    In aerospace engineering, the high pressure shaft in jet engines, for instance, is responsible for driving the compressor stage, which forces air into the engine at supersonic speedshigh pressure shaft. Any failure in this component could lead to catastrophic consequences, emphasizing the need for stringent quality control and regular maintenance.

    3, mineral fiber ceiling as a Sound Absorption Ceilling Board with mineral fiber as the main raw material, and mineral fiber micro-pores developed, reduce sound wave reflection, eliminate echo, and isolate the noise transmitted by the floor. The sound wave hits the surface of the material, and is partially reflected back, partially absorbed by the plate, and a part passes through the plate into the rear cavity, which greatly reduces the reflected sound, effectively controls and adjusts the indoor reverberation time, and reduces noise.
