In recent years, insulation cotton manufacturers have developed rapidly, and various products such as glass wool and its products, rock wool and its products, silicates, etc. have enriched the entire insulation industry. Insulation capacity has always been an important factor to consider when choosing insulation cotton. So, what are the factors that affect the insulation performance of insulation cotton?
(1) Cotton felt bulk density
As is well known, heat transfer occurs through convection, conduction, and radiation, with convection playing a dominant role in natural environments. As the density of insulation cotton such as glass wool increases, the internal pores and aperture gradually decrease, making it difficult for air to pass through the interior of the insulation cotton, thus ensuring its excellent insulation properties;
(2) Layered structure of insulation cotton
The layered structure has a certain impact on thermal conductivity, which is conducive to dense overlap and uniform dispersion between fibers, reducing thermal convection. When heat is transferred between layers, the layered structure increases the heat transfer path, consumes more heat, and receives less heat, thereby reducing heat loss and improving the insulation capacity of the insulation cotton.
The above are the main reasons that affect the insulation capacity of insulation cotton, playing a leading role and also an important factor to consider when choosing insulation cotton products.
