연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A filter media for use in a filter employed to separate water and particulate material from a liquid to be purified, such as a hydrocarbon fuel. The filter media includes a porous material such as glass fiber having a density sufficient to provide the desired mechanical filtration and which carries a water insoluble, water-absorbing material as, for example, a starch-polyacrylonitrile graft copolymer. Also disclosed is a filter employing the media and a method of making the media.

대표
청구항

A water absorbing, mechanical filter comprising: a filter housing; an inlet port in said housing; an outlet port in said housing; said housing further including means defining a liquid flowpath from said inlet port to said outlet port; a body of fibrous material within said housing and extending across said flowpath; and a quantity of starch-polyacrylonitrile graft copolymer dispersed throughout and fixed to said body, the distribution of the graft copolymer within said body being greater nearer said outlet port than said inlet port.
