Solution for precipitation blooming of calcium-zinc stabilizer in extrusion temperature control
Problem Phenomenon
The calcium-zinc PVC system shows precipitation blooming-related abnormalities in the extrusion temperature control production stage, product quality is unstable.
Cause Analysis
The zinc burning characteristic of calcium-zinc stabilizers produces precipitation blooming 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 precipitation blooming problem of the calcium-zinc system in the extrusion temperature control stage requires bidirectional adjustment of formulation and process.
