POM barrel residence decomposition
Fenómeno do problema
After a short shutdown and restart, products yellow and have a sour odor.
Análise das causas
POM remaining in the barrel continues to decompose when heated; if the machine is stopped without cooling down or purging, the decomposition products contaminate subsequent products and corrode the equipment.
Solução
①If shutdown exceeds 10~15 minutes, cool down or purge immediately; ②fully purge at startup; ③clean the barrel; ④avoid long residence of small parts on large machines.
Conclusão principal
POM shutdown = immediate handling, delay means decomposition.
