Technical Field

The invention relates to the technical field of plastic material processing equipment, in particular to a novel static mixer.

Background

The extruded polystyrene foam board, also called XPS extruded sheet, is a material formed by continuous extrusion foaming through a special process, hard films formed on the surface of the extruded polystyrene foam board are uniform and flat, the interior of the extruded polystyrene foam board is completely closed and foamed continuously and uniformly to form a honeycomb structure, so the extruded polystyrene foam board has the characteristics of high compression resistance, light weight, no water absorption, air impermeability, wear resistance and no degradation, and is one of cheap and good construction materials in the current building industry. The existing common production mode is that materials are simply mixed through a mixing structure of a screw, when a carbon dioxide combined foaming agent is used as a foaming agent, due to poor compatibility of carbon dioxide, mixing with a material melt is difficult or uneven, so that foam holes in an extruded plate produced by extruded plate equipment are different in size, the compressive strength of the extruded plate is reduced, and unqualified product quality or unstable production process caused by uneven mixing often occur.
