Embodiment 1

[0021] The core wire is composed of 4 bundles of 12K polyacrylonitrile carbon fiber monofilaments; the far-infrared heating is prepared according to the above preparation method. In the first step, the glycerin coating solution used is formulated with 25% glycerin, 10% ethanol, and 65% pure water. The part of the core wire immersed in the glycerin coating liquid passes through at a speed of 0.5 meters per minute, dried at 90°C, and stays in an oven for 3 minutes; then thickens the polyethylene protective cover of 0.45mm.

Embodiment 2

[0023] The core wire is composed of 6 bundles of 12K polyacrylonitrile carbon fiber monofilament; the far-infrared heating is prepared according to the above-mentioned preparation method. In the first step, the glycerin coating solution used is formulated with glycerin 35%, ethanol 10%, and purified water 55%. The part of the core wire immersed in the glycerin coating solution passes through at a speed of 1 meter per minute, is dried at 110°C, stays in an oven for 3 minutes, and then thickens to a polyethylene protective cover of 0.80 mm.

Embodiment 3

[0025] The core wire is composed of 12K polyacrylonitrile carbon fiber monofilament. The far-infrared heating is prepared according to the above preparation method. In the first step, the glycerin coating solution used is made up of 30% glycerin, 15% ethanol, and 55% pure water; The part of the thread immersed in the glycerin coating liquid passes through at a speed of 0.7 meters per minute; it is dried at 100°C and stays in an oven for 3 minutes; then the protective cover of the filament non-woven fabric is widened by 20mm.

Abstract

The invention relates to a remote infrared heating line and relative preparation. Wherein, said heating line is formed by core line coated by glycerin and the protective muffle outside the core line. And the preparation comprises; (1) coating glycerin layer; (2) sheathing protective muffle. When two ends of said heating line are connected to the direct or alternative current power, the core line will heat quickly, which is the heat radiation of remote infrared light; the thermal effect of core line is higher than other materials, while the wavelength of said remote infrared light is 8-15micrometer, near to the wavelength 9micrometer of human, which can be absorbed by body.

Description

Technical field [0001] The invention relates to an electric heating material, in particular to an electric heating wire, in particular to a heating wire that generates far infrared rays when energized. Background technique [0002] The required heat generated by the combustion of coal, fuel oil, etc. will pollute the environment. Converting electrical energy into heat energy can effectively solve this problem. Currently used electrothermal materials for converting electrical energy into heat energy include metal, ceramic, synthetic materials, etc., but they generally have the disadvantage of insufficient thermal efficiency. Some electric heating materials can produce far-infrared rays, which are used to make various health treatment instruments, but they also have the disadvantage of low thermal efficiency; some are limited by materials, and the treatment is limited to local areas, which is inconvenient to use; some emit far infrared rays. The wavelength of infrared is not comple...
