Why does white corundum have special function in sound insulation

The white corundum product itself is a comparative product, which can be used in various industries and fields for many purposes. Among these, we have not known before that the white corundum also has excellent sound insulation and attraction functions. Now let's focus on the function of white corundum.
The reason why white corundum products can have this special function is mainly because the product itself belongs to an inorganic silicate fiber, which makes the product porous. In addition, these pores on the surface of white corundum are connected with each other rather than closed static, so when sound waves pass by, part of the sound energy will be converted into heat energy and absorbed by the fiber.
Because of this, the application range of white corundum products has been expanded, and can be used in shopping malls, cinemas, subways, stations, airports, hotels and residential buildings. Moreover, due to the incombustibility of white corundum, it is also a good choice as materials for arson doors, vertical fire walls, packaging, decoration, etc.
