SMMA Chemical Resistance
Problem Phenomenon
SMMA chemical resistance is good, especially alcohol resistance, but the boundary is clear.
Cause Analysis
SMMA resists weak acids and weak alkalis, alcohol resistance is excellent; but strong solvents attack; stress cracking; use environment; compatibility verification.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Solution
①Utilize the alcohol resistance advantage; ②avoid strong solvents; ③compatibility test; ④stress management; ⑤environment assessment.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
SMMA alcohol resistance is a featured advantage; but the boundary must be managed; verification keeps application safe.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
