The main material used in composite air duct is composite air duct board, so the choice of composite air duct board is different, which will lead to different characteristics, quality and price of composite air duct. Therefore, some composite air duct processing factories will choose better quality , air duct plates with relatively low cost, this is something that composite air duct manufacturers intuitively need to consider. Air duct manufacturers also need to consider the characteristics of composite air duct plates. So what characteristics should be considered when choosing composite air duct plates?
First: fire protection characteristics
In fact, the composite air duct used in the project is not only used as ventilation duct , but also as a fire smoke exhaust duct. Whether it is ventilation ducts or fire smoke exhaust ducts, they all need the most basic feature, which is fire protection.
Second: waterproof and moisture-proof properties
As an air duct, it is mainly used for ventilation and smoke exhaust, so the air duct is often in a water environment. Therefore, the duct board selected must be waterproof and moisture-proof.
Third: anti-corrosion properties
Composite air ducts are used as fire smoke exhaust ducts, so the smoke in the air ducts contains a large number of corrosive components, so the ventilation ducts need to have anti-corrosion properties.
Fourth: environmental protection features
Nowadays, building materials advocate environmental protection, so the composite air duct board selected for composite air duct is environmentally friendly, non-toxic and tasteless, and has no radioactive substances ..
Considering the above characteristics of air duct boards, Class A fire-resistant and flame-retardant boards are the best choice for composite air duct boards. The characteristics of Class A fire-proof and flame-retardant boards are Class A flame retardant, formaldehyde E1, waterproof and moisture-proof, light weight and earthquake-resistant. Excellent strength, insect-proof and mildew-proof, thermal insulation, sound-absorbing and sound-insulating, non-toxic, tasteless, and no radioactive substances.
