详情描述
The working principle of expanded perlite fire-resistant insulating board mainly relies on its unique physical and chemical properties, which enable it to maintain stability in high-temperature environments while providing excellent thermal insulation. Made primarily from expanded perlite, which is a silicate-alumina glass hollow bead floated from the fly ash of thermal power plants, the board features light weight, thin walls, hollow structure, and a smooth surface. It is highly resistant to high temperatures and offers superior thermal insulation. Utilizing these characteristics, expanded perlite is used to manufacture high-quality thermal insulation fire-resistant materials with excellent thermal retention properties.
The production of expanded perlite fire-resistant insulation boards utilizes a semi-dry molding process, which is simple and does not require finishing operations. This material can withstand temperatures up to 1350°C, offering excellent fire and heat insulation properties. It provides effective solutions for building fire prevention, explosion-proofing, and smoke extraction. In case of a fire, the expanded perlite fire-resistant insulation board remains stable, does not burn, and effectively prevents the spread of flames, thereby offering additional safety to the structure. Moreover, the application of expanded perlite fire-resistant insulation boards extends beyond the construction sector, being widely used in metallurgical engineering, energy fields, and more, showcasing their versatility and practicality.
