what are the raw materials for mineral wool ?

Mineral wool is made from a variety of raw materials, including:

• Basalt: A volcanic rock
• Diabase: A type of igneous rock
• Dolomite: A sedimentary rock composed of calcium magnesium carbonate
• Sand: Made up of small grains of silica
• Limestone: A sedimentary rock composed of calcium carbonate
• Soda ash: A sodium carbonate compound
• Recycled materials: Such as cullet (broken glass) and slag (a by-product of metal production)

The specific raw materials used will vary depending on the type of mineral wool being produced. For example, rock wool is made primarily from basalt and diabase, while glass wool is made primarily from sand and limestone.

Recycled materials are increasingly being used in the production of mineral wool, as this helps to reduce the environmental impact of the process. For example, some manufacturers use up to 85% recycled glass cullet in the production of glass wool.

Once the raw materials have been collected, they are weighed and proportioned according to the desired properties of the finished product. The raw materials are then melted in a furnace at high temperatures, typically between 1,300°C and 1,500°C. This process creates a molten liquid.

The molten liquid is then spun into fibers using a variety of methods, such as centrifugal spinning or blowing. The fibers are typically very fine, with diameters on the order of micrometers. The fibers are then cured in a binder to give them strength and stability. The binder can be either organic (such as resin) or inorganic (such as clay).

The cured fibers are then cut to size and packaged for sale. Mineral wool insulation materials can be produced in a variety of forms, including batts, rolls, and loose-fill insulation. They are also available in a variety of densities to meet the needs of different applications.

Mineral wool is a versatile and sustainable insulation material with a wide range of applications. You just cut it with fast wire machine.It is used to insulate homes, businesses, and industrial facilities to improve energy efficiency, reduce noise levels, and protect against fire.
