Abstract
A method is provided for producing metallic platelets. By determining the ratio of the diameter of the metal source to the thickness of the metallic platelet and the workability of the metal source, a high quality metallic platelet can be developed. According to this method, the platelets that are produced can be used in such applications as building and construction materials for improved weather-resistance, heat-reflection/management, anti-fouling resistance and architectural appearance.
Claims19
A process for making a platelet, said process comprising rolling a metal piece in one-step to form the platelet, wherein:
- D=diameter of the metal piece
- t=thickness of the platelet
- and 1≦D/t≦15.
8 A process for making a platelet comprising the process of claim 1 and further comprising using a secondary operation to alter the appearance of the platelet.
A process according to claim 8, wherein said secondary operation comprises using an acidic, a basic or a solvent solution.
A process according to claim 8, wherein said secondary operation comprises using a post-heat treatment under an atmosphere containing one or more substances selected from the group consisting of air, hydrogen, nitrogen and inert gases.
A process according to claim 8, wherein said secondary operation comprises electroplating another metal onto the surface of the platelet.
A process according claim 8, wherein said secondary operation comprises coating the metallic platelet with an organic or organic coating.
A method for making a metallic platelet comprising:
- a. determining a desired thickness of a metallic platelet;
- b. selecting a metal piece based on said desired thickness of said metallic platelet;
- and
- c. forming said metallic platelet from said metal piece.
