The working principle of the fire-resistant particleboard is primarily achieved through its unique physical and chemical properties, enabling fire resistance and heat insulation.

The main component of the expanded perlite fireboard is expanded perlite, a type of insulating refractory material primarily made from expanded perlite. The spherical structure of the perlite results in a relatively small surface area, thus offering excellent fire and heat insulation properties. Additionally, the expanded perlite fireboard features lightweight, high strength, good toughness, ease of shaping, and convenient installation, making it outstanding in fire and heat insulation.

In practical applications, fire-resistant pearl board effectively prevents the spread of flames. With its high strength, wear resistance, high-temperature resistance, thermal insulation, and flame-retardant properties, it offers effective fire protection for steel structural projects and more. Additionally, the board features low density, excellent heat insulation, strong adhesion, rapid drying and curing, and is non-toxic and pollution-free. These characteristics make it widely applicable in the fire safety field, including the manufacturing of fire-resistant boards and the formulation of fire-resistant coatings.

In summary, the fire-resistant particleboard, thanks to its unique physical and chemical properties, as well as excellent process performance, offers an efficient fire and heat insulation solution for various application scenarios.
