After the color of the copper door, because more aesthetic, and its use, watch the value is relatively high, and thus by the people generally welcomed. Colored copper in addition to a beautiful appearance, as decoration, but also can improve the wear resistance of copper and corrosion resistance, therefore, Copper coloring technology developed a new field of surface treatment.
1, the treatment process: degreasing rust in addition to oxide - washing - pickling polishing - washing - and - washing - coloring - washing - drying and other post-processing
2, pickling polishing recommended use of copper pickling polishing liquid for processing. The purpose is to make the brass surface shiny.
3, the goods for the working fluid, the workpiece soaked in the goods, Copper about 2 minutes brass surface that becomes black cyan, according to the experimental results. Soaking time is 20-25 minutes, the surface color change the best quality, can get better anti-rust performance. Copper The workpiece can be repeated soaking, increase the color layer thickness, can obtain satisfactory results.
4, if you want to achieve bronze, after the above steps, can be used sandpaper friction, in order to achieve the desired results. We can use some dry towels to clean, but can not use some of the paint will contain damage to the maintenance of the chemical composition of the detergent to clean. Copper In the handling of objects to avoid touching the copper barrier, destroy its maintenance layer, try not to let the copper barrier directly washed by the rain, causing rusty situation.
Copper fence is made of electrolytic plate, will be sprayed on the above and some of the same color and copper door paint, it looks and copper door almost, so called copper guardrail. Because the copper guardrail fundamental material problems, maintenance is very important, Copper and spit it above the paint off, inside the electrolytic plate will be exposed, and if the electrolytic plate encountered in the air where the oxidation of oxygen on the situation The appearance of the situation of copper, destroyed the elegance of the copper barrier. Maintenance of the copper fence is very important on the one hand is to ensure the integrity of the above paint, Copper do not appear bump hit the situation.
At the same time to follow the installation of the balustrade scale: railing should be a solid, durable material manufacturing, and can withstand the load scale rules of the degree of load; Copper railings height should not be less than 1.05m, high-level construction of the railing height should be properly improved, 1.20m; railing from the ground or roof 0.10m height should not be left blank.
