PVC Lead Salt Replacement
Fenómeno do problema
Processing fluctuation after switching from lead salt stabilizer system to calcium-zinc
Análise das causas
Calcium-zinc stabilizer has different heat stabilization efficiency from lead salt, changing the process window; during on-site troubleshooting, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solução
Re-calibrate the process window when switching; adjust the lubrication system synchronously; verify with stability tests; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusão principal
Stabilizer switching requires systematic re-verification; 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 similar problems in the future
