What is the sound insulation effect of thermal insulation cotton? How to choose thermal insulation cotton?

thermal insulation cotton is made of alumina powder, silica powder, clay clinker and other materials, which have the characteristics of high strength, oxidation resistance, light weight, good flexibility, corrosion resistance and so on. Next, we will introduce the sound insulation effect of thermal insulation cotton and how to choose thermal insulation cotton.

What is the sound insulation effect of thermal insulation cotton?

Thermal insulation cotton has a good sound insulation effect. This material not only has sound insulation effect, but also has heat insulation effect, which is especially suitable for hotels, ktv and other entertainment places. In addition, thermal insulation cotton can also be used in automobile engines, which can effectively prevent the high temperature of the engine from directly transmitting to the hood, so as to protect the paint on the hood surface and avoid the fog on the hood from affecting the line of sight in rainy days.

how to choose thermal insulation cotton

1. Thermal conductivity can be an important index to measure the performance of thermal insulation cotton. The smaller the thermal conductivity, the less energy is transferred through the material, and 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 unit area. The greater the density, the better the sound absorption effect.

3. Good thermal insulation cotton should have low hygroscopicity. After many thermal insulation materials absorb water, the thermal insulation effect will be obviously reduced, because water has high thermal conductivity.

Is sound-proof cotton the same as thermal insulation cotton?

1. Cotton materials generally have thermal insulation effect, so sound-proof cotton is a kind of thermal insulation cotton.

2. Sound-insulating cotton, also called sound-absorbing cotton, belongs to sound-insulating materials and also has the effect of heat preservation and insulation.

3. Both materials belong to cotton, but their functions are different. Sound insulation cotton has better sound insulation effect, and thermal insulation cotton has better thermal insulation effect than sound insulation cotton.
