Abstract

The invention relates to a mercury release agent with a high mercury release amount and a preparation method of the mercury release agent. The mercury release agent with the high mercury release amount is prepared from components in parts by weight as follows: 45-90 parts of a titanium-mercury alloy Ti3Hg, 10-50 parts of a zirconium-aluminum alloy ZrAl16, 4-12 parts of high-purity Ti powder, 3-8 parts of Sn powder and 20-30 parts of silver-tin-mercury alloy powder AgSnHg. The novel mercury release agent with the high mercury release amount and the preparation method of the mercury release agent have the advantages that the preparation method is simple, the mercury release amount is high and the like. Plenty of screening experiments about components and use quantities are performed at the earlier stage. The results find that the novel mercury release agent has a remarkable releasing effect through reasonable matching and combination of all components. The mercury release amount of an original mercury release agent is increased, mercury can be sufficiently released, potential environment pollution caused by waste mercury release devices is reduced, and besides, the mercury content cannot exceed the standard.

Description

technical field [0001] The invention belongs to the technical field of mercury-releasing agents, in particular to a mercury-releasing agent with high mercury release and a preparation method thereof. Background technique [0002] Mercury agent, which introduces liquid mercury into the fluorescent lamp in the form of solid alloy, and the alloy releases mercury vapor to achieve the same effect as liquid mercury. Achieve green production and clean production. Commonly used amalgams include zinc amalgam, zinc-tin amalgam, and tin amalgam. [0003] In terms of accuracy: the accuracy of mercury content in existing conventional amalgams is controlled within ± (0.3-1.0mg), the accuracy of particle weight is controlled within ± (0.6-3mg), and the roundness of the sphere is controlled within 0.9 (the minimum diameter / maximum diameter of the sphere). Under the trend of advocating low-mercury and micro-mercury all over the world, lamp manufacturers will have higher and higher requirem...
