Glass wool, rock wool, aluminum silicate cotton belongs to the same fiber materials, can be used as thermal insulation materials, with a certain degree of thermal stability, but the thermal conductivity and stability of these three materials are different, glass wool and rock wool thermal conductivity is generally less than aluminum silicate cotton, aluminum silicate thermal conductivity W / (m.k) ≤ 0.07, and glass wool can be as low as 0.032 W / (m.k). Because it is a fiber material, these three materials have sound absorption properties, generally speaking, the sound absorption effect of glass wool is better than that of rock wool, and the thermal insulation effect is better than that of glass wool, which is often used as external wall insulation material.
Glass wool insulation material
Glass wool, rock wool, aluminum silicate cotton is a kind of insulation, heat insulation sound absorbing materials, the difference between these three, first of all, the difference in high temperature resistance, which determines the difference in their use, aluminum silicate cotton scientific name ceramic fiber cotton, is an almost pure inorganic fiber insulation material, through flinging, silk process or spray blower, art production, with high strength, high tear performance, mechanical processing performance, has become the current industrial kiln wall lining insulation materials, replaceable, refractory bricks. Rock wool is commonly used as external wall insulation and high-temperature industrial equipment insulation and energy saving, about can withstand about 800 degrees of high temperature; and glass wool is resistant to high temperature of about 200 degrees, commonly used for buildings, air conditioning and other equipment system insulation, but also because of the outstanding sound absorption performance, often used as sound absorbing materials, such as sound absorbing bodies, sound insulation walls and other applications.
Rock wool insulation material
The above is the difference between glass wool, rock wool, aluminum silicate cotton and other materials, the same belongs to the insulation material, but the specific use varies due to the different properties of the material, but can be more suitable for the personalized needs of the industry, Youtsen hopes to help everyone, can have a more comprehensive understanding of the insulation materials, reasonable choice of insulation cotton materials.
