Abstract
The present invention relates to an oxidation type neon tube electrode rust-resisting method, including the following steps: before the oxidation type neon tube electrode finished product is packaged, placing said electrode into back oven to roast it, roasting temp. is 400-450 deg.C and roasting time is 1-4 min., then using sealing material to seal the opening of the electrode. Said invention can ensure that when the neon tube is manufactured, its interior does not produce impurity, so that it can raise the quality of neon tube.
Description
Technical field
The present invention relates to neon tube electrode, particularly the rust-proofing method of oxidation type neon tube motor.
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 its metal part sub-electrode chamber (see figure 1) surface oxide layer 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 the trickle globule of H2O, make stable FeO oxide layer oxidation once more, become and floated over the extremely unsettled Fe3O4 of FeO oxidized surface, be commonly called as yellow rust staining.As everyone knows, the quality of neon lamp tube is except vacuum degree 1*10
-Outside 2 the assurance, 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.
The utility model content
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 utility model 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 that adds the pyrocondensation sheet after the electrode oven dry;
Fig. 3 is the schematic diagram that adds anti-rust cap after the electrode oven dry.
Implement novel execution mode
As shown in Figure 1, oxidation type neon tube electrode is by iron plate moulding rear oxidation, fixedly Dumet wire then high temperature and glass tube sealing-in dress lead-in wire 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 Fe3O4 oxide that floats over oxide layer FeO surface, 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, form small globule H2O, through behind the certain hour, autoxidation generates Fe3O4 once more, and 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, and seal oxidation type neon tube electrode glass tube opening part immediately, isolated damp atmosphere enters, and the burning part that just can not cause neon tube electrode naturally autoxidation once more generates Fe3O4.So, 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 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 that prevents, autoxidation generates Fe3O4 (seeing Fig. 2 and Fig. 3) once more.
