Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for applying powder or granular materials under various gas atmosphere conditions.
And under various pressure and temperature conditions, plasma ions are irradiated to generate a physical or chemical reaction on the surface, activating the surface and imparting lipophilicity, hydrophilicity, or philophilicity. Alternatively, it relates to an activation device that improves dispersibility.

1 to 3 explain the principle of an embodiment of the present invention.

In FIG. 1, a conductive counter electrode 2 and an excitation electrode 3 are provided above and below with a dielectric 1 in between.

The counter electrode 2 is a flat plate in FIG.

The excitation electrode 3, which also serves as a heater, has the shape of a single winding wire, and a power source 6 for the heater is connected to the ends 4 and 5 of the excitation electrode 3.
The output of is applied.

On the other hand, an AC high voltage is applied to the counter electrode 2 and the excitation electrode 3 from a power source 7. This brings about the extremely important feature that the excitation electrode 3 generates a much larger amount of plasma ions than when the excitation electrode 3 is not heated by the heater power source 6. At the same time, the amount of ozone generated is much higher than when no heating is performed.

It is also possible to heat the excitation electrode 3 with the heater power source 6 before applying power from the power source 7, thereby drying the surface of the electrode more completely.

The upper diagram of FIG. 2 shows a structure in which the counter electrode 2 of FIG. 1 is buried inside a dielectric material.

The lower diagram in FIG. 2 shows a structure in which excitation electrodes 3 are provided on both sides of one dielectric 10.

FIG. 3 shows a structure in which a potential in an arbitrary direction is maintained on the electrode 8 by an electric current 9 (equivalent to a DC power source) in order to extract only plasma ions with a specific polarity from the excitation electrode 3. . For example, when a negative potential is applied to the electrode 8 from the power source 9, the electrode 8 and power source 9 shown in FIG. 3, which can cause the excitation electrode 3 to emit only positive polar ions, can be applied to the device shown in FIG. It is obvious that additional installations can be easily made.
