Improper annealing treatment, residual stress not eliminated or product deformed
Sorun Belirtisi
Improper annealing treatment, residual stress not eliminated or product deformed
Neden Analizi
Annealing temperature set improperly (too high deformation/too low ineffective)
Annealing time insufficient, residual stress not fully eliminated
Annealing environment temperature uneven
Cooling too fast after annealing, introducing new stress
Cellulose acetate butyrate annealing temperature should be 15-20°C below the heat deflection temperature
Çözüm
Set the annealing temperature to 15-20°C below the heat deflection temperature
Annealing time 1-2h, adjusted according to wall thickness
Ensure the annealing environment temperature is uniform
Cool slowly after annealing
Cellulose acetate butyrate annealing can effectively eliminate residual stress
Temel Çıkarım
Annealing requires slow cooling below the heat deflection temperature
