PA6 Accelerated Conditioning Standard
Sorun Belirtisi
The natural conditioning cycle lasts several weeks, the interior of thick-walled parts cannot be fully penetrated for a long time, and performance test data are scattered
Neden Analizi
PA6 moisture absorption diffuses slowly from the surface to the interior; a 4mm thick part takes more than one year to reach equilibrium at 23°C/50%RH; natural conditioning of thick-walled parts is extremely inefficient and uneven inside and out
Çözüm
①Use accelerated conditioning at 70°C/62%RH according to ISO1110; ②Store thick-walled parts sealed after conditioning to prevent surface water loss; ③Test mechanical property specimens only after unifying the conditioning state
Temel Çıkarım
Accelerated conditioning compresses the PA6 moisture absorption process measured in years into a few days; the ISO1110 conditions are equivalent to the standard atmosphere, and thick-walled parts need sealing to prevent re-drying
