Method for manufacturing aluminum mirror without being coated with protective paint
The aluminium mirror claims to aluminize mirror again, is usually processed by vacuum plating unit . Existing aluminium mirror adopts float glass as former, successively through cleaning polishing, high vacuum metal deposition aluminize, work program such as the corrosion-resistant leaching paint of first pass and oven dry, second time waterproof stiffened leaching paint and oven dry and making. Because it does not consume precious metal, production cost is lower, thereby is used widely at aspects such as decoration and light reflecting materials.
But because aluminium is a kind of active metal, the aluminium film that evaporation forms is very thin fine and close inadequately again, very easy oxidation, and one or two layer of protective paint of necessary coating could life-time service.The aluminium mirror can not use protective paint in some special environments, as is in the reflector under the high temperature, the glass Mosaic that inorganic adhesive need be used in the back side etc. So existing aluminium mirror making method can not satisfy people's production and living needs.
This is a preferred implementation of the present products; be noted that for those skilled in the art; under the prerequisite that does not break away from the principle of the instructions, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
