硅藻泥专用纳米氧化锌

传统的有机紫外吸收剂容易降解以及具有迁移性，不能提供长期有效的抗紫外效果。纳米氧化钛和纳米氧化锌等无机紫外吸收剂，具有更强更持久的紫外线防护功能，因此广泛应用于工业中。 氧化钛具有光催化性能，在作为紫外吸收剂使用时必须经过表面处理。纳米氧化锌一般情况下不具有光催化性，并且具有较低的折射指数，透明性和抗紫外能力都非常优越，是一种理想的紫外吸收剂。 

 Conventional organic UV absorbers are prone to degradation and do not provide long-term protection. Inorganic UV absorbers have excellent long-term efficiency and TiO2 as well as ZnO are used in various industries. TiO2 requires special surface treatments to mask its inherent photoactivity. Zinc oxide exhibit no photoactivity, and their lower refractive index result in less impact on transparency. Nano-sized zinc oxide particles are therefore ideal UV absorbers.
