Glass wool board high-density fireproof and soundproofing cotton Guangzhou Kunai Building Materials was established in 2006. It specializes in various types of thermal insulation, sound-absorbing and soundproofing and other building decoration materials. The company has grown from a few members to a team of more than 100 people today. It relies on our understanding of Quality assurance and continuous improvement of services. Now our company has dozens of Taobao Tmall stores, Alibaba stores, and ordinary Taobao stores online, and offline branches in Guangzhou, Wuhan and Shijiazhuang to meet the purchasing needs of different customers and friends.
Glass wool board is a rectangular board with various bulk weights to choose from. Generally used as thermal insulation materials, they are basically centrifugal glass insulation boards. The average fiber diameter is about microns, which can meet the requirements of thermal insulation cost-effectively. According to the thermal insulation requirements, each specification is divided into two types: veneer and non-veneer. They are both lightweight, wear-resistant, and tough. They can be used on various irregular-shaped surfaces to effectively save energy, reduce heat loss, and reduce operating costs. Cost, correctly installed glass wool board can effectively reduce the transmission of sound waves.
Centrifugal glass wool can be made into wall panels, ceilings, space sound absorbers, etc. It can absorb a large amount of sound energy in the room, reduce reverberation time, and reduce indoor noise. Has good sound absorption properties.
Scope of application: thermal insulation, sound insulation and silencing of home walls, ceilings, sewer pipes, bathrooms, etc., factory building silencing and building silencing and insulation projects, generator set silencing, air conditioning, acoustic laboratory, music recording studio, speakers, Auditing rooms, studios, surveying and mapping rooms, rooms, star hotels and other industries and places.
Centrifugal glass wool has good sound absorption performance for medium and high frequencies. The main factors affecting the sound absorption performance of centrifugal glass wool are thickness, density and air flow resistance. Density is the weight of material per cubic meter. Air flow resistance is the ratio of air pressure and air flow velocity on both sides of the material per unit thickness. Air flow resistance is the most important factor affecting the sound absorption performance of centrifugal glass wool. The flow resistance is too small, indicating that the material is sparse, air vibrations can easily pass through, and the sound absorption performance is reduced. The flow resistance is too large, indicating that the material is dense, air vibrations are difficult to transmit, and the sound absorption performance is also reduced. For centrifugal glass wool, the sound absorption performance has the best flow resistance.
In actual engineering, it is difficult to measure air flow resistance, but it can be roughly estimated and controlled through thickness and bulk density.
As the thickness increases, the sound absorption coefficient at mid- and low-frequency increases significantly, but the high-frequency change does not change much (high-frequency absorption is always larger).
, the thickness remains unchanged, the bulk density increases, and the sound absorption coefficient of medium and low frequencies also increases. However, when the bulk density increases to a certain level, the material becomes dense, the flow resistance is greater than the optimal flow resistance, and the sound absorption coefficient decreases instead. For centrifugal glass wool with a thickness exceeding the bulk density of , the sound absorption coefficient of low frequency is about , and the sound absorption coefficient of medium and high frequency () is close to . When the thickness continues to increase, the low-frequency sound absorption coefficient gradually increases. When the thickness is greater than the above, the low-frequency sound absorption coefficient will also be close to.
