What is the functional effect of aluminum foil rock cotton blanket? Aluminum foil rock wool blanket is a composite insulation material that combines the base material of rock wool and the cover layer of aluminum foil. This material is widely used in the fields of building exterior walls, roof insulation, industrial pipeline insulation, and petrochemical equipment. So what is the functional effect of aluminum foil rock wool blanket? What are the advantages of aluminum foil rock cotton blankets? Below, the editor will explain them in detail to you.

What are the functional advantages of aluminum foil rock cotton blanket?

1. Efficient insulation, significant energy saving and consumption reduction: Made from natural basalt as raw material, melted and fiberized at 1450 ℃, the core thermal conductivity is as low as 0.034-0.045W/(m · K) (better than the industry average), and combined with high-purity aluminum foil veneer with a surface reflectivity of 97%, it can achieve dual insulation
2. A-level fire prevention, safety protection without dead corners: The combustion performance meets the A1 level non combustible level of GB 8624-2012 standard, and the maximum operating temperature can reach 750 ℃. It is recommended to use it for a long time at a temperature of 650 ℃. Even in the face of high-temperature radiation from steel plant kilns or sudden fires, it can maintain structural integrity for more than 2 hours without burning, dripping, or releasing toxic or harmful gases.
3. Moisture and corrosion resistance, doubling service life: The aluminum foil veneer is treated with special anodizing, with a moisture permeability as low as 0.02g/(㎡· h) and a water vapor adsorption rate of ≤ 1%, which can tightly block the penetration of water vapor in the high humidity environment of the steel plant and prevent the rock wool core material from absorbing moisture and powdering;
4. Noise reduction and sound insulation for a more comfortable working environment: Rock wool core material fibers are interlaced to form a three-dimensional mesh structure, combined with the barrier effect of aluminum foil veneer. The sound absorption and noise reduction effect has been tested according to ASTM C423 standard, with an average noise reduction coefficient (NRC) of 1.05, which can effectively absorb the mid to low frequency noise generated by boiler operation and pipeline vibration. After application in the steel plant workshop, the measured environmental noise decreased from 85dB to below 60dB, meeting the industrial operation safety noise standard, creating a more comfortable working environment for operators and improving their work focus.
