ASA Low-Temperature Toughness
Problem Phenomenon
ASA impact strength may decrease at low temperatures, low-temperature application evaluation.
Cause Analysis
ASA may not be tough enough under certain conditions; impact strength decreases at low temperatures; application environment; modification selection; safety assessment; test verification.; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Solution
①Low-temperature application evaluation; ②modified grades; ③impact test; ④safety design; ⑤environmental matching.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ASA low-temperature toughness is an application boundary; equal emphasis on modification and testing; evaluation ensures safe use.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
