Product Description
particles noise reduction material first select specific mesh inorganic particles, such as natural sand, slag particles and etc. And covering them with well-proportioned and ultrathin gel solvent on all the particle surface, thus they will form a certain angle coefficient coated particles. The particles under the action of external force which makes the surface of curing effect. The tiny particles will like be welded together. Between the particles, it will naturally form large, irregular, interconnected tiny pore.
In the polymerization process, the ratio of particle size and polymerization method can be accurately controlled, which determines the size of the inner pore and their arrangement. Thus according to the actual demand, it can custom design and produce noise reduction product of different acoustic characteristics. This product will have many advantages of high strength, fire prevention, moisture proof, frost resistance and ageing resistance. Also by using green cementing material, particles products without any harmful volatile matter which is environment friendly acoustic material.
Sound barrier is divided into BG and BZ types by compound form. BM type sound absorption material is particulate material, and the skeleton is metal, and sound insulation layer is made from metal material. BZ type sound absorption material is particulate material, and the shape is folded plate shape, and there are cavities in it, and sound insulation layer is made from metal material.
Product Details
Specifications | Acoustic feature | Application |

Basic performance
Fire prevention | combustion performance as the a-class non-combustible, can be widely used in various places |
Sound absorption | adjustable sound absorption in high, middle and low frequency, can meet all kinds of sound absorption requirements |
Environment friendly | the total volatile matter (TVOC) is far lower than the national standard of 0.5 |
Moisture proof | bulking factor is only 0.18%, with excellent moisture proof performance |
Frost resistance | after the freeze-thaw cycle test, no exfoliating and cracking phenomenon |
Impact resistance | impact strength is better than that of cement fiberboard with same thickness |
Ageing resistance | uv resistance test results show that the performance remains the same |
Adornment | can use natural colored sand which make a simple rustic style |
Typical Technical Features
1. High, medium and low frequency sound absorption features of particulate sound absorption materials are closely related to the size and quantity of tiny pores between particles, structure form, thickness of plate, size of cavity behind plate, etc. Sound absorption frequency features can be adjusted by regulating the particle size, plate thickness and cavity size to meet the high, medium and low frequency sound absorption requirements. In the practical engineering, the targeted design and selection of particulate materials (structure) in accordance with acoustic design requirements will get twice the result with half the effort;
2. Sound absorption features of particulate sound absorption materials have nothing to do with the category of particles, and when other conditions are unchanged, sound absorption structure property is changes slightly even if the material of particulate is changed.
3. Acoustic Property of sound absorption structure of particulate plate with the thickness of not more than 10mm can be forecasted based on the sound absorption theory of microperforated panel;
4. Sound absorption property of particulate sound absorption materials is related to the appearance of particles, and the coefficient of angularity will affect the flow resistance of materials and then affect sound absorption property.
Color of natural ore grain surface
Product color is divided into artificial spraying and existed natural color. There are 27 kinds of natural color sand available. Raw materials are made of selected marble or granite and etc that have been crushing, grinding then born with natural-like color. According to customer requirements, it will be sprayed with related paints.
Product Advantages
Stable Acoustic Property | 1. It belongs to fiberless sound absorption material, and is used for outdoor places that are soaked by rainwater or subject to vibration to prevent settling. |
2. The dust on the surface can be washed away by rain, and sound absorption property won’t be affected. | |
3. It has the sound absorption mechanism of porous material and microperforated panel, and relies less on installation conditions. | |
Excellent environmental protection property | 1. It can directly contact with the human skin, and won’t result in skin itching and other discomforts. |
2. It is characterized by excellent weather resistance, acid and alkali resistance, and won’t be pulverized for long-term use. | |
3. It meets green and environmental protection material standard, and is free of formaldehyde and other harmful ingredients, and TVOC content is 0.096. | |
Low maintenance cost | 1. It is resistant to acid and alkali and salt spray corrosion, and antiseptic treatment is not required. |
2. Natural colored sand can be selected for its strong weather resistance and non-fading property for long-term outdoor use. | |
3. No ground wire is required as it is insulated. | |
Low disposal cost | The scrapping of glass wool and other fiber materials after use will result in secondary environment pollution, and need high disposal expenses, but particulate materials can be directly landfilled, and won’t cause pollution, or can be recycled and reused.
