how zinc pots are usually damaged

hot dip galvanizing kettle

The surface adhesion of the substrate is not cleaned and tidy: This type of leakage plating will spread to the lower or upper surface of the strip, generally showing aperiodic small patches. Reason: The emulsified oil on the surface of the substrate is uneven, or there is residual rolling oil on the surface of the […]

What are the classifications of the nickel plating process

nickel plating

1) Dark Nickel. In addition to individual use as a functional coating, mainly used as a protective decorative coating primer to replace the copper plating process to increase the bonding force of the coating. 2) Semi-bright nickel. In the dark nickel plating solution, add a small amount of sulfur-free additives with good leveling ability, you can […]

Such advantages of hot-dip galvanizing

hot dip galvanizing

With the development of industry, hot dip galvanizing design has been used in many fields, the advantages of hot dip galvanizing are the long anti-corrosion life, adapt to a wide range of environments has been a very popular anti-corrosion treatment method. It is widely used in electric power towers, communication towers, railroads, highway guardrails, street […]

What is the case of using auxiliary anode or cathode in electroplating

auxiliary anode

1.What is an auxiliary anode? In the process of electroplating various products and parts, some complex shapes and tubular parts that need to be plated evenly or have plating in the inner hole, etc. should add another anode in the low current density area to make the current distributed evenly as much as possible, and this […]

What are the technical characteristics of QPQ

QPQ furnace

1、Good wear resistance In the QPQ process, the metal material reacts with the salt bath liquid at a working temperature of 570±10℃ to form a dense compound layer of excellent quality on the metal surface. The compound consists entirely of epsilon iron nitride, which is highly effective in improving the hardness and denseness of the […]

What is “QPQ”

QPQ furnace

“QPQ” is the abbreviation of “Quench-Polish-Quench” in English. The original meaning is quenching – polishing -quenching. It is after the salt bath compound treatment, in order to reduce the surface roughness of the workpiece, the surface of the workpiece can be polished once, and then in the salt bath for oxidation, which is very necessary […]

What are the factors affecting the service life of a galvanizing pot

galvanizing pot

The service life of a zinc pot is closely related to the material of the steel plate, the type of fuel, the form of structure, the zinc capacity, the choice of heat load, the galvanizing process and the way of operation management, the balance of production volume and the type of plated parts. The service […]
