Why does white corundum have the special function of sound insulation

The white corundum product itself is a comparative product, which can be applied to various industries for many purposes, among which, there is one thing that we have not known before, that is, white corundum also has excellent sound insulation and attractive functions. Then let's focus on the function of white corundum in this respect.
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 to each other without being closed and static, so that when sound waves pass by, part of the sound energy will be converted into heat energy and absorbed by the fiber.
It is because of this that the application of white corundum products has expanded a circle, and can be used in shopping malls, movie theaters, subways, stations, airports, hotels and homes. And because of the non-combustible nature of white corundum, as an arson door, arson wall, packaging, decoration and other materials is also a good choice.
