Ceramic fiber blankets are widely used in the construction industry because of their good insulation, sound absorption and heat insulation. Why is it so powerful? Below we analyze it from the aspects of its internal construction conditions.
The ceramic fiber blanket is used as a material for sound absorption and noise reduction because it has an air layer behind it or a surface with some decorative materials. In the range of the thickness of the air layer of 100-150 mm, the thicker the thickness of the air layer, the higher the sound absorption rate of the middle and low-range regions, such as air thickening to about 300 mm, and the effective sound absorption rate range is expanded to 100 Hz.
The internal fibers of the ceramic fiber blanket are fluffy and interlaced, and there are a lot of tiny pores. It is a typical porous sound absorbing material with excellent sound absorption and noise reduction characteristics.
The needle-punched blanket can be made into a wall, a ceiling, a sound absorbing body in a certain space, etc., and can absorb a large amount of sound energy in the room, and reduce the reverberation time to reduce indoor noise. Product use (action): wall sound absorption, wall sound insulation, wall insulation, wall insulation.
The ceramic fiber blanket is a kind of heat insulating material which uses a needle punching process to form a fiber-like heat insulating cotton into a blanket shape, and the appearance of the product can distinguish the advantages and disadvantages of the product, and whether the appearance thereof has impurities or stains, etc. , to test its tensile strength, a good quality acupuncture blanket has a certain degree of toughness,
If there is a phenomenon of falling objects during the process of pulling, it means that the quality is problematic, and the color of the needle-punched blanket product with yellowish color can be distinguished. The quality will be slightly worse; the quality is identified. The method is to measure the volume according to the test standard, such as the weight per cubic is about 100 kg.
