The polyethylene covering is a layer of polymer from 500 microns thick which fits a surface tightly and interferes with activization of corrosion reactions. For drawing a polyethylene covering the special equipment is used.
The galvanized metal product is warmed in the camera of preliminary heating to 320 °C. After that the warmed product is dipped into a bathtub with polyethylene polymeric structure of small fraction (99% of polyethylene and 1% of powder paint). Particles of dye (pigment) and polyethylene stick to the warmed metal, forming a dense bed. Before sending to the polymerization camera the product is mechanically stirred up to get rid of excess powder.
Process of polymerization or "roasting" happens at a temperature of 210 °C - 220 °C. Polyethylene powder on a product is melted off, forming a dense bed owing to what the continuous covering turns out.
After the polymerization camera the product is cooled and is ready to use.
The polyethylene covering creates thicker layer, than powder and polymeric owing to what the metal product is steadier against aggressive conditions of the environment. It maintains temperature condition from -60 °C to +90 °C. Besides, at deformation of a product this covering stretches in the place of a bend whereas paint bursts and showered forming the square for hit of corrosion substances at metal.
