The magnesia duct is mainly made of magnesia cement, alkali-resistant fiber cloth and inorganic adhesives by modern process technology rolling. It has the advantages of light weight, sound insulation, long service life, etc., and is a new generation of energy-saving and environmentally friendly green product.

[0003] Magnesium alloy, as a lightweight, high-strength and corrosion-resistant material, is widely used in the manufacture of ducts in air conditioners and ventilation systems. Its lightweight characteristic helps to reduce the self-weight of the system and installation costs. At the same time, it has good corrosion resistance and is suitable for applications in humid and corrosive environments. The design of duct connectors plays a key role in the stability and sealing of the system. High-quality connectors need to have good mechanical strength and connection stability to ensure the safe operation of the duct system. At the same time, the design of the connectors also needs to consider the convenience of installation and disassembly to reduce construction costs and improve the maintenance efficiency of the system. Sealing technology is also of great significance in the connection device of magnesia ducts. The selection of sealing materials and the implementation of sealing processes directly affect the sealing performance of the system, ensure that the gas inside the duct system does not leak, and ensure the normal operation of the system.
