After mixing evenly, cool the raw materials to 40-50°C (to prevent the mixed raw materials from agglomerating). Then add the raw materials to the extruder.

[0013] (2) Heating and extrusion: the extruder is heated to continue to heat the raw materials to 190°C-200°C. The raw materials are mixed in the extruder. The evenly mixed raw materials are pushed to the die of the extruder through the extrusion screw in the extruder. The width and thickness of the die can be adjusted so that the extruded mixed raw materials are flat sheets with a temperature of 180°C-190°C.
