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 300nμ ultraviolet rays, direct radiation to the eyes will cause severe burns to the eyes; direct radiation to human skin will cause human epidermal cells to mutate, and in severe cases will induce skin cancer

Embodiment 1

[0026] 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 composed of 25% to 30% of a powder mixture and 65% to 75% of an adhesive solution. Use water-soluble resin such as melamine formaldehyde resin, wherein the content of powder mixture includes 29.2% of rare earth elements, 30% of high-temperature pigment, titanium dioxide includes ordinary titanium dioxide and nano-titanium dioxide, ordinary titanium dioxide is 10%, nano-titanium dioxide is 0.8%, frit 30% %, ground to above 900 mesh; after stirring the above-mentioned powdery mixture and binder solution evenly, through high-temperature physical vapor deposition process, they are compounded on the surface of the heating tube to form a composite film 2, the thickness of the composite film is 5-25μ, and the ~150°C drying, 800°C~1050°C sintering and curing. The ra...

Embodiment 2

[0029] In the above-mentioned formula, the composition of its film is made up of powdery mixture 30% and adhesive solution 70%. 2%, rare earth element 30%, frit 30%.

[0030] Such as figure 2 - As shown in 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.

[0031] In the above embodiment, trace amounts of zirconium oxide, zinc oxide, boron oxide, and silicon oxide can also be added to the powdery mixture, the content of which is less than 1%, correspondingly reducing the proportion of high-temperature pigments or ordinary titanium dioxide or rare earth elements. content ratio.

[0032] The electric heating tube of the present invention can be used for halogen tubes, ultraviolet lamp tubes, quartz electric heating tubes or metal tubes.

Abstract

The present invention discloses a rare earths nano titanium film electric heating tube. It features said rare earths nano titanium film consisting of powder mixture and adhesives solution, wherein powder mixture including rare earth element 25-30 per cent, titanium oxide 5-35 per cent, high temperature pigment 5-35 per cent, and fusion cake 25-30 per cent. In said film composition, powder mixture 25-30 per cent and adhesives solution 70-75 per cent is stirred uniformly, through high temperature PVD technology, compounding on heating tube surface to form complex film, then through drying sintering solidification to obtain said invented film. Above-mentioned rare earths nano titanium film electric heating tube has high thermal efficiency and good using effect.

Description

technical field [0001] The invention relates to an electric heating element, in particular to a rare earth nanometer titanium film electric heating tube. Background technique [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: since the working temperature of the tungsten wire of the halogen tube is about 2200 ° C, most of its spectral distribution is in the visible light range, and there are many light effects. Due to the thermal effect, the heat conversion efficiency is low, and when it is used for electric heating, its glare is strongly irritating to human eyes, causing eye fatigue and discomfort. The radiation spectrum of the halogen tube contains about 300nμ 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 ind...
