Abstract

본 발명은 압출기 및 표면을 구조화하는 로을러를 함유하는 3롤 폴리싱 스택(three roll polishing stack)이 장착된 압출 시스템을 사용하여 매우 정교하게 구조화된 표면을 갖는 플라스틱 판을 압출시키는 방법에 관한 것이다. 시스템은 동시 압출용으로 고안되고 플라스틱 판은 고점성 기본 성형 화합물 BF 및 BF상에 압출되는 저점도 성형 화합물 NF로부터의 동시 압출물 CX로서 2개의 압출기를 통해 제조된다. 판의 표면은 3롤 폴리싱 스택을 통해 구조화된다. 본 발명의 방법에 의해 제조된 프레넬 (Fresnel)렌즈를 태양열 수집기에 사용할 수 있다.
