Problems solved by technology

The disadvantages of this process are: 1. The energy consumption of the third heating is high
2. Repeated heating leads to glass deformation, and the product yield is low
3. The suction hole has a large suction resistance and is difficult to vacuum
Due to the existence of air extraction holes, it is difficult to install and transport, and also affects the overall aesthetics
Although the Chinese patent No. 98118099.x has no air vent, it has poor durability and low practical value because it is sealed with silicon rubber.

Embodiment Construction

[0042] The present invention will be described in detail below in conjunction with the accompanying drawings. The vacuum glass of the present invention is shown in Figure 3. The vacuum glass consists of an upper and lower glass plate 6, a support body 5 sandwiched between the upper and lower glass plates, and two glass plates. The sealing body 7 constitutes. Compared with the existing vacuum glass (as shown in Figure 1 ) sealed with welding glass powder, the existing vacuum glass has air vents 3, and the vacuum glass manufactured by the present invention does not have air vents, and other parts are the same.

[0043] As shown in Figure 4, place the vacuum glass original plate with welding glass powder and support in the sealable heating chamber 9, the vacuum system and the sealable heating chamber are connected through pipelines, and there is a heating device in the sealable heating chamber 9 10. The heating device 10 is the heating part of the heating device, which uses resis...

Abstract

The vacuum glass formed through a one-step process consists of two glass plates, supporting pieces between two glass plates and sealing bodies around two glass plates, and features no air pumping holes. Its making process includes the following steps: setting glass plates and other parts, heating and vacuumizing, sealing, and cooling. The making process features that the vacummizing is completed through the gaps in welding glass powder and the gaps are sealed automatically after the glass powder is molten.

Description

Technical field: [0001] The invention relates to the technical field of flat vacuum glass manufacturing, in particular to one-step forming vacuum glass and its manufacturing method and equipment. Background technique: [0002] Over the years, through the efforts of technicians, the flat vacuum glass has entered the stage of industrial production. The existing vacuum glass manufacturing technology is very cumbersome, basically the following process is required: cleaning and cutting - making air extraction holes - placing supports and welding glass powder ——Heating and welding——Vacuumizing——Blocking the air hole——Cooling——Inspection and storage. For example, the Chinese patent No. 99801553.9 of Qingdao Xinliji Technology Application Co., Ltd.: vacuum glass manufacturing method and its device. The Chinese patent No. 200380108877.2 of Nippon Panglass Co., Ltd. is a patent for the manufacture method of vacuum glass panel and the vacuum glass panel manufactured by this method. T...
