polyisobutylene sealant YD-8690 for insulating glass - Production method
P> the glued aluminum strip and glass shall be scrubbed clean, keep the glue strip connected continuously during gluing, and eliminate the open circuit caused by bubbles. glue shall be glued within 1~2 hours after extrusion. a special thermoplastic gluing machine must be used on the vacuum glass production line to put the glue into a glue cylinder, heat to 110~130 ℃, exhaust and extrude at the same time, extrude at the same time, extrude, after the two pieces of glass are bonded, they are extruded and shaped. During manual work, a rubber strip can be made and pasted on an aluminum strip for bonding.
