Description
S series insulation cotton is a high-temperature thermal insulation material made from high-purity raw materials such as silicon dioxide, aluminum oxide, calcium oxide, boron oxide, and magnesium oxide. These materials are spun into micro-fine fibers using a high-speed centrifuge at a temperature of 1200 degrees Celsius, then uniformly distributed and mixed with needle punching process.
Physical properties:
1. Good thermal insulation
According to the physical principle, the thermal conductivity of gas is small, and there are many small air holes inside the good thermal insulation material. The smaller the air holes, the lower the convection heat transfer and the closer to the vacuum state. Our fiberglass blanket has numerous tiny pores, and the fibers are irregularly arranged. It is an excellent insulating material with heat conductivity coefficient between 0.02 and 0.04W/m.K.
2. flame retardant
The main components of glass fiber blanket are silicate compounds, which have non-flammability, high temperature resistance and no odor.
3. Sound absorption
When the acoustic wave invades the fiberglass wool, the acoustic energy is drawn in large quantities due to friction with the fiber and pores of different sizes. Generally speaking, the sound absorption rate can be up to 90%, is a good anti-noise sound material.
4. High insulation
Glass fiber is of high temperature resistance, stable chemical performance, non - conductive is a good electrical insulation material. Dielectric constant: 6.1 -- 6.5; Ω volume resistance coefficient: 1000-2000 cm
5. Corrosion resistance
Glass wool is non - absorbent, non - corrosive, non - mildew and stable.
