The role of air permeability of dust screen

1. Balance pressure

All electrical equipment housings that work outdoors are subject to temperature fluctuations as well as wind, rain and sunlight radiation. Once the dust enters the closed casing, if it is not removed in time. It will have a corrosive effect on sensitive electronic equipment. The dust screen with good air permeability helps to balance the pressure inside and outside the enclosure, prevents air and moisture from entering the inside of the enclosure through the sealing strip, and effectively protects the integrity of the sealing strip. Breathable products also speed up the dissipation of water vapor. This reduces the accumulation of moisture inside the enclosure and quickly eliminates condensation on the surface of devices such as displays.

2. The battery is breathable

In order to prevent the accumulation of explosive harmful gases inside the battery, the dust screen with good air permeability can avoid gas accumulation by adjusting the pressure. With good air permeability, the dust screen plays the same role as a mechanical safety valve in this case. For many types of rechargeable batteries, such as file-ion batteries, the heat generated during the discharge and charging process of the battery will increase the pressure in the battery box.

3. Sound quality guarantee

Devices such as mobile phones, computers, two-way radios and mobile defibrillators must be able to tolerate rougher usage and use environments. The dust screen with good breathability can effectively protect the components from various weather factors, and at the same time form a strong protective barrier for sounding equipment such as microphones, speakers and sirens, while effectively ensuring the quality of sound transmission.

4. Sensor protection

With the development of electronic technology. The range of applications for sensors is becoming wider and wider, and the application environments are becoming more and more diverse. Whether it is a harmful gas detector or a pH sensor, the size of various electronic sensors becomes smaller. The performance must meet more demanding requirements. In many cases. Harsh operating environments can quickly degrade sensor performance, resulting in reduced accuracy and lifetime. The dust screen with good air permeability can effectively prevent the penetration of most dusts and always maintain a high level of air permeability.
