Anti-static clothing is an effective way to prevent static electricity
Workers who have worked in electronics factories must be familiar with anti-static clothing. Every day before going to work in the workshop, they will wear a full set of anti-static clothes, and then go to work after dust removal and disinfection.
Anti-static clothing is the widest and most numerous of all special protective clothing. The dust-free workshop has high requirements for anti-static and dust-proof. Employees entering the workshop must wear anti-static clothing to ensure product quality and keep the workshop environment clean. What types of anti-static clothing are there? Which industries need to wear? What material is it made of? How to wear it correctly? With these questions, we will introduce you to the "mystery" of anti-static clothing.
Fabric is the "soul" of anti-static clothing
"With the rapid development of high technology, people no longer know nothing about static electricity, but try their best to effectively prevent static electricity and minimize the harm of static electricity. Anti-static clothing is an effective way to prevent static electricity." Anti-static clothing It is suitable for static sensitive places or explosive places such as fire. It is widely used in electronics, optical instruments, medicine, microbiological engineering, precision instruments, petrochemical, military and other industries. Anti-static clothing is usually used with anti-static shoes, anti-static hats, anti-static gloves, anti-static wrist straps and masks. People who come into contact with electronic precision instruments and flammable and explosive materials need to wear protection.
The reason why antistatic clothing has good antistatic and dustproof performance is closely related to its fabric. It can be said that antistatic fabrics are the "soul" of antistatic clothing. The special polyester filament for antistatic clothing fabric is woven by conductive fibers in the warp or weft direction, which has high efficiency and long-lasting antistatic and dustproof performance. In the process of making garments, special sewing machines are used to effectively reduce the production of particles. The dust-free hook and loop tape avoids the pollution of lint to the environment. Different styles are provided according to the requirements of the purification level, sewn with conductive fibers to maintain electrical continuity in all parts of the garment; the sleeves and trouser legs adopt a unique double-layer structure, and the inner layer uses conductive or antistatic threads to meet the requirements of a high-level dust-free environment.
Anti-static clothing is usually divided into three types: gown clothing, split clothing and coveralls. The anti-static coverall is better than the first two because it has a larger body coverage and better air tightness. It is suitable for environments with high requirements for anti-static and dust-free. Because static electricity is very harmful to electronic products, anti-static clothing plays a very important role in the production of electronic products. Once static electricity is out of control, it may cause a series of losses, especially in the semiconductor and electronic product industries. Human body static electricity is the biggest threat, and even a bending action can generate enough static electricity to break through the chip, causing product damage and equipment failure. The harm of static electricity has a certain degree of concealment. In many cases, static electricity will harm the product, but it will not completely damage the product. Therefore, it is not certain whether there are problems during the factory inspection. Product quality problems occur during the user's use. This is also the reason for the unstable quality and short service life of some electronic products.
Anti-static clothing can only function better if worn properly.
Before entering the workplace, wear anti-static clothes, gloves, anti-static caps and masks in the changing room, and finally wear anti-static white shoes. After everything is ready, go into the air shower room to remove dust and disinfect before entering the workshop.
Some people may feel that wearing anti-static clothes every day is troublesome and airtight. It is more uncomfortable than wearing ordinary clothes, and I am not used to it. "It takes about a week or so to fully adapt. After proficiency, I put on anti-static clothing quickly and accurately in about 2 minutes. Some electronics companies are one-stop service providers that integrate PCB design, manufacturing and patch installation. Because Static electricity is very harmful to electronic products, so every employee who enters the workshop must wear anti-static clothes. Wear anti-static clothes to better play the role of work clothes."
"At present, we mainly produce carrier boards for mobile phone chips. A carrier board requires more than 40 processes such as cutting, drilling, copper plating, and gold plating. With the development of science and technology, many processes can be completed by automated equipment. We only need Write programs on the computer."
How to wear anti-static clothing correctly
Anti-static coat
Wear a gown first, pay attention to tightening the neckline, and the cuffs must be at the wrist position; wear gloves and tie the cuffs of the anti-static clothes into the gloves; trim your hair before wearing the anti-static cap, and try to cover all the hair in the cap; Wear a mask; wear anti-static shoes.
Split suit
Wear trousers, then coat. Be careful to fasten your neckline; wear gloves; trim your hair before wearing an anti-static cap, and try to cover all your hair in the cap; wear a mask; wear anti-static shoes.
Coverall
Grasp the opening of the waist zipper of the anti-static clothing, put on the lower limbs, then the upper limbs, then pull the zipper to the chest, put on the one-piece cap, and finally pull the zipper to the top and put on the neckline; wear gloves and put on the anti-static clothes Put your cuffs into your gloves; trim your hair before wearing an anti-static cap and try to cover all your hair in the cap; wear a mask; wear anti-static shoes or rubber shoes and shoe covers, and carefully check the entire set of anti-static equipment to determine whether there is Missing or damaged.
