Solution for cooling control of calcium-zinc stabilizer in powder coating
Problem Phenomenon
The calcium-zinc PVC system shows cooling control-related abnormalities in the powder coating production stage, product quality is unstable.
Cause Analysis
The zinc burning characteristic of calcium-zinc stabilizers produces cooling control problems under specific working conditions.
Solution
From the formulation perspective, add antioxidants, combined with process optimization to solve it.
Key Takeaway
The cooling control problem of the calcium-zinc system in the powder coating stage requires bidirectional adjustment of formulation and process.
