The two main factors in the air environment are humidity and temperature, which have profound significance and significant impact on people's lives, work, and industrial production. In the coating industry, it is necessary to strictly control the temperature and humidity in the workshop environment, and spray humidifier equipment, as a simple temperature and humidity control equipment, is widely used in this industry. For the painting workshop, strict control of temperature and humidity is required for the spray booth due to process requirements. The built-in temperature and humidity sensor in the humidifier can effectively monitor the temperature and humidity inside the coating line of the painting workshop, thereby ensuring production quality and improving product production efficiency.
In the spray painting workshop, such as solid wood furniture, the environmental factors that have a significant impact on the spray painting effect during the spray painting process are temperature, humidity, and air cleanliness. The temperature is generally controlled at 25 ± 3 ℃, and the humidity is generally controlled at 65 ± 15%. Both high and low temperatures and humidity are not good. If the temperature is too high, the gloss of the paint surface will be poor, and it will appear uneven and rough, resulting in orange peel phenomenon, and the paint film color will be lighter and whiter. As a simple humidification equipment, dry spray humidifier has no complex mechanical mechanism, and the humidification effect is direct and fast.
First of all, let's understand the principle of the spray. In short, due to the flow of air, the air with high humidity will move to the space with low humidity, and eventually the humidity in all locations will increase, thus reducing the number of air particles. When in use, the dry mist humidification system sprays water mist with an average particle size of 8 μ m. The dense and fine water mist easily captures fine dust in the air. The captured fine dust will naturally fall and settle due to its increased mass, while the uncaptured fine dust will absorb moisture from the air and naturally settle due to its increased mass.
With the increase of air humidity, the electrostatic voltage between air and dust will also decrease. When the relative humidity of the air inside the wire reaches 60%, the electrostatic voltage can basically drop to a lower point. At this time, the large floating dust accumulated by electrostatic effects in the air will disintegrate to a greater extent, forming tiny floating dust that will not produce paint particles.
Temperature and humidity sensors refer to equipment or devices that can convert temperature and humidity into electrical signals that are easily measured and processed. In actual production, it is of great significance to grasp and control temperature and humidity to improve production. Therefore, temperature and humidity sensors that integrate temperature and humidity have emerged on the market, generally measuring temperature and relative humidity.
In common humidifier systems, there are built-in humidity sensors and start-up control valves. The humidity sensors monitor the humidity inside the line and provide feedback to the controller
