In a significant advancement for the aviation repair industry, researchers from Lingyun Technology Group Co., Ltd. and the Wuhan Institute of Technology have developed a novel foam adhesive remover designed specifically for aircraft applications. This innovation addresses a critical challenge in the maintenance of aircraft components, such as wing endplates and spoilers, where traditional methods often risk damaging the underlying aluminum alloy.
The study, published in ‘Cailiao Baohu’ (Materials Protection), focuses on the efficient removal of cured foam adhesives without compromising the structural integrity of the aircraft materials. “Our goal was to create a remover that not only works effectively but also minimizes environmental impact and protects the substrate,” said lead author Ding Meng. The research team employed infrared spectroscopy and thermogravimetric analysis to understand the properties of foam adhesives, leading them to identify dichloromethane as the primary solvent for their remover.
To further enhance the remover’s performance, the researchers incorporated TiO2-modified SiO2 nanocapsules into the formulation. These nanocapsules serve dual functions: they act as adsorbents and slow-release agents, which help reduce volatile organic compound (VOC) emissions and extend the operational time of the remover. “By utilizing mechanisms like physical adsorption and slow release, we can provide a more efficient and safer solution for aircraft maintenance,” noted Zhu Hao, another key contributor to the study.
The formulation also includes paraffin and polyethylene sheets as surface barriers, along with Halox630 corrosion inhibitor, which significantly mitigates the risk of corrosion and the volatilization of the remover. This combination not only enhances the effectiveness of the adhesive removal process but also ensures that the aircraft remains protected during maintenance.
The implications of this research extend beyond aviation. In the construction sector, where adhesive applications are prevalent, the development of such specialized removers could streamline maintenance processes, reduce downtime, and lower overall costs. As the industry increasingly prioritizes sustainability and safety, innovations like this foam adhesive remover are likely to shape future practices in material handling and repair.
The research underscores a growing trend in the construction and aviation industries toward more environmentally friendly and effective maintenance solutions. With the potential for widespread application, this foam adhesive remover could revolutionize how aircraft and other structures are repaired, ensuring longevity and safety without compromising material integrity.
