Saint Gobain Isovel ultra-fine glass wool board

The smoke control glass wool produced by our company is specifically developed for use in smoke control equipment. Compared with ordinary glass wool, smoke control glass wool, Is it covered with aluminum foil veneer orffrComposite materials with veneers have better fire and fire resistance properties. The combination of smoke proof glass wool and smoke proof equipment can achieve a fire resistance limit of up to1.5hThe acceptance results are higher than the national fire prevention standards. Welcome to our company for negotiations. We sincerely look forward to a win-win cooperation with you.

Performance characteristics of smoke proof glass wool board:

1Smoke prevention and exhaust insulation environmentally friendly glass wool is wrapped around the metal smoke prevention and exhaust pipe, which can isolate the heat of fire smoke, prevent it from being transmitted through the pipe wall, and help the smoke prevention and exhaust pipe achieve the required fire resistance and insulation effect.

2Smoke proof glass wool is non corrosive to pipelines and will not cause metal corrosion to ventilation ducts.

3The smoke proof glass wool board also has hydrophobicity.

4Glass wool fibers do not contain asbestos.

5Smoke proof glass wool board belongs to fiber structure, which can reduce the noise of smoke exhaust pipes.

For centrifugal glass wool, there is flow resistance in the sound absorption function.

In the process of engineering, the atmospheric flow resistance is being measured for comparison, but the thickness and bulk density can be roughly and controlled.

1. As the thickness increases, the absorption coefficient of medium and low frequencies becomes significant, but there is little change in high frequencies (those with larger absorption).

2. Stable thickness, increased bulk density, and increased mid to low frequency sound absorption coefficient; But when the bulk density increases to a certain level, the material becomes dense and the flow resistance is greater thangeneralThe flow resistance and sound absorption coefficient actually decrease. Regarding Thickness ExceedingA 5cm centrifugal glass wool with a bulk density of 16Kg/m3 has a low frequency of approximately 0.2 at 125Hz, and a sound absorption coefficient of over 1 at mid to high frequencies (>500Hz). When 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 125Hz sound absorption coefficient will also approach 1. When the thickness is stable and the bulk density increases, the low-frequency sound absorption coefficient of centrifugal glass wool will also continue. When the bulk density approaches 110kg/m3, the maximum sound absorption function is achieved, and at a thickness of 50mm and a frequency of 125Hz, it approaches 0.6-0.7. When the bulk density exceeds 120kg/m3, the sound absorption function actually decreases due to becoming denser, which greatly affects the mid to high frequency sound absorption function. When the bulk density exceeds 300kg/m3, the sound absorption function decreases significantly. The commonly used sound-absorbing glass wool in acoustics has thicknesses of 2.5cm, 5cm, and 10cm, and bulk densities of 16, 24, 32, 48, 80, 96, and 112kg/m3. Normally 5cm thick, 12-48kg/m3 centrifugal glass wool.
