Solution for whitening scheme of calcium-zinc stabilizer in regrind proportion
Fenómeno del problema
The calcium-zinc PVC system shows whitening scheme-related abnormalities in the regrind proportion production stage, the pass rate decreases.
Análisis de la causa
The precipitation characteristic of calcium-zinc stabilizers produces whitening scheme problems under specific working conditions.
Solución
From the formulation perspective, adjust the calcium-zinc metal ratio, combined with process optimization to solve it.
Conclusión clave
The whitening scheme problem of the calcium-zinc system in the regrind proportion stage requires bidirectional adjustment of formulation and process.
