Abstract

The invention provides a far-infrared heating ray and a preparation method thereof. The far-infrared heating wire of the present invention is composed of a core wire coated with glycerin and a protective sheath outside the core wire. The steps of the preparation method are as follows: 1) applying a glycerin layer; 2) adding a protective cover. When the two ends of the far-infrared heating wire of the present invention are connected to a DC or AC power supply, the core wire will heat rapidly; the heat is the thermal radiation of the far-infrared rays generated by the core wire when it is powered on; the core wire has higher thermal efficiency than other thermal energy materials, so The far-infrared rays produced have a wavelength of 8-15 microns, which is the closest to the natural wavelength of the human body at about 9 microns, and can be completely absorbed by the human body and transformed into energy in the human body. Therefore far-infrared heating line of the present invention, both can be used for heating, heating, can be used for health care again.

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 which generates far-infrared rays when electrified. Background technique [0002] The required heat generated through the combustion of coal and fuel oil will pollute the environment. Converting electrical energy into heat energy can effectively solve this problem. At present, the electric heating materials used to convert electric energy into heat energy include metal, ceramic, synthetic materials, etc., but there are generally disadvantages of insufficient thermal efficiency. Some electric heating materials can produce far infrared rays, which are used to make various health care 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; The wavelength of infrared rays is not completely suit...
