Sanded Magnesium Sulfate Oxide MGO Fireproof Board,  (also known as sanded MGO board) is a high-performance fireproof panel made from magnesium oxide (MgO) as the main base material. It forms a ternary system with magnesium chloride (MgCl₂) or magnesium sulfate (MgSO₄), water, and various additives, manufactured through specific processes. One side is a smooth surface, and the other undergoes special sanding treatment to create a uniform and delicate frosted texture-hence it is also called "single-sided sanded magnesium oxide board".

1. Excellent Fire Resistance

• Class A1 non-combustible : Complies with GB8624-2012 standard, with zero sustained flame combustion time.

• High-temperature resistance : Does not burn at 800℃ and has no open flames at 1200℃, with a fire resistance limit exceeding 3 hours.

• Releases water vapor when exposed to fire : Moisture inside the board converts to water vapor at high temperatures, absorbing a lot of heat energy and delaying the spread of fire.

2. Superior Physical Properties

• Lightweight and high-strength : Density of 0.85-1.27g/cm³, weight is only 1/3 of traditional boards, flexural strength ≥14MPa, and impact strength up to 25MPa.

• Waterproof and moisture-proof : Can be soaked for 100 days with physical property changes <3%, suitable for humid environments.

• Dimensional stability : Not prone to deformation, strong weather resistance, and remains stable under dry-wet cycles.

• Sound and thermal insulation : Thermal conductivity of 0.216W/(m·K) and sound insulation performance up to STC 53-54, significantly reducing energy consumption.

3. Environmental Protection and Health

• 100% free of asbestos, formaldehyde and other harmful substances, non-toxic and odorless, green and environmentally friendly.

• Antibacterial and mildew-proof : Naturally inhibits microorganisms such as mold and fungi, suitable for high-humidity environments.

• Non-radioactive : Made of natural raw materials, no pollution during production, meeting green building material standards.

4. Easy Processing

• Can be nailed, sawn, planed, and bonded , easy to construct, saving man-hours.

• Good surface compatibility : The frosted surface is particularly suitable for lamination with PVC film, HPL boards, decorative paper, etc., enhancing decorative effects.

• Can be directly tiled or painted , meeting diverse decoration needs.

Differences from Ordinary Magnesium Oxide Boards

Installation Points

1. Preparation Work

• Material inspection : The board should be flat without cracks, uniform in thickness, and neat in edges.

• Environmental requirements : Installation temperature 15-30℃, relative humidity ≤70%, avoiding humid environments.

• Tool preparation : Nail gun, electric saw, sandpaper, special adhesive, etc.

2. Installation Steps

Base treatment : Clean, sand, and degrease the wall to ensure it is flat and dry.

Keel installation : Fix light steel or wooden keels at the designed spacing (usually 400-600mm) to ensure levelness and verticality.

Board fixing :

• The frosted side faces outward (decorative surface), and the smooth side faces inward.

• Fix with nails or screws, nail spacing ≤300mm, edge distance ≤150mm.

• The nail head should be slightly embedded in the board surface to avoid protruding.

Joint treatment :

• Reserve 3-5mm expansion joints between boards to prevent deformation due to thermal expansion and contraction.

• Fill with special joint filler, then paste glass fiber mesh for reinforcement.

• Scrape putty on the surface to ensure it is flat and seamless.
