Seven characteristics of perlite insulation board

Perlite insulation board is a new type of exterior wall insulation board that integrates heat insulation, heat insulation and waterproof functions. The raw material of perlite insulation board is perlite. Perlite is a volcanic acid lava. The glassy rock formed by rapid cooling is named for its pearl fissure structure. Perlite mines include perlite, obsidian, and turpentine.

Seven characteristics of perlite insulation board:

1.Long life

The current design life of buildings in China is generally 50-100 years, and the life of foamed cement boards is greater than 50 years, which is the same life as buildings.


2, fire insulation

The composite foamed cement insulation board is a class A non-combustible inorganic insulation material, which has good fire resistance. It can maintain its integrity when baked at 1200 degrees for 3 hours. It can be used on buildings to improve the fire resistance of buildings. Because of its closed porosity> 95%, it has good thermal insulation performance.


3.Lightweight shock resistance

The product has a light bulk density, a dry volume, and a density of about 250 kg / cubic. The plate has passed the 1.5 million fatigue resistance tests of the National Testing Center. The plate and the steel structure are welded as a whole to withstand a magnitude 9 earthquake.


4, sound insulation

Because it is formed by porous and numerous independent bubbles, the sound absorption effect is about 5 times higher than that of ordinary concrete, and the sound insulation coefficient is greater than 45dB.


5.Convenient construction and high work efficiency

Convenient construction, short construction period, no need for sand, cement and other materials during construction, simple and efficient material stacking, small volume, less resources such as site equipment, no construction waste, no plastering required after construction is completed. The traditional block wall requires 12 people for 60 minutes of construction, and the use of foamed cement board can be completed in 3 people for 60 minutes, saving labor costs.


6, compressive strength, strong adhesion

Special fiber is used in the composite foamed cement insulation board. The perlite insulation board has increased the compressive strength of the foamed cement board. After inspection by the national professional testing agency, the flexural damage load is more than three times the self-supporting weight (the national standard is 1.5). Times), the compressive strength is above 5 / mpa (national standard is 3.5 / Mpa), and the hanging force is above 1500 / N (national standard is 1000 / N).


7, non-toxic and harmless, environmental protection and energy saving

Composite foamed cement insulation board uses cement and fly ash as the main raw materials for production. It does not burn at high temperatures and does not release toxic chlorine. It is a safe and environmentally friendly material and is supported by domestic industrial policies as a waste product.
