Abstract
The utility model relates to a low temperature plasma generating plate, composed of a ceramic substrate, a discharge electrode and a grounding electrode, wherein the discharge electrode and the grounding electrode are printed on the ceramic substrate by screen printing method and combined by sintering. The utility model has the advantages that the continuous service life of the low temperature plasma generating plate is more than 4000 hours, which is 4 to 8 times of the present products; because the discharge electrode and the grounding electrode are firm combined with the ceramic substrate, the disconnection of electrode is avoided in use; compared with the present products in equal specification, plasma yield per unit area is 4 times of the present products; because the utility model can be used in a relatively humid environment, the lifetime of a plasma generator is prolonged and the trouble rate is reduced.
Description
The utility model relates to plasma technique, and it is the low temperature plasma generation sheet of a kind of temperature＜150 ℃, is the critical component of plasma generator (machine).
Low temperature plasma generation sheet excites air to produce multiple plasma group under the effect of alternation high-frequency electric field, such as: antozone O, the HO of peroxide ion group
2, ozonide ion cluster O
3, hydrogen peroxide H
2O
2With hydroxyl ion group etc., these ion clusters all have very strong oxidation, decomposition, catalytic action to various bacteriums, virus, organic pollution etc., are widely used in health care, environmental treatment, water treatment and the three wastes and handle, and are emerging technologies in the world.
Plasma generation sheet in just using at present, its discharge electrode adopt simple metal material such as platinum, tungsten, aluminium, copper, titanium etc. more, and under the high-frequency electric field effect, these metal materials participate in discharge to be caused consuming, and the general life-span did not all reach 800 hours.The major defect of these products has at present: 1. lack useful life, useful life was less than 800 hours continuously; 2. under the high-frequency electric field incentive action, electrode easily comes off; 3. the plasma generation is few on the unit are; 4. cisco unity malfunction in a humid environment.
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, comprise that electrode easily comes off, useful life is short, on the unit are plasma generation few and in wet environment cisco unity malfunction or the like and provide a kind of long service life, electrode difficult drop-off, plasma generation amount big, have more the practical low form plasma generation sheet of easily promoting.
The purpose of this utility model is achieved in that it is made up of the solder joint 5 of solder joint 3, earth electrode 4 and the earth electrode of ceramic substrate 1, semi-conducting material discharge electrode 2, discharge electrode, discharge electrode 2 has adopted circle or oval large tracts of land discharge mode and discharge electrode 2 peripheral littler 2～3 millimeters than earth electrode, discharge electrode 2 is printed on the front of ceramic substrate 1, and earth electrode 4 is printed on the back side of ceramic substrate 1.
Through actual measurement, the utility model is compared with the product in just using at present, has following advantage: 1. sheet continuous useful life taking place greater than 4000 hours, is 4～8 times of product in just using; 2. the plasma generation amount is 4 times of product in just using; 3. electrode has adopted the high-temperature sintering process of semi-conducting material and electro-conductive glass, combines with ceramic substrate 1 firmly, does not produce the electrode obscission under the high-frequency electric field effect; 4. can normally use in greater than 85% damp attitude environment in relative humidity.

Fig. 2 is a cutaway view of the present utility model
Connection layout when Fig. 3 works for the utility model
Be described further below in conjunction with drawings and Examples.
Among the figure 1 be ceramic substrate, 2 for discharge electrode, 3 for the solder joint of discharge electrode, 4 for earth electrode, 5 for the solder joint of earth electrode, 6 for ac power input end, 7 for isolating transformer, 8 be that high-frequency converter is exported line for dc output end, 9 is high-frequency converter, 10 and 11.Ceramic substrate 1 selected introductions electric constant 〉=85, dielectrical loss coefficient 1 * 10

3Potsherd; Discharge electrode 2 adopts semi-conducting material and bonding agglomerated material.In the stencil printing mode electric slurry is printed on the front of ceramic substrate, solder joint 3 usefulness 63 of discharge electrode by required form
#The tin soldering forms, earth electrode 4 is the strong palladium-silver electrode of solderability, by required form electric slurry is printed on the back side of ceramic substrate in the stencil printing mode, after the preliminary drying and shaping, the ceramic substrate 1 of printing finish discharge electrode 2 and earth electrode 4 lain against in the continuous tunnel furnace under 850 ℃ of conditions, carry out sintering, discharge electrode 2 behind the high temperature sintering, earth electrode 4 has good bonding force with ceramic substrate 1, discharge electrode 2 forms the semi-conducting electrode based on the base metal tin ash after pyro-oxidation-reduction simultaneously, and the capacitance between discharge electrode 2 and the earth electrode 4 is between 20～35 micromicrofarads.At last, in the central authorities of discharge electrode 2 and earth electrode 4, be processed into the strong solder joint of solderability with the low temperature brazing method.Two solder joints 3 of sheet and 5 lead-out wire of burn-oning separately takes place, link to each other with the high-frequency converter output, the voltage that high-frequency converter is exported is: 3400V, frequency is 22KHz.Under the high energy electric field excitation, the edge generation corona discharge of discharge electrode 2, and the ionization ambient air produces plasma, because the utility model discharge electrode 2 adopts semi-conducting material, tool high anti-oxidation ability, discharge electrode 2 has adopted circular or oval large tracts of land discharge mode simultaneously, has not only strengthened discharge length, and increased machining area, obtained the advantage that electrode life is long, the plasma generation amount is big.
The utility model in use, mode by Fig. 3 connects, ac power input end 6 is connected the 220V civil power, through isolating transformer 7 output LOW voltage supply high frequency converters 9, the high tension voltage of high-frequency converter 9 output voltage 3400V frequency 22KHz 10 and 11 is taking place energy on the sheet by going between, and sheet takes place under the high-frequency electric field excitation, semi-conducting material discharge electrode 2 edges produce corona discharge, and ionization surrounding air also produces multiple plasma.
