Facility for forming one of graphene-polymer resin composite and carbon material-polymer resin composite

A facility for forming one of a graphene-polymer resin composite and a carbon material-polymer resin composite, the facility comprising:

• an extruder that mixes one of graphene and a carbon material with a polymer resin, melts the mixed material, and extrudes the melted material to a filter assembly;
• a heater that is installed on an outer circumferential surface of the extruder to heat the graphene, the carbon material, and the polymer resin;
• the filter assembly that discharges gas generated from the polymer resin and one of the graphene and the carbon material which are extruded from the extruder to the outside;
• and
• an air purification apparatus that removes harmful components in the gas discharged from the filter assembly and discharges clean gas to the outside, wherein the filter assembly includes:
• a housing that has one side on which the molten liquid supply portion is mounted and through which the molten liquid is supplied, and that includes a gas intake and a gas outlet;
• a gas separation portion that is disposed in a longitudinal direction in a hollow formed inside the housing and has multiple flow channels 18 and 34 formed on a surface thereof in a diagonal shape in the longitudinal direction so as to discharge gas contained in the molten liquid in a process in which the molten liquid flows through the flow channels 18 and 34 in a diagonal direction;
• multiple vent rings that are tightly coupled to an outer circumferential surface of the gas separation portion to seal radially outer openings of the flow channels 18 and 34 and thereby preventing the molten liquid from leaking so that the molten liquid flows in the longitudinal direction and the gas contained in the molten liquid is discharged through a micro path;
• and
• a head that is coupled to the other side of the housing to discharge the molten liquid passing through the gas separation portion and presses the multiple vent rings to come into close contact with each other.
