Recycling Process of Wasted Amber from Myanmar

摘要: 采用高温管式炉，研究了缅甸琥珀废弃料的再生工艺，提高颜色差、杂质多的缅甸琥珀的品质，使其具有市场价值。结果表明，缅甸琥珀废弃料需要在无氧条件下进行实验；缅甸琥珀在330~360℃时开始熔融，随着实验温度和保温时间的增加，熔融效果会更好；但在高温实验且保温时间过长时，实验样品的损耗比会变高，降低了工业化经济效益。该方法再生的琥珀：颜色为浅棕黄色至棕黄色，透明，长波紫外荧光下显示蓝色荧光，偏光镜下显示为全亮，密度为1.034 6~1.041 6 g/cm3，在红外光谱中有2 933、2 861、1 723、1 457、1 373、1 225、1 153、1 030、978 cm-1处的吸收峰，且1 723 cm-1处的吸收峰强度低于2 933 cm-1处的吸收峰强度的一半。Abstract: Recycling process of amber from Myanmar was studied by high temperature tube furnace for improving the quality and market value of wasted amber from Myanmar.The results showed that the experiment should do under anaerobic conditions.The amber form Myanmar began to melt at 330~360℃, with the experimental temperature and holding time increasing, the melting effect would be better.When the temperature was higher or the holding time was longer, the loss rate of the amber from Myanmar increased, which would reduce the industrial economic benefits.The colour of recycling amber from Myanmar:light brownish yellow to brownish yellow, transparent, strong bluish violet fluorescence under LW.Crossed polarizer showed full and density is 1.034 6-1.041 6 g/cm3.It has infrared spectrum absorption peaks at 2 933, 2 861, 1 723, 1 457, 1 373, 1 225, 1 153, 1 030, 978 cm-1 and the absorption peak intensity at 1 723 cm-1 is lower than the half that at 2 933 cm-1.
