This waste reutilisation project develops a novel nanotechnology of coated fly ash particles to simulate titania as paint pigment/filler. The strategy uses a novel high-temperature injector fluidised bed reactor to make tunable coatings of graded SiO2/ZnO/TiO2 layers of increasing refractive index to enhance total internal reflection and scattering to increase whiteness and opacity; doping of the TiO2 neutralises colour and reduces paint chalking. These advanced nanoscale coated materials are a new direction for a long-term partnership between the CI and KIP in materials development. The laboratory- to pilot-scale manufacturing extension will enable high-volume use in paints generating significant economic and environmental outcomes.

该废物再利用项目开发了一种新型的包覆粉煤灰颗粒纳米技术，以模拟二氧化钛作为涂料颜料/填料。该策略使用一种新型的高温喷射流化床反应器，使梯度SiO2/ZnO/TiO 2层的可调涂层的折射率增加，以增强全内反射和散射，增加白度和不透明度;掺杂的TiO 2中和颜色，减少油漆粉化。这些先进的纳米涂层材料是CI和KIP在材料开发方面长期合作的新方向。从实验室到中试规模的生产扩展将使涂料的大量使用能够产生重大的经济和环境成果。
