Magnesium Oxysulfide Sandwich Panel

Product Details

Magnesium oxysulfide sandwich panel is a new type of building cladding material made by combining magnesium oxysulfide adhesive material as the core with high-strength color-coated steel sheets, stainless steel sheets, or galvanized steel sheets through an automated composite process. Magnesium oxysulfide panels use magnesium oxide, magnesium sulfate, and other inorganic materials as main raw materials, processed through specific production processes, and are a green and environmentally friendly new type of purification and insulation material.

Magnesium oxysulfide sandwich panels fully utilize the unique properties of magnesium oxysulfide materials, exhibiting significant advantages in fire resistance, moisture resistance, anti-delamination, high strength, thermal insulation, heat insulation, and sound absorption. It overcomes the shortcomings of some color-coated steel purification panel core materials on the market in terms of strength, bending load-bearing capacity, and thermal insulation effect, and is especially suitable for high-end building scenarios with stringent fire resistance and cleanliness requirements.

Specifications of Magnesium Oxysulfide Sandwich Panel

Optional panel materials include: PE polyester, PVDF (fluorocarbon), chlorinated steel board, antistatic board, conductive board, stainless steel board, antibacterial board, PET board, etc. Connection methods include tongue-and-groove joints or male-female interlocking joints.

Performance Advantages

🔥 Excellent Fire Resistance (A1 Non-combustible)

Magnesium oxysulfide sandwich panel achieve an A1 fire resistance rating, classifying them as non-combustible materials. Testing shows that the 50mm thick product has a fire resistance rating of over 60 minutes, with some thicker plates reaching 2.5 hours. It burns without smoke or toxicity, with smoke toxicity reaching AQ1 level (safety level), effectively blocking flame spread and providing a solid guarantee for life and property safety.

⚡ Lightweight and High-Strength, Excellent Bending Load Capacity

At a density of 150kg/m³, the magnesium oxysulfate board has a compressive strength of over 0.5MPa. After modification, the compressive strength can reach 60MPa, and the flexural strength can reach 9MPa. The bending load capacity reaches 4.41 KN/m², far exceeding ordinary cleanroom boards. It is particularly suitable as a ceiling panel for cleanrooms or accessible roofs, as it is not easily deformed and has a long service life.

💧 Excellent Moisture Resistance and Water Resistance, Extremely Low Water Absorption

The water absorption rate of the magnesium oxysulfide sandwich panel is as low as ≤0.1% (V/V, 24hr), making it difficult for moisture to penetrate. It maintains stable performance even in high humidity environments, unaffected by condensation or humid air. With a water repellency rate of up to 98%, it effectively resists corrosion from humid environments, preventing condensation, mold, and other problems.

🌡️ Stable Thermal Insulation Performance

With a thermal conductivity of ≤0.043 W/(m·K), it possesses high thermal resistance and a low linear expansion rate, ensuring long-lasting and stable thermal insulation performance. Excellent insulation performance helps maintain a constant temperature and humidity environment in cleanrooms, effectively reducing operational energy consumption.

♻️ Non-corrosive and Environmentally Friendly

Magnesium oxysulfate board uses magnesium as a binder, contains no chloride ions, and is non-corrosive to steel. It will not corrode aluminum, rivets, or steel. No harmful gases are released during product manufacturing and use, making it a green and environmentally friendly new building material.

🔇 Excellent Sound Insulation Performance

Sound insulation performance reaches 232dB, with good sealing performance, effectively solving sound insulation problems in various building spaces.

📏 Excellent Flatness

Due to the low coefficient of thermal expansion and contraction of the core material, combined with one-time cutting using an imported electronic precision saw, the overall flatness error is controlled within 0.1mm. The panels have excellent flatness, strong adhesion between the steel plate and the core material, and high overall strength.

Application Scenarios

With its comprehensive advantages such as A1-level fire resistance, lightweight and high strength, moisture resistance, water resistance, thermal insulation, and sound insulation, magnesium oxysulfide sandwich panel is widely used in the following fields:

Pharmaceutical Industry: Pharmaceutical GMP workshops, biological laboratories, medical operating rooms;
