Pyongyang, July 15 (KCNA) — Far-infrared refractory materials have been widely used in economic sectors in the Democratic People’s Republic of Korea.
The heat-insulating materials, which radiate heat well while saving electricity and coal, are used in making insulating bricks, heating boards and heat-radiating tiles.
As they sharply raise thermal efficiency per unit hour, the insulating bricks are suitable for electric stoves of restaurants, heat treatment furnaces and forging furnaces.
They can save 50 percent of electricity in case of electric stove.
The steam bathhouses, built with the heating boards and heat-radiating tiles, ensure high temperature and lift far-infrared ray intensity up to 80 percent while economizing 30 percent of electricity, 40 percent of coal and 60 percent of wood.
The porous boards and tiles with a strong adsorptive power remove unpleasant smell and moisture from the steam bathhouses.
