Expanded perlite must be familiar to everyone, but what are the advantages of expanded perlite? How to identify? These need to be carefully understood!

What are the advantages of expanded perlite?

1. Expanded perlite with its good thermal insulation performance, super stability is well accepted by the market and play its role, and a wide range of applications, with universal practicality, especially in the fire insulation energy saving play excellent performance.

2. It can be said that there are countless excellent performances. It has not only good environmental protection performance, but also widely used economic and social value, extremely convenient construction, easy maintenance, better impact performance than any other thermal insulation material, excellent damp heat resistance and better fire resistance.

3. Among them, the durability has the same life as that of buildings, which completely breaks the boundary of the average service life of 25 years of organic exterior insulation materials. Because the rock energy inorganic insulation material system is inorganic products, never aging. And it is seamless construction, so as to form a full plastic wrapping protection effect on the building.

4. Under normal use conditions, in case of dry, severe cold, high temperature, humidity, electrochemical corrosion or insect, fungus or algae growth, as well as the destruction of serrated animals, object impact and other attacks, it will not cause damage and greatly extend the service life of buildings. The service life of the thermal insulation material is the same as that of the building.

How to identify expanded perlite?

Expanded perlite fire-proof board is a new type of fire-proof door core filling material, which is made of expanded perlite, embedded framework, adhesive and pressure. Expanded perlite is a new kind of lightweight and multifunctional material.

The qualified expanded perlite products can be divided into three types: the density of the first type is 80kg / m3; Class II, 80-150kg / m3; The third kind of material is 150-250kg / m3. The thermal conductivity increases with the increase of density. From the surface, it should be snow-white or light gray white granular, one kind is easy to crush completely by hand, and the third kind is not easy to crush.
