*net weight: 20KG/m² The mechanism hollow glass magnesium composite board (purification board) is made of colored coated steel plate as the surface material, hollow glass magnesium as the core material, and pressure composite with thermosetting adhesive in a continuous forming machine. Glass magnesium board is made from a ternary system of magnesium oxide, magnesium chloride, and water, which is configured and modified with additives. The stable performance magnesium based cementitious material is reinforced with medium alkaline glass fiber mesh and filled with lightweight materials to form a new type of non combustible decorative material. It has the characteristics of fire prevention, waterproofing, odorless and non-toxic, non freezing, non rotting, non cracking, unchanged, non combustible, high strength and light weight. |
