High-Efficiency and Stable PS Sheet Extruder

As the core component of the PS underlayment production line, our PS sheet extruder is specifically designed for high-ratio CO₂ foaming technology. It performs the critical task of uniformly mixing PS raw materials with the foaming agent, plasticizing, and steadily extruding the initially foamed slab. Its exceptional performance serves as the foundation for ensuring the superior quality of the final product and the continuous, stable operation of the entire production line.

Core Design Features:

High efficiency PS sheet extruder for KT board production line with stable foaming and mixing

Dedicated High-Efficiency Screw Design: Utilizes a specialized screw with deep flights and a large length-to-diameter ratio, optimized for the viscosity changes of the material after CO₂ injection, providing powerful conveying, shearing, and mixing capabilities.
Ensures molecular-level uniform mixing of the PS melt and CO₂, laying a solid foundation for the subsequent secondary foaming and fundamentally guaranteeing the consistency of the slab density.

Corrosion-Resistant Alloy Barrier Section: The melting section of the screw is made from special corrosion-resistant alloy, effectively resisting acidic substances produced by the decomposition of CO₂ under high temperature and pressure.
Significantly extends the service life of the screw, avoids downtime caused by corrosion, and ensures continuous and stable production.

Unwinding and rewinding system for KT board line gas release before secondary processing

Unwinding & Rewinding System for Gas Release

Our unwinding and rewinding system is strategically integrated between the initial sheeting and secondary foaming stages. Its primary purpose is to manage the rolled material to facilitate the efficient release of internal gases—a critical preparation step that ensures optimal and uniform expansion during the secondary oven foaming process.

Key Operational Advantages:

Controlled Gas Desorption: The system unwinds the initially foamed sheet in a controlled manner, allowing the CO₂ and other blowing agents trapped within the cellular structure to begin desorbing evenly. This prevents the formation of large, uneven bubbles and promotes a consistent cell structure in the final product.

Process Synchronization: It acts as a vital buffer, seamlessly connecting the continuous extrusion process with the batch-oriented secondary foaming stage. This synchronization ensures a smooth material flow, maximizes line efficiency, and prevents bottlenecks.

Preparation for Subsequent Lamination: Following the gas release phase, the rewinding unit neatly recoils the material. This creates a tightly wound, manageable roll that is perfectly prepared for the next downstream process, such as lamination with other layers or packaging.

Core Technologies

Our KT board production line integrates five core processes, combining industry-leading technological capabilities to ensure all-round excellence from substrate to finished product.

High-Proportion CO₂ Physical Foaming Technology

The production line employs a proprietary supercritical carbon dioxide physical foaming system, **achieving a CO₂ injection rate as high as 40%**. Through precise multi-stage pressurization and closed-loop temperature-pressure control, it ensures the efficient and uniform dissolution of a large volume of CO₂ into the polymer melt, forming an extremely fine and uniform microcellular structure. This technology is fundamental to achieving the board's ultra-lightweight nature, excellent thermal insulation, and high specific strength, offering dual advantages in material cost and environmental performance.

Industry-Leading Laminating & Surface Treatment Technology

The line integrates a top-tier precision laminating unit, utilizing multi-roller coordination, constant tension control, and intelligent temperature-pressure bonding processes. This ensures **perfect adhesion between the film and the KT board substrate, resulting in a flawlessly smooth surface completely free from water bubbles or air streaks**. The equipment comes standard with a high-efficiency ionized air anti-static system, **significantly reducing electrostatic buildup caused by friction during production. This eliminates surface defects from dust attraction and enhances operational safety**, ensuring a high-quality visual finish and a safe production environment.

Full-Process Intelligent Synergistic Control System

Powered by an industrial internet-based intelligent control center, the system performs millisecond-level dynamic adjustment and optimization of parameters across the entire process, including high-precision CO₂ injection and laminating. Through algorithmic models, it ensures perfect coordination between all process stages, acting as the "intelligent brain" for stable, efficient production and exceptional product consistency.

High-Efficiency Intensive Mixing Co-rotating Twin-Screw Technology

To address the challenges of high foaming agent injection, the co-rotating twin-screw extruder features an optimized screw configuration and length-to-diameter ratio. Its powerful distributive and dispersive mixing capabilities ensure **thorough and homogeneous integration of the large volume of CO₂ with the melt**, preventing bubble coalescence and collapse, and laying the foundation for uniform nucleation and stable cell growth, while effectively controlling energy consumption.

Precision Multi-Layer Co-extrusion & Gradient Temperature-Controlled Forming Technology

The line utilizes a modular multi-layer co-extrusion die and a multi-zone independent intelligent temperature-controlled forming system. This technology not only enables the production of structurally and functionally integrated boards but, more crucially, provides a precisely controlled pressure and temperature field for the **high-foam-content melt**. This guides the orderly expansion and setting of the cells, ensuring the boards achieve mirror-like flatness and precise thickness tolerance.

These five core technologies are interlinked, forming a complete system. **The combination of 40% high-injection-rate CO₂ foaming and industry-leading laminating technology**, in particular, not only gives the boards an excellent internal structure and physical properties but also guarantees impeccable surface quality and safety. This provides customers with a solid and comprehensive technological foundation for producing high-end, differentiated products.
