Static eliminator is being used. There are two typical methods of removing static electricity that have been conventionally used: (1) using an ion wind static eliminator and (2) using a self-discharge brush (static elimination brush).

ある。The ion wind static eliminator is a method of blowing air containing ions generated by corona discharge and blowing it on a charged body to neutralize or eliminate the charge, and a method of using a self-discharge brush is as follows. Bring a good conductor close to the charged object,
This is a method of self-discharging the electric charge of the charged body to remove the electric charge.

る。The static elimination brush used in the above-mentioned self-discharge brush method is made of a metal having a very low electric resistance, a conductive foil or fiber, a chemical fiber plated with metal, a fiber kneaded with metal or conductive carbon black, and the like. It is used. These foils and fibers are commonly referred to as electrodes in this field.

などの課題がある。The method using the ionic wind has an advantage that the charged body is not damaged because the device does not come into contact with the charged body. Since it generates ions, the corona discharge electrode wears quickly, dust generation due to electrode wear is inevitable, sparks occur, it cannot be used in the presence of flammable solvents, and the balance of the ionic wind is disrupted. In this case, there are problems that the electric charge may be further applied to the charged body, the apparatus cost is high, and the electrodes need to be regularly cleaned.

ある。The method using the self-discharge brush is as follows.
The structure of the device is simple and the cost is low, the material of foil or fiber to be the electrode, the thickness of foil, the diameter and number of fibers, and the metal support are arranged according to the charge amount of the charged object and the degree of its removal. There is an advantage that the distance between the fibers to be changed can be changed.

を与えるという問題がある。However, in the self-discharge brush, the electrode often contacts the charged body during its use, and the foil or fiber as the electrode is easily damaged by the contact. In the case of the plated fiber, the plating is peeled off. However, there is a problem that the charged body is damaged.

発する。Even if the above-mentioned foil or fiber is used with a narrow interval on the object to be charged, the charge on the object to be charged can be eliminated by self-discharging, but less than 10,000 V, especially 1,000 V or less. In the case of the charging voltage, it is necessary to bring the electrode into contact with the member to be charged, and in such a case, the electrode is frequently damaged.
