At present, in order to ensure the ex factory quality of products, domestic electronics must strictly control the temperature and humidity in the production plant, especially the humidity. If the plant is too dry, it is very easy to generate static electricity in the plant, causing damage to cmos integrated circuits (Note: the test shows that when the relative humidity is 20% RH, the static voltage in the plant is 10000V, and when the relative humidity is 10%, the voltage in the plant is very easy to generate 20000V).
In addition, too dry air will also cause dust flying in the air, induce respiratory diseases, affect the physical and mental health of workers, and reduce work efficiency! Generally speaking, the temperature of the electronic workshop is controlled at about 22 ℃ and the relative humidity is controlled at 40~60% RH. In this environment, people feel comfortable and static electricity disappears!
Note: If the frequency of fresh air ventilation in the electronics workshop is higher in winter, the oxygen content in the workshop will be higher, but the humidification amount required will also be higher
Selection of humidifiers for different types of electronic plants
1、 For electronic plants with central air conditioning units and humidification sections:
1. If the user wants the air supply temperature of the air conditioner to be higher and the adjustment accuracy to be higher:
l) If the user has no steam source or it is inconvenient and uneconomical to use steam, it is recommended to use a special ultrasonic humidifier for central air conditioning!
2) If the user has a steam source and is convenient to use, it is recommended to use a dry steam humidifier!
2、 For users with central air conditioning units, without humidification section, but with air supply ducts, who want humidification in the air duct:
- Users are recommended to adopt:
l) Electric humidifier mode
2) ZS series ultrasonic industrial humidifier!
3、 For users who do not have central air conditioning units and only install humidification equipment in the electronic plant
1. If the heat load in the user's workshop is large and the cold humidification method is desired:
l) If users have pure water, namely deionized water, it is recommended to use CS series ultrasonic pure water humidification method
2) If the user has no pure water, it is recommended to use ZS series ultrasonic industrial humidification method
2. If the heat load in the user's workshop is small and the user wants to use the thermal humidifying method, it is recommended to use the electric heating or electrode humidifying method!
