Production Process Of Sound Insulation Felt

 

We opened Google and saw the “Application Field of Sound Insulation Mat” section of the sound insulation mat entry. The first two items are as follows:

 

1. Civilian residential application: (wall sound insulation, ceiling sound insulation, pipe sound insulation) Car noise on the road, walking and talking upstairs, talking next door, and TV sound will all be transmitted to the room through the wall, affecting your rest. Combining sound insulation mat with gypsum board to make wall panels or ceilings can effectively isolate the invasion of these noises. Laying it on the floor can effectively suppress the impact sound generated when objects come into contact with the ground, improving your rest quality.

 

2. Application in entertainment venues: (KTV rooms, partitions, ceilings, floors, etc.) In bars, low-frequency vibration sounds have very strong penetration and long reverberation time, affecting the lives of residents near entertainment venues. Therefore, residents’ complaints will make entertainment venues unable to operate normally, which will have a huge impact on the business of merchants. Sound insulation mat combined with professional sound insulation technology can allow residents to return to a quiet life again.

 

The environmentally friendly sound insulation mat produced by our company can be made into specifications within the range of 300g/m2~5000g/m2, and the thickness can be made into the range of 3mm~10cm. Our company’s environmentally friendly sound insulation mat first sets the feeding ratio according to the process requirements, pre-loosens, and evenly mixes the loosened raw materials. Then, the loosened materials are finely loosened, automatically loaded into the air-laid netting bin, set the netting, and then go through the oven for finalization. The products are cut according to the process requirements, packaged, stored, and shipped.

 

Our company has imported production equipment, and the environmentally friendly sound insulation mat produced has the following advantages:

 

(1) Lightweight and ultra-thin material

(2) Soft and high tensile strength

(3) Environmentally friendly, no pollution to the environment

(4) Suppresses the propagation of medium and low frequency sound waves; excellent flame retardant performance

(5) Easy to construct.

 

The web laying process of sound insulation mat is divided into web forming process and web fixing process.

 

The web forming process is mainly divided into carding web forming, airflow web forming, and meltblowing.

 

Carding web forming is also called mechanical web forming. The raw materials are loosened and mixed and sent to the carding machine, and then the doffer of the carding machine condenses and outputs to form a fiber web. This web forming method and equipment were more popular in the early non-woven fabric production, and the equipment was mainly various cotton and wool carding machines. The products produced by this method have large differences in longitudinal and transverse strength of the fiber web because the fibers are arranged in the direction of machine output. When carding web, the original fibers are limited, and the strength and elongation of the original fibers will be destroyed during carding.

 

The process of meltblowing: polymer feeding—melt extrusion—fiber formation—fiber cooling—web—reinforcement into cloth. The meltblowing process is demanding on raw materials. The raw materials must be able to reach a molten state. The production energy consumption is relatively large, and environmental protection will cause pollution. At the same time, the raw materials will cause unnecessary problems such as aging in a molten state.

 

The sound insulation mat produced by our company belongs to the air-laid process. Air-laid refers to the fiber being opened, cleaned, and mixed, and then fed into the main combing mechanism. After further combing, it is in a single fiber state. Under the combined action of the eccentricity generated by the high-speed rotation of the cylinder and the airflow, the fiber falls off the teeth of the needle cloth, is transported by the airflow and condensed on the web curtain (or dust cage), forming a fiber web with three-dimensional disorderly arrangement of fibers. Our company’s air-laid process does not cause fiber dam

The Fixed Web Process Is Mainly Divided Into Needle Punching And Hot Air.

 

The needle punching process is made of polyester and polypropylene raw materials, and is made after multiple needle punching and appropriate hot rolling treatment. According to different processes and different materials, hundreds of products are made. The needle punching process will form large penetrating pinholes on the surface of the cloth, and the sound absorption will be relatively poor. The needle punching process cannot produce high-weight products.

 

Our company mainly uses hot air technology. Hot air non-woven fabrics belong to one of the hot air bonding (hot rolling, hot air) non-woven fabrics. Hot air non-woven fabrics are non-woven fabrics generated by using hot air on the drying equipment to penetrate the fiber web after the fibers are combed, so that they are heated and bonded. The hot air process can form messy holes on the surface of the cloth, and the sound absorption effect is better than needle punching.

 

Nowadays, people pay more and more attention to the quality of life. The indoor noise is too loud, which sometimes seriously affects our lives. What should we do? At this time, sound insulation is very important. How to choose a good quality sound insulation mat:

 

The Quality of Raw Materials

Other companies may need to add additives in the production process to enhance the physical functions of sound insulation mat such as elasticity, viscosity, durability and tear strength. Inferior additives will not only affect the physical function of sound insulation mat, but also have an important impact on environmental protection function, because some additives are toxic. Our company does not need to use additives in the production process.

 

Is The Flexibility Good?

Some vendors sell some sound insulation mats with poor flexibility at a low price. When buying this kind of sound insulation mat, just look at it directly to see if the flexibility is good. If it is not good, don’t buy it!

 

Smell The Smell

When buying, smell whether the sound insulation mat itself is pungent or has no smell. If you smell a pungent rubber smell, this kind of sound insulation mat itself is not environmentally friendly. Please be cautious when buying it!

 

Look At The Density

You can cut the sound insulation mat with a wallpaper knife and look at the cross section in the sun.
