Applications:
PEI polyethyleneimine and derivatives have good effects in electroplating brighteners such as zinc, copper, and silver.
This article takes galvanized brightener as an example to introduce the addition effect of PEI.
Galvanizing Overview Galvanizing can be found in two methods: acid galvanizing and alkaline galvanizing. The choice of electroplating solution, the type and shape of iron, the appearance and characteristics of the finished product, the toxicity of the electroplating solution, and the processing cost are all factors that need to be considered.
Furthermore, brighteners are required in zincates and acidic baths. PEI can be chelated with Zn, which after electrolysis, moves on the iron surface to form a fine film, which helps to achieve better brightness. Effect of PEI Addition Effect of PEI in zincate bath (composition of electroplating solution) ZnO: 10g/l, NaOH: 110g/l Brightener: PEI 2g/l, p-methoxybenzaldehyde: 0.2g/l (electroplating conditions) Use a Hull electroplating tester under 2AX5min (test results)
