COLOR AND HARD ANODIZING PROCESS FOR APPLICATION ON METAL PLATES OF HAIR STRAIGHTENING AND MODELING MANUAL EQUIPMENT

摘要

Refers to the present invention for improvement applied in hard and color anodization process, especially used in metallic elements of equipment normally employed to straighten and modeling hairs, also traditionally known as "hair straightener", "board" or "straightening plate" and it can be optionally applied also in other type of equipment of same kind used to produce curly hair. These equipments have two heating units; each of the heating units comprises, in turn, an electric resistance which heats a flat metal plate, component which gets into direct contact with hair during the straightening process, being the concerned improvement wherein the contact face of each one of the flat metallic plates of straightening and modeling equipment, has a coating in the shape of a layer formed by aluminum oxide and ceramic material (Al2O3), being this layer colored and sealed and which its hardened layer thickness is at least 45 microns. For the equipment of type known as "modeler" the referred layer aggregated to material is on the tubular body base, the same coating is yet incorporated on the inner face of the compression device in clip shape; this flat metal plate was improved by using the color hard anodizing process.
