폐자기 기록테이프에서 폴리에스테를 필름의 회수방법Method of recovering polyester film from waste magnetic recording tape

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 공정도이다.1 is a process diagram of the present invention.

Claims (1)

폐자기기록테이프를 화학약품을 이용하여 P.E 필름을 회수하는 방법에 있어서, 2-5% 알카리용액(PH. 11)이 침지된 탱크를 70℃의 온도에서 폐자기기록테이프를 5-10분간 통과시켜 자성체와 P.E필름을 이완 시킨 후 로울러를 이용 이완된 자성체를 분리하고 2-5%의 산성용액이 저장된 탱크에서 통과시켜 PH 6.5-7.5로 중화시킨후 1-2%의 중성세제가 포함된 탱크를 통과시켜 세척하고, 탈수, 건조, 되감는 공정을 연속 공정으로 함을 특징으로 하는 폐자기기록테이프에서 폴리에스테르 필름의 회수방법.In the method of recovering the PE film using chemicals, the waste magnetic recording tape is passed through the waste magnetic recording tape at a temperature of 70 ° C. for 5-10 minutes through a tank in which 2-5% alkaline solution (PH. 11) is immersed. After loosening the magnetic material and PE film, separate the loose magnetic material by using a roller, pass it through the tank containing 2-5% acid solution, neutralize it with PH 6.5-7.5, and then contain 1-2% neutral detergent. The method of recovering a polyester film from a waste magnetic recording tape, characterized in that the washing through, washing, dehydration, drying, rewinding in a continuous process. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
