How to prevent static electricity

In our daily life, static electricity sometimes occurs. This is closely related to climate, clothing, and friction. Sometimes we don’t pay attention to static electricity and think it is a normal phenomenon. However, static electricity accumulated in the body for a long time will cause electric shock and pain when it suddenly touches metal. When it often happens at some stages, it can cause some psychological damage. So how to prevent static electricity?

In autumn and winter, the climate is very dry. When we are at home or go out, there will be an obvious phenomenon, that is, static electricity. Static electricity also has an impact on our lives. As for how to prevent static electricity, we will give you a detailed introduction based on some experience.

1 Wash your hands before going out, or wipe your hands against the wall to remove static electricity! Also, try not to wear floral clothes.

2 To avoid static electricity shock, you can use small metal devices (such as keys) or cotton rags to touch the door, door handles, faucets, chair backs, bed rails, etc. to eliminate static electricity before touching them with your hands.

3. Wear cotton underwear.

4 When you are ready to get off the car, hold the gear with your right hand, and touch the iron part below with your fingers. Then open the door and put your left hand on the iron part of the door, but don't let go of your left hand. Then let go of your right hand and get off the car. At this time, you will not be electrocuted if you hold the door with your right hand. . Next, close it with force.

5 To deal with static electricity, we can take both "prevention" and "release" methods. "Prevention": we should try to choose pure cotton products as the fabrics of clothes and home accessories, and try to avoid using chemical fiber carpets and furniture with plastic surface materials to prevent frictional electrification. Keep away from electrical appliances such as televisions and refrigerators as much as possible to prevent induction electrification. "Release" means to increase the humidity so that local static electricity can be easily released. When you turn off the TV and leave the computer, you should wash your hands and face immediately to release the static charge on the skin surface in the water. In winter, try to use highly moisturizing cosmetics. Commonly used humidifiers. Some people like to raise ornamental fish and daffodils indoors, which is also a good way to regulate indoor humidity.

6 I recommend you an economical and practical humidification method: place a basin of water under the heater, use an old towel (or a cloth that absorbs water well), put one end in the water and the other end on the heater, so that about three liters of water can be evaporated into the room in a day and night. If each heater does this, the whole room will feel moist and pleasant. You might as well give it a try.

7. Taking a bath and changing clothes frequently can effectively eliminate static electricity accumulated on the human body surface.

Work or industrial anti-static

1Electricity is an objective natural phenomenon, which is generated in many ways, such as contact, friction, rushing current, etc. The basic process of its generation can be summarized as: contact → charge → transfer → formation of double electric layer → charge separation.

2. The static electricity on the equipment or human body can reach tens of thousands of volts to hundreds of thousands of volts, and under normal operating conditions, it often reaches hundreds to thousands of volts. The human body can carry thousands or even tens of thousands of volts of static electricity due to its own movements and contact, separation, friction or induction with other objects. Static electricity is the result of the loss of balance between positive and negative charges in a local area. It is a kind of electrical energy that remains in the performance of objects and has the characteristics of high potential, low charge, small current and short action time.

3. The main measures for static electricity control are: static electricity leakage and dissipation, static electricity neutralization, static electricity shielding and grounding, and humidification.

4. Component breakdown damage caused by electrostatic discharge is the most common and serious electrostatic hazard in the electronics industry. It is divided into hard breakdown and soft breakdown. Hard breakdown is a one-time breakdown, burning or permanent failure of the component dielectric; soft breakdown causes the performance degradation of the device or the decline of parameter indicators.

5. Antistatic loading boxes, component boxes, turnover boxes, turnover pallets, etc. must be used for the transfer and storage of electrostatic sensitive components and printed circuit boards during the production process to prevent the harm caused by static electricity accumulation. Antistatic shielding bags, packaging bags, packaging boxes, baskets, etc. must be used for packaging of finished products to avoid static electricity damage during transportation.

6. During the production process of electronic products, components and finished products often come into contact, separate and rub with equipment and tools, which generates static electricity. Anti-static cushions, turnover carts, maintenance kits, tools, work chairs, etc. must be used, and proper grounding must be used to quickly discharge static electricity.

7 Frictional electrification and human static electricity are two major sources of harm in the electronics and microelectronics industries. However, the generation of static electricity is not the harm. The harm lies in the accumulation of static electricity and the resulting discharge of static electricity. A charged object forms an electrostatic field around it, which will produce mechanical effects, discharge effects and electrostatic induction effects, so it must be controlled.

8 Due to the mechanical effect of static electricity, floating dust particles in the air will be adsorbed onto components such as silicon wafers, seriously affecting the quality of electronic products. Therefore, anti-static measures must be taken for the clean room. The walls, ceilings and floors of the clean room should be made of anti-static and dust-free materials, and a series of anti-static protection measures should also be taken for operators, workpieces and equipment.

9. In order to understand the electrostatic charging situation in the production process, determine the impact of static electricity in the production process, and inspect the quality of electrostatic protection products and equipment, it is necessary to measure static electricity and related parameters.

10. Static electricity protection is a systematic project. Any omission or mistake in any link will lead to the failure of static electricity protection. It must be prevented at all times and by everyone.

I believe everyone has encountered the phenomenon of static electricity, especially in dry climates. Sometimes hair is easily electrified. Don’t we all hate static electricity in hair? It will make hair fly everywhere. So, you should learn more about how to prevent static electricity. These methods of preventing static electricity have been tested for a long time and the effects are very good.
