Dacheng Xiangdong Perlite Fireproof Board —— Produced by Dacheng Xiangdong Insulation Refractory Material Factory. Contact: 13473696600 / 15731614448
Dacheng Xiangdong's perlite fireproof board is a high-performance insulation and fire-resistant material, typically made using water glass (sodium silicate) with a specific molar ratio. Through a high-temperature hot pressing process, it is formed into plates of various sizes. Inorganic binders such as magnesite cement can also be used to bond perlite or vermiculite, and foaming agents may be added to reduce the weight of the core board for doors. This product is widely used in building partitions and other applications.
Alternatively, organic binders like urea-formaldehyde resin, polyester, protein-based adhesives, or construction glues (such as 107 or 801 glue) can be used. However, some of these may release harmful substances or emit toxic gases when burned. After proper curing and aging, the boards can be used in both normal and high-temperature environments, such as thermal insulation boards, soundproofing boards, and heat-insulating panels.
China’s largest manufacturer of perlite fireproof boards is the CITIC Perlite Factory. It specializes in new wall materials, energy-saving products, and waterproof thermal insulation materials. As an integrated industrial and trade enterprise focused on environmental protection and energy efficiency, they have long been engaged in the production and processing of a wide range of perlite-related products, including:
- Perlite and hydrophobic perlite insulation boards (bricks)
- Expanded perlite
- Perlite insulation pipe profiles
- Closed-cell perlite
- Vitrified microbeads (insulation mortar)
- Perlite filter aids
- Deslagging agents and covering agents
- Horticultural perlite
- Perlite fireproof boards
- Insulating pearl sand
- Bentonite (sodium-based, calcium-based, lithium-based, feed-grade)
- Perlite abrasives
- Hollow microbeads
- Highly efficient activated clay
- White/yellow zeolite powder
- Autoclaved aerated concrete blocks
When inorganic bonding materials are used as the main raw material, and non-ionic or neutral-state binders are applied, the plate structure avoids displacement reactions with metal molecules. Each perlite particle is coated, and the surface forms a protective film, providing excellent water resistance and preventing moisture absorption. The resulting product features high corrosion resistance, low thermal conductivity, moderate bulk density, strong water-repellent properties, and resistance to acids, alkalis, salt, and freeze-thaw cycles.
It also offers high-temperature resistance, good sound insulation, shock absorption, heat insulation, flame retardancy, no black smoke, and no toxic gas emissions after burning (meeting GB/T 20285-2006 and GB 12955-2008 standards). It is suitable for use as a filling board in fire shutters and fire doors, and can replace traditional materials such as aluminum silicate wool, rock wool, glass water-type perlite boards, and foamed magnesite cement perlite boards.
