| 제목 | Saving Energy and Efficient Extraction of Binder Materials from Powder Injected Metals using Supercritical CO2 |
| 초록 | Extraction method using supercritical carbon dioxide (scCO2) is an efficient and safe extraction method. ScCO2 has high density like liquid and low viscosity like gas. On typical thermal debinding method, it often requires long time and high temperature around 200oC that can consume large amount of energy, resulting high cost of final products. In this study, polymers were firstly prepared and checked solubility in scCO2 at different conditions. Then, the checked polymers were used as binders in the binding process of metal injection moulding. After extraction of polymer binders by scCO2, final products are commonly component items and are used in various industries and applications. This method is green, fast, cheap and easy to scale-up.
