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

With the same screw diameter as in conventional screw extruders, the screw length is reduced, whereby the material residue is reduced, the throughput is increased, the screw motive power is reduced, the temperature control is facilitated to prevent rubber scorching, and extrusion molding of a vulcanizalbe rubber composition is made possible at a lower temperature. In a composite extruding apparatus of rubber, a gear pump 20 is connected to a tip end of a screw extruder 10 via a screen mesh 14 having a breaker plate 15, and a die head 24 is connected to a...

청구항

1. A composite extruding apparatus for extruding rubber comprisinga gear pump connected to a tip end of a screw extruder having a screw having a length L and an outer diameter D via a screen mesh having a breaker plate; a die head connected to an ejecting side of the gear pump, wherein said screw extruder plasticizes a fed rubber composition substantially by friction with an inner surface of a barrel and by friction of said screw and by external heating and extrudes the rubber composition from said screen mesh to a space on an inlet side of said gear pum...
