Fundamentals of static electricity_knowledge_Aiyong Instruments (Suzhou) Co., Ltd.

Static hand rings are used to eliminate static electricity from the human body. It is commonly used for processes that are done manually at the workbench. As shown in the figure below, it constitutes a structure that allows the wrist to be grounded. By grounding the plate clip, the static electricity accumulated in the human body can be released to the ground and elimination can be realized.

Features

* The static electricity accumulated in the human body will immediately enter the earth through grounding, and the human body can be kept always without static electricity.

Cautions

* If you forget to ground the clip, it will lose its effect.

* It will deteriorate due to wear and tear and dirt after a long period of use.

Comparison of high-frequency ionization fans with conventional technology

The high-frequency ionization fan with extremely stable ion balance and high level of static elimination 70KHz per second discharge frequency waveforms more; ion balance, voltage changes over time with less amplitude; DC power supply, performance is more stable; high-frequency technology, high-voltage output generally only needs to be more than 2,000V can be, more security, energy saving, electromagnetic interference is small.

* Advantages of high-frequency technology

* Disadvantages of conventional technology

* Comparison of performance technologies

Temperature management (countermeasures against static electricity)

Features

* Can create an environment where static electricity is not easily accumulated.

Cautions

* Condensation and rust may occur, which may adversely affect objects and equipment.

* If the same conditions are applied to a large area, it is difficult to realize due to high cost.

Humidification cases (countermeasures against static electricity)

Humidity management usually involves the use of humidifiers. The diagram shows how static electricity is naturally discharged when humidity is high.

* Humidity management through humidifiers

Static Countermeasure Products - Antistatic Fluid

Sprays contain ingredients known as surfactants. Surfactants have the effect of making moisture more affinity with the object. After spraying the antistatic liquid, the object absorbs moisture from the surrounding air under the action of the surfactant and forms an easily conductive state on the surface. This creates a state that is less likely to generate static electricity.

* Static countermeasure supplies -- anti-static liquid

Conductor grounding (countermeasures against static electricity)

Grounding Grounding is a common countermeasure to static electricity found in everyday life. An example is the static electricity elimination panel at a self-service gas station. The board is directly grounded, and when it is touched by hand, the static electricity carried by the human body is directed to the earth through the ground. This effectively prevents accidents in which gasoline is ignited by discharging sparks. The same principle is applied to the production equipment. By simply grounding the equipment, static electricity can be eliminated.

Features

* The static electricity accumulated in the human body will immediately enter the earth through grounding, and the human body can be kept always without static electricity.

Cautions

* If you forget to ground the clip, it will lose its effect.

* It will deteriorate due to wear and tear and dirt after a long period of use.

Principle of Electrostatic Dust Adsorption

Charged substances approaching each other are subjected to the [Coulomb force].

* The more charged they are and the closer they are

* The stronger the attraction between each other

Corona discharge and ion generation

A high voltage is applied, which causes a corona discharge in which the air near the discharge needle is ionized and charged ions are produced.
