Abstract
The utility model relates to a fluorescent tube whose inner wall is coated, which relates to the fluorescent lamp field, in particular to a fluorescent tube which is coated with the titanium dioxide. The inner wall of the lamp tube of the utility model is coated and membrane is formed with armorphous phase nanometer titanium dioxide water weak liquor, the chance that sodium atoms run to the surface of the fluorescent power particles through heat diffusion is reduced, and generation of black sodium amalgam is effectively reduced, and the lumen maintenance rate of the fluorescent tube is increased by 6% to 8% than an ordinary alumina coating, thereby the service life of the lamp tube is greatly improved.
Description
Technical field
The present invention relates to the fluorescent tube field, particularly a kind of fluorescent tube of inside coating.
Background technology
The economic and technique level that is limited to present China, though the price of the glass-tube material that China's manufacturing compact fluorescent lamp tube is used is lower, but the inferior quality inferior quality mainly shows two aspects: the one, and it is higher to contain the sodium amount, the 2nd, the photic melanism of glass-tube is serious, densification along with fluorescent lamp, the tube wall load of fluorescent tube further improves, and the working temperature of fluorescent tube also improves constantly, and the thermal diffusion of sodium ion in the glass has been quickened in the raising of glass-tube temperature.These sodium ions will be from the glass diffusion inside to glass-tube inner surface, and and electron recombination there, form neutral sodium atom.To go to the surface of fluorescent powder grain by thermal diffusion again at the sodium atom that the glass-tube inwall forms, and react, generate the sodium amalgam of black at the surface and the mercury atom of fluorescent powder grain.Thereby the excited ultraviolet that it is 253.7nm to the surperficial wavelength of fluorescent powder grain that the black sodium amalgam that generates on the fluorescent powder grain surface will absorb irradiation on the one hand makes fluorescent powder grain can not be subjected to exciting fully; On the other hand, the black sodium amalgam on the fluorescent powder grain surface will make the lumen output of lamp reduce.By top analysis as can be known, the sodium element in the glass is to make one of principal element that the lumen depreciation of lamp descends, but the effect of the aluminium oxide inside coating that generally uses now and not really desirable.
Summary of the invention
1, uses aluminum oxide coating layer in the prior art in order to solve, the black sodium amalgam produces more, the lumen output of lamp is reduced, the problem of lumen depreciation difference, the technical scheme that we provide is with unformed phase nano-titanium dioxide water diluent material tube inner wall to be carried out coating, thus the film layer structure that forms with tube inner wall glass, and unformed phase titanic oxide coating layer thickness is for being generally 0.8-1.3 μ m, the particle diameter of nanometer titanic oxide material is 10-80nm, preferably 10-50nm.Water diluent material with unformed phase nano-titanium dioxide carries out coating to tube inner wall, form the interior tube inner wall glass that is with tube inner wall, outer is the film layer structure of coating of titanium dioxide, because it is stable that nano titanium oxide has chemical property, nonirritant, no sensitization, good with the base-material compatibility, long action time, shielding comprehensively, particle is ultra-fine evenly, dispersed characteristics such as good, with in the prior art with aluminum oxide coating layer relatively, sodium atom is difficult to go to by thermal diffusion the surface of fluorescent powder grain, surface and mercury atom reaction at fluorescent powder grain, therefore the black sodium amalgam significantly reduces, and the lumen depreciation with the fluorescent tube of nanometer titanic oxide material coating has increased 6-8% than common aluminum oxide coating layer, thus life-span of the lamp of raising greatly.Wherein the particle diameter of titanic oxide material is 10-80nm, and preferably 10-50nm is rare to 4-9%, as adding certain amount of dispersant and bonding agent in the needs suspension with pure water.Evenly be coated with the back oven dry and also can repeat to be coated with, coating layer thickness L is 0.8-1.3 μ m.Method of measurement can be with maneuverable following method, though not too accurate, very practical.Select the fluorescent tube diverse location can be measured fluorescent tube fragment 5-10 sheet, measure each piece surface area S, do following nanometer titanic oxide material check weighing amount W, proportion F (not considering when adding some auxiliary agents, to cause the variation a little of proportion), measure coating layer thickness L in view of the above, be Ln=Wn/Sn*F (n is 1-10), final L=L1+L2+...L10/10.Certainly also available known advanced person's optics or electronics or chemical method. (as please the test of national non-ferrous metal quality supervision and test center)
