What we are familiar with is that the thermal conductivity of perlite is very low, so what we are familiar with is the application of perlite in thermal insulation, such as wall insulation and other thermal insulation applications, which we usually contact and understand more. But in the aspect of cold insulation, we usually contact less, but today we are going to give you a detailed introduction in this aspect.

The application of perlite in cold insulation is more in the construction of cold storage, the use of the form is actually very different, but in the cold storage is mainly in the form of perlite plate to use.

Why can perlite play the role of cold insulation? In fact, perlite plate is a kind of material with many micropores, so it has high viscosity for air. In terms of heat transfer, we are familiar with the heat transfer driven by air circulation. If the air flow is small or even negligible, then our heat transfer will be small or even negligible, This is the main reason why perlite is used as insulation material.

In fact, there is another reason for using perlite plate for thermal insulation in cold storage, which is that the quality of perlite is very light, so we will not cause other problems because of the weight of perlite plate.
