Why do electronic factories wear anti-static clothes at work
The electronic factory must wear anti-static clothes and anti-static shoes when working, and some special posts, such as circuit board repair and installation of components, also need to wear anti-static bracelets or anti-static finger covers.
Wearing anti-static clothing and other protective articles is mainly used to avoid damage to electronic components caused by human body's own charge.
There are many places where you work in an electronics factory with positive and negative charges.
If you touch those with electricity, you may get an electric shock, which will have an impact on your personal safety.
The ordinary clothes we usually wear will generate static electricity due to mutual friction. Some devices used in electronic factories will be afraid of static electricity.
Therefore, in order to prevent human static electricity, we need to wear anti-static clothes and anti-static shoes.
Anti static clothing is made of man-made fiber and conductive fiber, which has excellent and lasting conductive properties.
Anti static clothing is a necessary measure for anti-static of personnel clothing.
The work clothes have a charge of < 0.6 micro library / piece and a charge area density of < 7 micro library / m2.
Anti static clothing is mainly made of stainless steel fiber, sub conductive fiber, anti-static synthetic fiber and polyester cotton blended or blended fabric.
It can automatically corona discharge or leakage discharge, and can eliminate clothing and human J static electricity. In addition to clothing, it can also be used to make anti-static hats, socks, shoes, etc.
We should pay attention to the following points when wearing and taking off anti-static clothes:
1. Relative humidity ≤ 30%, the charged capacity of pure cotton clothes is lower than that of chemical fiber clothes under relative conditions, and anti-static clothes made of sub conductor materials shall be worn in high-voltage charged working places;
2. It is forbidden to wear or take off anti-static clothes in flammable and explosive places;
3. It is forbidden to attach or wear any metal objects on the anti-static clothing; When wearing anti-static clothing, it must be matched with anti-static shoes specified in gb4385, as well as corresponding anti-static headgear and anti-static gloves.
Static electricity is harmful to any electronic product and has a great impact, so the top priority of the electronic processing industry is to effectively release static electricity.
The circuit is quite sensitive to high electrostatic voltage. When people or objects with static electricity touch these devices, static electricity will be released.
When the electrostatic high voltage impacts the circuit, the oxide film inside the circuit will be broken down and damaged, resulting in the on-the-spot damage or abnormal operation of electrical parts.
Of course, generally, devices that have been released by static electricity will not fail immediately, which is why most people do not pay attention to static electricity protection.
In addition, static electricity can also cause harm to people's body, so we should attach great importance to it. In a special working environment, we should pay attention to personal safety and not hurt ourselves.
Therefore, we must wear a complete set of anti-static protective articles and do a good job in safety protection.
