It is no stranger to mention noise. Noise affects our work efficiency, sleep, hearing and health at all times. And how many of us have thought about eliminating it? Even if you think of it, how many people know how to eliminate it? In order to solve this problem, China introduced a new production method, selected 100% imported polyester fiber, laminated pressure, strict control of the pressure of lamination, resulting in a layer of soft-to-hard Panoil gradient sound-absorbing cotton, which It has a good absorption effect for various frequencies of noise. In addition, there is another kind of sound insulation cotton. Both of them are very good at eliminating noise. So what is the difference between sound-absorbing cotton and sound-absorbing cotton ? How can we distinguish between us? Don't worry, if you have this need, you may wish to follow me to learn about the difference between sound-absorbing cotton and sound-absorbing cotton .
Sound-absorbing cotton effect
1. Instead of rock wool or glass wool, lightweight wall partitions for light steel joist gypsum board structures
2, instead of sponges and other soft sound-absorbing kits for KTV, theaters, discos and other entertainment venues
3. Acoustic decoration and decoration for recording studios, listening rooms, interrogation rooms and other places
Sound-absorbing cotton advantage
1.100% Environmental Products, 100% Recyclable
2. Strong, easy to use and odorless, waterproof, moisture-proof, breathable, easy to process, can be made into various shapes according to different needs, long service life
3. Will not rot, resisting the corrosion of various microorganisms, fungi, acids, salts and hydrocarbons
4. Do not add any additives or adhesives during the production process.

Sound-absorbing cotton installation
A sound-absorbing cotton installation, pay attention to the selection board, row board before construction, to avoid the slight color difference
Polyester fiber acoustic panels, based on 100% polyester fiber, are formed by hot pressing. Due to the different color numbers of colored yarns, they are easy to produce small color differences under the effect of light; therefore, the same lot number should be used when purchasing goods. Polyester fiber acoustic panels, before the construction of polyester fiber acoustic panels for plate, adjust the color difference and then install in accordance with the order of adjustment (the best carrier gloves to avoid contamination) construction.
Sound-absorbing cotton installation Second, the cutting board surface should use steel ruler
During the construction, it is necessary to cut the polyester fiber sound-absorbing board. When cutting, it is recommended to use steel ruler or alloy square steel as the ruler (do not use wood or soft material as the ruler) to avoid cutting lines that are not straight and cause the joint gap to cross. Large or twisted to make the splicing gap relatively reduced, when cutting the blade can be properly tilted inward 0.5 ~ 1mm, so that the interface surface to form a slope, the construction is easy to face the panel to reduce the gap.
The sound-absorbing cotton is installed with a blade for cutting, cutting or inverting. It is recommended to use imported blades.
Because of the quality of the domestic art blade steel, the blade is not sharp enough and has a short service life. It is easy to produce burrs and rough edges when cutting or inverting edges, especially when the edge is inverted, so it is better to use high-quality imported blades.
Reverse edge can use this product special edge planing.
Sound-absorbing cotton installation four, base surface treatment
When the base surface is required to be flat, when the cement base surface is directly pasted, the base surface must be leveled and then affixed with a polyester fiber acoustical panel; if there is a base layer with a back cavity, the splint splicing gap should be glued first. Stick (or adhesive tape) paste. In the case of a perforated plate base layer, the holes should be treated before the perforated plate is installed (interior films, etc. may be used). In order to avoid air flow under the grass roots.
Sound-absorbing cotton installation five, paste glue selection
First consider using glue that meets the national environmental protection requirements.
Different types of adhesives can be used depending on the adhesive base.
1. Cement or wood base: Select chloroprene rubber-free phenolic or white latex.
2, the gypsum board base: on the premise of not easy to damp, you can use white latex or cellulose as raw material wallpaper glue (brush adhesive paste should be immediately fixed with studs to avoid glue is not dry, board surface Mobile), in the premise of easy or possible moisture, optional adhesive.
Polyester fiber acoustic panels, is a porous sheet, easy to absorb glue, block holes, it is recommended that the construction can be single-sided brushing (only on the wall brush glue, brush glue slightly thicker than normal). At the same time can also be accompanied by studs reinforcement.
Sound-absorbing cotton installation six, Yin, Yang angle processing
Polyester fiber sound-absorbing panels can be used for yin and yang treatment. The method is the same as that of aluminum-plastic composite panels.
The difference between sound-absorbing cotton and sound-absorbing cotton
Sound-absorbing cotton is mostly made of fiber material, open-pore structure, more fluffy, the main role is to absorb noise, so that the noise is attenuated; soundproof cotton is mostly rubber material, closed-cell structure, more solid porcelain, the main role is to block the noise. Sound-absorbing cotton and sound-absorbing cotton are indispensable in noise reduction construction. In the case of relatively high noise reduction requirements, it is necessary to use both together. The noise can be attenuated to very small after being subjected to multiple filtration in the order of sound insulation, sound absorption and sound insulation.
Editor's summary: The above is the introduction of the relevant knowledge about the difference between sound-absorbing cotton and sound-absorbing cotton. I hope to help friends who have this need!
