I. General Introduction
Magnesium oxide board is made of natural materials such as inorganic substances, plant fibers. It is eco-friendly, healthy, and pollution-free, with no asbestos, formaldehyde and radiation. It is an upgraded product that replaces wood board and gypsum board. It has not only the lightweight and flexible properties of wood-based organic boards, but also the fire-resistant and water-resistant properties of inorganic boards.
II. Composition
Magnesium Oxide (MgO): Magnesium oxide is a natural non-toxic inorganic mineral. It is calcined and pulverized into powders and mixed in the magnesium chloride solution.
Magnesium chloride (MgCl2): Add magnesium oxide powder into aqueous solution and stir until it becomes cement slurry.
Perlite (PO4): It is a type of obsidian, which is a vitric rock cooled rapidly from lava in volcanic eruption. It is widely used as an insulating material and added to magnesium oxide boards to enhance its fire resistance.
Wood fiber: Also known as sawdust, is mixed into the cement slurry and acts as an adhesive to assist the overall performance of the product.
Non-woven fabric: It is composed of directional or random fibers, with moisture-proof, breathable, flexible and other characteristics.
Fiberglass mesh: Fiberglass is an inorganic non-metallic material with excellent performance, which increases the strength and toughness in the board.
