Differential elastic modulus support column array and vacuum glass

Abstract

The invention discloses a differential elastic modulus support column array and vacuum glass. In the differential elastic modulus support column array, support columns of a first round near sealing edges of the vacuum glass are low-elasticity modulus support columns, and support columns of a second round near the sealing edges of the vacuum glass are high-elasticity modulus support columns. Similarly, in a direction away from the sealing edges of the vacuum glass, rounds of low-elasticity modulus support columns and rounds of high-elasticity modulus support columns are alternately arranged until the support columns are all arranged. The vacuum glass is formed based on the differential elastic modulus support column array and plate glass. The differential elastic modulus support column array of the invention can reduce the maximum stress and maximum deformation of the vacuum glass, thereby reducing glass damage and support column vacancies. The effect of the arrangement of the differential elastic modulus support columns is established under the condition that the original array spacing of conventional product support columns is constant or under the condition of array spacing of support columns of novel design.

Description

technical field [0001] The invention relates to the technical field of vacuum glass, in particular to a differential elastic modulus support column array and vacuum glass, which is suitable for the manufacture of flat vacuum glass. Background technique [0002] The two pieces of flat glass of the vacuum glass are supported by supporting columns arranged in an array to form a gap; the four peripheries of the two pieces of flat glass are sealed with edge-sealing materials to form an edge; and vacuum is drawn from a preset hole on a piece of flat glass. Sealing forms a vacuum in the gap between two sheets of flat glass; the above-mentioned process and material combination form a flat type vacuum glass (abbreviated as vacuum glass). Among them, edge sealing not only refers to the process of sealing the surroundings of the vacuum glass, but also refers to the structure formed by the edge sealing material and the glass to which it is bonded. Vacuum prevents the heat conduction an...

Problems solved by technology

At this time, it may cause the support column to pierce the glass, resulting in damage to the glass, and in severe cases, it will burst.

Second, the span of the glass between the two supporting columns is increased. Due to the small vacuum gap, the glass will be deformed by force, and the glass itself has a certain degree of unevenness, resulting in two pieces of flat glass contacting, that is, "glass bonding" Phenomenon, such direct contact heat transfer between the glass, lost the effect of vacuum insulation

When the deformation is too large (including the unevenness of the flat glass itself), some support columns will not be fully compressed, and the support columns will move to other positions, resulting in the common phenomenon of support column vacancy (that is, there is no support column in the array position)
