METHOD FOR GLUEING DETAILS OF ALUMINIUM ALLOYS TOGETHER WITH FOAMED POLYURETHANE OF WITH UNWOVEN MATERIALS Russian patent published in 1994 - IPC

FIELD: glueing. SUBSTANCE: adhesive is applied on glued surfaces then particles of foamed polyurethane having 0.5-1.5 mm in size are applied on said adhesive. The process is followed by drying at 45-60 C and humidity 70-90% , duration of the process is 2 h. Then adhesive is applied, sustained within 15-30 s and fixed at specific pressure 0,15 kg/cm². The process is followed by drying at 30-40 C with the help of infrared irradiation at wavelength 2-0.5 mm. Drying takes place within 30 min. EFFECT: improves efficiency of the method. 1 tbl, 2 dwg
