What is the good heat insulation effect of glass fiber and aluminum silicate fiber, what are their respective advantages and disadvantages?
Advantages and disadvantages of aluminum silicate fiber: high temperature insulation, heat preservation, fire resistance, noise reduction, insulation, light weight. Disadvantages: compressive resistance, bending force is relatively poor, easy to produce dust, waterproof performance is not very good.
Advantages and disadvantages of glass fiber: advantages: good insulation, good heat resistance, good corrosion resistance, high mechanical strength, low water absorption, low price. Disadvantages: brittle, poor wear resistance.
Applicability: glass fiber (melting point 680 degrees) belongs to medium and low temperature insulation material, suitable temperature is below 700 degrees, aluminum silicate fiber belongs to high temperature insulation material, use fire temperature 1000~1790 degrees.
Adiabatic effect: glass fiber thermal conductivity at room temperature was about 0.056, the thermal conductivity at room temperature is about 0.035, due to the lower thermal conductivity, moisturizing effect is better, so the material characteristics of aluminum silicate fiber insulation effect is good, but also with the insulation effect of fiber compression density, can not be generalized.
