As shown in the figure, the thickness is about 0.05 mm and the width is 4 to 50 mm.
A polypropylene tape having a width of about 0.2 mm and a width 5 to 10 mm larger than that of the conductive tape 1 is used. A tape having an insulating coating 2 formed by thermocompression bonding the conductive tape 1 at the center in the width direction and sandwiching it from both sides is used. Has been.

複雑となるだけでなく、イオン化電極によりオゾンが発
生し人体に悪影響を与える問題がある。However, the use of an electrode in which the outer circumference of such a conductor is covered with an insulator requires an ionization electrode for giving a charge to particles in a gas, and in particular, a small electrostatic precipitator has a complicated structure. However, there is a problem that ozone is generated by the ionization electrode and adversely affects the human body.
本考案は、容易に製造できイオン化電極を必要としない
陽極材を提供することを目的とする。It is an object of the present invention to provide an anode material that can be easily manufactured and does not require an ionization electrode.

気集塵機用陽極材にある。The present invention has a conductive tape made of an aluminum foil tape, and a volume resistivity value of 10 10 to have a portion that surrounds the outer circumference of the conductive tape and extends outward from both widthwise edges of the conductive tape.
Anode material for an electrostatic precipitator consisting of a semi-conductive layer made of 10 17 Ω · cm ethylene-ethyl acrylate copolymer resin and a polypropylene insulating coating that surrounds the semi-conductive layer with both widthwise edges of the semi-conductive layer exposed. It is in.
この陽極材は、電気集塵機内に陰極材と平行に配置さ

体中の粒子に荷電を与えることが出来るので、イオン化
電極を不要に出来る。This anode material is arranged in parallel with the cathode material in the electrostatic precipitator, and is used by applying a voltage of 2 to 3 KV between both electrodes, but the semiconductive layer is provided by being exposed to the outside from the insulating coating. As a result, a slight leak current can be generated from this, and the particles in the gas can be charged, so that the ionization electrode can be omitted.
この半導電層の体積固有抵抗値が1010Ω・cm未満では、
漏れ電流が大きくなり過ぎて火花放電を生じ発火の原因
となるだけでなく、短期間で絶縁被覆の劣化を生ずるの
で好ましくなく、1017Ω・cmを超えると漏れ電流が無く
なり、気体中の粒子に荷電出来なくなり集塵効率が低下
してしまうからである。When the volume resistivity value of this semiconductive layer is less than 10 10 Ωcm,
Not only is the leakage current too large to cause spark discharge and ignition, and it is also not preferable because it causes deterioration of the insulation coating in a short period of time.If the leakage current exceeds 10 17 Ωcm, the leakage current will disappear and particles in the gas will disappear. This is because the electric charge cannot be charged to the inside and the dust collection efficiency decreases.

ー（株）の押出成形用、射出成形用樹脂がある。The use of ethylene ethyl acrylate copolymer resin as the semi-conductive layer is because the volume resistivity of the general synthetic resin and the carbon-added resin changes with time and gradually increases.
Although this may cause dielectric breakdown, it was found that this resin has a small change over time and is stable. Since the volume resistivity of this resin changes depending on the content of ethyl acrylate, a resin having a desired resistance within the above range can be obtained. Further, this resin has good contact with both the conductive tape and the insulating coating, and can be easily manufactured by thermal bonding. Commercially available products of this resin include, for example, resins for extrusion molding and injection molding manufactured by Nippon Unicar Co., Ltd.

Those exceeding Ω · cm are used.
