AI Technical Summary
The injection of supercritical fluid into traditional polystyrene foam materials leads to uneven fluid dispersion, resulting in local oversaturation or undersaturation. This affects the material strength and causes significant differences in bubble size. Furthermore, the fluid and melt have insufficient compatibility, resulting in interface defects.
Multiple injection components are installed on the top of the extrusion unit to inject supercritical fluid at different positions. The fluid is atomized into micron-sized bubbles using micro-jet nozzles, and the fluid distribution is adjusted in real time by monitoring components to ensure uniform injection.
It improves the distribution uniformity of supercritical fluids, increases bubble density and material impact strength, eliminates interface defects, reduces the standard deviation of tensile strength, and meets the material uniformity requirements for high-end electronic packaging and precision instrument cushioning.
