차량용 에어필터 Sealing의 NBR일체형 2중구조 및 경질우레탄을 사용한 상하 Cap 개발에 관한 연구
김재열(JaeYeol Kim),윤성운(SungUn Yoon) 한국트라이볼로지학회 2008 한국트라이볼로지학회 학술대회 Vol.2008 No.11
Air filter acts role that remove dust of air that is supplied to automobile engine. There is box in middle of suction system, and Pilteoenrimeonteu includes inside. Terms desired of optimum air filter prevents wear of engine cylinder, and makes ventilating resistance low and improves engine output and secures inhalation of air performance heightening collector efficiency and particulate matter collection amount that is particle exclusion ability of inhalation air. It can be said that Sealing of air filter itself is very important to secure this air filter performance. Because structured itself is large size and engine capacity is big meantime commercial car occasion, used making air filter structure steel cap, but all internal and external import vehicles have made by Urethan filter change into trend that Europe and Japanese occasion have used Urethan recently. Kind is divided by hard urethane 2 kinds if do top and bottom soft property Urethan, top side soft property Urethan. If top and bottom soft property Urethan and top side do soft Urethan, rigid expanded urethane (rubber Type D50 ~ more than 60) has various controversial point. In this research, to heighten several problem improvements and Sealing efficiency lower part uses hard urethane and upper part to hard urethane NBR (rubber mouldings) new technical development that make filter that can be strong and gets duplex Sealing effect because is arrived safe to Mold in the advance and to promulgate rigid expanded urethane do and does so that do solidification target.

As a part of environmental pollution prevention and resources recycling, the regeneration of waste tire has been largely contributed to national industry. But, the worker has been evaded this regeneration process by reason of the best mischievousprocess condition among 3D industries. So, the first, the process condition of regeneratingwaste tire was analyzed. The second, the equipment or system was developed for the improvement of working strength and environment. The last, researchers intend to solve these problems.
