Abstract
The invention discloses vacuum glass and a vacuum glass production method. The method specifically comprises the steps of: activating getters in a vacuum chamber at a set vacuum degree to enable a gas absorbing film evapotranspired by the getters to be attached onto the internal surface of glass to be laminated, and then conducting subsequent glass lamination. The activation treatment of the getters is conducted in the vacuum chamber before the vacuum glass is formed, one gas absorbing film is attached onto the surface of the glass which is treated after the getters are activated and then the glass lamination is conducted. Since the gas absorbing film exists on the internal surface of the glass, the vacuum glass produced by using the method reaches the goals of absorbing gas molecules and keeping the vacuum degree of the vacuum glass. Besides, since the getters are not placed in the vacuum glass, grooves are not required to be dug on the glass, the production processes are reduced, the production cost is reduced, and the produced vacuum glass is more attractive.
Description
Technical field
The present invention relates to a kind of method of manufacture of vacuum glass and the vacuum glass for preparing through this method.
Background technology
The vacuum tightness of vacuum glass is a significant parameter that influences the vacuum glass quality; Because the structure formation of various sealing-ins all outwardness leakage; Thereby after causing the vacuum glass life-time service; Its inner vacuum tightness can descend gradually, is provided with the getter that is used to absorb atmospheric molecule in the vacuum glass for this reason, to keep necessary vacuum tightness in the vacuum glass.
Getter can be divided into two types of evaporable and non-evaporables, and evaporable air-absorbing agent need carry out heat activation to air-breathing metal to be made evaporation of metal come out to be adsorbed onto to form getter film on the chamber walls, and this kind getter is a material of main part with barium, strontium, magnesium, calcium.Nonevaporable getter need not evapotranspire air-breathing metal out, but makes it have gettering ability through air-breathing metallic surface is activated, and often is the main body with zirconium, vanadium at present.
The very for a short time 0.1-0.2mm that is generally in gap in the vacuum glass between two sheet glass, above-mentioned any getter of the not enough placement in this gap, conventional method is at the getter groove that is provided with on glass, like Chinese patent 201020586849.9.Though can keep the vacuum tightness in the vacuum glass through getter like this, the getter that is placed in the vacuum glass can influence the attractive in appearance of glass, but also need put the getter groove on glass digging, and has improved the production cost of vacuum glass.
Summary of the invention
Problem to prior art exists the object of the present invention is to provide a kind of production cost low, does not influence vacuum glass method of manufacture and the vacuum glass of producing through this method of the aesthetics of glass.
For realizing above-mentioned purpose; Vacuum glass method of manufacture of the present invention; Be specially: activated degasser under the vacuum tightness of in Vakuumkammer, setting makes getter film that getter evapotranspires out attached to waiting to close the sheet glass internal surface in the Vakuumkammer, and then carries out follow-up glass and close sheet.
Further, amount, shape and the position attached to the getter film of glass surface is controlled.
Further, the step of activated degasser is: in the cover that evapotranspires, preset getter, the cover that will evapotranspire is withheld on glass, then getter is carried out heat activation, treats to remove evapotranspire cover and remaining getter after getter film that getter evapotranspires out is attached to glass surface.
Further, control with shape through the size of the cover mouthful of evapotranspiring, cover on different positions on glass attached to the position of glass surface getter film evapotranspiring of passing through to be withheld and control attached to the amount of the getter film of glass surface and shape.
What further, evapotranspire cover mouthful is shaped as long strip shape, circle, rectangle or random shape.
The present invention just activated the processing of evapotranspiring to getter in Vakuumkammer before vacuum glass is shaped, the glass surface after handling through activated degasser adheres to one deck getter film, carries out glass then and closes sheet.The vacuum glass that so produces owing to have getter film in interior surfaces of glass, can reach the absorption gas molecule, keeps the purpose of the vacuum tightness of vacuum glass.In addition,, need not to have saved production process, reduced production cost, also make the vacuum glass of producing more attractive in appearance in grooving on glass owing to do not place getter in the vacuum glass.
Embodiment
Vacuum glass method of manufacture of the present invention; Be specially: (must set the vacuum tightness in the Vakuumkammer before the activated degasser in setting vacuum tightness; Preventing that the getter film that evapotranspires from absorbing causes getter film to lose efficacy behind the gas in a large amount of Vakuumkammers) Vakuumkammer in activated degasser; Make getter film that getter evapotranspires out with predetermined amount, predetermined shape, predetermined position attached to waiting to close the sheet glass internal surface in the Vakuumkammer, and then carry out follow-up glass and close the sheet operation.The step of activated degasser is: in the cover that evapotranspires, preset getter; The cover that will evapotranspire is withheld on glass; Then getter is heated, treat to remove evapotranspire cover and remaining getter after getter film that getter evapotranspires out is attached to glass surface, carry out follow-up glass then and close sheet.Control with shape through the size of the cover mouthful of evapotranspiring attached to the amount of the getter film of glass surface and shape; The shape of covering mouth of evapotranspiring can be long strip shape, circle, rectangle or random shape; The cover mouth that evapotranspires is big more; Amount attached to getter film on glass in identical activationary time is big more, and the cover mouthful more little amount attached to getter film on glass of evapotranspiring is more little, covers on different positions on glass and controls through withholding to evapotranspire attached to the position of glass surface getter film; As required, getter film can be arranged on optional position on glass.
The nonevaporable getter agent also can not adopted the cover that evapotranspires, and the direct heating getter makes the getter film that volatilizes at random attached on glass; Can be employed in the type of heating of getter and to draw electrode on the getter, also can adopt other conventional type of heating through electrically heated.
It is to be noted and any distortion that embodiment according to the present invention has been done all do not break away from the scope that spirit of the present invention and claim are put down in writing.
