Thermal insulation cotton is made of aluminum oxide powder, silica powder, clay clinker and other materials, which has the characteristics of high strength, oxidation resistance, light weight, good softness, corrosion resistance and so on. Next, we will introduce the sound insulation effect of thermal insulation cotton and how to choose thermal insulation cotton.
How about the sound insulation effect of thermal insulation cotton
Thermal insulation cotton sound insulation effect is good, this material can not only play a sound insulation effect, but also heat insulation, especially suitable for hotels, ktv and other entertainment venues. In addition, thermal insulation cotton can also be used in the car engine, which can effectively avoid the high temperature of the engine directly transmitted to the hood, so as to protect the hood surface paint, and avoid the hood fog affecting the line of sight when it rains.
How to choose thermal insulation cotton
1, thermal conductivity can be an important indicator to measure the performance of thermal insulation cotton, the smaller the thermal conductivity, the less energy transferred through the material, the better the thermal insulation performance of thermal insulation cotton.
2, the sound absorption effect of thermal insulation cotton depends on the density of thermal insulation cotton in the unit area, the greater the density, the better the sound absorption effect.
3, good insulation cotton should have low moisture absorption, many insulation materials after water absorption, insulation effect will be significantly reduced, because water has a high thermal conductivity.
Is sound insulation cotton the same as thermal insulation cotton
1, cotton materials generally have thermal insulation effect, so sound insulation cotton is a kind of thermal insulation cotton.
2, sound insulation cotton is also called sound-absorbing cotton, which is a sound insulation material and also has the effect of thermal insulation.
3, both materials belong to cotton materials, but the function is not the same. The sound insulation effect of sound insulation cotton is better, and the thermal insulation effect of thermal insulation cotton is better than that of sound insulation cotton.
