Jun 07, 2018· In this work, nano CL-20 and nano PETN were prepared using a mechanical milling method, in which a high-energy ball-mill was employed. The mill (a Retsch PM400) was designed and fabricated in Germany. The materials, such as 200 g balls, 20 g raw CL-20 (or raw PETN), 50 mL water, and 50 mL EtOH, were added into a ceramic jar.
milling is carried out to get an average particle size of 100nm or less. Mechanical milling is one of the most preferred and earliest technique to produce metallic microcrystalline powder. People claims to get a nanoparticle of very small size of up to 30nm particle size by using media milling of very small size of 200 micro meter.
Nanofabrication Process. Nanofabrication utilizing the principle of electrochemical dissolution or deposition is emerging as one of the efficient alternatives where bottom-up and top-down approach can effectively be synthesized to achieve more precise and cost-effective nanocomponents for nanotechnology applications.
May 16, 2006· The milling is carried out at room temperature for up to 150 hours. Following milling, the powder is annealed under an inert gas flow at temperatures of 1400°C for six hours. The mechanism of this process is not known, but it is thought that the ball milling process forms nanotube nuclei, and the annealing process activates nanotube growth.
Machinery FMEA is a methodical approach used for identifying risks associated with machinery and equipment failure.
