METHOD OF ENVELOPING METAL HOLLOWS WITH POLYETHYLENE

摘要

The metal hollow is provided with an electrostatically applied base layer of an epoxy resin, upon which an ethylene copolymer powder is electrostatically applied possibly with the inclusion of epoxy resin and possibly in several layers of varying relative consistency. After each powder application step, surface heating is applied to melt the respective powder layer. The final coating of polyethylene is applied either electrostatically or through a suitable extrusion process. Particular grain size distribution and powder consistency patterns are suggested.
