The removal of environmental stains from a pigmented maxillofacial elastomer was carried out by solvent extraction under network swelling. Silastic 44210 was pigmented with 11 maxillofacial pigments prior to staining. Samples were stained with lipstick, methylene blue, and disclosing solution. These stains were then removed by solvent extraction with 1,1,1-trichloroethane. Color parameter measurements both before and after staining and after solvent extraction demonstrated the effectiveness of removing these stains by solvent extraction while causing little or no change in the color of the pigmented samples.
通过在网络溶胀下进行溶剂萃取，去除色素沉着的颌面弹性体上的环境污渍。在染色之前，用11种颌面色素对硅橡胶44210进行色素沉着。样本用口红、亚甲蓝和示踪液进行染色。然后用1,1,1-三氯乙烷通过溶剂萃取去除这些污渍。染色前后以及溶剂萃取后的颜色参数测量表明，通过溶剂萃取去除这些污渍是有效的，同时色素沉着样本的颜色几乎没有变化或没有变化。
