Abstract

PROBLEM TO BE SOLVED: To provide a dielectric roll for corona discharge treatment which can efficiently enhance the affinity of surface of a film such as a plastic film and paper. SOLUTION: A first dielectric roll is a dielectric roll for a corona discharge treatment apparatus made by providing an insulation film layer 2 over the circumference of a roll-type center material 1 and covering the circumference of the layer 2 with a ceramic film layer 3. A second dielectric roll is made by applying a metal to the roll-type center material of the first dielectric roll. A third dielectric roll is made by processing the roll-type center material of the first dielectric roll with a fiber glass, a carbon fiber or a composite material therefrom. A fourth dielectric roll is made by forming the insulation film layer of either one of the first through to the third dielectric rolls with either of insulation resins such as a flexible epoxy resin, a polyimide resin, a polyamide resin, a fluorocarbon resin and a PEEK resin. A fifth dielectric roll is made by forming the insulation film layer of either one of the first through to the third dielectric rolls with a mixture of a ceramic material and a resin.

As shown in FIG. 3, the above-mentioned dielectric roll B uses a metal roll D provided with a dielectric film E on the surface thereof. By coating the metal roll D with the dielectric film E, it is possible to prevent the corona from being in an arc state. The dielectric for the film E is required to be able to withstand high voltage, to be as thin as possible, to be inexpensive, not to be affected by ozone, to have a high dielectric constant, and to have a small electric loss. Properties are desired. Further, if the voltage applied to the dielectric roll B is increased to increase the surface treatment capacity, the roll B generates heat, so that heat resistance enough to withstand the heat is required. Conventionally, pylon rubber, EPT rubber, silicon rubber, ceramics, and the like have been used as dielectrics requiring these various conditions, and in particular, ceramics have been used in recent years.

SUMMARY OF THE INVENTION Pylon rubber, EPT
Rubber, such as rubber and silicone rubber, is apt to deteriorate in insulation, easily wear due to heat of corona discharge, and is hard to withstand long-term use. In addition, rubber has a problem that air bubbles are easily generated, the air bubbles are melted by the heat of corona discharge, holes are formed in holes of air bubbles, and insulation is deteriorated.

A dielectric roll using ceramics for the film E is excellent in wear resistance and heat resistance, but has the following problems. 1. Since the thermal expansion coefficient and the shrinkage rate of the metal roll and the ceramic film are different, the metal roll and the ceramic film are easily separated from each other after long-term use. Further, since the ceramic film has poor elasticity and is brittle, it is easily cracked or broken. 2. Since the ceramic film is formed by plasma spraying, pinholes are formed in the ceramic film, and there is a problem in insulation. By the way, ceramic film thickness is 0.1m
In the case of a dielectric roll having a thickness of 3,000 m, insulation properties that can withstand 1 second application at 3000 V and 1 A are required, and when the thickness of the ceramic film is 0.3 mm, insulation properties that can withstand 1 second application at 5000 V and 1 A are required. Is done. 3. In recent years, the thickness of the ceramic film has been increased to 0.5 mm to 3 mm in order to enhance the insulating property. However, such a thick film increases the cost of the dielectric roll because the ceramic is expensive.

The dielectric roll for corona discharge treatment of the present invention has the following effects because the insulating coating layer is provided between the roll-shaped core material and the ceramic coating layer. (1) Since the insulating film layer is flexible, the insulating film layer can follow expansion and contraction due to thermal expansion of the core material and the ceramic film layer, and the expansion and contraction is absorbed by the insulating film layer, and the ceramic film layer is cracked. It is less likely to enter or break the ceramic coating layer. Also, the ceramic coating layer is less likely to peel off from the insulating coating layer. (2) The insulating film layer enhances the insulating property, and pinholes and the like hardly occur in the ceramic film layer. Therefore, the thickness is significantly thinner than the ceramic film layer of the conventional dielectric roll for corona discharge treatment. Manufacturing cost is greatly reduced. (3) High dielectric constant and low electrical loss. (4) Since the insulating film layer also has a function as an anchor material (adhesive), the ceramic film layer is securely adhered to the core material via the insulating film layer and is hardly peeled off. (5) When the insulating film layer is a mixed material of ceramics and resin, it has both characteristics of ceramics and resin.
