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