Q

PA6 Post-Drying Storage Time Limit

A

Dried material has a storage time limit, and overtime material must be re-dried; heat preservation does not equal continuous drying; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a refe...

Q

PA6 Flame-Retardant Grade Drying

A

The drying temperature of flame-retardant grades is limited by the temperature resistance of the flame retardant, and conventional conditions cannot be copied directly; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence

Q

PA6 Color Masterbatch Carrier Drying

A

The moisture brought in by color masterbatch is often overlooked, and synchronous drying with the base material is a necessary measure; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a r...
