AI Technical Summary

Problems solved by technology

After reviewing the literature and visiting the factory, it is found that the determination of the main salt content in the electroplating solution, especially the determination of zinc, still uses an older process, and potassium cyanide, a highly toxic substance, is used
And the measurement process is relatively complicated. Due to various factors, the workers in the factory cannot timely grasp the content of the main salt in the plating solution, and some small factories are not equipped with laboratories, so the operation is quite inconvenient.

Abstract

The invention discloses a rapid on-line analysis kit, which comprises a small Erlenmeyer bottle, a 100mL reagent bottle, a 10mL colorimetric tube, a 10mL syringe, a 1mL syringe, a 2mL small reagent tube, a 1mL small reagent tube, a colorimetric card, a rapid Look-up table and several reagents, the reagents include pH=10 buffer solution, ammonium viurate indicator, 0.05mol / LEDTA standard solution, 10% barium chloride solution, phenolphthalein indicator, 0.5mol / L hydrochloric acid standard solution, 100g / L ammonium persulfate solution, etc. With this kit, the main components in the alkaline zinc-nickel alloy electroplating solution can be measured online at any time, without affecting the electroplating production process, and without large-scale repeated tests. It is widely used in electroplating factories with imperfect production conditions and laboratory equipment Foreground, the most important thing is that this kit does not contain any cyanide-containing compounds, which is of great significance for maintaining the ecological environment and improving the protection of workers' lives.

Description

technical field [0001] The invention relates to a kit, in particular to a rapid on-line analysis kit. Background technique [0002] Zinc-nickel alloy electroplating is a steel anode type protective coating that has emerged in the past 20 years. Zinc-nickel alloys usually refer to low-nickel-content alloys with a nickel content of less than 20%. This type of alloy coating not only has corrosion resistance 7 to 10 times higher than that of galvanized coatings, but also has good paintability, weldability and formability. , so it is widely used in automobiles, aerospace, light industry, household appliances and other steel protection; in addition, zinc-nickel alloys also have the advantage of low hydrogen embrittlement, can replace cadmium coatings in the aviation industry, and have great development prospects. In the zinc-nickel alloy electroplating process, the main components of the electroplating solution need to be analyzed on-line. Cyanide has been used in it for more tha...
