The bacterium for going out all and virus；Ultraviolet sterilization does not add any chemical substance, will not generate in use any secondary
Pollution.Traditional sterilization method is all to be sterilized using the strong oxidizing property of chlorine or ozone, and disinfectant itself is all to belong to
In severe toxicity, combustible material, and ultraviolet tube is then not in such security risk.So being replaced with ultraviolet sterilization traditional
Chemical sterilization has become present main trend.And cold cathode uv lamp pipe is more superior than hot cathode in performance, cold yin
It is great to have the advantages such as long-life and resistance to on-off times, excite filament to discharge electronics by high pressure, electric current is small, and calorific value is low, these
It is all the guarantee of long-life and resistance to on-off times.
At present in the packaging technology of cold cathode uv lamp, increases auxiliary exhaust ports mostly and be vented, current technique
For among quartz glass tube or filament sealing part is with a duck eye is burnt, and reconnects a segment process pipe, the good lamp of both ends clamp
After silk, mercury item is put by process duct, gaseous mixture is filled with after being vented by process duct, is then sealed after Cutting process pipe again
Mouthful.Presently, there are many problems for such technique:
1., matter of utmost importance the phenomenon that being exactly that air-tightness is bad at exhaust air technique pipe, being easy to appear gas leakage；
2., secondly increase a segment process pipe, this segment process pipe be it is useless, auxiliary operation also needs to tear open after completing
Fall, for ultraviolet lamp fluorescent tube itself and be not present, so indirectly wasting process duct cost.
3., be finally exactly quartz burner problem of appearance, the fluorescent tube made of current technique all can in surface of the light tube
There are a sealings to scab, and influences fluorescent tube appearance, and after scabbing, tube outer wall out-of-flatness influences the assembly of fluorescent tube in the product.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of cold cathode uv lamp packaging technology of exhaust-pipe-free,
In solving current cold cathode uv lamp pipe air-tightness present on encapsulation is bad, process costs waste, unsightly etc. bad
Phenomenon.The cold cathode uv lamp of technique production through the invention, has air-tightness good, simple process and low cost, beauty etc.
