Brass rods are easily oxidized when exposed to the air for a long time, so is there any good measure to prevent the oxidation of brass rods?
1 Pair of brass rods are sealed and packaged, and two bags of desiccant are added at the same time. 2 The wooden shaft and the wooden box board are dried. 3. The air dryer discharges water every day. The branch factory formulates a system and implements the responsibility to the person. The charter captain of the maintenance section discharges water every day, and the technical unit conducts spot checks from time to time. 4 When transporting from a low temperature area to an area with high temperature and high humidity, do not immediately open the sealed package of the sealed brass row. After taking perfect anti-corrosion measures, the corrosion amount of brass row is greatly reduced. If the process discipline is strictly observed, the corrosion problem of brass row can basically be solved. 5 The main reason for the corrosion of brass row is that it is exposed to water or damp during storage and transportation. Water in the compressed air will cause the aluminum foil to corrode during the day. Brass row The electrolytic coloring of brass row has good decorative properties, so it is widely used at home and abroad, especially in the production of surface treatment of architectural brass rods. At present, the main process is to use tin-nickel mixed salt electrolytic coloring, and the color of the produced products is mainly champagne color. Compared with single nickel salt coloring, the color of tin-nickel mixed salt electrolytic coloring products is bright and full; the main problems are: There is color difference in the product, and the unreasonable extrusion process and oxidation coloring process in the production process of aluminum profiles will cause color difference in the product.
The influence of extrusion process on the oxidation coloring of brass row is mainly the influence of die design, extrusion temperature of brass row, extrusion speed, cooling method, etc. on the surface state and uniformity of the extruded profile. The mold design should be able to fully knead the feed material, otherwise, bright (dark) band defects may easily appear, and color separation may appear on the same profile; at the same time, the state of the mold and the extrusion pattern on the surface of the profile also affect the oxidation coloring. Extrusion temperature, speed, cooling method and cooling time are different, so that the profile structure is not uniform, and color difference will also occur.
