The method can be applied in scaled productions.
Description
Technical field
The invention belongs to power saving fluorescent lamps glass and preparation field thereof, the unleaded high permeability power saving fluorescent lamps of particularly a kind of low sodium glass and preparation method thereof.
Background technology
Present power saving fluorescent lamps all is to be used for the Na-Ca-Si system glass; 80% of present energy-conservation lantern pane adopts common soda-lime glass (being commonly called as lime material glass); The sodium amount that contains of common soda-lime glass is 16-17%; And external several famous illumination company all develops the electricity-saving lamp glass of different size, and it contains the sodium amount and all is higher than 5wt%.
Sodium ion is the important component part in the silicate glass, and it is that the glass melting temperature and the electric property aspect that reduce glass have very remarkable advantages.But electricity-saving lamp with Glass tubing in since Glass tubing in contain the highly compressed mercuryvapour, in use with glass in sodium ion can react, reaction formula is following:
The sodium amalgam that reaction generates will be deposited on and form black solid on the Glass tubing, and often see in our life that Here it is fluorescent lamp and electricity-saving lamp are in the reason of using the later stage usually to turn black.Electricity-saving lamp factory prevents through on Glass tubing, adding one deck coating at present, but one side increases technology one, and coating is lower for the work-ing life on the long-time high temperature high-voltage at present simultaneously, and the quality of this coating indicates the life-span of electricity-saving lamp to a certain extent.In addition, though coating is transparent, its transmitance is low than glass, has also reduced the optical throughput and the quality of electricity-saving lamp.
Summary of the invention
Technical problem to be solved by this invention provides the unleaded high permeability power saving fluorescent lamps of a kind of low sodium glass and preparation method thereof, and this glass sodium content is low, the work-ing life that can improve electricity-saving lamp, and also transmitance is up to 92%, and its preparation method is simple.
