Solid mercury for manufacturing lamp

Abstract

The invention relates to solid mercury for manufacturing a lamp and belongs to the technical field of energy-saving fluorescent lamp tube manufacturing materials. The solid mercury for manufacturing the lamp comprises, by mass, 50%-85% of Bi, 1%-10% of Ag, 10%-35% of Hg, 0.5%-5% of Sn and 0-3% of Sb. Multi-element eutectic alloy is formed by Bi atoms, Ag atoms, Sn atoms, Sb atoms and part of Hg atoms; the addition of the Sn and the Sb improves the grain structure of solid amalgam, the strength of the multi-element eutectic alloy can be enhanced, and the remaining part of free mercury atoms exist between crystal lattices of the multi-element eutectic alloy; after the solid mercury is used for manufacturing the energy-saving fluorescent lamp, a characteristic curve similar to pure mercury can be obtained, and the curve of the climbing speed that a lamp tube is lighted approaches the liquid mercury characteristic curve. According to amalgam, mercury loss cannot occur at the normal temperature, the abundance mercury quantity in the lamp tube is relatively stable, the lighting speed of the lamp tube is guaranteed, and the lamp tube is prevented from changing color after being used for a long time.

Description

technical field [0001] The invention relates to an alloy material used for manufacturing energy-saving lamps and electrodeless lamps, in particular to an amalgam. Background technique [0002] Amalgam is a kind of amalgam material, which can be used to make energy-saving lamps, electrodeless lamps and ultraviolet germicidal lamps, etc., especially solid mercury (solid amalgam), because it is solid, it can be quantitatively made into particles, and the surface of the particles is not easy to rust. Liquid mercury is released, the particles do not stick to each other, and the damage to the environment and lamp workers is relatively small. At the same time, it has good luminous characteristics, and the mercury pressure is at the best value of 0.8Pa. The highest light efficiency can be obtained, and it can directly replace liquid mercury. It is used to make lamps and is an energy-saving and environment-friendly product.
