It is known from the law of conservation of charge that charge can neither be created nor destroyed. Charges can only be transferred from one object to another, or from one part of the object to another. According to the principle of the law of conservation of charge, the prevention and control of statical obstacles can only be groomed. It should be started from the following aspects:
1. Accelerate the leakage and dissipation of static electricity.
When static electricity is generated on the surface of the object, the electrostatic charge is leaked and dissipated by the characteristics of the material itself, so that the static electricity can no longer accumulate on the surface of the body, reducing the electrostatic charge per unit area, thereby preventing the electrostatic discharge from occurring.
Therefore, electrostatic conductors or static dissipative materials are implanted on the surface or object of the object to construct a channel for electrostatic leakage and dissipation. By the action of such materials, the static electricity on the object is released in time, so that the static electricity can no longer be surfaced. Accumulate and reduce the static electricity per unit area, so that the static electricity is controlled within the safe range to prevent the concentrated discharge of static electricity.
The use of conductive yarns to create electrostatic leakage and dissipation channels in antistatic textiles is a typical example of this principle.
2. Electrostatic discharge and grounding
The object is electrically connected to the earth through an electrically conductive, antistatic material or an antistatic product, so that the static electricity is close to the potential of the earth, and the electrostatic subconductor is provided with a leaking passage.
Electrostatic grounding is the most direct and effective measure of electrostatic discharge.
3. Static neutralization.
Electrostatic neutralization is essentially electrical neutralization. That is, the combination of positive and negative charges, the balance of the amount of charge is reached, and the externality is not sensible.
Two objects with equal heterogeneous charges, one with electrons and a positive charge, the other with electrons and a negative charge, one for which electrons are lost and the other for electrons; when electricity is neutralized, negatively charged objects The excess electrons are transmitted to objects that are positively charged due to lack of electrons, so that the process of restoring the atoms of both objects to electrical neutrality is electrostatic neutralization. Therefore, the two objects do not display electrical properties.
4. Electrostatic shielding
The electrostatic shielding is to avoid the influence of the external electrostatic field on the charged or non-charged body, or to avoid the influence of the electrostatic field of the charged body on the outside world, the charged or uncharged body is placed in a grounded closed or nearly closed metal casing or Measures within the metal grid.
5. Environmental humidification
Using a near-saturated, high-temperature hot air slightly above the surface temperature of the medium to reach the dew point on the surface of the medium to condense, using the low resistivity of the condensed water film to conduct the charge away, while the water film evaporates quickly, taking away the residual charge.
