Effect of additives for alkaline zinc plating on the properties of solution
Abstract:In zincate solution, the additive is a decisive factor of the solution Performance. This project mainly to study five different additives effect on the performance of the zincate solution. Based on the amount of a single type of additive study confirm the role of various additives and the optimal dosage: FJ-1 for the refiner can refine crystal, the best dosage 10.0mL/L; FJ-2 as brighteners, can improve the coating bright performance, optimal dosage 1.0mL/L; FJ-3 supplement agent, optimal dosage 5.0mL/L; FJ-4 to take the agent, you can raise the bath dispersing ability and coverage, optimal dosage 7.5mL/L; PUB also have to walk as well as refinement and optimum dosage 6.0mL/L. When used in conjunction with five kinds of additives, while adding zincate galvanized base fluid: FJ-1 was 10.0mL/L, FJ-2 was 1.0mL/L, FJ-3 was 5.0mL/L, FJ-4 was 7.5mL/L, PUB was 6.0mL/L, a wide current density range of the zincate solution, temperature insensitive, resulting bright coating appearance, good bath dispersibility, good coverage.
Kewyords: alkaline zinc plating; additive; brightness; throwing power; coveraging power.
