Humidity in the spray coating industry requirements

The production plants in the spraying industry are required to maintain a stable environment within the production environment, especially for the temperature, humidity, air cleanliness, airflow organization, pressure balance and other air-conditioning parameters in the climate conditions throughout the year. The strict requirements. Different from other constant temperature and humidity environment system requirements, due to high humidity environment on its quality, its accuracy on the humidity of the strict requirements for air-conditioning system configuration.

In general, the temperature and humidity conditions of the spray coating industry are: T = 24 ± 2 ° C, RH = 45 ± 5%; for this temperature and humidity requirements, traditionally used frozen dehumidification + post-heating (reheat) , And achieved some results. But this way there is a fatal problem, the hot and cold offset and a huge waste of energy consumption, especially because of the semiconductor industry Dah Sing wind, large exhaust system, the production environment for the large space clean environment and the current concentration of many plants mainly concentrated In southern China and East China's special circumstances, making this problem is very prominent.

Therefore, in the latest air-conditioning system of many spray booths, the use of fresh air through the new air unit (cooling dehumidification) and the rotor dehumidifier combined treatment of humidity, temperature and then through the rear air conditioning unit treatment combination to achieve the indoor air temperature and humidity requirements, And achieved significant gains.

Coating workshop dehumidifier is the supply of a different indoor and outdoor temperature on the indoor heating, cooling and dehumidification to meet the indoor temperature and humidity requirements of the temperature and humidity control methods and equipment, can improve the dehumidification thermostat system function , Extended dehumidification thermostat system limitations.

1. Coating workshop dehumidifier organically linked to the dehumidification and dehumidification dehumidification dehumidification two methods, advanced design is advanced, economic operation of the four seasons of intelligent air handling equipment. One is the use of refrigeration refrigeration dehumidifier refrigeration, the air temperature dropped to below the dew point, the discharge of condensate, so that the air humidity.

2. Because the moisture desorption regeneration can be applied to the compressor condensing waste heat to take over, but also make the rotor fever, and thus dehumidification through the wheel after the air temperature will rise, so that the air into the painting relative humidity is relatively low.

3. In the paint shop production process mainly in the main sandblasted paint, and in these processes useful in dealing with the appearance of metal oxidation and oxidation problems, the most economical way is to control the coating with special industrial dehumidifier coating air relative humidity , And then extended the oxidation process of the metal surface (steel surface) within the confined space.

4. Dehumidification coating shop to reduce the dew point of the surface temperature of steel to deal with large-scale appearance of structural steel oxidation, but also to avoid the staff of the new rust corrosion of the steel plate to accelerate the evaporation of solvents to ensure real-time boring coating.
