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