Technology of Surface Coating

Compare

Surface coating means a fluid, semifluid, or other material, with or without a suspension of finely divided coloring matter, that changes to a solid film when a thin layer is applied to a metal, wood, stone, paper, leather, cloth, plastic, or other surface.

Vibration of Structures

Compare

Structural vibration occurs when dynamic forces generated by compressors, pumps, and engines cause the deck beams to vibrate. This vibration leads to piping failures, poor equipment reliability, and safety concerns. The vibration is due to the structure being mechanically resonant.
