Glass wool is widely used in fields such as construction, industry, and acoustic treatment

Glass wool belongs to a type of glass fiber, which is made by melting natural minerals such as quartz sand, limestone, and dolomite with chemical raw materials such as soda ash and borax, and then using blowing or centrifugal spinning processes. Its chemical composition is similar to glass, and it is an inorganic fiber.

Suggestions for the selection and use of rock wool

Select rock wool with different densities and thicknesses according to specific applications. For example, low-density rock wool (60-80kg/m ³) is suitable for sound absorption and noise reduction, while medium to high-density rock wool (100-150kg/m ³) is suitable for thermal insulation.

Production process of rock wool

Melting system: Natural rocks (such as basalt, dolomite, etc.) are melted at high temperatures in a blast furnace or other melting furnace, with a production capacity of 3.0 tons/hour. The furnace is equipped with oxygen rich, high-temperature combustion air system, and exhaust gas treatment heat exchange system to improve the yield, uniformity, and stability of the melt.
