Abstract
The invention discloses the preparation technology of a kind of quartz ampoule, the preparation of described quartz ampoule includes following alloy, and proportioning is aluminium oxide 0.3% 0.5%, boron oxide 0.7% 0.9%, calcium 0.0008% 0.001%, Barium monoxide 0.5% 0.7%, sodium oxide 0.03% 0.05%, potassium oxide 0.03% 0.05, lithium oxide 0.01% 0.02%, titanium oxide 0.01% 0.1% and silicon dioxide 96% 98%.The electric light source series products made of the quartz ampoule of the present invention, in the case of using temperature less than 700 DEG C, not only service life is long, the degree of oxidation of electrode can also be reduced, improve the service life of light source, the TiO2 of doping can make quartz ampoule more preferable can cross the ultraviolet of below filter section early 250 μm, reduces the injury to human body, alternative common quartz ampoule.
Description
Technical field
The present invention relates to the preparation technology of a kind of quartz ampoule, particularly relate to the preparation method of a kind of low melting point transparent quartz tube.
Technical background
There is following defect in the preparation technology of quartz ampoule of the prior art: the purity of raw material quartz sand is high, originate in doping unreasonable, the fusing point of product is high, it is not easy to production and processing, there is also, in product uses, the phenomenon that can aoxidize, the scope being suitable for is narrower, portioned product ultraviolet Wu's filter effect to producing.When being applicable to electric light source products use, service life is short, and harm ray produces, and affects surrounding population healthy, and leverages the quality of electric light source products.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that the preparation technology of a kind of antioxidation, effectively filtration 250 μm following band ultraviolet quartz ampoule.
For reaching above-mentioned purpose, the present invention is achieved through the following technical solutions:
A kind of preparation technology of quartz ampoule, the preparation of described quartz ampoule includes following alloy, and proportioning is aluminium oxide 0.3%-0.5%, boron oxide 0.7%-0.9%, calcium 0.0008%-0.001%, Barium monoxide 0.5%-0.7%, sodium oxide 0.03%-0.05%, potassium oxide 0.03%-0.05, lithium oxide 0.01%-0.02%, titanium oxide 0.01%-0.1% and silicon dioxide 96%-98%.
Described alloy, the hydrofluoric acid dips that concentration is 5% 10 minutes, takes out alloy clear water and rinses, dries, and temperature during alloy melting is 2000-25000 DEG C, draws out pipe and processes at deshydroxy, and deshydroxy temperature is 1200-1300 DEG C, 3-4 hour deshydroxy time.
Compared with prior art, have the beneficial effect that the electric light source series products made of the quartz ampoule of the present invention, in the case of using temperature less than 700 DEG C, not only service life is long, can also reduce the degree of oxidation of electrode, improve the service life of light source, the TiO2 of doping can make quartz ampoule more preferable can cross the ultraviolet of below filter section early 250 μm, reduce the injury to human body, alternative common quartz ampoule.
