Method for in-situ reinforcement and restoration of unearthed decayed ivory
The invention discloses a method for reinforcing and repairing unearthed decayed ivory in situ. The method comprises the following steps: S1, dehydrating an ivory to be reinforced; s2, a certain amount of calcium source and anhydrous citric acid are weighed and dissolved in deionized water to obtain a mixed calcium source solution A, a certain amount of phosphorus source is weighed and dissolved in deionized water to obtain a phosphorus source solution B, and the molar ratio of Ca < 2 + > in the solution A to PO4 < 2-> in the solution B is 1.66-1.68; and S3, the calcium source solution A and the phosphorus source solution B are dropwise added to the dehydrated to-be-reinforced ivory to make the to-be-reinforced ivory permeate, a certain amount of ammonia water and the to-be-reinforced ivory are placed together and sealed, the ammonia water volatilizes to adjust the pH, and hydroxyapatite is generated on the to-be-reinforced ivory in situ. According to the method, hydroxyapatite is generated in situ on the ivory to be reinforced by adopting a fumigation method, the ivory cannot be damaged, and the reinforcing effect is better. Hydroxyapatite is synthesized at the room temperature, ivory is reinforced at the room temperature, the conditions are mild, and the requirements of cultural relic protection are met.
本发明公开的一种原位加固修复出土糟朽象牙的方法，包括如下步骤：S1、将待加固象牙进行脱水处理。S2、称取一定量的钙源和无水柠檬酸溶解在去离子水中得到混合钙源溶液A，称取一定量的磷源溶解在去离子水中得到磷源溶液B，溶液A中Ca2+与溶液B中PO42‑的摩尔比为1.66‑1.68；S3、将钙源溶液A和磷源溶液B滴加到脱水处理后的待加固象牙上使其渗透，取一定量的氨水与待加固象牙放置在一起并封闭，氨水挥发调节pH，使羟基磷灰石在待加固象牙上原位生成。本发明采用熏蒸法在待加固象牙原位生成羟基磷灰石，不会对象牙进行损坏，并且加固效果更好。在室温下合成羟基磷灰石以及在室温下加固象牙，条件温和，符合文物保护的要求。
