Abstract
The present invention discloses a leadless amalgam which belongs to the technical field of amalgams. The present invention comprises the following components with quality contents: 30 percent to 70 peThe invention relates to a leadless amalgam, belonging to the amalgam technique, which comprises following components in mass proportions: Bi in 30-70%, Sn in 10-50%, Hg in 3-12%, and In in 0-20%. Thercent of Bi, 10 percent to 50 percent of Sn, 3 percent to 12 percent of Hg, and 0 percent to 20 percent of In. The amalgam of the present invention can be obtained by a preparation method of a general invention can uses general alloy amalgam preparation method to attain said amalgam. The inventive amalgam can attain the Hg pressure and temperature character curves similar to the M, N, A, and B to alloy amalgam. By adopting the amalgam of the present invention, performance curves of the atmospheric pressure of mercury and temperatures, which are equal to or similar with the performance curves replace the M, N, A, and B. And the inventive mercury has high strength, and high melting point. The inventive amalgam has strong resistance to oxidation, which can be exposed in air for long time. Anof M, N, a, B can be obtained, and the performance curves can be replaced with the amalgams containing Pb, such as the M, the N, the A, the B, etc. The present invention has the other advantages of bid since there is no lead in the amalgam, it can avoid polluting the environment. The invention can be used in the 2U, 3U, screw and 2D energy saving lamps, ultraviolet disinfection lamp and high-frequg strength of a mercury ball, and high melting point of the mercury ball. The present invention is especially suitable for making lamps of round exhausts for companies to make the lamps; in addition, ency non-electrode lamp. the present invention has strong inoxidability of the amalgam, can be exposed in air for long time, and the phenomenon of oxidation stain can not occur; because the amalgam does not contain lead, the phenomenon of lead pollution can not occur. The present invention can be used for energy saving lamps, such as 2U lamps, 3U lamps, spiral lamps, 2D lamps, etc., ultraviolet germicidal lamps, high-frequency non-electrode lamps, etc.
Description
Technical field
The present invention relates to a kind of amalgam material that is used to make fluorescent lamp, electricity-saving lamp.
Background technology
In fluorescent lamp, electricity-saving lamp, be extensive use of at present the amalgam material is arranged, shown in M, the N of the characteristic curve that its mercury vapour is pressed PH and temperature T in as shown in drawings, A, the B, the component of this amalgam is Bi, Pb, Sn, Hg, mercury content corresponds to 3%, 5.4%, 6%, 12% respectively, wherein the content of Pb has between 18%-28%, but Pb is a harmful element, pollutes the environment.
Summary of the invention
The purpose of this invention is to provide a kind of leadless amalgam, in the amalgam material, do not use harmful lead, simultaneously, can acquisition and identical or akin characteristic curves such as M, N, A, B.
For achieving the above object, the invention provides a kind of leadless amalgam, it is made up of the following component of mass content: Bi 30～70%, Sn 10～50%, Hg 3～12%, In 0～17%.
Adopt the preparation method of conventional alloy amalgam can obtain leadless amalgam of the present invention, difference on the preparation method is that the raw material of its use is different, adopt amalgam of the present invention, can press and temperature characteristics by the identical or akin mercury vapour with M, N, A, B etc. of acquisition, alternative characteristic curve is the amalgam that M, N, A, B etc. contain Pb; Another advantage of this patent amalgam is that the intensity of mercury ball is big, the fusing point height, and the round exhaust machine system lamp that is particularly suitable for making lamp enterprise is used; In addition, amalgam non-oxidizability of the present invention is strong, can long term exposure in air, can oxidation stain; Owing to do not have lead in the amalgam, therefore lead contamination can not occur.The present invention can be applicable to electricity-saving lamps such as 2U, 3U, spiral, 2D, ultraviolet germicidal lamp and HF lamp without electrodes etc., and the various lamps of producing according to the present invention meet European Union's " about banning use of some harmful substance in the electronic equipment " requirement of (being called for short the ROHS instruction).
