Glass wool is a good choice. Glass wool can be said centrifugal, so it is also known as centrifugal glass wool, whose thickness and volume-weight have somewhat effect on its sound absorption property. Meanwhile, its sound absorption property is also affected by the cover material and the structure construction. It is necessary to use centrifugal glass wool properly based on its various characteristics like its appearance, fire-resistant capability and anti-aging ability in application to specific buildings. In addition, centrifugal glass wool can be cut freely and it has a stable physical properties. Glass wool is a product made by adopting peculiar centrifugation technology, the technology that fibering molten glass and then processing the added thermosetting resin-based adhesives with environment-friendly formula to manufacture the final products. It is a felty body with elasticity made by stacking of glass fiber whose diameter keeps merely several micrometers. Centrifugal glass wool's detailed technical characteristics include thermal insualtion, excellent shock absorption and sound absorption, and noise absprption capabilities for low and medium frequency noise and vibration noise in particular. It helps a lot in reducing noise pollution and improving the working environment. Glass wool with aluminum foil veneer has a strong thermal radiation resistance as well, which makes it a superb lining material applied in high temperature workshops, control rooms, inner wall of machine rooms, compartments and flattops.
Glass wool thermal insulation material belongs to A-level fireproof material, while incombustible?material glass wool is categorized into glass fiber, which is a manmade inorganic fiber. Glass wool is a material which fibering melting glass to form cottony shape. Its chemical composition belongs to the classification of glass, being an inorganic fiber. So, it is good shaped with small volume density, low thermal conductivity, good thermal insulation and sound absorption properties, great corrosion resistance as well as stable chemical performance.
Insulated wool is good. Rock wool: It is also known as rock cotton, which belongs to mineral wool. It is a fluffy, short and fine fiber made up raw materials like natural rocks and minerals. Rock wool, whose main raw material are natural rocks like basalt, gabbro, dolomite, iron ore, bauxite and more, is an inorganic fiber made by melting at high temperatures and fibering. Rock wool can serve as the insulation material with ablation resistance and high temperature resistance, the sound-absorbing material and insulation material of buildings and equipment, and the reinforcing material of cement product and rubber for sustituting natural asbestos, and high temperature sealing material, high-temperature filtering material and high-temperature catalyst carrier. 1. Insulation properties: Good thermal insulation is the basic property of rock wool and mineral cotton products. 2. Combustion performance. 3. Sound insulation performance: Rock wool and mineral cotton products have excellent sound insulation and sound absorption performance.
