PA12 Product Chemical Resistance
Problem Phenomenon
Chemical environment application.
Cause Analysis
PA12 has excellent oil resistance; but media such as strong acids still need verification.; During on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based solely on experience; This mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Confirm compatibility according to the medium; ②do immersion test; ③avoid incompatible media; ④select chemical-resistant grade.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PA12 oil resistance is an advantage; be cautious in strong acid environments.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; Include this case in the defect archive as a troubleshooting reference for subsequent similar problems
