ASA Antistatic Modification Application
Problem Phenomenon
【Problem Phenomenon】Electronic equipment enclosures need antistatic and weather resistance
Cause Analysis
ASA can be modified with antistatic agents or conductive fillers; outdoor electronic equipment dust-proof and anti-static accumulation; weather resistance needs re-verification after modification; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Solution
Antistatic needs choose modified ASA grades; surface resistance verified according to standards; modified grades weather resistance re-tested; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ASA antistatic modification is usable, weather resistance re-verification cannot be omitted; after confirming effectiveness, fix 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
