摘要：选择3种充填物香柏油、蓖麻油与液体石蜡来充填祖母绿以掩盖其裂隙且提高透明度,并在不同充填温度及时间下对充填效果进行对比研究。升高充填温度有利于降低充填物黏度,增加其流动性,从而优化充填工艺,充填温度60℃为宜。采用静态注入法与真空注入法进行充填,充填时间1d为宜。相同工艺条件下,充填绿柱石与祖母绿得到的实验结果类似。通过红外光谱检测充填物质,香柏油在3 065、2 957cm-1及2 872cm-1处有特征吸收峰,蓖麻油在3 012、2 927、2 854cm-1处有特征吸收峰,液体石蜡则在2 955、2 924、2 854cm-1处有特征吸收峰。
At different tempertures and changing wood oil, castor oil and liquid paraffin are chosen to viscosity of fillers are 60℃ is found to be a reduced and their flow abi sultable temperature after and vacuum impregnation method are used, condition, similar results are obtained after d lity opt is the filling time, three fill emerald＇s gap and is improved upon inc different fillers including cedar improve its transparency. The reasing the filling temperature imizing the filling process. If static injection method the most suitable length of time. Under the filling the beryl and the emerald. empolyed to characterize the filling materials. The characteristic absorption peaks of at 3 065, 2 957 and 2 872 cm-1 , while those for castor oil are at 3 012, 2 927 and 2 liquid paraffin are at 2 955, 2 924 and 2 854 cm-1.
