The sound-absorbing cotton in the light steel keel partition wall is made of rock wool, glass wool, or what kind of cotton? Is rock wool a sound-absorbing cotton?

What is placed inside the light steel keel partition wall is usually glass wool, whose main function is sound insulation; rock wool can not only insulate sound, but also has heat insulation properties and can be used as thermal insulation material. Both materials have sound-absorbing properties.

Glass wool belongs to a category of glass fiber and is a man-made inorganic fiber. Glass wool is a material made by fiberizing molten glass to form a cotton-like material. The chemical composition is glass and it is an inorganic fiber. It has good molding, low volume density, high thermal conductivity, thermal insulation, good sound absorption performance, and corrosion resistance. , chemical properties are stable.

Glass wool is made of centrifugal glass wool felt. It uses Owens Corning (OC)’s unique patented centrifugal technology to fiberize molten glass and add an environmentally friendly formula binder based on thermosetting resin. The processed product is an elastic felt-like body made of glass fiber with a diameter of only a few microns, and different moisture-proof veneers can be selected for online compounding according to usage requirements. It has a large number of tiny air pores, which enable it to play the roles of thermal insulation, sound absorption and noise reduction, and safety protection. It is the best material for thermal insulation, sound absorption and noise reduction of steel structure buildings.

Glass wool belongs to a category of glass fiber and is a man-made inorganic fiber. Using quartz sand, limestone, dolomite and other natural ores as the main raw materials, combined with some soda ash, borax and other chemical raw materials, it is melted into glass. In the melted state, it is blown into floc-like thin fibers with the help of external force. The fibers are three-dimensionally crossed and entangled with each other, showing many small gaps. This gap can be regarded as a pore. Therefore, glass wool can be regarded as a porous material with good thermal insulation and sound absorption properties.
