Jinqiao non-woven sound-absorbing cotton advantages and appl

Jinqiao non-woven sound-absorbing cotton is used in the following industries:

1. The light body wall partition used for light steel keel gypsum board structure replaces rock wool or glass wool;

2. Replace the sponge and other sound-absorbing soft bags in entertainment venues such as KTV, theaters, dance halls, etc.;
3. It is used for acoustic decoration in recording studios, listening rooms, interrogation rooms and other places. Advantages of Jinqiao non-woven sound-absorbing cotton:
1. 100% environmentally friendly products, 100% recyclable.
2. Sturdy, easy to use, odorless, waterproof, moisture-proof, easy to process, can be made into various shapes according to different needs, and has a long service life.
3. Can resist the corrosion of various microorganisms, fungi, acids, salts and hydrocarbons.
4. No additives are added in the production process.
At present, there are many ordinary polyester fiber sound-absorbing cotton on the market, which is favored by users because of its excellent sound-absorbing effect and safety performance. Due to the limitation of the traditional production process, it can only have a good absorption effect on the sound of a specific frequency, but the sound absorption of other frequencies such as low frequency is very limited. In order to solve this problem, my country has introduced a new production method, using 100% imported polyester fiber, using lamination, and strictly controlling the lamination pressure, so as to produce Panhoo gradient sound-absorbing cotton from soft to hard between layers. The noise of this frequency has a good absorption effect. It completely solves the limitation that ordinary polyester fiber sound-absorbing cotton can only eliminate medium and high-frequency sounds such as speech, and achieves good absorption of low-frequency sounds such as electrical appliances, floor and wall vibration, and slippers mopping the floor. Therefore, Panhoo gradient sound-absorbing cotton is not only a safe sound-absorbing cotton, but also an efficient sound-absorbing cotton. Widely used in the sound insulation and silencing of partition walls, ceilings, floors, and mechanical equipment. Its excellent performance is unmatched by other sound insulation materials. It has high safety, and its environmental protection testing performance has reached the national E1 level. No glue is used in the production process, making full use of its own melting point characteristics, controlling the temperature to form, and the product does not contain formaldehyde. After long-term experiments and practice, it has been proved that there is no allergic phenomenon to human skin. Its fire rating is the national B1 level, and it is a combustible product that can be used in any indoor place. Its acoustic performance is tested by the national authoritative department, and it has excellent performance in acoustic materials. The raw material is flexible fiber, which is not weathered or pulverized, and its acoustic performance will not decay forever.
The difference between glass fiber sound-absorbing cotton and polyester fiber sound-absorbing cotton.
The two products are different, the sound absorption effect is basically the same, but the glass fiber is not environmentally friendly, and the construction is inconvenient, we all know itching, polyester fiber is a little flame retardant, fire, prefers to burn than wood, if you go out in the yard, you can run out , if you don't use the basement karaoke, the burning will suffocate, what's your opinion, polyester fiber is much cheaper about 65-105 fiberglass.
Polyester fiber sound-absorbing cotton fiber is a non-woven material composed of ultra-fine fibers with a diameter of 1-4 microns and short fibers with a diameter of 20-30 microns. Blow-melt processing allows finer fibers to be used to create lightweight, bulky, high-quality products.
