Description
Technical field
The present invention relates to glassware technical field, more particularly, to a kind of light source glass with special chemical stability and
Preparation method.
Background technique
In recent years, the progress with science and technology, electric light source have been widely used for architectural lighting, light skill with the development of economy
The every field such as art, electronic information industry, auto industry, national defence and health care.Domestic electric consumption on lighting institute in electricity consumption
The ratio accounted for also improves year by year.Therefore, developing efficient, energy-saving and environmental protection and electric light source products with long service life becomes photograph
The target that bright industry is laid siege to.Main material of the glass as manufacture electric light source device, energy-saving and environmental protection with electric light source and
Service life is closely bound up.Although China is the big country of electric light source glass production, but is not power, technology is also opposite to be fallen
Afterwards, the electric light source glass class of production and quality level are all relatively low.Meet the electric light of the high-quality of European Rosh standard at present
It is also mainly grasped by external several big electric corporation with glass formula in source.Therefore, develop possess independent intellectual property right and
The good electric light source glass for meeting European & American Market environmental protection has very important significance.
It is well known that borosilicate glass chemical property is stablized, water-fast and acid-proof alkaline is excellent, especially has good
Mechanical strength and heat-resisting shock property are made by the glass bulb, glass-tube and glass rod etc. as electric light source glass processing at various specifications
It is lighting source shell its excellent physicochemical property in addition to shielding, can also prevents influence of the environment to lamp, while the glass
Glass product has visible light high transmittance, and has uvioresistant and anti-exposure performance, without harmful elements such as lead, so extensively
For environment temperature be -20 DEG C~40 DEG C road, highway, airport, harbour, dock, station, square, street intersection,
Industrial and mining enterprises, park and garden illumination etc. are local.Also electric light source hard glass bulb preferred material is classified as by State Administration of Light Industry, and made
DGW233 type and DGW240 type electric light source glass main technical detail QB/T2451-99 standard are determined.But with use scope
Expanding, existing Pyrex light transmittance, the performance indicators such as water resistance are no longer satisfied the requirement of current light source glass,
At present about more one level higher than K9 glass transmission rate, and the light source glass that the indexs such as water resistance, acid resistance and density are more excellent
Glass becomes the glass types that major light source enterprise is badly in need of.
In the prior art, some tabula rasa glass optics properties are preferable, but the glass alkaline earth metal content is high, frit
Short, density is big, poor chemical stability, is not suitable as the use of light source glass.Lead, arsenic are free of in glass also, without corresponding dirty
Dye, conducive to environmental protection and improves working conditions, but barium content is high, corrodes seriously the refractory material of kiln, and glass lacks
It falls into and is difficult to control.Diboron trioxide (B in glass also2O3) content height, the compound volatilization of melting process boron is serious, glass
Viscosity is big, and glass melting temperature is high, and operating condition is stringent.The glass product have visible light high transmittance, and have uvioresistant and
Anti-exposure performance is free of harmful element, but such glass expansion coefficient is low, is simply possible to use in metal sealing field, it is impossible to be used in glass
Glass light source.Preparation method includes the steps such as pretreatment of raw material, high temperature melting, ultrasonic vibration de-bubble, action of forced stirring and material leakage molding
Suddenly, the silicate glass of bubble-free, calculus and striped is finally obtained, gained glass has good heat shock resistance, anti-high energy spoke
According to and the features such as chemical stability, especially anti-rubidium steam is had excellent performance, and has fully met anti-rubidium steam glass bulb, anti-sodium steams
