Description

technical field [0001] The invention relates to injection molding equipment, in particular to supercritical fluid-assisted microporous injection molding equipment. Background technique [0002] Microcellular polymer refers to the cell size of 1 ~ 100μm, cell density of 10 9 ~10 15 piece / cm 3 foam polymer. The cells of microporous polymers are extremely small and evenly distributed, making the microvoids in the polymer circular, which plays a role of toughening and strengthening, so microporous polymers can not only save materials, but also have some mechanical properties even better than Non-foaming polymer. Compared with traditional blowing agents, supercritical fluids (CO 2 , N 2 etc.) have the advantages of good stability, low cost, and no environmental pollution. However, how to inject supercritical fluid stably into a high-temperature and high-pressure injection molding machine, and within a limited time and barrel length, make the supercritical fluid evenly dispe...
