石材表面锈黄斑的中性清洗剂及清洗工艺研究

Study on the neutral reagent and processing of cleaning the rust on the stone surface

本论文研究了石材表面锈黄斑的化学清洗方法,实验以草酸作为主清洗剂,同时添加水合肼等还原性的碱性物质作为助剂,调节pH值的同时增强了清洗效果。本实验实现了中性环境下清洗铁锈,选择的清洗剂配方的主剂与助剂都具有还原性,在清洗的有效性与安全性方面均取得了良好的效果。

This paper introduce the chemical cleaning method of the rust on the stone surface, including oxalic acid as the main with the strong reducibility hydrazine hydrate to adjust the pH value. Experiment results show that the presented cleaning agent acquires a great of achievements on the the safety and effectiveness.
