Why does Glass Wool Roll Becomes the Favourite of Steel Structure Industry
Posted by:Yolanda Date:26.Jul.2019
With the development of society and the continuous improvement of people's living standards, some large public facilities have been born one after another, such as gymnasium, exhibition hall, library, large conference room, station waiting hall, terminal building, large workshop and warehousing in logistics industry. Their common characteristics are large space, large span, difficult construction, high risk, low requirement for thermal insulation materials, and so on. Light weight, good insulation effect, that is, sound absorption and fire protection, which is difficult to achieve by some traditional insulation materials.
The birth of glass wool felt solved this problem. Glass wool felt is a coil made to meet the needs of large area laying. Its width is fixed and its length can be customized according to the needs of users. Glass wool mat not only maintains the characteristics of heat preservation and insulation, but also has excellent shock absorption and sound absorption characteristics, especially for medium and low frequency and various vibration and noise, which is conducive to reducing noise pollution and improving the working environment. This material can also be tailored arbitrarily according to the need in construction. The sound absorber can be made into plate, column, cone or other special-shaped body according to the requirements. The inner part of the absorber is filled with centrifugal glass cotton felt, and the surface is wrapped with a sound transmission surface layer. Because the absorber has many surfaces, the absorption efficiency is very high. For some places with special requirements, such as high temperature workshop, control room, machine room inner wall, compartment and other facilities, people paste glass cotton felt with aluminum foil, which is heat insulation and radiation resistance. In addition, glass cotton wrap felt is soft in texture and delicate in fibre. It will not stimulate the skin in construction. It is convenient and fast to construct, so it is favored by friends in steel industry.
With the understanding of glass wool felt, its application scope is also expanding. For example, in building interior, transportation and refrigeration equipment, noise absorption and noise reduction treatment; in road noise barrier, in order to prevent noise reflection, it is necessary to take sound absorption measures on the side facing the vehicle, and centrifugal glass wool is often used as filling material, and the surface layer is perforated metal plate.
