Embodiment Construction

[0034] The present invention is further described below in conjunction with specific embodiments: the vacuum glass manufacturing method of the described rear support, taking two glass plates combined to produce vacuum glass without an air suction nozzle as an example, includes the following steps carried out in sequence:

[0035] The first step is to place two rectangular toughened glass plates with smooth surfaces and the same shape in a vacuumable heating chamber, and heat the heating chamber to 300°C±50% to exhaust the glass plates at high temperature;

[0036] In the second step, when the temperature of the glass plate after high-temperature exhaust is cooled to 150°C±50% (or the temperature range is ≥100°C and ≤200°C), solder is placed on the sealed area of ​​the inner edge of the tempered glass plate, two pieces There is no need to arrange air nozzles between the tempered glass plates. Of course, in order to prolong the service life of the product and maintain the vacuum ...

Abstract

The invention discloses a later-support vacuum glass manufacturing method which comprises the following steps: cooling after high-temperature exhaustion; laying a soldering flux at a preset sealing area when the temperature is cooled to 150 DEG C; directly superposing two glass plates in parallel without set supports; raising the temperature to 200 DEG C, welding the soldering flux and sealing the edge; cooling to 150 DEG C and selecting points from one or two surfaces to carry out laser fixed-point irradiation after close welding to ensure that bulges are formed between the two glass plates at the irradiation points; and forming support between the two glass plates by bulges formed by one or more points. The later-support vacuum glass manufacturing method has the advantages of abandoning the complicated manner of previously laying a support, greatly improving the vacuum degree, simplifying the manufacturing process and improving the wind-resistant performance of the vacuum glass.

Description

technical field [0001] The invention relates to an isolation component, in particular to a method for making a back-supported vacuum glass that can effectively improve the degree of vacuum. Background technique [0002] Vacuum glass is widely used in architecture and engineering construction, the typical vacuum glass used in modern buildings, its sound insulation and heat insulation effect is much better than ordinary insulation materials, so it is more and more popular in the field of modern architecture and structure Pay attention to. The key to the performance of vacuum glass lies in the vacuum degree of the vacuum isolation layer, and the vacuum isolation layer only needs a few microns to play a role. The current manufacturing process of vacuum glass is to place and fix supports on a flat plate, spread solder on the edge between two parallel plates, arrange and install air extraction nozzles, then weld and seal at high temperature, and finally evacuate to form a vacuum....
