Solution for melt pressure of calcium-zinc stabilizer in transparency improvement
Problem Phenomenon
The calcium-zinc PVC system shows melt pressure-related abnormalities in the transparency improvement production stage, the pass rate decreases.
Cause Analysis
The lubrication characteristic of calcium-zinc stabilizers produces melt pressure problems under specific working conditions.
Solution
From the formulation perspective, adjust the calcium-zinc metal ratio, combined with process optimization to solve it.
Key Takeaway
The melt pressure problem of the calcium-zinc system in the transparency improvement stage requires coordinated optimization of formulation and process.
