Abstract

본 발명은 폐기물로 오염된 폴리스티렌을 오염제거하는 방법에 관한 것으로서, 그 오염된 물품을 액상 스티렌 단량체내에 용해시키는 단계, 및 그 오염물-제거된 용액을 회수하는 단계로 구성된다.The present invention relates to a method for decontaminating polystyrene contaminated with waste, comprising dissolving the contaminated article in a liquid styrene monomer and recovering the contaminant-depleted solution.

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

Claims (5)

(a) 폐기물 오염된 폴리스티렌 물품을 그 오염물의 거의 불용성인 스티렌 단량체의 용매 작용하에 두어 폴리스티렌 물품-스티렌 단량체 용액을 형성하도록 단계; 및 (b) 상기 오염물-제거된 용액을 회수하는 단계로 구성되는 상기 폐기물 오염된 폴리스티렌으로부터 폴리스티렌 물품을 정제하고 회수하는 방법.(a) placing the waste contaminated polystyrene article under the solvent action of a substantially insoluble styrene monomer of the contaminant to form a polystyrene article-styrene monomer solution; And (b) recovering the contaminant-depleted solution. 제1항에 있어서, 상기 폴리스티렌 물품은 폴리스티렌임을 특징으로 하는 방법.The method of claim 1 wherein the polystyrene article is polystyrene. 제1항에 있어서, 상기 오염물-제거된 용액은 여과로 회수됨을 특징으로 하는 방법.The method of claim 1 wherein the contaminant-removed solution is recovered by filtration. 제1항에 있어서, 상기 회수된 오염물-제거된 용액은 스티렌으로부터 폴리스티렌을 제조하는 대량 현탁법 또는 대량 연속 공정법에서 공급원료의 적어도 일부로서 사용됨을 특징으로 하는 방법.The method of claim 1 wherein the contaminant-removed solution recovered is used as at least part of the feedstock in a bulk suspension or mass continuous process to produce polystyrene from styrene. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
