Epoxy powder is a kind of thermosetting, non-toxic paint, after curing the formation of high molecular weight cross-linked structure coating, with excellent chemical corrosion resistance and high mechanical properties, especially the best wear resistance and adhesion. The coating is 100% solid, no solvent, no pollution, powder utilization rate of up to more than 95%, is a high quality anti-corrosion coating for buried steel pipeline. The three layer PE process using epoxy powder coating and adhesive backing PE polyethylene winding or coated, steel pipe anticorrosion technology is widely used at home and abroad, gas oil, and the oil is currently the west east gas pipeline anticorrosion technology of gas supply, the city water supply.
The coating is a new anticorrosive layer developed in the last 30 years, which is applied in the electrostatic spraying process. The coating has the advantages of simple operation, no pollution, good resistance to impact and bending resistance, high temperature resistance, and has been widely used in foreign countries.
Powder coating is not solvent containing 100% solid powder coatings, with no solvent, no pollution, saving energy and resources, reduce labor intensity and high mechanical strength. They feature film storage stability at room temperature, the friction electrostatic spraying, spraying (thermosetting method), or fluidized bed dipping (thermoplastic method). Re heating baking melting and solidification, to form a flat permanent film light, to achieve the decoration and corrosion.
According to experts, epoxy powder coating is the most important, which is one of the best performance, with excellent adhesion and flexibility, and excellent corrosion resistance and anticorrosion life, widely favored by the market and welcome. With the rapid development of outdoor building materials, household appliances, as well as the increasing of various vehicles, the increasing demand for paint products, both the quantity and variety of performance requirements, put forward a lot of paint industry to solve, and raw material production plant project. Because of its high coating efficiency and no pollution, powder coatings are still of great significance to develop new epoxy powder coatings, especially new epoxy resins. Expert introduction, new epoxy varieties for powder coatings, as well as the status quo and problems in the application process
