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.
