During field development of a microgrout for the stabilization of painted lime plasters detached from a limestone substrate, diethyl oxalate-based formulations out-performed microgrouts based on nanolime, colloidal silica and ammonium oxalate, creating more cohesive and homogenous set materials, with better working properties. However, unlike ammonium oxalate, diethyl oxalate is relatively new to the field of conservation, and therefore requires extensive testing to understand its properties and the products of its reaction in calcium carbonate systems before it can be used in conservation treatments. The current study builds on previous testing, to compare the effect of variations in the formulation of diethyl oxalate-based microgrouts bulked with limestone powder, including the effect of application to dry and damp limestone substrates to understand its reaction mechanism, products and performance.

碳酸钙系统中草酸二乙酯基微泥浆:配方和应用参数

在用于稳定从石灰石基材上剥离的已涂石灰石膏的微灌浆的现场开发过程中,草酸二乙酯基配方的性能优于基于纳米石灰,胶体二氧化硅和草酸铵的微灌浆,从而产生了更具粘性和均质的固化材料,并具有更好的工作性能。然而,与草酸铵不同,草酸二乙酯在保护领域相对较新,因此在用于保护处理之前,需要进行广泛的测试以了解其性质及其在碳酸钙体系中反应的产物。当前的研究建立在之前的测试基础之上,旨在比较以石灰石粉为原料的草酸二乙酯基微浆的配方变化,
