Embodiment Construction

[0025]Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0026] figure 1 A flowchart showing a method for manufacturing tempered and semi-tempered vacuum glass according to the technical solution of the present invention. Figure 2a is adopted figure 1 Schematic diagram of the structure of tempered and semi-tempered vacuum glass manufactured by the method shown. see figure 1 and Figure 2a , in step 100 a series of pre-order operation processing steps are completed. For example, inspect, decontaminate, remove sharp edges, arrange low-emissivity film 8, prefabricate vacuum suction port, place encapsulated getter, etc. on the tempered flat glass used. Although these steps are closely related to the present invention, they are not the core steps of the present invention, but are similar to the corresponding steps in the prior art.

Abstract

The invention discloses tempered/semi-tempered vacuum glass and a method for manufacturing the same. The method comprises the following steps of: selecting two pieces of tempered flat glass as upper and lower base plates of the vacuum glass; uniformly coating glass solders on the surface of the upper base plate or the lower base plate, namely the tempered flat glass, along the edge of the tempered flat glass, wherein the thickness of the glass solders is greater than the height of a used support; performing natural or heating type airing/drying on the coated glass solders, and removing liquid components and volatile solid components to solidify and shape the glass solders; combining the two pieces of tempered flat glass, namely compositing the two pieces of tempered flat glass together; adding the two pieces of tempered flat glass, composited together, into a heating furnace for edge sealing and heating so as to melt the coated glass solders; cooling, and starting to uniformly pressurize the two pieces of tempered flat glass before the glass solders are solidified, so as to enable the thicknesses of the solidified glass solders to be equal to one another and equal to the height of the support in an intermediate layer, and complete the edge sealing of the vacuum glass.

Description

technical field [0001] The present invention relates to a kind of toughened and semi-tempered vacuum glass and its manufacturing method, in particular to a method for ensuring that the final product of vacuum glass can maintain the tempering characteristics of tempered and semi-tempered flat glass to the greatest extent, so as to improve the safety of vacuum glass Performance, so that it can be more widely used in buildings, commercial appliances, thermal insulation doors and windows of refrigeration appliances, locomotive windows, solar energy utilization and other facilities. Background technique [0002] The basic function of vacuum glass is to form a physical layer of heat insulation and sound insulation, which is a new type of energy-saving and environmentally friendly material. It has excellent thermal insulation and sound insulation properties and is widely used in construction projects, especially as the outer envelope structure material of high-end buildings. Ordin...
