Fiber sound-absorbing spraying materials are dividedinorganic fiber sound-absorbing sprayingandPlant fiber sound-absorbing spraying materialWait.

Sound-absorbing spray materials are not onlysound absorption and noise reductionhas obvious effect, but also a more idealThermal insulation fireproof material. Sound-absorbing spraying is made of organic or inorganic fiber cotton in a certain proportion with a special adhesive mixed after a special spraying machine spraying on the surface of the building. An overall stable and closed porous cotton-like spray coating was formed.Sound-absorbing spraying has the properties of heat preservation, sound absorption and noise reduction, and convenient construction, which provides excellent solutions for the acoustics, energy saving, and heat insulation of many large buildings.Fiber sound-absorbing spray material also has the following characteristics: decorative. Decorative sound-absorbing spraying, because of its technical limitations, is generally a velvet coating with a drop of several millimeters on the surface. Kan Kan

For the inner roof with high space height, the visual effect is acceptable due to the long distance. However, for the walls and tops with low height and close distance, products with better flatness should be selected. The flatness depends first on the manufacturer's construction machinery precision, and then the fine post-processing work of spraying.

1. Color stability: When sound-absorbing spraying is used as the final decorative layer, higher requirements should be put forward for the oxidation resistance, mildew resistance and insect resistance of the product, so as to avoid undesirable states such as yellowing of spraying oxidation and mildew spots, especially for those with heavy water vapor such as swimming pools, this trend will accelerate, and the requirements for this aspect of the product need to reach a harsh level.

2, fire resistance: generally as the indoor top decoration layer of sound absorption spraying, the current national standards generally to doAGrade fire protection, especially in public buildings.

3, the finished product cleaning method: spraying in the long-term use of the library process, more or less, there will be fouling. General spraying products are not allowed to be cleaned, but some advanced spraying are allowed to do cleaning work such as washing and air blowing. Kan
