Rock wool board, also known as rock wool insulation decorative board, is basalt as the main raw material, by high temperature melting processing of inorganic fiberboard, june 1981 successful test rock wool board is a new type of heat preservation, flame insulation, sound absorption material.
Rock wool board is suitable for thermal insulation and sound insulation of industrial equipment, buildings, ships, etc., and is widely used in petroleum, chemical, metallurgy, ship berthing, textile and other industrial boilers and equipment pipeline insulation in modern times, and is also commonly used in the insulation and sound absorption of partition walls, ceilings and interior and exterior walls in the construction industry, and is also used for fire prevention and noise reduction of building partition walls, firewalls, fire doors and elevator shafts.
Rock wool, that is, a kind of external thermal insulation material for exterior walls. While the organic insulation materials with a market share of 90% are stagnant, rock wool, as an exterior wall insulation inorganic material that has reached fire protection grade a, has ushered in an unprecedented market opportunity.
The raw material of the exterior wall rock wool board is made of natural volcanic rock, which is a non-combustible building material fireproof material.
Main fire characteristics:
(1) it has the highest fire rating a1, which can effectively prevent the spread of fire.
(2) the size is very stable and will not elongate, shrink or deform in a fire.
(3) high temperature resistance, melting point higher than 1000 °c.
(4) no smoke or burning droplets/debris are produced in the fire.
(5) substances and gases harmful to the environment will not be released in a fire.
The fiber of the exterior wall rock wool board is slender and flexible, and the content of slag balls is low. Therefore, the thermal conductivity is low and it has an excellent thermal insulation effect.
Sound absorption and noise reduction
Rock wool is an ideal sound insulation material, and a large number of slender fibers form a porous connection structure, which determines that shida rock wool is an excellent sound absorption and noise reduction material.
The hydrophobic rate of hydrophobic rock wool products can reach 99.9%; very low water absorption, no capillary penetration.
In the environment of high relative humidity, the volume moisture absorption rate of rock wool is less than 0.2%, and the mass moisture absorption rate is less than 0.3% according to the astmc1104 or astm1104m method.
Rock wool chemical stability, ph value of 7-8, neutral or weak alkaline, carbon steel, stainless steel,
Aluminum and other metal materials are not corrosive.
Safe and environmentally friendly
Rock wool has been tested to not contain asbestos, cfc, hfc, hcfc and other environmentally harmful substances. It will not be corroded or produce mildew and bacteria. (rock wool has been recognized as a non-carcinogen by the international agency for research on cancer.
