| Fusion bonded epoxy powder coating (FBE/2FBE) is a new anticorrosion coating which developed for nearly 30 years. There has two kinds: single layer and double layers. Single-layer FBE coating adopts special fusion bonded epoxy powder coating as film forming material, take the electrostatic spraying coating epoxy powder coating process, form the coating layer at one time. This is epoxy powder is one kind of thermosetting coatings, it is made of solid epoxy resin, curing agent and various additives. We need do sand blasting and medium frequency preheating to the pipe, before spray painting, then using electrostatic spraying method in the application of epoxy powder coating steel tube of heating surface, molten adhesive on steel pipe surface, solidified to form coating. Generally speaking, FBE coating form the coating layer at one time.FBE coating has many advantages, such as :strong adhesive to the steel, good completeness of the film, resistance o the cathodic disbonding, resistance to the soil stress, stand wear and tear, the coating operation is simple, pollution-free, the coating has good ability to counter bending and impact and high temperature resistance, which made it widely used in a lot of countries.FBE coating can be used as the outside coating of steel buried pipeline or submarine pipeline at the -30°C----+100°C environment. Standard: SY/T0315-2005，QCNPC 38-2002,QSY-XQ9-2003 etc. It mainly adopts the following produce process : |
