Abstract：The causes and mechanisms of aluminum alloy adhesion for 3003 curtain wall panels were studied by metallographic observation,scanning electron microscopy(SEM),energy spectrometer(EDS)and other analytical detection and characterization methods.The results show that the annealing and sticking mechanism of aluminum strip 3003 curtain wall is correlated with the coarse grain structure and uneven distribution of the second phase in terms of microstructure.The unreasonable annealing process and the unreasonable design of the degreasing stage in the annealing process make the degreasing unclean is the key to sticking.Based on this,preventive and control measures such as precise control of annealing temperature,reasonable setting of holding time,improvement of furnace loading method,correct use of cold rolling lubrication conditions,and control of grain size of cast and rolled slabs to ensure the uniformity of curtain wall aluminum plate product structure are proposed.
