Abstract:

Nanobelt Ca0.68Si9Al3(ON)16 : Eu2+ luminescence fibers for wear detection of disc cutter were prepared by a simple process electrospinning combined with gas-reduction method, and then characterized by FE-SEM, XRD, PL, and universal material testing machine. The obtained sample keeps fiber film state in micro and macroscopic level with a certain mechanical strength, temperature, waterproof and chemical stability. XRD patterns of the sample doped with Eu2+ 0.1 nitrided at 1500℃ for 4 h were crystallized well and assigned to Ca0.68Si9Al3(ON)16 in JCPDF card. The fiber film can be effectively excited by blue light, showing a broad emission spectrum in the range from 400 to 700 nm. The luminescent fiber film can be practically assembled onto disc cutters for detection. The wear degree of each cutter can be real-timely monitored in the main control room, which reduces the artificial detection at high pressure and high risk geological section, the investment cost, and the occupational risk of operators.

Key words: electrospinning, nanobelt fiber, luminescence fiber, disc cutter, wear detection
