Expanded perlite board is made of expanded perlite as the main aggregate, mixed with different kinds of cat's cake, stirred, shaped, dried, roasted or cured. It is a non-combustible sheet. It can be used at 900 °C for a long time.
This kind of material has the characteristics of low density, low thermal conductivity, high pressure bearing capacity, convenient construction, economical and durable, etc. It is widely used as thermal insulation material and industrial and thermal insulation equipment and industrial construction equipment and industrial buildings. Insulation, heat insulation and sound absorbing materials for civil building envelopes. Because of its good thermal stability, it is often used as a fire-resistant protective covering material for steel structures.
According to the different types of admixtures, it can be divided into cement expanded perlite plate, water glass expanded perlite plate and phosphate expanded perlite plate. Expanded perlite decorative sound absorbing panels are often used for sound quality processing in public buildings such as theaters, auditoriums, studios, conference rooms, and noise control in factories. They are also used for the ceilings of civil public buildings and interior wall decoration.
