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