The making step of little mercury technology:
1, the making of amalgam:
1. select materials:
Calcium 5-43 kilogram, calcium are a kind of chemical elements, chemical symbol Ca; Bismuth 35-55 kilogram, bismuth belong to VA family metallic element, symbol of element B
1Silver 7-13 kilogram, silver belongs to VA family metallic element, symbol of element Ag; Zinc 6-13 kilogram, zinc belong to IIB family metallic element symbol, symbol of element Zn; Tin 7-14 kilogram, tin belong to IVA family metallic element, symbol of element Sn, mercury 2-5 milligram.
2. preparation:
Get by weight calcium 5-43 kilogram, bismuth 35-55 gram, silver-colored 7-13 gram, zinc 6-13 gram, tin 7-14 gram adds mercury 2-5 milligram and is mixed and made into the solid granulates Φ 0.5mm-1mm amalgam that the mercury content weight ratio is 2%-5%, can directly come into operation, the amalgam of production needs bottled refrigerator low-temp storage.
2, the manufacture method of little mercury lamp:
During making, taking out bottled amalgam from refrigerator put at room temperature 2 hours, open bottle cap, the amalgam particle that will the contain mercury element external diameter of packing into is in the special glass tube that arranges of the bulb bottom of 4.75mm, this glass tube is connected with the bulb housing vacuum chamber that inwall evenly scribbles the fluorescence powder, then with welding gun the glass mouth of pipe is shut, open molecular pump and carry out vacuumizing and exhausting, until vacuum degree is when reaching 2.0E-2, have or not gas leakage with the vacuum detection instrument inspection again, during without gas leakage bulb is carried out applying argon gas 20P, then with the liquefied gas welding gun bulb is sliced off in frame, bake mercury aging.During roasting mercury, when the temperature of roasting mercury machine reaches 280 when spending, again bulb is placed on the roasting mercury machine, treats that the roasting mercury machine roasting mercury that rotates a circle finishes, take out bulb and be placed on the agingtable aging 1 hour and make little mercury Non-polarized lamp.Power-on when lighting starts coupler, sends mercury atom after solid-state amalgam is excited, and mercury atom excitation fluorescence powder is luminous.When powered-down, mercury atom reverts to again solid-state amalgam, is attracted to indium online.When Non-polarized lamp damages or discards, will consolidate amalgam and reclaim from indium is online, avoided the pollution of mercury to environment.The use of indium net is to be increased to 5 * 7mm on the basis of original surface area 5 * 5mm, can directly come into operation.Described indium net also claims Auxiliary amalgam, is to make dictyosome by sheet metal punching or wire netting, at its surface-coated indium layer, therefore claim the indium net.The indium net is installed in the top of bulb inner tube, and described inner tube is to be provided with an inwards inner tube of projection in the bottom of bulb, scribbles fluorescent material in the cavity of inner tube, and coupler places in the cavity, and the space between bulb and the cavity is vacuum.The purposes of indium net is to guarantee that fluorescent tube reaches the parts of definite value fast in startup moment mercury vapour pressure, can absorb quickly the auxiliary heat energy of penetrating of heat, making indium net sheet is to be warming up to more than 300 ℃ auxiliary amalgam moment, the faster mercury atom that discharges in a larger amount, help fluorescent tube to start fast, shorten luminous flux settling time, simultaneously lamp tube starting stable after the temperature of indium net sheet lower, indium layer wriggling avoided in the location that more is conducive to the indium layer.The operation principle of indium net is: absorb mercury atom during light-off, emit mercury atom when fluorescent tube starts.Therefore, to being the requirement of indium net: 1, the surface has the indium coating can inhale, put mercury atom.2, base material has good spot welding characteristics.3, effective surface area, namely the area of coated indium layer wants large.4, thermal capacity is little.The structure of indium net all is hole or the annular knurl that shuts out rhombus at stainless steel band at present, is coated with the indium layer again, can prevent that like this indium runs off, and reduces thermal capacity.
Non-polarized lamp is mercury---the inert gas low-pressure discharge lamp; mercury vapour is pressed its discharging efficiency is played conclusive effect; select qualified amalgam; can be with the mercury vapour pressure-controlled at optimum range; thereby improve the photoelectric properties such as luminous efficiency of Non-polarized lamp; pass through simultaneously the use of amalgam with the consumption of effective control mercury, reduce and pollute, reach the purpose of protection of the environment.
Amalgam is mercurous alloy, and mercury content is solid-state when few, for lamp processed area and consumption area good environment protecting is arranged all.In lamp link processed, because the mercury atom volatile quantity of amalgam is far smaller than liquid mercury, can effectively overcome the harm that liquid mercury runs off, effectively protect the production environment in lamp processed area because of specific energy.At consumptive link, amalgam can critically be controlled the mercury use of Non-polarized lamp, can easily meet RoHS Directive (using some harmful substance instruction about restriction in electronic electric equipment), solid-state amalgam is conducive to the recycling of discarded Non-polarized lamp simultaneously, easily implements European Union directive on WEEE " about electrical equipment and the instruction of electronic equipment waste material ".
Non-polarized lamp belongs to the low pressure fluorescent lamp, and it is 0.8Pa that its best mercury vapour is pressed.As being 40-50 ℃ with its corresponding lamp tube wall temperature of liquid mercury, tube wall temperature is whenever above 1 ℃, its light efficiency namely reduces approximately 1%, easily form " temperature rise light decay ", the lamp tube wall temperature of Non-polarized lamp mostly surpasses more than 50 ℃, that have even up to more than 150 ℃, affect approximately 20%-30% of its luminous efficiency, serious can reach more than 50%, amalgam then can obtain different temperature characteristicss by regulating the proportioning of mercury and alloying element, and different amalgam is under different temperature, can obtain more metastable mercury vapour and press 0.8Pa, therefore a large amount of test data by for many years proves, as long as Non-polarized lamp is selected qualified amalgam, can make fluorescent tube remain best luminous efficiency, overcome " temperature rise light decay " that liquid mercury forms, reduce simultaneously mercury use.
3, amalgam has 40% energy-saving effect than liquid mercury in Non-polarized lamp:
Non-polarized lamp and low pressure fluorescent lamp only have mercury vapour to be pressed in 0.8Pa, could obtain best light efficiency, when its principle of luminosity depends on the mercury atom that is stimulated and revert to ground state, the 253.7nm ultraviolet ray that discharges, the ultraviolet intensity of 253.7nm has determined the performance of various fluorescent tubes, the 253.7nm ultraviolet ray is stronger, the luminous efficiency of excitated fluorescent powder is higher, therefore, in the manufacturing and designing of various Non-polarized lamps, final purpose all is to obtain the strongest 253.7nm ultraviolet ray altogether.
(1) ultraviolet ray or claim ultra-violet radiation results near the arc axis of positive column, runs on the lamp tube wall excitated fluorescent powder through many times bump luminous.Ultraviolet ray is subject to mercury atom bump on every side in running to the process of lamp tube wall, having portion of energy to incur loss is absorbed by mercury atom on every side, be called again resonance absorption, therefore the real luminous uitraviolet intensity of excitated fluorescent powder is that ultraviolet radiation deducts remaining effective ultraviolet radiation after the resonance absorption, be that ultra-violet radiation subtracts resonance absorption and equals effective ultra-violet radiation, therefore the mercury atom concentration (mercury vapour pressure) in the fluorescent tube can not too low (unfavorable generation ultra-violet radiation), can not too high (being unfavorable for resonance absorption).
Facts have proved: only have when mercury atom concentration (mercury vapour pressure) is near 0.8Pa, could obtain the strongest effective ultra-violet radiation.
(2) formation of temperature rise light decay, mercury vapour in the electrodeless fluorescent presses (mercury atom concentration) to be directly proportional with the lamp tube wall temperature, when lamp tube wall temperature during 40 ℃ of left and right sides, the mercury vapour that can obtain 0.8Pa in the pipe is pressed, traditional T12 fluorescent lamp is burning-point under 25 ℃ of room temperatures, its lamp tube wall temperature approximately is 40 ℃, the mercury vapour that can obtain 0.8Pa is pressed, luminous efficiency is also best, but along with fluorescent tube directly attenuates and the rise of compact fluorescent lamp, the temperature of lamp tube wall is higher than 40 ℃ far away, and the mercury vapour in the fluorescent tube is pressed also far above 0.8Pa, temperature is higher, it is larger that the mercury vapour pressure departs from 0.8Pa, and resonance absorption is stronger, and the effective ultraviolet radiation of 253.7nm is lower, the luminous efficiency of fluorescent tube also reduces, and the phenomenon that the luminous efficiency of this fluorescent tube descends along with the rising of lamp tube wall temperature is called the temperature rise light decay.
The temperature rise light decay is reversible, and after lamp hole temperature reduced, light efficiency can recover, and practice shows, after lamp hole temperature is higher than best tube wall temperature, whenever departs from 1 ℃, will affect the light efficiency of 0.8%-1%.For example: the lamp hole temperature of certain Globular energy saving lamp reaches 80 ℃, and is above, and its light efficiency loss will be above 30%.
(3) select amalgam can overcome the temperature rise light decay, make fluorescent tube remain high-luminous-efficiency.The temperature rise light decay that brings in order to overcome liquid mercury, the minority cast can be designed to " cold junction ", obtains the part effect, also must select the amalgam that is suitable for lamp hole temperature but really will solve temperature rise light decay problem.
Described composite molecular pump is the tandem compound of turbomolecular pump and molecular drag pump, integrates the advantage of two kinds of pumps.(10-6～1Pa) have larger pumping speed and higher compression ratio has improved delivery side of pump pressure to pump greatly in very wide pressure limit.A kind of composite molecular pump that adopts aerostatic bearing and movable sealing that France Alcatle company produces can have been accomplished oil-free, and without directly exhaust in the atmosphere of fore pump.
The classification of composite molecular pump: the form of composite molecular pump is a lot, divides by structure, mainly contains two kinds: a kind of is the tandem compound of turbo blade and disc type traction pump; Another kind is the tandem compound of turbo blade and cartridge type traction pump.Turbine stage is mainly used to improve the pumping speed of pump, the general blade shape that is conducive to improve pumping speed that adopts, and progression is in the l0 level.Draft stage is mainly used to increase the compression ratio of pump, improves delivery side of pump pressure.The disc type draft stage is to leave according to certain rules several molded line grooves on dull and stereotyped disk plane, then the several piece disk is connected in series formation, and molded line has Archimedes spiral, logatithmic spiral, circular arc line etc.Disk by high speed rotating when bleeding carries out " dragging " to gas molecule, makes it reach from inside to outside the directed flow of back and forth turning back of ecto-entad along groove, thereby reaches the purpose of bleeding.The cartridge type draft stage is to open the groove of certain section configuration on the face of cylinder of columnar rotor or stator, such as the multi-head spiral groove of rectangle, circular arc, triangle and other shape.Because skeleton symbol traction pump molded line groove is opened on rotor cylindrical outer surface or pump housing inner surface, therefore can take full advantage of the higher linear velocity of cylinder cylindrical carries out momentum transfer to gas molecule, improves the effect of bleeding of pump.In manufacturing and designing, can reach the comparatively ideal effect of bleeding by the angle (lead angle) that changes the spiral grooves passage and bleed between the direction.
