本発明はシーズヒータに係り、内部の充填絶縁粉末に関

A heating wire 2 with terminal rods 1 connected to both ends is placed in the center of a metal pipe 3, and an insulating powder 4 for ensuring electrical insulation between the metal pipe 3 and the heating wire 2 is subjected to hydration treatment. The twilling agent 5 is added and filled, and then compressed and diameter-reduced, heat treated and molded as necessary, and sealed with silicone rubber or the like to complete the process.

５００００程度である。Furthermore, to explain the water repellency of the water repellent agent 5, the additive conventionally used as this type of water repellent agent is well known as silicone resin, etc., and the heat resistance limit of the sheathed heater is the silicone resin added. It is almost determined by the characteristics of the resin, and is usually up to about 400q0, and even instantaneous is about 50,000.

施例を図面に従って説明する。Therefore, it had the disadvantage of low heat resistance. In addition, the amount of silicone resin added is generally 1 to 5% by weight relative to magnesia powder, but this is because the contact angle with water is about 90 to 11 degrees, so it is difficult to resist loss. In order to improve and stabilize the content, the amount of addition was increased within the range of 1 to 5%. As a result, it also had drawbacks as a sheathed heater, such as a decrease in filling rate and a decrease in heat conduction. The present invention solves the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings.

を行なう。FIG. 2 shows a heating wire 11, a terminal bar 12, a metal pipe 13, an insulating filler powder 14, a heat-resistant hydrating agent 15, and a silicone rubber 16 sealing both ends of the wire. In the manufacturing process of this sheathed heater, first, terminal rods 12 are connected and arranged at both ends of a metal pipe 13 and a heating wire 11, and insulating filler powder 14 and heat-resistant water repellent agent 15 are added and treated in advance for filling. .

It could be used at temperatures of 450 to 5000C compared to 000C, and no deterioration was observed. Also, the contact angle with water is 1
It has a very high molecular weight of 4,500, and has a strong water-repelling power, and sufficient effects were obtained when the amount added was in the range of 0.5 to 3%. Therefore, the smaller the amount added, the lower the cost, the lower the heat conduction, and the more effective it is in terms of processing and properties, such as stabilizing the amount of filling, and basically no heat treatment is required. , straight heaters, non-sintering anchor pipe heaters, etc. can be expanded to other applications. As is clear from the above description, according to the present invention,
As a water repellent agent, use a material with a contact angle of 110 degrees or more with water, such as fluorocarbon, to increase water repellency, and then add the water repellent in an amount of 0.3 to 3%. It has great industrial value, as it requires only a small amount, has excellent processing and properties, such as reduced costs, improved heat conduction, and stabilized filling volume, and has expanded applications because no heat treatment is required.
