What Is the Function of Rock Wool Produced by a Rock Wool Sandwich Panel Production Line?

Features of Rock Wool Produced by the Rock Wool Sandwich Panel Production Line

The rock wool panels produced by the rock wool sandwich panel production line are made by melting and calcining basalt at high temperatures. Basalt, the main raw material, offers unparalleled advantages in the construction industry, and rock wool panels inherit these superior properties. During construction, rock wool panels are mainly used for thermal insulation of walls, roofs, and buildings, with wall insulation being the most common application in modern construction.

The rock wool panels produced by the sandwich panel production line are particularly suitable for on-site assembly, increasing indoor height, large-span structures, and energy-efficient renovations of old buildings. They also exhibit excellent seismic strain resistance.

These panels offer advantages such as low thermal conductivity, good air permeability, and high fire resistance. They are applicable to energy-saving insulation projects for the exterior walls of newly built, expanded, or renovated residential and public buildings, including external wall insulation, opaque curtain wall insulation, and EPS external insulation systems.

Marine-grade waterproof rock wool insulation panels are produced with added water-repellent agents, providing excellent moisture resistance. These are used for thermal insulation and fireproof partitioning in ships. Hydrophobic rock wool panels are used in vehicles, mobile equipment, cold storage facilities, air-conditioning ducts, and other moisture-prone environments requiring thermal insulation, fire resistance, and moisture control.

Materials and Applications of Rock Wool

Rock wool products are made from basalt as the primary raw material. After being melted at a high temperature (above 1450°C), the molten basalt is spun into inorganic fibers using a high-speed centrifugal device. Specialized binders and anti-dust oils are then added. The fibers are laid down in layers using drum-forming and pendulum systems, and with the aid of dedicated equipment, their arrangement is transformed into a three-dimensional chaotic structure. The final product is a new type of lightweight insulation material formed through a curing process.

Depending on different applications, the production line can yield various forms such as rock wool panels, rock wool blankets, and rock wool shells. In building insulation, rock wool is primarily used for walls, roofs, doors, and floors, with wall insulation being the most crucial application.

In industrial insulation, rock wool is widely used for industrial tanks, boilers, and heat exchangers, and also for insulation and fire protection of ship cabins and ceilings. Rock wool blankets are suitable for insulating complex shapes and high-temperature equipment, while rock wool belts are commonly used for large-diameter pipelines and storage tanks.

Additionally, in some developed countries, granular rock wool is manufactured for ceiling and wall insulation in residential buildings. It can also be used as a spray-on material for coating walls, columns, or furnace surfaces for fireproofing and insulation purposes.

Key Advantages of Rock Wool Panels from Sandwich Panel Production Lines

The rock wool panels produced by the rock wool sandwich panel production line are made primarily from natural volcanic rock, making them a non-combustible building material with outstanding fire-resistant properties. They are classified as Class A fire-resistant materials, effectively preventing the spread of fire. These panels also have excellent dimensional stability, maintaining their shape and structure even under high-temperature fire conditions.
