Description

Technical Field

[0001] This utility model relates to the field of gas pressurization technology, and in particular to a gas inflation device for a foaming machine. Background Technology

[0002] Supercritical foaming is a novel material molding technology. Compared to foaming using physical or chemical foaming agents, supercritical foaming requires high-pressure nitrogen or carbon dioxide to be introduced into the reactor. The gaseous substances are liquefied to a supercritical state through high pressure and appropriate heating. The foaming agent and polymer are uniformly mixed through mechanical mixing and the super-strong permeability of the supercritical fluid. After decompression, the system is instantly collided to obtain polymer foamed products.

[0003] Pressurization and gas filling equipment can pressurize and transport gas to the reactor. However, existing pressurization and gas filling equipment relies on manual operation for the pressurization and gas filling process, making it difficult to control pipeline pressure in real time and lacking automation.
