Rock wool board is basalt as the main raw material, after high temperature melting, adding the right amount of binder, curing processing and made of various specifications of rock wool products. This product has excellent fireproof, heat preservation and sound absorption performance. It is mainly used for thermal insulation and sound insulation of building walls and roofs; fire prevention and noise reduction of building partitions, firewalls, fire doors and elevator shafts; it is suitable for thermal insulation and sound insulation of industrial equipment, buildings, and ships. Rock wool products are widely used in construction, petroleum, electric power, metallurgy, textile, national defense, transportation and other industries. It is an ideal material for heat insulation and sound insulation of industrial equipment such as pipeline storage tanks, boilers, flue, heat exchangers, fans, vehicles and ships. This product construction and installation convenience, energy saving effect is remarkable, has the very high performance price ratio. Rock wool board in the plane and curvature radius of the larger tank, boiler, large steel structure, glass curtain wall external insulation and other fields. Paste aluminum foil more to meet the HVAC air duct, cold and warm water pipe insulation and water vapor barrier needs and building insulation needs. Make indoor warm in winter and cool in summer, four seasons comfortable.

Marine and hydrophobic rock wool insulation board is added with hydrophobic agent during production, which has good moisture resistance. Marine rock wool board is used for thermal insulation and fire partition of ships; hydrophobic rock wool board is used for vehicles, mobile equipment, cold storage engineering, air conditioning pipes, thermal insulation and fire protection in humid environment and applications with certain requirements for moisture-proof. Rock wool board is mainly produced by the pendulum method of hydrophobic rock wool board for thermal insulation material. Grade A1-hydrophobic rock wool board is melted by cupola (1400), centrifuged into fiber at high speed by a four-roller centrifuge, sprayed with a small amount of binder, and then collected by a capture belt. Pendulum craft cloth cotton. Heat and cure. Cutting to form products of different specifications and uses, and at the same time, it can also be deep-processed into seam felt. Shell and veneer products, etc. High strength mineral rock wool board has high mechanical strength, suitable for building external insulation-roof and wall, can also be used for color steel sandwich panel production and other high mechanical strength requirements. Density in 80kg/m3-200kg/m3 thickness: 15mm-180mm

rock wool board performance indicators:

Selection of veneers:

In different working environments, rock wool boards require anti-condensation and moisture-proof functions, which requires a protective layer to be pasted on the outer layer of thermal insulation materials. Our company has a variety of veneers to choose from.

Packing method:

According to the thickness of the customer needs to determine the number of rock wool sheets per pack, the normal packaging thickness is about 300-400mm. For the needs of logistics distribution, rock wool adopts two packaging methods: heat shrinkage and full closure.
