Understanding the Micro Supercritical CO₂&N₂ Injection Machine
The Micro Supercritical CO₂&N₂ Injection Machine, developed by China Feininger, is a cutting-edge equipment designed to inject CO₂ as a blowing agent into the polymer melt during extrusion processes. Its key features and working principles include:
CO₂ as Blowing Agent: The machine utilizes CO₂ as a blowing agent, which is injected into the barrel screw by a high-pressure injection pump. This controlled injection process ensures uniform foaming and enhanced product properties.
Constant Volume Flow Rate and Pressure: During extrusion, the machine maintains constant volume flow rate and pressure of CO₂ gas, leading to consistent foaming and improved quality of the final product.
Supercritical State Formation: Through shear mixing of the screw and convection and diffusion of the gas, the polymer in the barrel reaches a supercritical state. This supercritical state enhances mixing, dispersion, and foaming efficiency.
Pressure Drop and Rapid Nucleation: As the polymer reaches the head of the supercritical CO₂ injection equipment, a pressure drop occurs, leading to rapid nucleation and foam formation. Cooling after nucleation results in the final product with desired properties.
