Problems solved by technology

The existing double-layer insulation glass production technology is relatively cumbersome, and the high-temperature double-layer glass finished product is cooled in a natural state during the production process. Because the cooling speed is fast, the double-layer glass product is prone to bursting or cracking, and waste Manpower, material and financial resources increase production costs

Embodiment 1

[0043] Taking the outer cup diameter of 10cm of the high-temperature double-layer glass as an example, the cylindrical concave hole 31 of the incubator has a diameter of D 1 Set 14cm, cylindrical concave hole 31 depth H 1 Set 7cm. After cutting, bottom pulling, pressing, sealing and heat preservation for 201~400S, then testing, assembly and packaging. Ensure that other external conditions are the same, repeat production 1000 times, and the probability of defective products such as bursts and cracks in the finished high-temperature double-layer glass is 0.68%.

Embodiment 2

[0045] Taking the outer cup diameter of 10cm of the high-temperature double-layer glass as an example, the cylindrical concave hole 31 of the incubator has a diameter of D 1 Set 14cm, cylindrical concave hole 31 depth H 1 Set 9cm. After cutting, bottom pulling, pressing, sealing and heat preservation for 201~400S, then testing, assembly and packaging. Ensure that other external conditions are the same, repeat production 1,000 times, and the probability of defective products such as bursts and cracks in the finished high-temperature double-layer glass is 0.59%.

Embodiment 3

[0047] Taking the high-temperature double-layer glass outer cup diameter 12cm as an example, the cylindrical concave hole 31 of the incubator has a diameter of D 1 Set 17cm, cylindrical concave hole 31 depth H 1 The setting is 8cm; the finished high-temperature double-layer glass after sealing is inverted and placed in an incubator. After heat preservation for 201-400 seconds, the temperature of the finished double-layer glass drops below 60°C. Ensure that other external conditions are the same, repeat production 1000 times, and the probability of defective products such as bursts and cracks in the finished high-temperature double-layer glass is 0.56%.

Abstract

The invention relates to the field of glass production, in particular to a production process of a double-layer thermal insulation glass. The high-temperature-resistant glass tube is cut, bottomed, pressed, sealed, tested, assembled, packaged, and other steps to produce a finished double-layer thermal insulation glass. In the sealing process of production, the finished high-temperature double-layer thermal insulation glass after sealing is inverted and placed in an incubator for 20 to 700 s for heat preservation. The incubator includes a box body and a box cover. shaped hole, the inside of the box is provided with a thermal insulation block, and a cylindrical concave hole is provided on the thermal insulation block corresponding to the circular hole. The production process of the double-layer thermal insulation glass of the present invention performs thermal insulation treatment on the high-temperature double-layer thermal insulation glass, which can effectively reduce the probability of bursting in the production process of the glass. Compared with the traditional process, the time required by the present invention is shorter, Low energy consumption greatly reduces the production cost.

Description

technical field [0001] The invention relates to the field of glass production, in particular to a production process of a double-layer thermal insulation glass. [0002] technical background [0003] With the gradual improvement of living standards, people have higher and higher requirements for daily necessities, and double-layer thermal insulation glasses are very popular. The existing double-layer insulation glass production technology is relatively cumbersome, and the high-temperature double-layer glass finished product is cooled in a natural state during the production process. Because of the fast cooling speed, the double-layer glass product is prone to bursting or cracking, which is wasteful. Human, material and financial resources increase production costs. Contents of the invention [0004] The object of the present invention is to provide a simple, convenient, high-production-efficiency production process for a double-layer thermal insulation glass that greatly r...
