Solution for scrap control of calcium-zinc stabilizer in extrusion temperature control
Problem Phenomenon
The calcium-zinc PVC system shows scrap control-related abnormalities in the extrusion temperature control production stage, the pass rate decreases.
Cause Analysis
The thermal stability characteristic of calcium-zinc stabilizers produces scrap control problems under specific working conditions.
Solution
From the formulation perspective, increase auxiliary stabilizers, combined with process optimization to solve it.
Key Takeaway
The scrap control problem of the calcium-zinc system in the extrusion temperature control stage requires coordinated optimization of formulation and process.
