Solution for flame-retardant formulation of calcium-zinc stabilizer in profile extrusion
Fenómeno del problema
The calcium-zinc PVC system shows flame-retardant formulation-related abnormalities in the profile extrusion production stage, customers complain.
Análisis de la causa
The precipitation characteristic of calcium-zinc stabilizers produces flame-retardant formulation 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 flame-retardant formulation problem of the calcium-zinc system in the profile extrusion stage requires bidirectional adjustment of formulation and process.
