In the production of PVC carbon crystal panels, stabilizers act as the "guiding star" of the product. Their scientific formulation and process regulation directly impact the final quality of the panels. As market demands for decorative materials continue to rise, precise stabilizer regulation has become a key factor in enhancing product competitiveness.

In practical production, composite calcium-zinc stabilizers are the preferred choice due to their excellent overall performance. Experience shows that controlling the dosage within the range of 4.0-5.0 phr, supplemented with an appropriate amount of epoxidized soybean oil and β-diketone auxiliary stabilizers, significantly improves the thermal stability and weather resistance of the panels. Particularly in the production of dark-colored carbon crystal panels, increasing the stabilizer dosage by 0.2-0.3 phr effectively addresses temperature rise issues caused by heat absorption effects.

Precise control of the processing technology is equally important. By maintaining the production temperature within the range of 175-190°C and reasonably setting temperature gradients across zones, sufficient plasticization of the material can be ensured while avoiding thermal degradation. Maintaining a screw speed of 25-35 rpm not only guarantees production efficiency but also prevents quality issues caused by shear-induced overheating.

It is worth mentioning that stabilizers must also work in synergy with other additives. Adding an appropriate amount of ACR processing aids significantly improves melt strength, while a scientifically designed lubrication system ensures stable material flow. When the formulation contains conductive carbon black, moderately increasing the stabilizer dosage helps maintain system stability.

The quality monitoring phase is indispensable. It is recommended that manufacturers establish a comprehensive quality traceability system, focusing on key indicators such as surface glossiness, thermal shrinkage rate, and conductivity uniformity. Regular thermal aging tests can predict product durability in advance, ensuring that every batch meets quality standards.

Through systematic stabilizer regulation, modern PVC carbon crystal panels not only demonstrate exceptional decorative effects but also achieve breakthroughs in durability and safety. This quality improvement driven by technological innovation is pushing the industry toward higher standards.
