Description

Technical Field

[0001] The utility model relates to the technical field of strength detection devices, in particular to a device for detecting the residual strength of damaged tempered laminated glass. Background Art

[0002] Tempered laminated glass is a composite glass product made of two or more pieces of tempered glass with one or more layers of organic polymer interlayer in between. After special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure process treatment, the glass and the interlayer are permanently bonded together. Commonly used interlayers for laminated glass are: PVB, SGP, EVA, PU, ​​etc. The residual strength after damage of tempered laminated glass varies greatly depending on the type and thickness of the interlayer used. For example, ordinary PVB tempered laminated glass will produce a large bending deformation once the glass is broken, and there is a risk of the whole piece falling off. Ionic interlayer (SGP) tempered laminated glass has good integrity. The tear strength of SGP interlayer film is 5 times that of PVB interlayer film. Even if the glass is broken, the SGP film can still bond the broken glass to form a temporary structure after the damage. It has small bending deformation and can withstand a certain amount of load without falling as a whole piece.

[0003] The group standard for ionic interlayers stipulates a test method for residual strength after damage. However, there is currently no testing equipment on the market that is suitable for testing the residual strength of tempered laminated glass after damage. It is impossible to intuitively compare the residual strength of tempered laminated glass prepared with ionic interlayers of different thicknesses or types. Utility Model Content
