Magnesium Oxysulfide Sandwich Panel

The Machine - madeMagnesium Oxysulfide Sandwich Panel is a high - performance building material with excellent comprehensive properties, which is widely used in the construction industry. The following is a professional introduction to it:

Structure and Materials

• Surface Layer: The surface layers of the panel are usually made of high - quality galvanized or color - coated steel sheets. These steel sheets are 0.376 - 0.5 mm thick generally. The color coating not only endows the panel with rich colors to meet different aesthetic requirements, but also provides good corrosion resistance, protecting the panel from environmental erosion and prolonging its service life.

• Core Layer: The core layer is made of magnesium oxysulfide material. Sulfur - oxygen - magnesium is a kind of magnesium - based cementitious material with stable performance, which is composed of magnesium oxide, sulfuric acid and other substances. It has the advantages of low density, good thermal insulation, fire resistance and sound insulation.

Production Process

• Material Preparation: High - quality galvanized or color - coated steel coils and sulfur - oxygen - magnesium raw materials are prepared. The magnesium oxysulfide raw materials need to be accurately proportioned and mixed to ensure the stability of the material performance.

• Panel Assembly: Through a high - speed continuous automatic molding machine, the galvanized or color - coated steel sheets and the magnesium oxysulfide core material are heated and pressed together. The high - strength adhesive is used to bond the two layers firmly to form a sandwich structure.

• Finishing: After the panel is formed, it will go through processes such as trimming, slotting and blanking to make its size and shape meet the design requirements. Finally, a PVC protective film may be pasted on the surface to protect the panel from scratches and damage during transportation and installation.

Advantages

• Fire Resistance: The sulfur - oxygen - magnesium core material is non - combustible, and the board has a fire resistance time of 1-3 hours. It can effectively prevent the spread of fire and ensure the safety of buildings and personnel in the event of a fire.

• Thermal Insulation: With a low thermal conductivity, the panel has good thermal insulation performance. It can reduce heat transfer between the inside and outside of the building, helping to maintain a stable indoor temperature and reduce energy consumption for heating and cooling.

• Sound Insulation: The magnesium oxysulfide core has certain elasticity and airtightness, which can effectively block the transmission of sound and create a quiet indoor environment.

• Waterproof and Moisture - proof: The panel has a low water absorption rate, generally ≤ 0.8%. Even when exposed to water, the magnesium oxysulfide core will not deform irregularly or undergo chemical reactions, ensuring the stability of the panel in humid environments.

• High Bonding Strength: The high - strength adhesive is used between the core material and the steel sheet, which makes the bonding strength between them high and effectively avoids the phenomenon of delamination.

Applications

• Industrial Buildings: It is widely used in the walls and roofs of factories and warehouses. Its fire resistance, thermal insulation and other properties can meet the requirements of industrial production environments, and can also improve the energy efficiency and safety of buildings.

• Commercial Buildings: In shopping malls, office buildings and other commercial buildings, the panel can be used for interior and exterior decoration, as well as partition walls and ceilings. Its rich colors and good performance can enhance the overall quality and comfort of the building.

• Clean Rooms: Due to its dust - proof, antibacterial and other characteristics, it is very suitable for use in clean rooms in the electronics, pharmaceutical, food and other industries, helping to maintain a clean and sterile environment.

• Residential Buildings: It can be used in the exterior walls and interior partitions of residential buildings, providing good thermal insulation, sound insulation and fire protection functions, and improving the living comfort and safety of residents.
