FBE/2FBE epoxy powder anticorrosive elbow: production and processing range φDN80—φDN1400

Fused epoxy powder outer coating (FBE/2FBE) is a new type of anti-corrosion coating developed in the past 30 years. FBE coating has two types: single layer and double layer. The so-called FBE coating generally refers to a single-layer fusion bonded epoxy coating. The single-layer FBE coating uses special fusion bonded epoxy powder coating as the film-forming material. The epoxy powder coating is applied by electrostatic spraying process to form a film at one time. This epoxy powder coating is a thermosetting coating, which is processed by mixing and pulverizing solid epoxy resin, curing agent and various additives. The elbow is shot blasting and intermediate frequency preheating before spraying, and then the epoxy powder coating is sprayed on the surface of the heated elbow by electrostatic spraying method, and it is melt-bonded on the surface of the elbow and solidified to form a coating. FBE coating is generally a one-time film formation structure. FBE coating has strong adhesion to steel, good film integrity, resistance to cathodic stripping, soil stress and abrasion resistance, simple coating operation, no pollution, good impact and bending resistance of the coating, high temperature resistance, etc. The advantages have been widely used abroad. FBE coating can be used for the external anti-corrosion of steel buried pipelines or underwater pipeline facilities whose working temperature is -30~100 degrees Celsius.
