, due to the frequent opening of the cabinet door, the amount of nitrogen escaping from the opening and closing door is greater than the amount of nitrogen charged into the cabinet, and the expected nitrogen concentration cannot be achieved.
To sum up, the main criteria for selecting a nitrogen cabinet are the tightness of the cabinet and the intelligent adjustment of the nitrogen volume. Yee Hing Industrial Nitrogen Cabinet, door seal and rubber strip adopt built-in airtight installation method, no air leakage, good sealing performance, to ensure the stability of the humidity of the nitrogen cabinet, and adopts an automatic program-controlled induction system to automatically control according to the set humidity , When the humidity in the nitrogen cabinet reaches the set value, the system will automatically cut off the nitrogen supply. When it exceeds the set value, the system will intelligently turn on the nitrogen supply, which saves more than 50% of gas than manual nitrogen filling.
