玻璃棉属于玻璃纤维中的一个类别，是一种人造无机纤维。采用石英砂、石灰石、白云石等天然矿石为主要原料，配合一些纯碱、硼砂等化工原料熔成玻璃。在融化状态下，借助外力吹制式甩成絮状细纤维，纤维和纤维之间为立体交叉，互相缠绕在一起，呈现出许多细小的间隙。这种间隙可看作孔隙。因此玻璃棉可视为多孔材料，具有良好的绝热、吸声性能。

Glass wool belongs to a category of glass fibers and is a type of artificial inorganic fiber. Natural ores such as quartz sand, limestone, and dolomite are used as the main raw materials, combined with some chemical raw materials such as soda ash and borax to melt into glass. In the melting state, with the help of external force blowing, it is thrown into flocculent fine fibers, and the fibers intersect in a three-dimensional manner, intertwined with each other, presenting many small gaps. This gap can be regarded as a pore. Therefore, glass wool can be regarded as a porous material with good insulation and sound absorption properties.

详细介绍

Detailed introduction

离心玻璃棉属于多孔吸声材料，具有良好的吸声性能。离心玻璃棉能够吸声的原因不是由于表面粗糙，而是因为具有大量的内外连通的微小孔隙和孔洞。当声波入射到离心玻璃棉上时，声波能顺着孔隙进入材料内部，引起空隙中空气分子的振动。由于空气的粘滞阻力和空气分子与孔隙壁的摩擦，声能转化为热能而损耗。

Centrifugal glass wool belongs to porous sound-absorbing materials and has good sound absorption performance. The reason why centrifugal glass wool can absorb sound is not because of its rough surface, but because it has a large number of small pores and pores connected inside and outside. When sound waves are incident on centrifugal glass wool, they can enter the interior of the material along the pores, causing vibrations of air molecules in the pores. Due to the viscous resistance of air and the friction between air molecules and pore walls, sound energy is converted into heat energy and lost.

吸声性能

Sound absorption performance

离心玻璃棉对声音中高频有较好的吸声性能。影响离心玻璃棉吸声性能的主要因素是厚度、密度和空气流阻等。密度是每立方米材料的重量。空气流阻是单位厚度时材料两侧空气气压和空气流速之比。空气流阻是影响离心玻璃棉吸声性能重要的因素。流阻太小，说明材料稀疏，空气振动容易穿过，吸声性能下降；流阻太大，说明材料密实，空气振动难于传入，吸声性能亦下降。对于离心玻璃棉来讲，吸声性能存在佳流阻。

Centrifugal glass wool has good sound absorption performance for medium to high frequencies of sound. The main factors affecting the sound absorption performance of centrifugal glass wool are thickness, density, and air flow resistance. Density is the weight of each cubic meter of material. Air flow resistance is the ratio of air pressure and air flow velocity on both sides of a material per unit thickness. Air flow resistance is an important factor affecting the sound absorption performance of centrifugal glass wool. If the flow resistance is too small, it indicates that the material is sparse, air vibration is easy to pass through, and the sound absorption performance is reduced; If the flow resistance is too high, it indicates that the material is dense, making it difficult for air vibration to be transmitted, and the sound absorption performance is also reduced. For centrifugal glass wool, there is a good flow resistance in terms of sound absorption performance.

在实际工程中，测定空气流阻比较困难，但可以通过厚度和容重粗略估计和控制。

In practical engineering, measuring air flow resistance is quite difficult, but it can be roughly estimated and controlled through thickness and bulk density.

1、随着厚度增加，中低频吸声系数显著地增加，但高频变化不大（高频吸收总是较大的）。

1. As the thickness increases, the sound absorption coefficient at medium and low frequencies significantly increases, but there is not much change at high frequencies (high frequency absorption is always large).

2、厚度不变，容重增加，中低频吸声系数亦增加；但当容重增加到一定程度时，材料变得密实，流阻大于佳流阻，吸声系数反而下降。对于厚度超过5cm的容重为16Kg/m3的离心玻璃棉，低频125Hz约为0.2，中高频（>500Hz）的吸声系数已经接近于1了。当厚度由5cm继续增大时，低频的吸声系数逐渐提高，当厚度大于1m以上时，低频125Hz的吸声系数也将接近于1。当厚度不变，容重增大时，离心玻璃棉的低频吸声系数也将不断提高，当容重接近110kg/m3时吸声性能达到大值，50mm厚、频率125Hz处接近0.6-0.7。容重超过120kg/m3时，吸声性能反而下降，是因为材料变得致密，中高频吸声性能受到很大影响，当容重超过300kg/m3时，吸声性能减小很多。建筑声学中常用的吸声玻璃棉的厚度有2.5cm、5cm、10cm，容重有16、24、32、48、80、96、112kg/m3。通常使用5cm厚，12-48kg/m3的离心玻璃棉。

2. The thickness remains unchanged, the bulk density increases, and the sound absorption coefficient at medium and low frequencies also increases; But when the bulk density increases to a certain extent, the material becomes dense, the flow resistance is greater than the optimal flow resistance, and the sound absorption coefficient actually decreases. For centrifugal glass wool with a bulk density of 16Kg/m3 and a thickness exceeding 5cm, the low-frequency 125Hz is about 0.2, and the sound absorption coefficient at medium and high frequencies (>500Hz) is close to 1. As the thickness continues to increase from 5cm, the low-frequency sound absorption coefficient gradually increases. When the thickness is greater than 1m, the low-frequency sound absorption coefficient at 125Hz will also approach 1. When the thickness remains unchanged and the bulk density increases, the low-frequency sound absorption coefficient of centrifugal glass wool will also continue to increase. When the bulk density approaches 110kg/m3, the sound absorption performance reaches its maximum value, and at a frequency of 125Hz and a thickness of 50mm, it approaches 0.6-0.7. When the bulk density exceeds 120kg/m3, the sound absorption performance actually decreases because the material becomes dense, and the medium and high frequency sound absorption performance is greatly affected. When the bulk density exceeds 300kg/m3, the sound absorption performance decreases significantly. The commonly used sound-absorbing glass wool in architectural acoustics has thicknesses of 2.5cm, 5cm, and 10cm, and unit weights of 16, 24, 32, 48, 80, 96, and 112kg/m3. Typically, 5cm thick, 12-48kg/m3 centrifugal glass wool is used.

离心玻璃棉的吸声性能还与安装条件有着密切的关系。当玻璃棉板背后有空气层时，与相同厚度无空气层的玻璃棉板吸声效果类似。尤其是中低频吸声性能比材料实贴在硬底面上会有较大提高，吸声系数将随空气层的厚度增加而增加，但增加到一定值后效果就不明显了。

The sound absorption performance of centrifugal glass wool is also closely related to installation conditions. When there is an air layer behind the glass wool board, the sound absorption effect is similar to that of glass wool boards with the same thickness but no air layer. Especially, the sound absorption performance at medium and low frequencies will be significantly improved compared to when the material is firmly attached to a hard substrate. The sound absorption coefficient will increase with the thickness of the air layer, but the effect will not be significant when it reaches a certain value.

叠加使用

Overlay usage

使用不同容重的玻璃棉叠和在一起，形成容重逐渐增大的形式，可以获得更大的吸声效果。例如将一层2.5cm厚24kg/m3的棉板与一层2.5cm厚32kg/m3的棉板叠和在一起的吸声效果要好于一层5cm厚32kg/m3的棉板。将24kg/m3的玻璃棉板制成1m长的断面为三角型的尖劈，材料面密度逐渐增大，平均吸声系数可接近于1。

Using glass wool with different bulk densities stacked together to form a gradually increasing bulk density can achieve greater sound absorption effect. For example, stacking a layer of 2.5cm thick 24kg/m3 cotton board with a layer of 2.5cm thick 32kg/m3 cotton board together has a better sound absorption effect than a layer of 5cm thick 32kg/m3 cotton board. A 24kg/m3 glass wool board is made into a 1m long triangular wedge with a gradually increasing material density, and the average sound absorption coefficient can approach 1.
