A Summary of the Knowledge of insulated Magnesium color steel sandwich panel

Magnesium color steel sandwich panel has the characteristics of water-proof, moisture-proof, high temperature resistance, flame-retardant, sound absorption, shock-proof, insect-proof, anti-corrosion, non-toxic, odorless and pollution-free. It can be directly painted, directly veneered, gas lamp, ceramic tile directly. The surface has better coloring, high strength, flexibility, toughness, nail, sawable, sticky and convenient decoration. It can also be combined with a variety of insulation materials to make composite insulation board.

Metal sheet application:

Upper/lower steel plate: thickness is 0.4-1.2 mm. There are color steel plate, galvanized steel plate and stainless steel plate.

Core Material: Magnesium board

Product Specification:

1. Conventional width of machine-made board: 1150 mm, thickness: 40 mm~250 mm, unlimited length

2. Conventional width of hand-made board: 1180 mm, thickness: 40 mm~250 mm, unlimited length

Making magnesium fireproof sandwich panel material ingredients: active high purity magnesium oxide (MgO), high quality magnesium chloride (MgCI), alkali-resistant glass fiber cloth, plant fiber, non-flammable light perlite, chemically stabilized lithopone powder, high polymer, high performance modifier.
