To ensure the quality of insulating glass, it is necessary to do more tests and inspections during the processing. Before construction, it is necessary to ensure that the hollow glue and the substrate have good adhesion, and to carry out adhesion test and compatibility test.

Among them, the adhesion test is to confirm whether the hollow glue and the substrate are well bonded; and the compatibility test is to avoid adverse chemical reactions between the glue and glass, spacers and accessories.

In the process of processing, continuous extrusion test, butterfly test, pull-off time test, etc. are also carried out. Among them, the purpose of the butterfly test is to determine whether the components A and B are mixed evenly; the purpose of the break-off time test is to determine whether the mixing ratio of components A and B is normal.

In addition, check the quality of the glue injection.

For the processed insulating glass, in order to confirm the bonding quality between the glue and the substrate, a rubber tapping and peeling test is also required. The purpose is to confirm the bonding quality of the glue and the substrate, and to ensure the quality and safety of the finished insulating glass.
