It can be used both handheld for precision work or mounted on a stand for more controlled, larger-scale operations It can be used both handheld for precision work or mounted on a stand for more controlled, larger-scale operationsrotary jack hammer. However, due to its weight and intense vibration, operating a rotary jack hammer requires strength, skill, and safety precautions. Users should wear protective gear, including earplugs, safety glasses, and heavy-duty gloves, and ensure the tool is well-maintained to prevent accidents.Due to the hard carbon nanofibers and abundant welded joints among the nanofibers, the hard carbon aerogels display robust and stable mechanical performances, including super-elasticity, high strength, extremely fast recovery speed (860 mm s-1) and low energy loss coefficient (<0.16). After tested under 50 % strain for 104 cycles, the carbon aerogel shows only 2 % plastic deformation, and retained 93 % original stress.
Given their excellent radiation shielding properties, they are employed in the construction of containment vessels, piping systems, and radiation shields Given their excellent radiation shielding properties, they are employed in the construction of containment vessels, piping systems, and radiation shieldsfrp products for thermal and nuclear power. These materials help to mitigate radiation exposure to personnel and protect the integrity of the reactor infrastructure. Moreover, the non-corrosive nature of FRP ensures long-term reliability, reducing the risk of leaks or structural failures.
