Abstract

The invention discloses a low-temperature amalgam and relates to an amalgam material applicable to energy saving lamps and fluorescent lamps. The low-temperature amalgam comprises the following components in percentage by mass: 1%-20% of Bi, 0.5%-5.0% of Zn, 40%-78.5% of Sn and 10%-55% of Hg. Zn is capable of increasing hardness of the amalgam and enabling the amalgam to be not easily adhesive at normal temperature; Bi is capable of increasing brittleness of the amalgam, enabling the amalgam to be easily formed, and improving the yield and production efficiency. The amalgam is solid at normal temperature and capable of precisely controlling mercury consumption of each lamp tube, and the mercury is unlikely to lose, so that the pollution to the environment is avoided. The amalgam is capable of directly replacing liquid mercury and applicable to energy saving lamps and fluorescent lamps; the working temperatures of lamp tubes manufactured by the amalgam are 40-50 DEG C, and the low-temperature starting performance is good; the amalgam with high content of mercury is applicable to straight-tube fluorescent lamps with low working temperatures according to difference of components and content of the low-temperature amalgam; the amalgam with low content of mercury is applicable to bare-spot energy saving lamps with high working temperatures.

Description

Low temp amalgam

Technical field

The present invention relates to a kind of amalgam material for electricity-saving lamp, fluorescent lamp etc., especially relate to a kind of Low temp amalgam.

Background technology

In the production field of electricity-saving lamp, fluorescent lamp, high-temperature amalgam during the electricity-saving lamp of lamp works temperature higher (being greater than 60 ℃) all adopts, the electricity-saving lamp of the bare spots such as the straight tube fluorescent lamp of working temperature lower (40～50 ℃), U-shaped, spiral still adopts liquid mercury, the remarkable defect of liquid mercury is easy loss, easily contaminated environment, and the mercury use of every tubes can not accurately be controlled.

Chinese patent CN102324378A discloses a kind of Novel low-temperature amalgam, and this Novel low-temperature amalgam comprises kernel, in the surface coverage of kernel, has mercury zinc alloy surface layer.Compared with existing Low temp amalgam, the outstanding advantages of this Novel low-temperature amalgam is, because its mercury atom mean allocation is in zinc amalgam surface layer part, the rate of release of mercury atom in fluorescent tube, obviously fast than the rate of release of traditional Low temp amalgam mercury atom, its fluorescent tube time-to-climb short, effectively reduced the mercury use of fluorescent lamp tube simultaneously, reduce mercury pollution, there is good practicality, can produce good economic benefit and social benefit.

Chinese patent CN1725433 discloses a kind of Low temp amalgam, and the weight percentage of each component is Ag0.5%～5.0%, Cu0%～2.0%, Sn40%～79.5%, Hg20%～53%.The Low temp amalgam of this invention, be at normal temperatures solid-state, the fluorescent tube of making all can have good cold-starting characteristic, and directly instead of pure mercury, in fluorescent lamp, electricity-saving lamp, can provide the mercury vapour that approaches pure mercury to press, under this amalgam normal temperature, become solid, be difficult for running off, can prevent the pollution of mercury to environment, and be convenient to weigh, can accurately control the pure mercury amount of fluorescent tube.The amalgam that mercury content is less, is applicable to the bare spot electricity-saving lamp that working temperature is higher, as is applied to ring lamp, 2D lamp, 2U, screw lamp etc.; The amalgam that mercury content is more, is applicable to the straight tube fluorescent lamp that working temperature is lower, as application T8, T5, T4 etc.

Summary of the invention

The object of this invention is to provide the mercury use that can accurately control every tubes, can provide at normal temperatures the mercury vapour that approaches liquid mercury to press, make fluorescent tube have a kind of Low temp amalgam of good low temperature startability.

Each component of described Low temp amalgam by mass percentage content is Bi1%～20%, Zn0.5%～5.0%, Sn40%～78.5%, Hg10%～55%.

The preparation method of described Low temp amalgam is identical with the preparation method of existing middle high-temperature amalgam.

Compared with existing Low temp amalgam, the composition Zn in Low temp amalgam of the present invention can increase amalgam hardness, makes to be difficult for adhesion under its normal temperature, and composition Bi can increase the brittleness of amalgam, and it is more easily shaped, and improves rate of finished products, enhances productivity; Under this amalgam normal temperature, be solid-state, can accurately control the mercury use of every tubes, and the difficult loss of mercury, can be to environment.

Low temp amalgam of the present invention is replacement liquid mercury directly, and in electricity-saving lamp, fluorescent lamp, the working temperature of the fluorescent tube of making is 40～50 ℃, has good low-temperature startup performance.

The amalgam different with content according to Low temp amalgam constituent, mercury content is higher, is applicable to the straight tube fluorescent lamp that working temperature is lower, as is applied to T4, T5 type etc.; The amalgam that mercury content is lower, is applicable to the bare spot electricity-saving lamp that working temperature is higher, as is applied to screw lamp, 2U lamp etc.

Embodiment

The present invention is further illustrated for following examples.

Embodiment 1

Each component of described Low temp amalgam by mass percentage content is Bi3%, Zn2%, Sn40%, Hg55%, and this amalgam characteristic approaches liquid mercury, for direct replacement liquid mercury.

Embodiment 2

Each component of described Low temp amalgam by mass percentage content is Bi1%, Zn2%, Sn56%, Hg41%, is applicable to the straight tube fluorescent lamp that working temperature is lower, as T4, T5 etc.

Embodiment 3

Each component of described Low temp amalgam by mass percentage content is Bi20%, Zn5%, Sn45%, Hg30%, is applicable to the bare spot electricity-saving lamp that working temperature is higher, as screw lamp, 2U lamp etc.

Embodiment 4

Each component of described Low temp amalgam by mass percentage content is Bi10%, Zn1%, Sn69%, Hg20%, can be used on bare spot electricity-saving lamp.

Embodiment 5

Each component of described Low temp amalgam by mass percentage content is Bi11%, Zn0.5%, Sn78.5%, Hg10%, can be used on bare spot electricity-saving lamp.

In the various embodiments described above, amalgam is along with mercury content raises, and its working temperature reduces, and general work temperature, between 40～50 ℃, all has good low-temperature startup performance.

The relevant test data of fluorescent tube that adopts Low temp amalgam of the present invention to prepare is referring to table 1.

From the test data of table 1, can find out, the sharpest edges of Low temp amalgam of the present invention are that the rate of climb is fast, luminous flux is high, and the logical interior light of 40.11%, 60s that just can reach of 2s light leads to 96.65%.

Claims
