[Bebel static soundproof windows】 mainly used in home decorating the walls soundproofed, household wall soundproof walls and soundproofed bedrooms among family members use, this product is the best material to replace all other soundproofing materials, its unique damping effect can not be compared to other soundproofing materials, copolymer material is widely used in aircraft, luxury car noise damping, belongs to the high-end sound insulation material, soundproof carpet material, EVA, PE, POE, superfine silicone powder and so on, and the ratio of the material. unique soundproofed damping effect, good toughness, tensile degree can reach up to 200%, with a non-toxic, odorless, fire-retardant characteristics. Families noise control (walls, pipes, ceilings, etc.). Entertainment noise control (KTV private rooms, walls, ceilings, floors, etc.). The office noise governance (light walls, partitions, conference room, etc.). Industrial noise control (plant walls, roofs, equipment, doors, control room soundproofing material market conditions, market quality soundproofing felt uneven, can be described as a deep water, fish, some profiteers with rubber plate or PVC membrane posing as the noise felt, these so-called "soundproofing felt" simply pig nose plug green onions mounted elephant simply can not solve the noise problem, as ordinary consumers, it should be how to identify the noise felt true and false pros and cons ? We can start the noise felt soundproof principle analyzes noise felt noise effects, in addition to its own has a high density, also depends on the damping effect, while the level of the damping effect depends on the viscoelastic understand this principle, when you get the sound insulation felt from below and went to work to identify strengths and weaknesses. [the soundproof windows Bebel static] studied acoustics all know, the higher unit density material better sound insulation. therefore, in order to enhance The noise felt the effect of noise and damping properties, tend to add to increase the density of the material, such as lead powder, copper powder, but the ceruse toxic, copper powder and too expensive, so the use of ultra-fine organic silicon powder as add material. when you get the noise carpet samples, the samples were cut with a knife, then get the sun to observe the cross-section you just cut, will see the white flash powder, silicone generally good soundproofing felt ensure flexibility and under the premise of toughness, density can reach 5kg / m2 (2 mm thick), sound insulation and sound insulation felt really good Another important factor is the flexibility in most cases, soundproof felt with the gypsum board, calcium silicate board pressure cement board sheet, good flexibility can reduce the the rigid plate vibration generated by sound waves, and thus to increase the amount of noise. simplest way of testing the soundproofing felt flexible soundproof felt cut to two or three centimeters wide long bar, and then forced the elongated, relatively easy stretched and slack length can be restored, and so on.
