Rishbin Slitting Machine Electrolysis Board Introduction

The Rishbin slitting machine is widely used in slitting and slitting of sheet metal. Electrolytic plates are one of them. What is electrolytic plate? Many people are not very clear. As a well-known manufacturer of electrolysis plate slitters, Rishbin will give you a brief introduction of electrolytic plate knowledge.
Electrolytic plates, also known as electrogalvanized plates, are processes that use electrolysis to form a uniform, dense, well-integrated layer of deposited metal or alloy on the surface of the part. Compared to other metals, zinc is a relatively inexpensive and easily coated metal and is a low-value corrosion-resistant plating. It is widely used to protect steel parts, especially to prevent atmospheric corrosion, but also for decoration. Plating techniques include slot plating (or rack plating), barrel plating (suitable for small parts), automatic plating and continuous plating (suitable for wire, strip).
The electrolytic plate production process is cumbersome, and it needs to be rolled by a tandem cold rolling mill, and then after annealing by the CAPL unit, it enters the electrogalvanizing unit. Finally, after the surface cleaning plating, according to different uses, can be phosphating, passivation, oil and fingerprint, alloying and other treatment, the final product is the electrolytic plate. For its related mechanical properties, refer to the corresponding substrate.
In the end, what kinds of electrolytic plates are there? The domestic electrolytic plates currently known to Rishbin are mainly divided into four major categories, which are mainly classified according to electroplating solutions, as follows:
Cyanide galvanizing
Since (CN) is highly toxic, environmental protection places stringent restrictions on the use of cyanide in electrogalvanizing and continues to promote the development of reduced cyanide and substituted cyanide galvanizing bath systems, requiring the use of a low cyanide (microcyanide) aftelectroplate liquid. After electroplating with this process, the product quality is good, especially color plating, and the color remains good after passivation.
Zinc plating:
This process evolved from cyanide galvanizing. With this process, the lattice structure of the coating is columnar, and it has good corrosion resistance. Besides, it is suitable for color galvanization.
Note: After the product out of the tank → washing → light (nitric acid + hydrochloric acid) → washing → passivation → washing → washing → drying → drying → aging treatment (80 ~ 90 °C in the oven).
Chloride zinc plating
This process is widely used in the electroplating industry, accounting for up to 40%. After passivation (blue and white) can be zinc chromium (equivalent to chrome plating), especially after the addition of water-soluble varnish, it is difficult for laymen to recognize whether it is galvanized or chrome-plated. This process is suitable for white passivation (blue-white, silver-white).
Sulfate galvanizing
This process is suitable for continuous plating (wire, strip, simple and large parts), and is inexpensive.
