Modern temperature and humidity sensor technology can improve the production quality in the spray sh

The two main factors in the air environment: humidity and temperature, they have great significance and influence on people's life, work and industrial production. In the painting industry, it is necessary to strictly control the temperature and humidity in the workshop environment, and the spray humidifier equipment as a simple temperature and humidity control equipment is widely used in this industry. For the painting workshop, such as the spray booth for the process needs, the temperature and humidity need to be strictly controlled. The temperature and humidity sensor built into the humidifier can effectively monitor the temperature and humidity inside the coating line in the painting workshop, so as to ensure the production quality and improve the production efficiency of the product.

In the spray workshop, in the process of painting wood furniture in the spray room, the environmental factors that have a greater impact on the spray painting effect are temperature, humidity and air cleanliness. The temperature is generally controlled at 25±3℃, the humidity is generally controlled at 65±15%, and the temperature and humidity are too high and too low. If the temperature is too high, the gloss of the paint will be very poor, and it is not smooth, more rough, resulting in orange peel phenomenon, and the color of the paint film is light and white. As a simple humidifier, the dry spray humidifier has no complex mechanical mechanism, and the humidification effect is direct and fast.

First of all, understand the principle of the sprayer, 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 of all locations will increase, thereby reducing the number of air particles. When in use, the dry fog humidification system ejects water mist with an average particle size of 8μm, dense and fine water mist is easy to capture the dust in the air, the captured dust will naturally fall and settle due to the increase in mass, and the uncaptured dust will also absorb the water in the air, and the mass will increase and naturally settle.

With the increase of air humidity, the electrostatic voltage between the air and dust will also decrease. When the relative humidity of the air in the line reaches 60%, the electrostatic voltage can basically drop to the lowest point. At this time, the large floating dust gathered by the electrostatic effect in the air disintegrates to achieve the maximum effect, forming a small floating dust that will not produce paint particles.

The temperature and humidity sensor is a device or device that can convert the temperature and humidity into an electrical signal that can be easily measured and processed. In actual production, it is of great significance to grasp and control temperature and humidity for the improvement of production. Therefore, temperature and humidity sensors have emerged as the market temperature and humidity sensors, generally measure the amount of temperature and relative humidity.

In a common humidifier system, a humidity sensor and a startup control valve are built in. The humidity sensor monitors the humidity inside the wire and feeds back to the controller. The controller opens the valve according to the humidity inside the wire and finally starts the humidifier to humidify the chamber.

At present, most of the popular temperature and humidity sensors on the market are digital output, mining network introduced a digital temperature and humidity sensor from abroad - HTU21D, the built-in temperature sensor can be in the same package with the humidity sensor, can measure the relative humidity) temperature compensation, and provide a second independent temperature sensor output. The user replaces two sensors with one sensor. In addition, such temperature and humidity sensors have the advantages of low energy consumption and high precision. However, different temperature and humidity sensors vary greatly in principle and structure, and when selecting related products, temperature and humidity sensors can be reasonably selected according to the specific measurement purpose, measurement object and measurement environment.
