Sound absorption and heat insulation of glass wool

Because the sleeve of this material has the characteristics of waterproof, anti-corrosion, no mold, and no insects, it can effectively prevent condensation and prevent pipeline freezing, and is widely used for the insulation of civil buildings, heating pipes, air conditioners and refrigeration equipment. Insulation, energy saving effect can be increased by 15-30%.
Shenzhou glass wool has excellent characteristics such as fireproofing, heat preservation and easy cutting. It is one of the most commonly used materials for building sound absorption. However, since the surface of the centrifugal glass wool is not decorative, and there is a fiber sprinkling, it is necessary to make various sound absorbing members concealed.
1. The most commonly used and lowest cost construction is a paper perforated gypsum board ceiling or a wall filled with centrifugal glass wool. Helmholtz resonance absorption can be formed when there is an air layer between the paper perforated gypsum board and the wall or ceiling. Generally, the air layer is 5cm, 10cm, 20cm, 40cm, and the air layer of the ceiling may be larger. When the centrifugal glass wool is filled in the cavity, the efficiency of the resonance sound absorption is also greatly improved due to the sound absorption of the glass wool itself, and the sound absorption coefficient is greatly improved.
2. The glass wool board can be made into a sound absorbing ceiling board or a sound absorbing wall board after being processed. Generally, 80-120kg/m3 glass wool board is cured by glue curing, and the fire-proof sound-permeable fabric is formed to form a sound-absorbing wall board which is both beautiful and convenient to install.
3. In the large space such as stadiums and workshops, in order to absorb noise and reduce noise, a sound absorbing body using centrifugal glass wool as the main sound absorbing material is often used. The sound absorbing body can be made into a plate shape, a column shape, a cone or other shaped body as required. The sound absorbing body is filled with centrifugal glass wool, and the surface is wrapped with a sound-permeable surface layer. Since the sound absorbing body has a plurality of surface sound absorbing sounds, the sound absorbing efficiency is high.
4. In the road sound insulation barrier, in order to prevent noise reflection, it is necessary to take sound absorption measures on the side facing the vehicle, and often also use centrifugal glass wool as a filling material and a barrier plate whose surface layer is a perforated metal plate. In order to prevent the glass wool from absorbing water and moisture outside, it is sometimes wrapped with pvc or plastic film.
The application of glass wool has become more and more extensive, and Shenzhou glass wool can be said to be the top brand enterprise in the building materials industry. Many glass wool manufacturers will produce and sell under the banner of Shenzhou. We are in Shenzhou, Hebei.
