Abstract

The invention relates to a novel mercury releasing agent and a preparing method thereof. The novel mercury releasing agent comprises, by weight, 50-95 parts of titanium-mercury alloys Ti3Hg, 20-60 parts of zirconium-aluminum alloys ZrAl, 5-15 parts of high-purity titanium powder Ti, 5-12 parts of stannum powder Sn and 20-30 parts of silver powder Ag. The novel mercury releasing agent and the preparing method thereof have the beneficial effects that the preparing method is simple and the pollution degree is low. An inventor carries out a large number of component and dosage screening experiments and unexpectedly finds that an obvious releasing effect is achieved through reasonable matching and the combination of the components in the technical scheme. The mercury releasing amount of an original mercury releasing agent is increased, mercury can be sufficiently released, potential environment pollution caused by abandoned mercury releasing devices is reduced, and meanwhile it can also beensured that the mercury content cannot exceed the standard.

Description

technical field [0001] The invention belongs to the technical field of mercury-releasing agents, and in particular relates to a novel mercury-releasing agent 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 requirements on ...
