Description

Technical Field

[0001] The utility model relates to the technical field of air duct plates, in particular to a moisture-proof and corrosion-resistant composite air duct. Background Art

[0002] The air duct is a piping device used for air delivery and distribution. When making stainless steel air ducts, apply sealant on the bite seams, rivet seams, four corners of flange flanging and gaps to ensure sealing. Before applying sealant, remove surface dust and oil stains. According to the production process of the air duct, the air duct is classified by material. It can be divided into metal air ducts, composite air ducts and polymer air ducts. They are classified according to their cross-sectional shape and material, including composite air ducts and inorganic air ducts.

[0003] Composite air ducts are represented by rubber-plastic composite air ducts. They are made of rubber-plastic composite insulation materials and can completely replace traditional air ducts, air valves, air outlets, static pressure boxes, and rubber-plastic composite air duct devices of insulation materials in air-conditioning air supply and outlet devices. They not only have the exemplary characteristics of energy saving and environmental protection, but also their design directly affects the air supply effect and the cooling and heating effects of the entire space. In large shopping malls, composite air ducts can effectively transport the cold and hot air generated by the air-conditioning device to various areas, ensuring that the temperature in the mall is uniform and stable. The hotel's kitchen ventilation device uses composite air ducts, which can withstand the erosion of high temperature, high humidity and oil smoke, and maintain good ventilation effects.

[0004] Moisture-proof and anti-corrosion composite air duct is a ventilation duct with excellent performance. It is mainly used in various places with high requirements on air quality and pipeline durability. The outer protective layer is made of corrosion-resistant materials to effectively resist the erosion of the external environment. The middle insulation layer is made of materials with good thermal insulation performance to reduce the heat exchange between the air in the pipeline and the external environment and improve energy efficiency.

The vents will loosen and move, which will change the direction of the airflow and affect the ventilation effect.
