Characteristics Of Rock Wool Board
May 23, 2022
Fire Prevention Characteristics Of Rock Wool Board:
The raw material of the rock wool board for the exterior wall is natural volcanic rock, which is a noncombustible building material and fireproof material.
Main fire protection characteristics:
⊙ it has the highest fire rating of A1, which can effectively prevent the spread of fire.
⊙ the size is very stable and will not stretch, shrink or deform in the fire.
⊙ high-temperature resistance, a melting point higher than 1000 ℃.
⊙ no smoke or burning droplets/debris in the fire.
⊙ substances and gases harmful to the environment will not be released in a fire.
Thermal Insulation Characteristics Of Rock Wool Board
The outer wall rock wool board has thin and flexible fiber and low slag ball content. Therefore, it has low thermal conductivity and excellent heat preservation effect.
Sound absorption and noise reduction
Rock wool is an ideal sound insulation material. A large number of slender fibers form a porous connection structure, which determines that rock wool is an excellent sound absorption and noise reduction material.
Hydrophobicity Characteristics Of Rock Wool Board:
The hydrophobic rate of hydrophobic rock wool products can reach 99.9%; with Very low water absorption, and no capillary penetration.
Moisture resistance Characteristics Of Rock Wool Board:
In an environment with high relative humidity, the volume moisture absorption rate of rock wool is less than 0.2%. According to astmc1104 or astm1104m, the mass moisture absorption rate is less than 0.3%.
Noncorrosive Characteristics Of Rock Wool Board:
The chemical property of rock wool is stable, the pH value is 7-8, and it is neutral or weakly alkaline. It is suitable for carbon steel, stainless steel
Aluminum and other metal materials are free of corrosion.
Safety and Environmental Protection Characteristics Of Rock Wool Board:
Rock wool does not contain asbestos, CFC, HFC, HCFC, and other substances harmful to the environment. It will not be corroded or produce mildew and bacteria. (rock wool has been recognized as a noncarcinogen by the International Cancer Research Authority)
