NIRVANA - Near Infra-Red photoinitiated curing of industrial wood coatings and varnishes

与传统的紫外线汞弧灯（减少约60%）和传统的燃气干燥系统（减少约90%）相比，利用发光二极管（LED）的辐射固化为工业木材涂料应用提供了大量的节能。然而，由于以下原因，辐射固化应用的增长受到限制：UV在着色涂层中的深度渗透差;表面涂层性能差（由于氧抑制）以及缺乏优化的涂料配方。NIRVANA将通过以下方式为这些挑战提供3种新颖的解决方案：1.在880-1000 nm透射窗口内开发创新的近红外（NIR）光引发剂，在此窗口内光通常不会被吸收或散射。开发新型有机-无机杂化纳米材料，提高表面交联密度和硬度，降低氧阻.创建100%固体丙烯酸酯基树脂木器涂料配方，可使用节能NIR LED照射固化

Radiation Curing utilising Light Emitting Diodes (LED) offers substantial energy savings for industrial wood coating applications compared to conventional UV mercury arc lamps (~60% less) and traditional gas fired drying systems (~90% less). However, the growth of Radiation Curing applications has been limited due to: Poor depth penetration of UV in pigmented coatings; Poor surface coating properties (due to oxygen inhibition) and the absence of optimised coating formulations. NIRVANA will deliver 3 novel solutions to these challenges by:1. Developing an innovative near-infra red (NIR) photoinitiator within the 880-1000 nm transmission window where light is not typically absorbed or scattered.2. Developing novel hybrid organic-inorganic nano-materials to increase surface cross linking density and hardness and reduce oxygen inhibition.3. Creating formulations of 100% solids acrylate based resin wood coatings that can be cured using energy efficient NIR LED irradiation
