Abstract

The present invention relates to a carbon heater in which a center line (16b) is centered without being eccentric in a heat-resistant glass tube (12) by a tension support part (19) elastically supporting the heat-resistant glass tube (12), so that a carbon fiber yarn (11) does not make direct contact with an inner periphery of the heat-resistant glass tube (12), thereby minimizing damage caused by the contact when the carbon fiber yarn (11) generates heat. More particularly, in the carbon heater, the center line (16b) is prevented from being fluctuated to left and right as well as up and down through the tension support part (19), so that when a pressing part (12a) is provided at a center of a first connection terminal (13a) and a second connection terminal (13b), even if work is performed in a state in which the heat-resistant glass tube (12) stands upright, the pressing part (12a) is prevented from being lowered from the heat-resistant glass tube (12) by weights of the carbon fiber yarn (11), an insulating tube (17), and the center line (16b), and thus the pressing part (12a) is provided much more easily, thereby ensuring productivity.

At this time, the crimped portion 12a to be thermally pressed must have a clearance, and the first lead wire 14a And the second lead line 14b are also inevitably exposed to the gap. In this case, the light leakage, that is, the infrared rays, must escape through the gap.

In the present invention, the infrared shielding coating portion 15 coated on the surface of the crimping portion 12a and the gap around the first lead wire 14a and the second lead wire 14b so as to thoroughly block the infrared rays Thereby maximizing the service life of the binding means 20 made of rubber, silicone or synthetic resin.

Especially, it is very stable with high hiding power not dissolving in acid. It is excellent in weatherability and chemical resistance, And is effective as an insulator. In the present invention, 10-15 wt% of titanium dioxide is applied. When it is 10 wt% or less, the acid is applied to the acid If the dissolving hiding power is lower than 15 wt%, mixing with the acrylic resin is not performed well, and in the present invention, 10 to 15 wt% of titanium dioxide is applied.

In the present invention, the graphite is applied in an amount of 3 to 7 wt%. When the amount of graphite is less than 3 wt%, it is difficult to block the infrared rays. When the amount of the graphite is more than 7 wt% In the present invention, 3 to 7 wt% of graphite is applied.

As a result, a phenomenon of cracking occurs after curing because of excessively hardness. Therefore, in the present invention, 6 to 8 wt% of calcium carbonate is applied.

Sodium silicate adjusts the mixed viscosity of acrylic resin, titanium dioxide, graphite, silica beads, calcium carbonate and carbon. For example, when the concentration is increased, the viscosity is raised. When the temperature is increased during mixing, the viscosity is lowered, In the present invention, 4 to 7 wt% of sodium silicate is applied. When the amount is less than 4 wt%, the viscosity is weakened to slow the curing after coating. When the amount is 7 wt% or more, In the present invention, 4 to 7 wt% of sodium silicate is applied.

In the present invention, carbon is applied in an amount of 5 to 7 wt%, and when it is 5 wt% or less, infrared rays are difficult to block, and when it is 7 wt% or more, carbon acts as a conductor, 7% by weight.
