Process of gaseous opalization of light bulbs |
摘要 |
In a process of gaseous opalization a film of silica is formed by an oxidation reaction with a dry gas containing oxygen. Pure oxygen or oxygen diluted in an inert gas, other than nitrogen, may be used. An electric arc is generated by an alternating voltage between 5,000 and 10,000 volts and is directed at a chlorinated silicon compound, entrained by the dry gas containing oxygen, the feeding of which gas carrier does not form silica on the electrodes which generate the arc. This process may be applied to the opalization of incandescent and discharge bulbs of various sizes including tubes and globes of lighting apparatus.
