FBE layer of raw materials is a solid epoxy resin agent and various additives by mixing, grinding processed, and is a thermosetting material. Coating, the first steel tube heated to 220-230℃ , the adsorption spraying electrostatic spraying the surface of the pipe; heated and cooled melt adhesive curing. Single-layer FBE coating thickness of 300-500um; layer FBE thickness control in 450-1000um. FBE coating has excellent adhesive strength, high insulation resistance, soil stress, anti-aging, anti-cathode stripping, temperature, resistance to bacteria and cathodic protection current is small (only 1-5uA/㎡). And many other advantages. But there are also poor performance. But there are also poor performance against mechanical impact, high water absorption and other.
