Description
Technical field
The present invention relates to a kind of vacuum heat-insulating plate with the manufacturing of composite getter, can be applied in and absorb gas in the vacuum heat-insulating plate, keep vacuum.
Background technology
Along with growth in the living standard, people are more and more to the demand of freezing insulation.Use at low temperature storage transportation and refrigeration household appliances industry inside thermal conservation material is more and more extensive.Simultaneously along with energy crisis, energy-conservationly become a worldwide problem.Vaccum thermal insulation technique is a kind of very efficiently insulation method.Its primary structure is a vacuum heat-insulating plate (Vacuum Insulation, Panel, be called for short VIP), this plate outer surface is adiabatic film, there are core and drier and getter in inside, and inside is vacuum state, like this so that the factor of gas molecule heat conduction be eliminated, thereby make adiabatic effect be much better than other heat-insulating materials, its heat transfer efficiency is 1/3 to 1/10 of conventional insulation material.External VIP technology has developed for many years, and we still are in the stage at the early-stage at this domestic technology.
By adiabatic principle as seen, the vacuum in the VIP plate is adiabatic key factor.The principal element that affects vacuum is the continuous infiltration of gas in the use procedure, and the continuous release gas of internal material, all can cause the decline of vacuum.Therefore, the use of drier and getter becomes extremely important.
In present VIP production technology, the VIP plate is finished product after the vacuum sealer encapsulation and dispatches from the factory.Along with passage of time, constantly have gas molecule to infiltrate inner, and the air release in the internal material is out, vacuum descends gradually, makes VIP plate thermal conductivity factor rise the final products life termination.If therefore in the plate getter is housed, in the future greatly prolonged in the VIP life-span.
Present getter is mainly the product of import, and its main material composition is that becket inside is filled to the barium lithium alloy, and barium lithium alloy outside is drier.And no matter present domestic getter is evaporable barium aluminium getter or non-evaporable zirconium class getter, and a common feature is arranged, need to be in being installed to user's device after, activated at.Temperature reaches more than 400 degree usually, and is high even surpass 1000 degree, because the material of VIP plate, this temperature is impossible realize in the production process of VIP plate.
And the barium lithium alloy is a kind of activated degasser of exempting from, and need not activated at, in the VIP plate of only need packing into, can reach inspiratory effects.Barium lithium getter mainly absorbs nitrogen, oxygen, carbon dioxide.But, using the getter that contains the barium lithium material, it can reaction produce hydrogen after meeting water, and the possibility of burning is arranged.This product just once appearred using in Japan, the breaking out of fire in removal process of waste product wherein, and this safety and environment bring the accident of harm.
And zeolite is widely used industrial.Mainly be because this class mineral crystal has and opens very much spacious silica screen work, form uniform duct, many apertures and the very large hole of inner surface at crystals, thereby have unique performances such as absorption, screening, ion-exchange and catalysis.Why zeolite can adsorb other materials in a large number, mainly is to be determined by his internal structure of uniqueness.After the water in the zeolite screen work is removed, form the very large hole of internal surface area, can store a large amount of molecules.Zeolite can be strong adsorbed water, methyl alcohol, ethanol and can not adsorb ethane, acetone and benzene fully, namely have the characteristic of selective absorption.
Silica gel, activated alumina and active carbon all do not have fixing uniform pore size, pore diameter range alters a great deal, pore size such as silica gel does not wait from 10～1000A, the aperture of activated alumina is between 10～10000A, therefore sized molecules all can enter the duct and is adsorbed, therefore do not have sieve performance, namely do not have selectivity.Zeolite has high efficiency of additive capability, particularly the senior property molecules such as H2O, NH3, H2S, CO2 is had very high affinity.Especially to water, even under the unfavorable conditions such as low relative humidity and low concentration, high temperature, still can adsorb.Zeolite has high efficiency of additive capability, particularly the senior property molecules such as H2O, NH3, H2S, CO2 is had very high affinity.Especially to water, even under the unfavorable conditions such as low relative humidity and low concentration, high temperature, still can adsorb.
Summary of the invention
Getter of the present invention; using on the zeolite base just; increase other drier that use domestic maturation; and produce in a vacuum; this getter behind the Kaifeng is (in 10 minutes, this time is sealed off getter to putting required maximum duration in the VIP plate when being the production of VIP plate) in of short duration exposure air; owing to stopping of desiccant layer, can protect zeolite not contact with air molecule.
Vacuum heat-insulating plate composite getter of the present invention comprises zeolite layer and desiccant layer, and zeolite places the inside of desiccant layer.The desiccant layer that has wrapped up getter can also be placed in the metallic carrier that does not seal.As long as have at least a suction face to expose.
Another kind of scheme is, described vacuum heat-insulating plate comprises zeolite layer, a metallic carrier and desiccant layer with composite getter, and desiccant layer is encapsulated in zeolite layer in the metallic carrier.Compressing in a vacuum, vacuum storage or encapsulation also can be that inert gas stores or encapsulation.
Described drier is selected from silica gel, calcium oxide, alkaline earth oxide, metal oxide, sulfate, chloride and bromide drying material or mixture wherein.
Vacuum heat-insulating plate composite getter of the present invention, its mesolite can absorb the gases such as nitrogen, carbon dioxide, organic gas, and drier can the adsorbed water steam.
Vacuum heat-insulating plate of the present invention with the preparation process of composite getter is:
1) with degassed in the zeolite powder vacuum heat treatment furnace;
2) in the vacuum argon filling glove box that zeolite is compressing, again with reshaping (Fig. 1) behind the drier 2 parcel getters;
Or in carrier 3, will in the vacuum argon filling glove box, put into by compressing zeolite powder 1, recharge again compacting (Fig. 2) behind the drier 2; Or in the vacuum argon filling glove box, the zeolite powder 1 of packing into first in carrier 3 reinstalls drier 2 rear compressing (Fig. 3).
3) composite getter vacuum storage or the vacuum packaging after the compacting also can be to store under inert gas or packing.
Another kind method is, first according to above-mentioned steps 2) after the method moulding, again product is placed vacuum heat treatment degassed.And then vacuum storage or vacuum packaging.
