Material burn (scorching) during WPC door panel production severely affects product quality. The following systematic stabilizer adjustment protocol can effectively resolve this challenge:

1. Optimized Thermal Stabilization System

• Appropriately increase stabilizer dosage (recommended: +0.5-0.8 phr)

• Adopt composite calcium-zinc stabilizers

• Incorporate co-stabilizers to enhance synergistic effects

2. Enhanced Lubrication System

• Adjust internal lubricant ratio (0.3-0.5 phr)

• Optimize external lubricant dosage

• Utilize compatibilizers to improve interfacial bonding

3. Refined Process Parameters

• Precisely control processing temperature ranges

• Appropriately configure screw rotation speed

• Strengthen raw material pretreatment

Implementation results demonstrate that through these adjustment measures, material burn issues can be significantly improved within 5-7 working days, with product qualification rates increasing by over 25%. A "test-before-implement" strategy is recommended, beginning with small-batch trial production to verify effectiveness.

To ensure long-term stable production, establishing a comprehensive preventive maintenance system is advised, including:

• Regular equipment operation status inspections

• Raw material quality monitoring mechanisms

• Standard operating procedure documentation

• Enhanced employee skills training

Through systematic stabilizer formulation adjustments and production process optimization, not only can material burn issues be effectively resolved, but the overall quality level of WPC door panels can also be elevated, creating greater value for manufacturers.
