Magnesium includes the functionality of gypsum (plasterboard) and gypsum fiber board (gypsum sheet) having a large number of additional advantages. Universal leaf decoration material, based on chips chloride magnesium, with a facet, reinforced on both sides with fiberglass. 40% lighter gypsum fiber, durable, waterproof, smooth, non-flammable! Magnesium – a material category A (for interior and exterior). Used for the walls (8, 10 mm), ceilings, window slopes (6 mm), gender (10, 12 mm) in residential and industrial premises. It is used in a room with high humidity to 80% and a room with high demands on fire safety. Is indispensable in building and finishing jobs. Increased water resistance and adhesion property to the paint and finishing materials allow the use of magnesium with little or no further processing.
The material is suitable for installation of walls, partitions, ceilings and finishes at wall surfaces, columns, slabs, can give the necessary form a curved surface. On magnesium has no significant action with distilled water, hydrofluoric acid in any concentration, chrome acid, aqueous solutions of fluorides, etc. Not afraid of caustic alkali, kerosene, gasoline, mineral oils. In processing the surface of the sheet may be used various kinds of fillers, paints and adhesives. Surface is ready for painting, glueing to any decorative materials: wallpaper, and aluminum-composite panels, veneer, plastic, chipboard, ceramic tiles, glass and mirror tiles, which gives freedom for the designer’s imagination. Technical characteristics of magnesium Density – 1.01 g/cm3. Resistance force on a bend in the dry state – 17 MPa.
Resistance force on a bend in wet conditions – 21 MPa. The coefficient of hygroscopic strain (change in shape when wet) – Not more than 0.26%. When placed in water (100 days) does not swell and does not lose its properties. High moisture resistance: resistant to moisture and mold. The hardness of the front surface – 52.7 MPa. Impact strength (impact resistance) – no cracks, splits, penetrating injuries. Frost resistance cycles – 50. Coefficient of thermal conductivity – 0.316 W / m Coefficient of thermal expansion without change. Reducing the size of exposed high temperatures – less than 1%. Fire resistance – at thicknesses of 6 mm can withstand open flame (up to 1200 C) for two hours without change, without separation of toxic substances. Flammability class A (GOST 30244). Color – white. Security – does not contain any of harmful substances, it does not emit toxic, harmful substances, even when heated and can be used for decoration of public premises. Has no odor.
