Abstract
The present invention relates to an oxidation type neon lamp electrode rust-preventing method which comprises the following steps: the electrodes of a neon lamp are put in a baking oven and are baked before the finished products of the electrodes of the oxidation type neon lamp are packed, and baking temperature is from 400 to 450 DEG C; baking time is from 1 to 4 minutes; the openings of the electrodes are sealed by sealing materials. The present invention prevents the oxidation of the surface of an electrode chamber because of moisture in moist weather and moist seasons and ensures that no impurity is generated in the manufacture of a lamp tube of the neon lamp, and the present invention also enhances the quality of the neon lamp.
Description
Technical field
The present invention relates to neon tube electrode, particularly the rust-proofing method of oxidation type neon tube electrode.
Background technology
Oxidation type neon tube electrode is since coming out, up to today, in relative humidity bigger area and season, electrode gets rusty and is perplexing neon light in the industry always, neon tube electrode manufacturer, and the measure of generally taking is that high humidity stops production season, the high humidity area does not produce oxidation type neon tube electrode, in a single day oxidation type neon tube electrode in high humility production in season gets rusty, and neon tube electrode is produced house, generally all does and scraps processing.And the rainbow electrode of some neon light manufactories deposit in the high humility area, find to get rusty season is that what is called is saved cost, do not go for and scrap processing, continue to use the oxidation type neon tube electrode that gets rusty, manufacture neon light tube, this kind neon light tube quality can not get guaranteeing at all.Because the oxidizing electrode surface oxide layer of its metal part sub-electrode 2 (see figure 1)s of oxidation type neon tube electrode should be layer of even FeO through the normal oxidation treatment surface, this kind oxide is more stable, and in high humility area season, the surface condensation of above-mentioned more stable FeO oxide layer H
2The trickle globule of O makes stable FeO oxide layer oxidation once more, has become to float over the extremely unsettled Fe of FeO oxidized surface
3O
4, be commonly called as yellow rust staining.As everyone knows, the quality of neon lamp tube is except vacuum degree 1 * 10
-2Outside the assurance of P, under pure pure condition, conditions such as filling with inert gas are just guaranteed in the fluorescent tube.Therefore oxidation type neon tube electrode gets rusty and directly endangers the quality of neon light industry and neon light.
Summary of the invention
For achieving the above object, oxidation type neon tube electrode rust-resisting method comprises step:
Before the oxidation type neon tube electrode finished product packing, neon tube electrode is put into baking box and toasts,
Baking temperature is 400--450 ℃,
Stoving time is 1-4 minute;
With encapsulant the opening part of electrode is sealed.
The present invention has prevented the electrode chamber surface because of the oxidation that humidity causes at wet weather and wet season, and inside does not produce impurity when guaranteeing when making neon light fluorescent tube, has improved the quality of neon light.
Description of drawings
Fig. 1 is the neon tube electrode schematic diagram;
Fig. 2 is the schematic diagram of adding a cover the polyvinyl chloride anti-rust cap after the electrode oven dry;
Fig. 3 is the schematic diagram that adds anti-rust cap after the electrode oven dry.
Embodiment
As shown in Figure 2, oxidation type neon tube electrode is by iron plate moulding rear oxidation, be the semi-finished product oxidizing electrode, fixedly Dumet wire 3 then high temperature and the sealing-in of electrode glass bulb dress lead-in wire 4 finish, in the high humility area, high humility season, the surperficial FeO oxide layer of electrode chamber (metal part) oxidation once more generates the extremely unsettled Fe that floats over oxide layer FeO surface
3O
4Oxide, because in the high humility area, high humility season, in making the oxidation type neon tube electrode process, Celsius more than 1000 ℃ behind the high intermediate temperature sealing, neon tube electrode is in dropping to the normal temperature process gradually, airborne height moisture is the electrode chamber watch crystal inside pipe wall of apposition after burning at leisure, forms small globule H
2O, through behind the certain hour, autoxidation generates Fe once more
3O
4, getting rusty floats over the electrode chamber surface.So, if under the environment of higher temperature, oxidation neon tube electrode finished product is in the short time, baking is dry, seal the electrode glass bulb opening part of oxidation type neon tube 1 immediately with polyvinyl chloride anti-rust cap 5, isolated damp atmosphere enters, and the burning part that just can not cause neon tube electrode naturally autoxidation once more generates Fe
3O
4So, before the oxidation type neon tube electrode finished product packing, neon tube electrode is put into baking box, baking is 1-4 minute under 400-450 ° temperature, in processing oxidation type neon tube electrode process, the trickle globule oven dry at burning electrode chamber and glass bulb inner surface is applied in suction, and drying time is 2 minutes preferably.And immediately with the opening part that the pvc material anti-rust cap covers electrode is sealed or added a cover to the opening part of electrode as the encapsulant of material contracting with heat, isolated damp atmosphere enters oxidation type neon tube electrode inside, with the highly effective oxidation type neon tube electrode autoxidation generation Fe once more that prevents
3O
4(see figure 3).
