Abstract
The invention discloses a production process for a gas discharge tube. The production process comprises step one, connecting an exhaust pipe with the tube; step two, fusing solid spherical transitional glass at one and/or two ends of the tube in a high-temperature environment, wherein the expansion coefficient of the transitional glass is between the expansion coefficient of an electrode and the expansion coefficient of the tube; step three, blowing the solid spherical transitional glass into a hollow tube with the inner diameter larger than the diameter of the electrode in a high-temperature environment; step four, inserting the electrode into the hollow tube and sealing the middle of the electrode in the hollow tube. According to the production process, the solid spherical transitional glass is fused at two ends of the tube firstly, then, the spherical glass is blown into a tubular shape through the exhaust pipe, the electrode is inserted and sealed into the tube, the whole process is simple and rapid, the middle of the electrode is completely covered with the transitional glass with the expansion coefficient matched with the electrode, and air leakage can be avoided after expansion with heat.
Description
Technical field
The present invention relates to a kind of production technology of gas discharge lamp tube.
Background technology
In the gas discharge lamp tube production process, because electrode material is different with the expanded by heating coefficient of hyaline-quartz material, its junction phenomenon that easily leaks air, can't use fluorescent tube after being heated.In order to improve the problems referred to above, in the fluorescent tube production process, elder generation applies transitional glass coating or the functionally gradient material (FGM) layer of one deck coefficient of expansion between quartz material and motor at electrode surface, and then it is connected with glass lamp, thereby avoids the generation of the problems referred to above.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the gas discharge lamp tube production technology that a kind of cost is low, coefficient of safety is high.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of gas discharge lamp tube production technology comprises the following steps:
Step 1 is connected to blast pipe on fluorescent tube;
Step 2 is melting solid spherical transitional glass at an end and/or the two ends of fluorescent tube under hot environment, the coefficient of expansion of described transitional glass is between the coefficient of expansion of electrode and fluorescent tube;
Step 3 is blown out internal diameter to solid spherical transitional glass greater than the hollow pipe of electrode diameter under hot environment;
Step 4, in hollow pipe electrode insertion and with the middle part sealing by fusing of electrode in hollow pipe.
In the present invention, in step 1, the blast pipe welding is on fluorescent tube.
In the present invention, in step 2, deliver to the end of fluorescent tube after transitional glass is softening under hot environment, and then the transitional glass of lamp tube end is fired until be melt into spherical.
In the present invention, in step 2, the diameter of described spherical transitional glass is greater than the diameter of fluorescent tube.
In the present invention, the inner and outer diameter of hollow pipe is corresponding with fluorescent tube.
In the present invention, in step 3, gas enters in fluorescent tube and with transitional glass by blast pipe and blows out hollow pipe.
The invention has the beneficial effects as follows: the present invention is first melted solid transitional glass ball at the two ends of fluorescent tube, then by blast pipe, glass marble is blown out tubulose, and then with in the electrode Inserting Tube and sealing by fusing get up, the whole course of processing is simple, quick, and the middle part of electrode is wrapped in the transitional glass that the coefficient of expansion matches fully, and phenomenon can not leak air after expanded by heating, and the direct welding of transitional glass is at the two ends of fluorescent tube, its junction is away from electrode, and connective stability is high, and the fluorescent tube quality is good.
Description of drawings
The present invention is further described below in conjunction with drawings and embodiments:
Fig. 1 is structural representation of the present invention.
Embodiment
With reference to Fig. 1, a kind of gas discharge lamp tube production technology provided by the present invention, it comprises the following steps:
Step 1 is connected to blast pipe 1 on fluorescent tube 2, and namely blast pipe 1 is connected on fluorescent tube 2 by the mode of welding, and this connected mode belongs to prior art, is not repeated herein.
Step 2, melt simultaneously solid spherical transitional glass 3 at the two ends of fluorescent tube 2, the coefficient of expansion of described transitional glass 3 is between the coefficient of expansion of electrode 4 and fluorescent tube 2, optimum is, the coefficient of expansion of the coefficient of expansion of transitional glass 3 and electrode 4 is close, the so-called close meaning is that after electrode 4 and transitional glass 3 were subjected to variations in temperature, its time expansion rate and space expansion rate were all close or identical.In this step, deliver to the end of fluorescent tube 2 after transitional glass 3 is softening under hot environment, and then the transitional glass 3 of fluorescent tube 2 ends is fired until be melt into spherical.In the present embodiment, the temperature of described transitional glass 3 fusings is 1300 ℃, thereby it is liquid spherical that transitional glass 3 just in time is in, and adhesiveness is strong simultaneously, mobility is low, is convenient to processing.
Step 3 is at high temperature blown out hollow pipe to diameter greater than the solid spherical transitional glass 3 of fluorescent tube 2 diameters, and the internal diameter of hollow pipe preferably is bigger than the diameter of electrode 4, and optimum way is that the inner and outer diameter of hollow pipe is all corresponding with fluorescent tube 2.In the present embodiment, gas enters by blast pipe 1 and carries out blowpipe in fluorescent tube 2.
Step 4, in hollow pipe after electrode insertion 4, then hollow pipe is fired until melt, is then adopted the hollow pipe after apparatus for shaping or mould will melt to be made into specific solid shape, thus with the middle part sealing by fusing of electrode 4 in the transitional glass 3 of given shape.
In step 3, can first melt solid spherical transitional glass 3 at an end of fluorescent tube 2, then transitional glass 3 is blown out the rear electrode insertion 4 of pipe and sealing by fusing, and then the other end of fluorescent tube 2 repetition above-mentioned steps, all can reach identical technique effect.
The above is only preferential execution mode of the present invention, as long as within realizing that with basic identical means the technical scheme of the object of the invention all belongs to protection scope of the present invention.
