Rock wool boardIs a natural basalt as main raw material, after high-temperature melting, artificial inorganic fiber made by the high-speed centrifugal equipment, while adding a special binder and dust oil, then heat cured, made into a variety ofspecifications, requirementsRock wool insulation products.
Specification: (mm) length 1000, width 630, thickness 30-120
Bulk density: (kg/m3) 80, 100, 120, 150
Applications
Construction industry - building exterior insulation wall curtain wall roof and building envelope thermal insulation sound absorption noise reduction
Petrochemical industry - petroleum, electric power, chemical industry equipment, thermal insulation acoustic noise reduction
Mining industry - industrial furnace oven large-caliber tank and ship insulation and fire prevention.

Centrifugal glass wool internal fiber slender, low thermal conductivity of the system, well imprison air, so can not move, and put an end to the air, the convective heat transfer, rapid attenuation of sound transmission, and thus play the effectivenessof thermal insulation and sound absorption, centrifugalglass wool into the glass woolfelt in rolls and glass wool board.
The glass wool felt in rolls steel construction, thermal insulation, sound absorptionmaterial, mainly divided into prime volume mat and veneer blanket rolls, and applied toindustrial plant, warehouse, public facilities, exhibition centers, shopping malls, frozen warehouse, and a variety of indoor playgrounds, sports grounds and other buildings.
Glass wool board to impose thermosetting binder, by pressure, heat curing the moldedplates, are widely used in the field of commercial, industrial, and residential buildingheating, ventilation, air conditioning, conditioning, energy-saving insulation, noisecontrol, to improve the role of indoor air quality.
Unique advantages
· Acoustic noise reduction can effectively prevent sound from spreading.
· Easy for construction Cutting.
· Antisepsis, anti-aging, anti-corrosion guarantee a healthy environment.
Class A fire A1, permanent non-combustible.
· Low moisture absorption, physical properties and stability.
· Strong vibration resistance and high durability
