Noise is a serious problem in urban pollution. People used to hear whistles outside when closing windows at home, which made their emotions worse. Rock wool is an ideal soundproofing material. A large amount of slender fibers form a porous structure, which determines that rock wool is an excellent sound-absorbing and noise reducing material. The sound insulation effect is ≥ 30dB, effectively reducing the interference of external noise and making it appear inside the building walls. Insulation and sound insulation materials, rock wool composite panels, are applied inside the body.
事实上，岩棉复合板通常用于轻质墙体的隔音。这种轻质墙的典型结构是：石膏板+龙骨+岩棉板+石膏板。其中，隔音的主要功能是岩棉复合板，它吸收一些通过石膏板的声波，减少声波在石膏板，龙骨和龙骨之间形成的空腔中的来回反射。石膏板，从而实现墙体的改善。隔音的作用。结果表明，填充密度为80-150 kg / m3的岩棉复合板后的轻质墙体比没有添加岩棉的石膏板高8-15 dB。
In fact, rock wool composite panels are commonly used for sound insulation of lightweight walls. The typical structure of this lightweight wall is: gypsum board+keel+rock wool board+gypsum board. The main function of sound insulation is rock wool composite board, which absorbs some sound waves passing through the gypsum board and reduces the back and forth reflection of sound waves in the cavity formed between the gypsum board, keel, and keel. Gypsum board to achieve wall improvement. The role of sound insulation. The results showed that the lightweight wall filled with rock wool composite board with a density of 80-150 kg/m3 was 8-15 dB higher than the gypsum board without rock wool added.
However, some polyurethane foam composite boards on the market have added too much colloid, which will cause the rock wool composite board to droop directly, directly affecting its fire resistance and sound insulation. The application of these materials in construction engineering will inevitably affect the thermal insulation and fire resistance performance of the building project. In the future, if a fire occurs, it will be a dangerous building.
