Anti-static work clothes
Anti-static work clothes are made of anti-static fabrics. Everyone should be aware of this. The fabrics are divided into conductive silk and TC cotton. The weaving method of conductive silk is divided into vertical strips and nets. Different fabrics are produced. The friction voltage of the electrostatic clothing is completely different. The more conductive filaments, the better the electrical conductivity of the electrostatic clothing. It can automatically corona discharge or leak discharge, which can eliminate the charge of clothing and the human body. The static voltage generated will be lower. The structure of it!
Anti-static fabric is also called anti-static fabric, or anti-static fabric for short.
【Principle of action】
The electricity elimination is based on two mechanisms: the discharge and neutralization of electric charges.
When grounded, the static electricity on the fabric is neutralized by the corona discharge of the conductive fiber, and can also be discharged to the ground through the conductive fiber;
When not grounded, the weak corona discharge of the conductive fiber is used to dissipate electricity.
【Corona discharge】
The local self-sustained discharge of a gas medium in an uneven electric field is the most common form of gas discharge.
It is near the ** electrode with a large radius of curvature. Because the local electric field strength exceeds the gas ionization field strength, the gas is ionized and excited, and corona discharge occurs. When a corona occurs, bright light can be seen around the electrode, accompanied by a hissing sound.
Material: Using polyester as the main body.
Special polyester filaments and high-performance, long-lasting conductive fibers are woven by a special process in warp-direction weaving or warp and weft-direction weaving conductive fibers.
【Anti-static silk】
Performance: Garments made with this fabric through a special sewing process have excellent anti-static and dust-proof performance, anti-static efficiency and long-lasting. It has the characteristics of softness, thinness and clear texture. Mainly used to make dust-proof clothing and anti-static clothing.
Conductive fiber: stripe type, spacing 10mm, 5mm, etc.
Grid type 5mm, 2.5mm and so on.
Parameters: Surface resistance 10^6Ω-10^9Ω.
At present, the electronic industry not only requires the resistance value of anti-static clothing to meet the standards, but also the friction voltage requirements are constantly increasing. For example, electronics, chemicals, aerospace, and precision instruments have high requirements for friction voltage. A few days ago, a customer in Shenzhen called: The friction voltage of the anti-static clothing in their factory cannot pass the test. After understanding, the customer requires the static voltage to be lower than 100 volts. At present, the anti-static clothing worn in their production workshop is all straight gowns, and the friction voltage cannot meet the product withstand voltage requirements. The friction voltage must be controlled within the withstand voltage range of the product. If the technical department does not know the withstand voltage of the product, the purchaser does not know what kind of anti-static clothing to buy for the workers in the production workshop, which will cause this phenomenon.
There are different quality of anti-static clothing in the market, and even some anti-static fabrics have almost no anti-static effect after several washings. Therefore, it is recommended that customers require suppliers to provide effective reports or provide samples for testing during the procurement process. If the quality is unqualified, the protective effect will not be achieved, but the product will be burned out, or unexpected unexpected explosions occur, and the loss caused is immeasurable.
