Dynamic triboelectric characteristics and protective effectiveness of ESD gloves in human motion
Publish Time: 2024-12-03
ESD gloves play a key protective role in many static-sensitive working environments. However, when the human body is in motion, the dynamic triboelectric characteristics and protective effectiveness of gloves face special challenges and complex changes.
When the human body moves, frequent friction occurs between the hands and surrounding objects and the internal fibers of the gloves themselves. The dynamic triboelectric characteristics of ESD gloves are different from those in static situations. Under rapid limb movements, factors such as the frequency, force and contact area of friction are constantly changing, resulting in a more complex process of charge generation and accumulation. For example, in an electronic assembly workshop, workers' hands need to constantly grab and place parts, and their arms frequently flex and extend. In this dynamic process, the friction between gloves and parts and tools may instantly generate a large amount of charge.
To study its dynamic triboelectric characteristics, it is necessary to use advanced electrostatic detection equipment to monitor the potential changes, charge density and other parameters on the surface of the gloves during movement in real time. By simulating different human motion patterns, such as rotation, flexion and extension, and fisting, the laws of triboelectric charging under various motion postures are analyzed.
The effectiveness of protection is the key indicator to measure whether ESD gloves can really play a protective role when the human body is in motion. Even if the gloves have a certain static dissipation ability when static, if the generated charge cannot be conducted away in time during dynamic movement, it may cause an electrostatic discharge accident. For example, in a flammable and explosive chemical production environment, electrostatic discharge may cause a fire or explosion. The effectiveness of protection depends not only on the conductive fiber performance and weaving structure of the gloves themselves, but also on factors such as the fit between the gloves and the skin and the change of the air layer during human movement.
In order to improve the effectiveness of the protection of ESD gloves in human motion, comprehensive considerations are needed in the design and manufacture of gloves. Select conductive fibers with better conductivity and high stability, optimize the knitting structure to enhance the charge conduction path, and adopt an ergonomic design to ensure that the gloves always fit the hands tightly during exercise and reduce the accumulation of static electricity caused by changes in the air gap. In addition, users need to be trained on the correct wearing and use of gloves so that they understand how to maximize the protective function of gloves during exercise, thereby ensuring the safety and stability of the working environment.
