PPO Thermal Decomposition and Corrosive Gas
Sorun Belirtisi
【Problem Phenomenon】After PPO processing temperature goes out of control, corrosive gas appears, equipment is damaged and personnel feel unwell
Neden Analizi
PPO decomposes very easily and produces corrosive gas when decomposing, so molding temperature should be strictly controlled; over-temperature decomposition both destroys the material and corrodes the equipment; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Çözüm
Strictly control temperature within the window and set over-temperature alarms; regularly calibrate the heating system against drift; when decomposition signs appear, immediately shut down, cool down and troubleshoot; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Temel Çıkarım
PPO over-temperature decomposition releases corrosive gas; temperature control alarms are double insurance for equipment and personnel; 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
