Standard of the China Engineering Construction Standardization Association: "Magnesium Sulfate Foamed Blocks"

The application of magnesium oxide in fire-resistant boards is particularly prominent.

Fire-resistant boards are an essential component of building fire protection systems and are widely used in architectural elements such as walls, ceilings, floors, and partition walls. Magnesium oxide has a melting point as high as 2,800°C, enabling magnesium-oxide-containing fire-resistant boards to maintain structural integrity even in high-temperature fires, slow down the spread of flames, and provide critical safety protection. In addition to their outstanding fire-retardant performance, these boards also boast advantages such as light weight, high strength, water resistance, and mold resistance, making them suitable for a wide range of construction environments.

Bamboo-magnesium fire-resistant board—environmentally friendly and healthy.

Bao-magnesium fire-resistant boards are free of asbestos, formaldehyde, benzene, and harmful radioactive elements. When exposed to fire, they produce no smoke, no toxins, and no odors. The materials used in their production are natural mineral powders and plant fibers, and the manufacturing process involves natural curing with low energy consumption and zero wastewater discharge, making them both energy-efficient and environmentally friendly. During use, the board surface does not shed powder. Thanks to its unique natural microporous structure, these boards can regulate indoor temperature, making living and working spaces more comfortable.

Uses of Magnesium Oxide Fireproof Boards

Glass-magnesium fire-resistant boards serve as a basic intermediate material and must undergo surface finishing before they can be officially put into use. Therefore, the application of glass-magnesium fire-resistant boards is similar to that of wood-based panels: they can be processed using techniques such as sawing, planing, and nailing to create structures for various decorative applications. Finally, these structures are finished with surface coatings like latex paint, wallpaper, or ceramic wall tiles, thereby completing the decoration project. As one of the optional materials for ceiling installations, glass-magnesium fire-resistant boards offer advantages such as being environmentally friendly, energy-efficient, easily sawable, nailable, adhesive-friendly, and paintable and brushable. They are suitable as base materials for both interior and exterior ceilings in residential spaces, office buildings, guesthouses, hotels, shopping malls, hospitals, airports, subways, libraries, convention centers, sports arenas, museums, factories, and other similar venues—on top of which tiles or other similar materials can be further adhered.

Characteristics of Magnesium Oxide Fireproof Boards

Bao-magnesium fireproof boards feature high-temperature resistance, flame retardancy, sound absorption, vibration damping, insect prevention, corrosion resistance, and are non-toxic, odorless, and pollution-free. They can be directly painted or veneered, installed using exhaust nails, and even have tiles laid directly onto them. The surface exhibits excellent colorability, boasts high strength, flexibility with good bend resistance, and is both nailable, sawable, and adhesive—making installation and decoration extremely convenient. Additionally, these boards can be combined with various insulation materials to create composite insulation panels.
