Problems solved by technology

[0002] Halogen electric heating tubes are widely used in the field of electric heating, which have the advantages of low cost and fast start-up, but also have serious defects: because the working temperature of the tungsten wire of the halogen tube is 2200°C Left and right, most of its spectral distribution is in the visible light range, the light effect is more than the thermal effect, and the heat conversion efficiency is low. It is used for electric heating, and its glare is strongly irritating to human eyes, causing eye fatigue and discomfort.
The radiation spectrum of the halogen tube contains about 300nm of ultraviolet rays, direct radiation to the eyes will cause severe burns to the eyes; direct radiation to the human skin will cause human epidermal cells to mutate, and in severe cases will induce skin cancer

Embodiment 1

[0028] The rare-earth nano-titanium film electric heating tube of the present invention is compounded with a rare-earth nano-titanium film 2 on the surface of the electric heating tube 1, and the composition of the film is prepared from a powder mixture of 25% to 30% and an adhesive solution of 65% to 75%. The agent adopts a water-soluble resin solution such as melamine formaldehyde resin solution, wherein the content of the powder mixture includes 29.2% of rare earth elements, 30% of high-temperature pigments, and titanium dioxide includes ordinary titanium dioxide and nano-titanium dioxide, ordinary titanium dioxide is 10%, and nano-titanium dioxide is 0.8%. 30% frit, ground to more than 900 mesh; after stirring the above powder mixture and binder solution evenly, through high-temperature physical vapor deposition process, composite on the surface of the heating tube to form a composite film 2, the thickness of the composite film is 5-25 μm, It is formed by drying at 100°C to...

Embodiment 2

[0031] In the above formula, the composition of the film is prepared from 30% of powder mixture and 70% of binder solution. In the powder mixture of the composition of the film, 6% of high-temperature pigment, 32% of ordinary titanium dioxide, and 32% of nano-titanium dioxide 2%, rare earth elements 30%, frit 30%.

[0032] As shown in Figure 2-Figure 4, the rare earth nano-titanium film is composited on the surface of the tube in intervals, forming various intervals such as horizontal intervals, oblique intervals, and longitudinal intervals.

[0033] In the above embodiment, traces of zirconium oxide, zinc oxide, boron oxide, and silicon oxide can also be added to the powder mixture, the content of which is less than 1%, which reduces the amount of high-temperature pigments or ordinary titanium dioxide or rare earth element-containing substances accordingly. The proportion of the content can be.

[0034] The electric heating tube of the present invention can be used for halog...
