The structure of existing vacuum glass is made of multi-disc glass 1, intermediate supports 4 arrays and sealing-in limit 3 all around as shown in fig. 1, is closed with vacuum layer 2 between adjacent two sheet glass.Vacuum glass can be made of two sheet glass 1, also can be made of the glass 1 more than three.Certainly, when being constituted by the glass more than three, correspondingly include plural vacuum layer 2 in the vacuum glass naturally.
Exactly because have vacuum layer in the vacuum glass, compare with double glazing, gas molecula number in the vacuum layer significantly reduces, and the collision frequency between the gas molecule, between gas molecule and the glass also reduces thereupon, has intercepted the transmission of heat and the propagation of sound thus.
In order to guarantee the sound-insulating and heat-insulating effect of vacuum glass, the vacuum layer in it need have enough vacuum tightness, and vacuum tightness is more high more good.Usually, the vacuum tightness of vacuum glass should be not less than 10
-1Pa.Consider the prolongation along with duration of service, the vacuum tightness in the vacuum glass can descend to some extent, so, for guaranteeing the validity of vacuum glass, need during making vacuum degree control is being not less than 10
-2Pa, in addition higher.
But along with the raising of vacuum tightness, not only increase the manufacture difficulty of vacuum glass, and can increase cost of manufacture greatly, therefore, under the situation that does not increase vacuum tightness, how to guarantee the sound-insulating and heat-insulating effect of vacuum glass, prolong its work-ing life, become the problem of pendulum in face of people.
Summary of the invention
Problem at the prior art existence, the purpose of this invention is to provide a kind of vacuum glass, this vacuum glass is by arranging central dividing plate in vacuum layer, increased gas molecule passes to heat opposite side glass from the glass of vacuum layer one side as carrier difficulty, simultaneously, also increased the difficulty that sound is propagated between the glass of vacuum layer both sides, thereby, under the situation that does not increase vacuum tightness, the heat-insulating sound-insulating effect of vacuum glass is improved.
For achieving the above object, the present invention has the vacuum glass of central dividing plate and is made by multi-disc glass, have periphery between adjacent two sheet glass by the vacuum layer of sealing-in limit hermetic seal, be provided with the transparent central dividing plate of being made by glass in the vacuum layer, central dividing plate is provided with the intermediate supports array on the both side surface up and down, and by described intermediate supports array central dividing plate and the glassy phase that is located thereon the below are separated, leave the gap between central dividing plate periphery and the described sealing-in limit; Intermediate supports in the described intermediate supports array is made of the projection that central dividing plate up and down adopts calendering technology directly to make on the both side surface, and the central dividing plate intermediate supports on the both side surface up and down is corresponding and be positioned on the same axis one by one.
Further, the gap size between described central dividing plate and the described sealing-in limit is less than the spacing of adjacent two intermediate supports in the described intermediate supports array, and as far as possible little.
Further, described calendering technology is specially: at first the central dividing plate with glass material is heated to the temperature that is suitable for calendering formation, the pressure roller that utilizes a pair of roll surface to be placed with pit then pushes central dividing plate, thus central dividing plate up and down both side surface squeeze out with roller surface on described pit projection one to one.
The present invention is by arranging central dividing plate in the vacuum layer of vacuum glass, vacuum layer is separated into two portions, 1) wants heat transferred opposite side glass with vacuum layer one side glass as the gas molecule of carrier, need walk around central dividing plate, thereby increase the difficulty that heat transmits from structure; 2) intercepted by central dividing plate, the difficulty that gas molecule causes a side glass because of sound vibration propagates into opposite side glass also increases greatly; Therefore, the present invention is improved from the textural heat-insulating sound-insulating effect of vacuum glass that makes.And along with the raising of heat-insulating sound-insulating effect, correspondingly reduced the manufacture difficulty of vacuum glass, also prolonged the work-ing life of vacuum glass.
Intermediate supports is directly made in the central dividing plate upper and lower surface, make central dividing plate become the carrier of intermediate supports array, when making vacuum glass, along with being set, central dividing plate also finished laying of intermediate supports simultaneously, thereby greatly reduce the difficulty that lays of intermediate supports array, reduced the cost of manufacture of vacuum glass.
