IMPROVED ROUGHENED METAL SURFACES AND METHODS OF PRODUCTION THEREOF

摘要

A reflective area 38 of a metal workpiece 20. A designated 24 surface 22 of a workpiece 20 is coated with an average thickness of 58mum to 72mum of liquid bonding media 26 and untreated glass particles 28 with sizes in the range of 160mum to 600mum are adhered to bonding media 26 which cures to form a connective layer adhering particles 28 to designated area 24 thereby rendering it reflective to incident light. Methods of producing reflective area 38 are further disclosed. The disclosed reflected areas are roughened and further serve to reduce adherence of handbills.
