Be illustrated in figure 3 as the schema one of the preferable manufacture method specific implementation of the utility model energy-conserving plate material, be specially the method for making vacuum glass faceplate among the utility model embodiment one, comprise the steps:

Step 10, sealing thing 20 is arranged on the edge of glass substrate 10, and the middle part between layer glass substrate 10 disperses to lay, as shown in Figure 4, this sealing thing comprises sealing layer and zone of heating at least, wherein the sealing layer is two-layer, the wall of an every layer of sealing layer and a glass substrate is in abutting connection with setting, the non-crystalline type low melting glass that the sealing layer preferably adopts temperature of fusion to be lower than 600 ℃ is made, this zone of heating is arranged on the side of sealing layer away from glass substrate, be that one deck zone of heating is arranged between the two sealing layers, be provided with conductivity magnetic conductive material relatively preferably in the zone of heating, preferably adopt iron, nickel, iron-nickel alloy, metallic substance such as 426 alloys or kovar alloy are made zone of heating or are arranged on and form zone of heating in other material;

Step 20, apply alternating magnetic field on zone of heating, the magnetic conductive material that then has conductivity in the zone of heating produces the electric current heating under the effect of alternating magnetic field, the sealing layer is carried out heat fused;

In step 20, utilized the magnetic field induction electric current, claim the heating principle of eddy current again.Can under vacuum glass faceplate, place heating installation, be equiped with the electronic circuit board coil in the heating installation, produce alternating magnetic field, when containing conductivities such as iron, nickelalloy relatively the zone of heating of magnetic conductive material be in the alternating magnetic field preferably, magnetic line of force acts on zone of heating, zone of heating promptly begins to cut the alternation magnetic line of force and the electric current that produces alternation, and electric current overcomes when internal resistance is flowed has finished electric energy to heat energy conversion, makes the zone of heating evolution of heat heat the sealing layer.

Step 30, after the sealing layer is heated fusing, promptly weaken or stop to apply alternating magnetic field, sealing layer cooling after the fusing condensed, be connected with the wall of glass substrate, the sealing layer of zone of heating both sides with the glass substrate sealing-in of both sides, also is connected with zone of heating, therefore respectively simultaneously, two glass substrates are finally sealed, and form annular seal space because the sealing-in of edge makes between two glass substrates.

In technique scheme, adopt the heating principle of magnetic field induction electric current that the sealing layer has been carried out local heating, avoided heating that whole vacuum glass faceplate is carried out, glass substrate has only experienced once local moment and has not been higher than 600 ℃ pyroprocess in whole process, therefore can reduce to add the heat sealing process to greatest extent to the glass substrate Effect on Performance, avoid glass substrate to be removed tempering and degradation.And technique scheme can be finished heating by applying alternating magnetic field, and energy-conservation, safe, the reliable and environmental protection of its working process also can accurately realize by the control alternating magnetic field temperature controlling.

When at the above-mentioned energy-conserving plate material of antivacuum indoor manufacturing, through hole can be set on glass substrate, arranged outside sealing thing in the glass substrate through hole, comprise sealing layer and zone of heating, and the sealing layer is in abutting connection with the through hole setting, specifically can be around the outer surface that is laid in through hole, zone of heating is arranged on the side of sealing layer away from glass substrate, covers outside the sealing layer; Wherein, through hole is used for extracting air and is provided with on glass substrate, and operated by rotary motion is at the corner location place; The sealing thing is set at the through hole, and the sealing thing outside the through hole can be set after two glass substrates sealing-in form annular seal space again, also can be provided with by the sealing thing between glass substrate.Then after above-mentioned steps 30, carry out following step, as shown in Figure 5:

Step 31, when at least between the layer glass substrate behind the sealed formation annular seal space, vaccum-pumping equipment utilizes extraction pipe to pass through this through hole extracting air;

Step 32, when behind the environment that forms vacuum or near vacuum between the glass substrate or in can process at extracting air, on the zone of heating of through hole arranged outside, apply alternating magnetic field, the zone of heating in this through hole outside produces the electric current heating under the effect of alternating magnetic field, the sealing layer that the through hole is provided with heats;

Step 33, in the sealing layer of through hole is heated fusing and plate, reach required vacuum tightness after, weaken or stop to apply alternating magnetic field, push the zone of heating in the through hole outside, the sealing layer cooling after the fusing condensed the through hole sealing, and the zone of heating that is pressed forms the plane outside agglomerative sealing layer.

Technique scheme efficiently solves the problem of the most advanced and sophisticated rapid wear of existing vacuum-sealing mouth place formation.In the prior art, formed the tip at extraction pipe one end in the extraction pipe of sealed-off extracting air, this tip is the position of stress concentration, also is to be subject to extraneous collision and the position of damage.Prior art heats whole glass substrate and sealing material because of whole, thus be difficult to controllably carry out local heating in the through hole, to avoid most advanced and sophisticated appearance.Therefore, technique scheme is further handled the through hole of bleeding based on the principle of magnetic field induction electric current, forms the plane to overcome the problem of most advanced and sophisticated rapid wear, improves product work-ing life.Also can be used to form just as the zone of heating of heating source and to seal the plane, protect sealing effectively.

Can also further between the sealed glass substrate, getter be set, with the vacuum tightness of further raising glass substrate inside.

Technique scheme is applicable to sheet materials such as sealing-in low emissivity glass substrate, flame resistant glass substrate or reinforced glass substrate, also can extend further to other sheet materials of local heating sealing-in, for example, above-mentioned glass substrate can also be for ceramic substrate etc., as long as adopt corresponding sealing layer material.

In technique scheme, in manufacturing and use, keep high vacuum seal in order to guarantee energy-conserving plate material, need the coefficient of expansion of the thermal expansivity of zone of heating such as iron-nickel alloy and upper and lower base plate, low melting glass sealing layer to be complementary, thereby guarantee the good bonding performance of low melting glass material.On same energy-conserving plate material, the coefficient of expansion difference between general substrate, zone of heating and sealing layer material is not more than 20%, preferably is not more than 10%.For example, be (85 ± 10) * 10 when substrate uses thermal expansivity ^-7/ ℃ soda-lime glass, toughened glass or during ceramic substrate, can adopt " 426 " alloy as zone of heating, " 426 " alloy is a kind of alloys with controlled expansion, is also referred to as sealing alloy, its thermal expansion curve greatly about about 350 ℃ with the thermal expansion curve intersection of sodium calcium float glass.Therefore, near this temperature, use frit seal bonding, at room temperature do not have unrelieved stress.Because the specific technology sealing temperature of energy-conserving plate material generally is lower than 600 ℃, so the thermal expansivity of the low melting point glass material that requires and the thermal expansivity of glass substrate are complementary.Therefore preferably select the non-crystalline type low melting point glass material for use.Non-crystalline type low melting point glass material crystallization not in heating sealing by fusing process, the wetting property that therefore flows is good, and the heating for multiple times temperature of fusion is constant, forms good bonding and vacuum-sealing easily.Itself do not have tangible thermal expansivity to change before and after sealing by fusing, stress of sealing is fixed, and technology is fairly simple.

In making the process of vacuum glass faceplate, the thickness of glass substrate is big, when degree of the temper is high, and the placement position spacing of sealing thing can be bigger, the conduction heat when using to reduce.

The sealing thing that is used in the utility model energy-conserving plate material and the manufacture method thereof as shown in Figure 6, comprises one deck sealing layer 21 and one deck zone of heating 22 at least at least, and sealing layer 21 is established with zone of heating 22 is folded mutually.This sealing thing goes in the utility model energy-conserving plate material and the manufacture method thereof.The zone of heating material can be iron or nickel or iron-nickel alloy or 426 alloys or kovar alloy, and the sealing layer can be specially temperature of fusion less than 600 ℃ non-crystalline type low melting glass.

This sealing thing can independently be manufactured, and becomes a kind of solid components, adds in sealing-in to be placed into the position that substrate is treated sealing-in man-hour again.Relatively, prior art is coated on the glass substrate as the sealing thing after the glass powder with low melting point modulation can only being become slurry usually, as sealing-in frame or upholder, then fastens another piece glass substrate again, the reheat sealing-in, and can not be processed into the sealing-in frame or the upholder of solid form independently.Therefore, technique scheme is simpler than the prior art operation.

It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
