Embodiment Construction

[0029] First process the bamboo plant fiber into micropowder, then put the bamboo powder into the mixer, heat up and dry by external heating, remove a lot of water in the bamboo powder, then add coupling agent for surface treatment, and then add PVC resin powder , and then add heat stabilizer, lubricant, foaming regulator, and foaming agent in order, and mix evenly; add a cooling water jacket connected to the die die, and shorten the die core by 10cm; connect the extruder and The mold, cooling and shaping device, traction device, and cutting device are coordinated; set the temperature of the barrel and die head, turn on the cooling water jacket, cooling and shaping device, pulling device and cutting device, and put the mixed ingredients into the cone double extruder. Set the discharge temperature, the screw speed of the conical double extruder, and the feeding speed to produce bamboo-plastic foamed materials with a smooth surface without skinning and loose foaming inside. Acco...
