To stay away from noise, all we can do is sound insulation and silencing. Although there are many sound insulation cotton materials, such as glass wool, rock wool, sponge, polystyrene perlite and so on. They can solve the problem of sound insulation in our space, but they have hidden dangers in our lives, such as glass wool and rock wool, which can cause itchy skin and respiratory allergies. Sponge is a flammable product, which will produce toxic gas when burned.
At present, there are many common polyester fiber sound-absorbing cotton on the market, which are favored by users because of their excellent sound-absorbing effect and safety performance. However, due to the limitation of traditional manufacturing technology, they can only absorb the sound of a specific frequency, and the absorption of other frequencies such as low frequency is very limited. In order to solve this problem, our company introduced a new production method from the United States, selected 100% imported polyester fiber, adopted layered lamination, and strictly controlled the lamination pressure, so as to generate Panhoo graded sound-absorbing cotton from soft to hard layers, which has a good absorption effect on various frequencies of noise. It completely solves the limitation that ordinary polyester fiber sound-absorbing cotton can only eliminate medium and high-frequency sounds such as sound, and realizes good absorption of low-frequency sounds generated by electrical appliances, ground wall vibration, slippers mopping the floor, etc. Therefore, the Panhoo gradient sound-absorbing cotton we provide is not only a safe sound-absorbing cotton, but also an efficient sound-absorbing cotton. It is widely used for sound insulation and silencing of partitions, ceilings, floors and mechanical equipment. Its excellent performance is beyond the reach of other sound insulation and sound absorption materials. The safety is high, and the environmental protection detection performance reaches the national E 1 level. It is an efficient sound absorption and sound insulation material which is closest to nature, harmless to human body and pollution-free to the environment. In the production process, no glue is used, and the melting point characteristics are fully utilized to control the temperature for molding, so the product does not contain formaldehyde. After long-term experiments and practice, it has no allergic phenomenon to human skin. Its fire protection grade is national B 1 grade, which is not easy to burn and can be used in any place indoors. Its acoustic performance has been tested by the national authoritative department, and it has excellent performance in acoustic materials. Its raw material is flexible fiber, which will not be weathered and pulverized, and its acoustic performance will never decay. It is your first choice for sound absorption, sound insulation and silencing.
