纳米技术(nanotechnology)正式诞生于1990年,是用单个原子、分子制造物质的科学技术,研究结构尺寸在0.1至100纳米范围内材料的性质和应用。纳米技术在石材养护行业的应用还刚刚起步,具有广阔前景。1、采用纳米技术的石材表面防护剂具有良好的防水和防污效果。石材表面经处理后,防护剂渗透到石材微孔内部形 Nanotechnology (nanotechnology) was formally born in 1990, is the use of a single atom, molecule science and technology to study the structure of materials in the range of 0.1 to 100 nanometer properties and applications. The application of nanotechnology in the stone conservation industry has just started, with broad prospects. 1, using nanotechnology stone surface protective agent has good waterproof and anti-fouling effect. After treatment of the stone surface, the protective agent penetrates the internal shape of the stone micropore
