Polyethylene Glycol을 첨가한 고가소성 점토 연구

Study on Highly Plastic Clay by Polyethylene Glycol

본 연구에서는 유기물을 점토에 물리·화학적으로 복합화를 통하여 물성이 향상된 도자기 소지를 개발하여 생활식기 제조에 적용하였다. 본 기술은 생활식기용 도자소지에 가소제 Polyethylene Glycol(PEG)를 첨가하여 가소성을 증진시키고 개량된 소지를 사용하여 제조된 식기의 품질 특성의 변화를 관찰하였다. PEG 첨가량이 0.5wt.% 이상에서 가소성이 현격히 증가하였으며 충격강도 역시 소지의 가소성 증진에 의하여 증가한다는 사실을 알 수 있었다.

In this study, porcelain materials with improved physical properties were synthesized by physically and chemically composing organic material into clay and applied to the manufacture of living tableware. The plasticized polyethylene glycol(PEG) was added to the porcelain materials for living tableware to improve the plasticity and the change of the characteristics of the tableware made using the modified material was observed. It was found that the plasticity was remarkably increased at the PEG content of 0.5wt.% or more and the impact strength was also increased by the plasticity of the material.
