Abstract
An extrusion equipment adapted for supercritical foaming and mixing of a raw material includes a mixing unit, an injection unit for injection of supercritical fluid into the mixing unit, and an extrusion unit for extrusion of the raw material. The mixing unit includes a tube for input of the raw material, and a propelling screw rod and an auxiliary screw rod that are disposed side by side in the tube and that cooperatively compress and propel the raw material. The auxiliary screw rod rotates at a speed at least twice that of the propelling screw rod and in a direction opposite to that of the propelling screw rod.
