Embodiment 1
[0023] Embodiment 1 racemic menthol is used in the extraction and reinforcement method of the site stone armor of the terracotta warriors and horses excavation
[0024] Take by weighing 100 grams of racemic menthol, place it in a 500 milliliter glass beaker, heat and melt it in a 60-degree water bath, and quickly brush the melt with a hairbrush on the stone armor that has been covered with a layer of cotton gauze. During the brushing process, if the ambient temperature is too low, a 1000W infrared lamp can be used to irradiate the surface of the cotton gauze, so that the menthol can penetrate into the stone armor better.
[0025] After the melt has cooled, hold the bottom of the stone armor with your hands, and slowly lift the overall reinforced stone armor out of the excavation site for further restoration.
[0026] With such an amount of menthol, the weight of the stone armor extracted by the above method is 1 kg.
Embodiment 2
[0027] Example 2 Racemic menthol is used for the extraction and reinforcement method of the exhumed painted paintings on the site of terracotta warriors and horses excavation
[0028] Menthol consumption and brushing method are with embodiment 1. The difference is that the peeling paint usually remains on the surface of the soil block. In view of the fact that there are often cracks in the soil clods, in addition to laying gauze on the surface of the remaining painted soil clods, the cracks need to be filled with shredded gauze strips, and the surrounding soil clods should be carefully wrapped with gauze. After the menthol melt is solidified, carefully hold the reserved surface of the gauze, and slowly shovel out the soil block from the original attached layer with a spatula.
[0029] Under such a dosage of menthol, the maximum area of the painted soil clod extracted by the above method is 60×60 square centimeters, and the thickness is 10 centimeters.
Embodiment 3
[0030] Example 3 L-menthol is used in the extraction and reinforcement method of the exhumed painted paintings at the excavation site of Terracotta Warriors and Horses
[0031] Consumption and method are with embodiment 2, and difference is to use L-menthol. Under such an amount of levomenthol, the maximum area of the painted soil clod extracted by the above method is 60×40 square centimeters, and the thickness is 10 centimeters.
