Enhancing Sealing Element Security: Quantum Dot Marking Solutions Of NBR And TPU Sealing Elements

Summary

In response to the escalating need for integrated product security amidst the rising challenge of counterfeiting, luminescent labels have emerged as crucial tools for safeguarding original products. Leveraging nanoparticles for marking activities not only enhances product safety but also mitigates operational costs while bolstering traceability and sustainability. This study focuses on integrating quantum dot (QD) marking solutions into NBR and TPU, widely utilized in sealing elements crucial for hydraulic and pneumatic systems.

Initially, the research delves into the optical properties of elastomer materials infused with various types of QDs. Mechanical property alterations and optical readings of marked elastomers post-abrasion and aging with different media are examined in the initial phase. Subsequently, the study elucidates the benefits of incorporating QD markers into elastomers, emphasizing traceability, product safety, and sustainability.

Employing specially designed sensors and embedded smart algorithms, quantum tags crafted from the optical properties of nanoparticles facilitate optical reading, conversion of readings into electronic signals, and signal processing for sample qualification and/or verification. Product verification entails comparing obtained signals with reference data, thereby ensuring authenticity.

By showcasing the efficacy of QD marking solutions on elastomers, this research underscores the potential for bolstering sealing element security, offering a promising avenue for combatting counterfeiting and enhancing product integrity in critical industrial systems.
