Introduction to the sound insulation effect of insulation factory material rock wool board? There are many types of insulation materials, among which rock wool board is a popular external insulation material. In addition to its thermal insulation effect, rock wool board also has environmental protection and sound insulation effects. Today, let's talk about the sound insulation effect of rock wool board? Rock wool board is a crucial and efficient sound insulation and noise reduction material in temperature control factories. Its sound insulation effect mainly comes from its unique porous fiber structure and high-density characteristics, which can effectively improve the acoustic environment inside the factory. What is the sound insulation principle of rock wool board?
1. Porous sound-absorbing structure
The interior of the rock wool board is composed of countless interlocking mineral fibers, with a porosity of over 90%. When sound waves enter these tiny pores, they generate friction with fibers, converting sound energy into heat energy and consuming it, thereby reducing sound reflection. They are particularly good at absorbing mid to high frequency noise (such as human voices and machine operation sounds). 2. High density sound barrier
According to the law of quality, the higher the density of a material, the stronger its ability to block sound propagation. High density rock wool board (usually with a density greater than 100kg/m ³) acts as a thick barrier, effectively blocking external or internal noise from entering or exiting. 3. Elastic damping vibration reduction
The flexible fiber structure of rock wool board can effectively reduce the transmission of solid vibration, which is very effective in reducing the structural noise (impact sound) generated by the propagation of equipment vibration through walls or floors.
