The biggest feature of the mineral wool sound-absorbing board is the outstanding performance of noise reduction, sound absorption, sound insulation and fire prevention, and light weight. Mineral wool sound-absorbing panels are made of mineral wool as the main raw material, plus starch as the main binder, adding appropriate amounts of auxiliary agents and additives, through batching, forming and dehydration, gelatinization and drying, cutting, planing and milling, finishing, spraying, packaging. It is processed by more than ten processes. Mineral wool sound-absorbing board is a ceiling decoration material that integrates various functions such as heat preservation, heat insulation, sound absorption, fire prevention and decoration. High asbestos-free, no needle-like dust, and will not enter the body through the respiratory tract, causing harm to the human body. Mineral wool is a white or light yellow flocculent thrown out by a high-speed centrifuge after melting waste blast furnace slag from iron and steel smelters at high temperature, which is harmless to human body. It is a green building material that turns waste into treasure and is beneficial to the environment. Asbestos will produce dust. When these fine dusts are inhaled into the human body, they will attach and deposit in the lungs, causing lung diseases. Asbestos has been affirmed as a carcinogen by the International Center for Research on Cancer.
There will be many small holes inside the board of the mineral wool sound-absorbing board, which will reduce its density. And these small holes can filter volume, reduce noise, and make its weight greatly reduced, its weight will be about 180 to 450kg per cubic meter. It is a relatively light and energy-efficient building light material. This light material is combined with beautiful patterns. The surface generally has irregular holes (commonly known as: caterpillars) or micro holes (pinholes), etc. A comfortable and reassuring effect, without a heavy and oppressive feeling. In addition, the waste mineral wool sound-absorbing panels can be recycled and reused as raw materials after crushing. Therefore, from the perspective of environmental protection and material reuse, the generation of construction waste can be reduced and recycling can be achieved. my country’s mineral wool decorative sound-absorbing panels have been developed for more than 20 years. Some early mineral wool sound-absorbing panels have completed their historical missions and can be recycled to reduce the generation of garbage and use less mineral products, which is more in line with modern green development. environmental protection concept.
