preparation example Construction

[0052] The upper and lower glasses are prepared from flat glass, and the preparation method further includes: preparing the flat glass into a convex glass by using a mold in a hot bending furnace through the gravity of the glass itself or external pressure.

[0053] The preparation method further comprises:

[0054] The first step is to cut two pieces of flat glass of the required size according to the shape and size of the convex vacuum glass to be produced, and perform edge grinding, chamfering, cleaning and drying;

[0055] In the second step, put the processed two pieces of flat glass into the forming mold, put them into the hot bending furnace, raise the temperature to the softening temperature of the glass, rely on the gravity of the glass itself or the external pressure to make the glass downward to form a convex surface, and then put it into the furnace. When the temperature is lowered to room temperature, the upper and lower glasses in the shape of convex glass are ob...

Embodiment 1

[0240] Embodiment 1: see figure 1 , the vacuum glass is composed of an upper convex glass 1 and a lower convex glass 2, the periphery of the two pieces of glass is welded together by low-temperature glass solder 3, and the middle is a vacuum layer. The production method is as follows: First, cut two pieces of flat glass of required size according to the shape and size of the vacuum glass to be produced, and perform edge grinding, chamfering, cleaning and drying; In the furnace, heat up to the glass softening temperature of 550-750 ° C, rely on the gravity of the glass itself to make the glass downward to form a convex surface, and then drop to room temperature with the furnace; again apply low-temperature glass solder evenly around the periphery of two pieces of glass or one piece of glass, Evenly leave several air holes on the low-temperature glass solder, align the two pieces of glass up and down and stack them together, and send them into the vacuum edge-sealing furnace; fi...

Embodiment 2

[0242] Example 2: see figure 1 , one of the two pieces of glass is low-emissivity glass, and the others are the same as in Embodiment 1.

Abstract

The invention provides convex vacuum glass, which comprises upper glass and lower glass, wherein peripheries of the upper glass and the lower glass are welded together through low-temperature solder; a sealed vacuum layer is formed between the upper glass and the lower glass; the upper glass and the lower glass are convex glass; and the convex surface is toward the outer side. The manufacture method of the vacuum glass disclosed by the invention is simple in process; and with the adoption of the prepared vacuum glass and toughened vacuum glass, the defects in the prior art can be overcome, the gas tightness of the vacuum glass can be effectively ensured, the transparency, the strength and heat-insulation and sound-insulation performances can be can increased, and light pollution of a glass curtain wall also can be reduced.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a vacuum glass and a manufacturing method thereof. Background technique [0002] The existing vacuum glass is generally composed of two pieces of flat glass. The glass is sealed with low-temperature glass solder around the glass, and there is a tiny support in the middle. A thin vacuum layer with a thickness of 0.1-0.2mm is formed between the two pieces of glass through the air extraction hole. Since there is no heat and sound transmission of gas, and the inner surface of the glass can have a transparent low-heat radiation film, the vacuum glass has good heat insulation and sound insulation effects, and is the best energy-saving glass. [0003] The key technologies of the existing vacuum glass include: first, the design of the exhaust hole and the sealing and protection of the exhaust pipe; second, the selection and placement of supports; and the third, the selection and...
