Electronic powder for energy-saving lamp and electronic powder slurry and preparation method thereof

Abstract

The invention discloses an electronic powder slurry for a super-long-service-life high-power energy-saving lamp, the electronic powder slurry adopts the coprecipitation technology and generates a co-crystallized carbonate crystal through the coprecipitation reaction of carbonate and nitrate; the crystal is taken as the main material of the electronic powder, colloidal solution is prepared by adding solvent, adhesive and electron emission material, and the colloidal solution can provide the substances which are needed for the electron emission as the electronic powder slurry used for the super-long-service-life high-power energy-saving lamp. The electronic powder slurry can solve the problems of easy sputtering, bombardment intolerance and short service life of the electronic powder duringthe using process of the high-power energy-saving lamp and improve the bombardment resistance capacity of the electronic powder. The electronic powder slurry can greatly prolong the service life of the high-power energy-saving lamp, and the service life can be improved by more than 500 percent.

Description

Electronic powder for energy-saving lamps and its electronic powder slurry and preparation method technical field The invention relates to a lighting material, in particular to an electronic powder for a high-power and long-life energy-saving lamp, its slurry and a preparation method. Background technique Electronic powder paste is attached to the fluorescent lamp filament as the cathode emission material of fluorescent lamps. It is an important part of fluorescent lamps and has a decisive impact on the performance (especially life) of fluorescent lamps. Most of the damage to fluorescent lamps is due to the performance of electronic powder. caused by deterioration or failure. The traditional fluorescent lamp electronic powder paste is based on "Fluorescent Lamp Production Process and Technology" "The electronic powder used in fluorescent lamps is made of 56% barium oxide, 38% strontium oxide, 6% calcium oxide and 5% zirconium oxide. production". When used on high-power e...
