Abstract: PURPOSE: A manufacturing method of a composite material using paper sludge, and a composite film using the paper sludge are provided to recycle wasted sludge by producing a film, a sheet, or an extrudate with the paper sludge. CONSTITUTION: A manufacturing method of a composite material using paper sludge, and a composite film using the paper sludge comprises the following steps: inserting dried sludge and a resin to a mixed extruder, and extruding; cooling the extruded mixture in a water tub in 25~30 deg C; and forming a pellet type chip using a pelletizer. The pressure of the mixed extruder is 50~60 kgf per square centimeters.

Abstract: 본 발명의 PET/PE 필름 폐기물의 재활용 방법은 PET/PE 필름 폐기물을 필름 분쇄기를 이용하여 대략 가로×세로가 1∼3 ㎜ 정도의 크기로 분쇄하고, 상기 분쇄된 PET/PE 필름 폐기물을 호퍼에 투입하여 호퍼로부터 압출기 단부까지의 온도 구배가 240, 255, 255, 255, 250 ℃이고, 압출기의 압력이 50∼53 kgf/㎠ 이고, 스크류의 속도가 1500∼2000 rpm인 조건하에서 압출하고, 상기 압출물을 25∼30 ℃의 수조에서 냉각시키고, 펠렛타이져(pelletizer)에 의하여 펠렛상의 중합물 칩으로 제조하는 단계로 이루어진다. 상기 호퍼로부터 분쇄된 PET/PE 필름 폐기물이 압출기로 투입될 때, 10∼15 kg/hr의 속도로 투입되도록 상기 호퍼 상부에서 가압하는 단계를 더 포함할 수 있다. 필요에 따라, 상기 분쇄된 PET/PE 필름 폐기물을 호퍼에 투입할 때 엘라스토머계 수지나 폴리에틸렌 수지를 더 부가하여 압출할 수 있다.

Abstract: PURPOSE: A recycling method of a polyester/polyethylene film waste and a chip thereof are provided to recycle PET/polyester film waste by manufacturing a polymeric composition chip after directly fusing the PET/PE film waste without separating them into the PET and the PE. CONSTITUTION: A PET/PE film waste is pulverized by using a film pulverizing device. The pulverized PET/PE film waste is injected into a hopper. The temperature gradient is 240, 255, 255, 255, 250°C from the hopper to the extruder end part. The pressure of the extruder is 50~53kgf/cm^2. An extruding process is executed under the condition of 1500~2000rpm screw speed. An extruded product is cooled in the cistern at the temperature of 25~30°C. A polymeric composition chip on pellet is manufactured with a pelletizer.

Abstract: PURPOSE: A composite film and a sheet with self-adhesive property and excellent vapor permeability using fly ash are provided to efficiently block moisture by vacuum-plating the composite film with metal powder. CONSTITUTION: A composite film and a sheet with self-adhesive property and excellent vapor permeability using fly ash are composed as follows. The composite film is molded by adding and extruding fly ash. The composite film improves permeability using the fly ash. When 10% of the fly ash is added, tensile strength is maximized.
