<p>The present invention relates to a ceramic-coated heater in which the outer surface of a heater rod is coated with ceramic to improve the physical properties thereof including durability, corrosion resistance, and the like, thereby enabling the heater to be used in water or air. The outer surface of the heater rod is coated with a ceramic composition to which an acrylic corrosion resistant wax is added, thereby strengthening the bonding force of the coating layer film, and thus improving the physical properties thereof including durability, corrosion resistance, and the like to enable the heater to be used in water. In addition, the film of the coating layer is not decomposed even when the heater is heated to a temperature of 260°C or higher to heat air, thereby enabling the heater to be used in water or air and to be applied to a variety of home appliances including a drum washer, a steam iron, a heater, and the like. The outer surface of the heater of the present invention is coated with a ceramic composition obtained by mixing high thermal conductive ceramic such as boron nitrate, ²-alumina and the like and far infrared ray-radiating ceramic, thereby improving thermal conductivity and wear resistance, and thus enabling high thermal conductivity by using less current and thereby reducing energy consumption. Therefore, the ceramic-coated heater of the present invention can be utilized in a wide variety of industrial fields.</p> |
