High temperature resistant centrifugal fan materials usually refer to the materials of the housing, centrifugal impeller, and air inlet. To cope with different application natural environments, the raw materials used in the parts at different locations are different, so the auxiliary materials that are willing to be used as the centrifugal wind mechanism usually must have the necessary performance indicators. I will give you a detailed introduction to the different raw materials used in the manufacture of centrifugal fans.
1. Carbon steel is mostly used, which is the key material for general high temperature resistant centrifugal fans. Among many types of carbon steel, Q235B is used more. This type of carbon steel is not only easy to produce and process, but also low in price. It is suitable for centrifugal fans with most materials at room temperature without smoke, dust and erosion. The popular fan models 9-19, 4-72, 9-26, etc. are all manufactured with this type of material.
2. Stainless steel plate is the first of the common auxiliary materials, but I think it does not only refer to this material, but one type including more than 100 kinds of actual materials. The key is austenite, ferrite, metallographic structure, Duplex stainless steel, etc., usually anti-corrosion fans are made of this kind of raw material, perhaps the price is undoubtedly higher than carbon steel.
3. There is also this kind of common auxiliary material that is glass fiber reinforced plastic, which is very good for making centrifugal fans. Because this kind of raw material has excellent anti-corrosion characteristics, it is resistant to erosion by various acids, alkalis and salts. In the petrochemical industry, many vapor solutions use glass fiber reinforced plastics high temperature resistant centrifugal fans to avoid corrosion and increase the service life.
4. The usual auxiliary material is the PP plastic that people often say, that is to say this kind of thermoplastic resin made from pe polymer. Because its compressive strength is lower than that of FRP, I think the application range is relatively small, but sometimes it must be made of this kind of raw materials.
According to the above detailed introduction, people can grasp that the characteristics of high temperature resistant centrifugal fans manufactured by different materials are different. When you are carrying out the purchase work, you should choose the relative ones according to the specific production and manufacturing natural environment. Of centrifugal fans. Only in that way can the material of the centrifugal fan give full play to the required application advantages in the relative natural environment.
