Airtightness test device and test method for insulating glass

Abstract

The invention provides an airtightness detecting device and method for hollow glass. The device comprises a box, a box cover, a pressure gauge, a heating device and a temperature detecting device. The box is movably connected with the box cover. A filling port is formed in the box. The heating device is mounted in the inner cavity of the box. The pressure gauge and the temperature detecting device are respectively communicated with the inner cavity of the box. The method includes: placing the hollow glass into the inner cavity of the box, and connecting the box cover and the box in a sealed manner; filling the inner cavity of the box with testing water under the pressure reaches more than 40KPa, and heating the testing water to above 15 DEG C; maintaining pressure; acquiring airtightness testing result. The airtightness detecting device and method has the advantages that simple operation is achieved, high testing result reliability is achieved, hollow glass maintenance quality and airtightness detecting efficiency are increased, hollow glass airtightness detecting cost is lowered greatly, and product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air leakage detection of insulating glass, in particular to an airtightness inspection device and inspection method of insulating glass. Background technique [0002] Most of the current railway passenger car window glass is made of insulating glass, which is formed by bonding two opposite glass sheets to an aluminum alloy frame containing a desiccant through a high-strength, high-air-tight composite adhesive. It is a high-efficiency glass with good heat insulation and sound insulation performance, beautiful and practical, and can reduce its own weight. [0003] When the operation of the railway passenger car reaches the specified operating mileage or service life, the window must be disassembled and overhauled as a whole, and the insulating glass on it also needs to be re-checked or overall updated. At present, after the insulating glass is disassembled, reassembled or overall updated, only the overall ...

AI Technical Summary

Problems solved by technology

However, since the rain test is more focused on verifying the tightness between the insulating glass and the window frame strip, it is difficult to verify the airtightness between the two panes of the insulating glass

If the insulating glass leaks during the operation of the railway passenger car, it will seriously affect the running quality of the railway passenger car

In addition, due to the special structure of insulating glass, the production and delivery of insulating glass also require corresponding air tightness tests to ensure the product quality of insulating glass. However, the existing detection methods for insulating glass are poor and the detection efficiency is low. lead to higher testing costs
