Glass fiber reinforced plastic (FRP) fans refers to the fan made of glass fiber reinforced plastic (FRP) material. Its appearance and size are exactly the same as that of steel fan. Only the shell and impeller are made of glass fiber reinforced plastic (FRP).
FRP fans are suitable for ventilation and exhaust in office buildings, shopping malls, theaters, hospitals, factories, workshops, basements and other places. The gas to be transported should not contain viscous substances, and the temperature of the gas should not be greater than 80℃, and the mass of the media should not be greater than 150mg/M3.
If there is no organic gas and acid and base gas, the general carbon steel fan is used. If there are the above two kinds of gas, the FRP fan is used.
FRP fan has the following advantages:
- Relatively high density
The relative density is between 1.5~2.0, only 1/4~1/5 of carbon steel, but the tensile strength is close to, or even more than carbon steel, and the specific strength can be compared with high alloy steel. Therefore, in aviation, rockets, space vehicles, high-pressure vessels and in other need to reduce the weight of the product application, it has excellent results. The tensile, bending and compressive strength of some epoxy FRP can reach more than 400Mpa. The density, strength and specific strength of some materials.
- Good corrosion resistance.
FRP is a good corrosion resistant material, to the atmosphere, water and the general concentration of acid, alkali, salt and a variety of oils and solvents have good resistance. Has been applied to all aspects of chemical corrosion protection, is replacing carbon steel, stainless steel, wood, non-ferrous metals and so on.
- Good electrical performance
It is an excellent insulating material used to make insulators. High frequency can still protect good dielectric property.
- Good thermal performance
The thermal conductivity of FRP is low, 1.25~1.67kJ/ (m·h·K) at room temperature, only 1/100~1/1000 metal, is an excellent insulation material. It is an ideal material for thermal protection and ablative resistance at instantaneous ultra-high temperature.
- Good designability
According to the needs, flexible design of a variety of structural products, to meet the requirements of use, can make the product has a good integrity.
- Excellent workmanship
The process is simple, can be formed once, the economic effect is outstanding, especially for the shape of complex, not easy to form a small number of products, more prominent its technological superiority. The surface treatment is simple, can imitate many kinds of material effect.
