At present, mineral wool sound-absorbing panels have become the high-quality ceiling decoration materials at home and abroad with the advantages of sound absorption, heat insulation, fire prevention, light weight, non-toxicity, convenient installation and good decorative effect, and have been widely recognized by designers and users. It is one of the most mature materials in the current ceiling decoration materials. But do you know the development history of mineral wool sound-absorbing panels? Did you know that the start of China’s mineral wool sound-absorbing panels is closely related to President Nixon’s visit to China in 1972?
The mineral wool sound-absorbing panel is made of high-quality mineral wool as the base material, adding an appropriate amount of binder and regulator, and is processed through more than ten procedures such as batching, forming and dehydration, gelatinization and drying, cutting and milling, finishing, spraying, and packaging. It is a kind of architectural ceiling decoration material. The USG company in the United States was the first to develop mineral wool sound-absorbing panels in the world. It began to produce mineral wool sound-absorbing panels in 1926, which has a history of a hundred years. Since then, it has continued to develop and expand. In the 1960s, Western Europe, the former Soviet Union, and Japan all carried out the development of mineral wool sound-absorbing panels. In the early 1970s, Japan’s Nitto Textile Co., Ltd. introduced the production of mineral wool sound-absorbing panels from USG Company in the United States. The technology and equipment, after being digested and absorbed, have gradually developed and become the production technology and equipment of mineral wool sound-absorbing panels with their own characteristics. American Armstrong has invested heavily in this field and has become the world’s largest and more influential multinational company producing mineral wool sound-absorbing panels.
However, the development history of mineral wool sound-absorbing panels in my country is relatively late. When it comes to its start, we have to mention the visit of US President Nixon to China in 1972, which affected the overall situation of the world. At that time, Nixon visited China and brought a set of satellite ground receiving station system in China, among which there are mineral wool sound-absorbing panels in the ceiling of the movable room of the satellite receiving station. After the visit to China, the Beijing General Building Materials Factory (former Beijing Cement Brick and Tile Factory) collected samples of the mineral wool sound-absorbing panel, and through the cooperation with the China Construction Research Institute, the first one in China with an annual output of 200,000 square meters was built. The production line of hot-pressed mineral wool sound-absorbing panels has ended the history of not being able to produce mineral wool panels in China and filled the gap of domestic high-end ceiling materials. Once the product was put into the market, it was widely used immediately, and the project was awarded the National Science Progress Award in the 1970s. Since the early 1980s, some local enterprises have gradually entered the industry, which has made the production and application of mineral wool sound-absorbing panels develop rapidly in China. However, due to the low starting point of the initial production line, the production efficiency and product quality are quite different from those of foreign production technology. gap. In the 1980s, Beijing Building Materials Products General Factory introduced a set of mineral wool sound-absorbing panels wet production line with an annual output of 1.38 million square meters through Nittobo Corporation of Japan. species. The production line was put into operation at the beginning of 1987. The production standard adopts the Japanese JIS standard. After the product was put into the market, it was widely used, such as the Beijing Library, CCTV, Changfu Palace Hotel, International Hotel, Great Hall of the People and other national key projects at that time. All use the mineral wool sound-absorbing board products produced by the factory. Since then, my country’s mineral wool sound-absorbing panel production technology and its application have achieved a qualitative leap, reaching the level of advanced countries in the world.
