      Copper powder (also known as gold powder) is a kind of metal with a scaly structure, which can be floated in a binder, exhibits golden luster and has pigment properties, which is made of copper-zinc alloy as a raw material through special mechanical processing and surface chemical treatment. pigment. Due to its brilliant metallic luster, gravure printing has a wide range of applications in plastics, high-grade pictorials, high-end packaging, cigarette shells, and securities printing. Therefore, higher requirements are imposed on the main technical indexes such as gloss, metallic feeling, water surface coverage, product particle size and distribution of copper powder. The copper powder produced by the traditional process has been difficult to meet modern requirements. Therefore, the copper powder is deeply drilled. Research and development have important practical significance.

Application areas:

     Copper gold powder is mainly used in crafts, paints, inks, coatings, printing, silk screen printing, printing, leather, wallpaper, automotive paints, etc. 
The high-content copper commonly used in the determination of copper is still the old iodometric method, its potassium iodide The dosage is large, the cost is high, and the time is much, and the newly developed photometric method is not suitable for the determination of high content copper due to the problem of copper color developer, so it is necessary to research and develop a new color developer. The author tried to control the pH value with acetic acid-sodium acetate buffer solution, and used ethylenediaminetetraacetic acid disodium salt (EDTA) as a color developer to determine the high content of copper in copper powder, while using EDTA to mask elements such as zinc and aluminum. Eliminate its interference. Cu^2+ and EDTA form a blue complex with a molar ratio of 1:1. The complex has a larger absorption wavelength of 2=730 nm, a molar absorptivity of ε=88.9, and a copper ion content of 12-24 mg/50 mL. There is a good linear relationship in the range, and the linear regression equation is A=0.0354+0.02317c
