Description
Technical field
The present invention relates to a kind of vacuum suction device, especially keep a kind of suction means that is used for vacuum insulation panel of degree of vacuum in the thermal baffle vacuum jacket.
Background technique
Because vacuum insulation panel has good insulation and environmental-protecting performance, progressively is widely used in field of thermal insulation such as oil, chemical industry, building, refrigerators.But vacuum insulation panel tends to along with the prolongation of time degree of vacuum be descended, and directly has influence on the thermal insulation property of vacuum insulation panel, traces it to its cause, and mainly is residual CO, CO in the chuck
2, O

2, but the rate of adsorption is relatively low, and the ability of adsorb organic compound gas is very limited.
Gondola SAES Getters S.p.A. proposed name to Patent Office of the People's Republic of China again on August 6th, 1996 and has been called " combination layer of getter material and charging appliance thereof " application for a patent for invention, its patent No. is: ZL96109371.4, this patent disclosure the mixture of Metal Palladium of oxide M O and≤2% (weight) of the transition metal selected in the oxide of a kind of oxide, copper or their mixture with cobalt be H under getter material and the room temperature
2The O vapor pressure is lower than the absorbent material of 1 handkerchief, and the suction device of being made up of them, and wherein absorbent material contacts with external environment condition.Compare in the ZL95193987.4 of first to file patent with the said firm, though improved CO, CO
2And H
2Adsorptive power, and can adsorb organic compound gas, become closely undue in order to prevent absorbent material between the powder because of the absorption of moisture makes, cause gas to pass through difficulty, add alumina powder in the absorbent material, because aluminium oxide belongs to inert material, its effect in absorbent material is single.Because absorbent material is exposed in the air all the time, in the technological preparation time, getter material just is in air-breathing working state, has consumed gettering ability, and effective gettering ability of charging appliance is descended.
Summary of the invention
The objective of the invention is to: at the suction means of present maintenance vacuum insulation panel degree of vacuum, especially China Patent No. is that the rate of adsorption that exists of ZL95193987.4 is relatively low, and the ability of adsorb organic compound gas is very limited, and the aluminium oxide in the ZL96109371.4 absorbent material belongs to inert material, its effect in absorbent material is single, practical problem in that the internal cause absorbent material exposure of technological preparation time descends effective gettering ability of charging appliance provides a kind of suction means that is used for vacuum insulation panel.
The object of the present invention is achieved like this: a kind of suction means that is used for vacuum insulation panel, comprise carrier, absorbent material, separating materials and getter alloy, it is characterized in that: also comprise organic gas-absorbing layer and anti-expanding material, mix the back by absorbent material and anti-expanding material and form air-permeable layer, getter alloy, organic gas absorbed layer and air-permeable layer layering successively place carrier from inside to outside, wherein, the interlayer of getter alloy and organic gas absorbed layer is provided with separating materials.
Described carrier is the cylindrical staving that adopts metal or plastic production, and its diameter is 10～80mm and open-top; To top layering setting successively, the air-permeable layer outside is for being located at the protective film of carrier top bead by the bottom of carrier for described getter alloy, organic gas absorbed layer and air-permeable layer.
The perforate simultaneously of the bottom of described carrier; Described getter alloy places the middle part of carrier, and organic gas absorbed layer, air-permeable layer are provided with to the top and the bottom layering of carrier successively, places the air-permeable layer outside of carrier upper and lower end to be respectively the protective film that is located at carrier top or bottom bead.
Described organic gas absorbed layer is the strong oxidizer absorbed layer; Absorbent material in the air-permeable layer and anti-expanding material proportions of ingredients are 1～150: 1; Described getter alloy is the barium lithium alloy, or the barium sodium alloy, and their powder compaction is become the porous muffin; Described separating materials is a screen cloth, or mesh grid, or filter paper.
Described strong oxidizer comprises: potash bichromate, or sodium dichromate, or natrium nitrosum, or cobalt oxide, and their powder compaction become the porous muffin; Absorbent material comprises in the air-permeable layer: magron, or U-Ramin MC, or calcium oxide, or phosphorous oxide; Anti-expanding material comprises in the air-permeable layer: molecular sieve, or zeolite, or active carbon, or silica; After mixing in proportion, the powder of absorbent material and anti-expanding material is pressed into the porous muffin.
The invention has the advantages that: because the open-top of carrier, or the perforate simultaneously of open-top bottom, make its working surface that bigger exposed surface area be arranged, the rate of adsorption improves relatively; The organic gas absorbed layer of setting up has improved the adsorptive power to the organic gas that may form in the vacuum insulation panel; Mix in the absorbent material such as molecular sieve, or zeolite, or active carbon, or the anti-expanding material of silica and so on forms air-permeable layer, these anti-expanding materials not only can utilize the porous breathable performance of himself, and the restriction absorbent material expands and keeps gas to pass through, and guarantee that strong oxidizer absorbed layer and getter material absorb the validity of gas, and gas also had certain adsorptive power, improved gettering efficiency greatly.
