Nitrogen cabinet is to regulate nitrogen injection into the cabinet, and achieve dehumidification and oxidation prevention. Nitrogen cabinet is widely used in semiconductor factory, crystal oscillator factory and precision component factory. It is mainly used for moisture-proof and oxidation protection. For the factory, the moisture-proof and anti-oxidation preservation of these precision parts plays an important role in the yield of production to ensure the quality. In the normal use of nitrogen cabinet, how to evaluate its performance, users are generally reading the humidity of nitrogen cabinet distinguish. The working principle of nitrogen cabinet is to fill the cabinet with nitrogen, gradually replace the original air in the cabinet, and then achieve a relatively anaerobic and dry storage environment. If the humidity of the nitrogen cabinet is not up to standard, the moisture-proof and oxidation-proof effect of the storage items in the cabinet will decrease. Nitrogen cabinet humidity can’t meet the requirements, that is, the concentration of nitrogen in the cabinet can’t meet the requirements. For a limited sealed cabinet, its concentration can’t reach, only “air intake” and “air outlet” two reasons. “Air outlet” represents the sealing of the cabinet, partial filled-in nitrogen leak out . When the leakage is too large, the nitrogen concentration in the cabinet will be lower, and the humidity will be low, and it will not be able to protect against moisture and oxidation. The “intake air” represents the insufficient amount of nitrogen in the nitrogen cabinet In the process of using the nitrogen cabinet, due to the frequent opening of the cabinet door, the amount of nitrogen escaping from the switch door is larger than the amount of nitrogen filled into the cabinet, and the expected nitrogen concentration can’t be reached. The solution is divided into two parts, one is the sealing of the cabinet, the other is the increase of air intake. Manufacturers should avoid sealing problems, and intake valve failure in the N2 cabinet. Learn more, pls visit our website: https://www.dry-cabinet.cn/prolists2.html

The moisture-proof dry cabinet is to use all kinds of dehumidification technology to effectively reduce the humidity in the cabinet, so as to achieve the purpose of moisture-proof, mildew-proof, anti-oxidation, anti-rust, anti-micro moisture absorption and so on. What should you pay attention to when you go to buy a moisture-proof dry cabinet? 1. dehumidification materials are now on the market moisture-proof dry cabinet are basically using physical moisture absorption, such as moisture absorption card, plastic drying box and so on. These materials are basically consumables, need to be replaced after a period of time; bring great inconvenience to users. The EJER moisture-proof dry cabinet adopts polymer material to absorb moisture, and the dehumidification method of “shape memory alloy” system is used. The humidity setting range are <3%, <5%,1%-10%, 10-20%,20-60% RH, dehumidification at ambient temperature. 2. dehumidifier cover The selection of dehumidifier cover is also a problem that must be paid attention to when purchasing moisture-proof dry cabinet. General manufacturers will choose ABS materials, not resistant to high temperature, easy to melt. At present, there are many examples on the network because of the instability of domestic voltage, resulting in the melting of the main engine of the moisture-proof dry cabinet and the damage to the collection. EJER moisture-proof cabinet dehumidifier cover design: polymer physical structure, shell using PPS fire-proof material, power failure within 24 hours, automatically attached to chemical moisture absorption function, save power. 3. the stability of humidity There is no doubt that the better the stability, the better the quality of the product. Usually the requirement for low humidity is higher. 4. the dehumidification effect The more uniform the humidity of the moisture-proof cabinet, the better the dehumidification effect for the stored items, which means the safest and most reliable. Therefore, this has a high requirement for the internal air circulation system of the moisture-proof cabinet. EJER moisture-proof cabinet uses polymer physical core to control the advantages of humidity: strong dehumidification, no consumables, silent operation, dehumidification faster and more stable. 5.ESD Anti-static The EJER moisture-proof cabinet avoids the traditional moisture-proof box passive anti-static, adopts the ESD active anti-static, neutralizes eliminates the product static electricity, fundamentally eliminates the static electricity, conforms to the ESD standard 6. Temperature and Humidity Remote Control Data logging system by USB connection with computer for data reading and printing; Visit our website https://www.dry-cabinet.cn for more details.

The box is made of high-quality cold-rolled steel plate, sprayed on the surface, and the inner liner is made of high quality stainless steel. Between the inner casing and the outer casing is filled with rock wool for insulation . The temperature control system uses a microcomputer chip processor. With PID adjustment characteristics, time setting, temperature difference correction, over temperature alarm and other functions, high temperature control accuracy and strong function. The time setting range is: 0-9999 minutes. The blast circulation system sends heat to the working chamber through the air duct and forces the exchange of hot and cold air in the working chamber, thereby increasing the temperature uniformity of the temperature field in the working chamber. The printer and RS-485/232 interface can be added before ordering according to user's requirements. (option)

It is believed that in the future, China’s temperature test chamber manufacturers will become more and more diversified, the technical level of the industry will be higher and higher, and the quality of products will rise steadily. With the further standardized management of the industry and the implementation of preferential policies in some related industries, China’s temperature test chamber industry will have more and more space for development. Today we will introduce the use of temperature test chamber: At present, many semiconductor manufacturers do LED purchase temperature test chamber or thermal shock test chamber, the development of enterprise products need to encounter high low temperature will have a bad impact on the product, through the temperature and humidity test chamber? to do a test to see the product encountered high temperature, low temperature… Special is LED semiconductor industry, often do LED enterprises to control the temperature of products in a certain range.

Each product has its service life, the service life depends on its own quality, ambient condition, as well as daily maintenance, then we should know how to do usual maintenance correctly, in order to extend its service life. 1. the drying oven consumes a large amount of current, the power cord, knife switch, fuse, plug, socket and so on must have sufficient capacity. For safety, the exterior case should be connected to the ground wire. 2. the specimen put into the oven should not be too much, too crowded. If the dry items are wet, the exhaust hole should be opened. When heated, the blower can be started so that the steam can accelerate the discharge from the oven. But do not let the blower run continuously for a long time, pay attention to proper rest. 3. do not place items onto the heating panel at the bottom of inside oven, to avoid baking or burning. 4. when dry and hot sterilization of glassware, the temperature in the oven must be reduced before open the door so as not to burst the glass suddenly. 5. it is strictly forbidden to put flammable, explosive and volatile items into the box to avoid accidents. 6. need to observe the items in the constant temperature room, open the outer door and observe through the inner glass door. the door open frequency should not be too many, which affects the constant temperature. 7. starting or using for a period of time, the error between the measured temperature and the actual temperature in the studio must be checked, that is, the precision of temperature control. 8. drying oven housing must be well and effectively grounded to ensure safety. 9. when the drying oven studio temperature is close to the set temperature, the heating indicator lights suddenly turn dark, repeated many times, is a normal phenomenon. In general, about 15 minutes after the temperature reaches the control temperature, the working room temperature enters the constant temperature state. Correct use, daily maintenance, is the root of long-term use. EJER will strive to provide customers with one-stop service and a variety of solutions, for customers to solve the best.
