单独High-pressure anti-corrosion centrifugal fan refers to a high-pressure centrifugal fan that adopts corrosion-resistant and anti-corrosion materials or has been treated by anti-corrosion technology. All high-pressure centrifugal fans can be made of anti-corrosion type. The main materials are divided into four categories, stainless steel, plastic, fiberglass, steel lining Or steel lining plastic, which kind of material should be determined according to the actual working conditions.
1. The material of glass fiber reinforced plastic anti-corrosion high-pressure centrifugal fan is glass fiber reinforced plastic (FRP), also known as GRP, that is, fiber-reinforced plastic, which generally refers to the use of glass fiber to reinforce unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics that use glass fiber or its products as reinforcement materials are called glass fiber reinforced plastics, or glass fiber reinforced plastics. Due to the different types of resin used, it is known as polyester glass fiber reinforced plastic, epoxy glass fiber reinforced plastic, and phenolic glass fiber reinforced plastic. Light and hard, non-conductive, high mechanical strength, less recycling, corrosion resistance, but the maximum temperature resistance does not exceed 80 degrees, the impeller needs to use steel-lined glass steel
2. The material of the plastic anti-corrosion high-pressure centrifugal fan is plastic, generally using PVC pp and other materials, polyvinyl chloride. This is the most widely used meaning of PVC. Rigid PVC is one of the most widely used plastic materials. PVC material is an amorphous material. , Like the FRP fan, the maximum temperature resistance is 80 degrees.
3. Stainless steel anti-corrosion high-pressure centrifugal fan, stainless steel (Stainless Steel) refers to steel that is resistant to weak corrosive media such as air, steam, water, etc., and chemically erosive return media such as acids, alkalis, and salts. Corrosion resistance is not as good as the above two, but high temperature resistance and high strength.
