The principle of LCP nickel plating is to form a metallization layer on the surface of plastic, giving the plastic surface metallic properties

Nickel plating is commonly used in industries such as hardware, electronics, and automotive,Nickel plating is a method of depositing a layer of nickel on metals or certain non metals through electrolysis or chemical methods, which can be applied to localized electroplating of corroded parts,Electroplated nickel platingIt has high stability, excellent polishing performance, relatively high hardness, and a wide range of applications, and can be used as a protective decorative coating. However, after nickel plating, sometimes there may be problems such as workpiece oxidation discoloration and water stains returning to rust. How can this be solved?

firstThe reason for the discoloration of workpieces and the occurrence of water stains and rusting is the phenomenon of a certain porosity between the microstructures of the nickel plating layer, which can easily attack the nickel layer and the substrate metal below it, reducing the corrosion resistance of the coating. A recommended solution to this problem is to use a nickel surface anti discoloration protective agent, an aqueous system, non-toxic and odorless,Forming a hydrophobic film layer, quickly dehydrating, leaving no water stains, the protective film does not change the appearance gloss and weldability, has an isolation effect, and there will be no fingerprints left at the touch of the hand, effectively delaying the corrosion behavior of corrosive liquids on the workpiece.

This article will introduce the principle, preparation, properties, and applications of LCP electroplating nickel.

 1、 Principle

   LCP electroplated nickel platingThe principle is to form a metallic layer on the surface of plastic, giving the plastic surface metallic properties. Electroplating is a process of depositing metal ions on a metal surface. Its principle is to use electrochemical reactions to reduce ionized metal to metal atoms on the electrode surface and deposit them on the electrode surface. The process of LCP electroplating nickel can be divided into surface treatment, electrolyte preparation, electrolysis process, cleaning, and drying steps. During the surface treatment process, it is necessary to clean, remove dirt, oil, and oxidize the plastic surface to improve its roughness and surface energy, and increase the adhesion between metal and plastic surfaces. In the process of electrolyte preparation, it is necessary to select appropriate electrolytes, additives, and electrolysis conditions to control the speed, uniformity, and quality stability of the electrolysis process. During the electrolysis process, it is necessary to place the processed plastic as a cathode into the electrolytic cell, and at the same time, deposit metal ions from the electrolyte on the surface of the plastic through electrolysis reaction, forming a layer of metallization. During the cleaning and drying process, it is necessary to clean the surface of the treated metallized plastic, remove electrolyte and impurities, and dry and stabilize its surface through drying and other methods.

2、 Preparation

The preparation process of LCP electroplating nickel requires strict control of electrolysis conditions and parameters such as electrolyte composition and concentration to ensure the quality and uniformity of the metallization layer. Generally speaking, the preparation process of LCP electroplating nickel includes the following steps:

1. Surface treatment: Clean, remove dirt, oil, and oxidize the plastic surface that needs to be treated to improve surface roughness and surface energy.
2. Electrolyte preparation: Select appropriate parameters such as electrolyte, additives, and concentration based on different plastic materials and electrolysis conditions to ensure the speed, uniformity, and quality stability of the electrolysis process.
3. Electrolysis process: Place the processed plastic as the cathode into the electrolytic cell, and deposit metal ions from the electrolyte on the surface of the plastic through electrolysis reaction, forming a layer of metallization.

4. Cleaning and drying: Clean and remove electrolyte and impurities from the surface of the treated metallized plastic, and dry and stabilize its surface through drying and other methods.
   

3、 Performance

The performance of LCP nickel plating depends on factors such as the thickness and uniformity of the plastic substrate and metal nickel layer. Generally speaking,LCP electroplated nickel platingThe metal nickel layer has good wear resistance, corrosion resistance, oxidation resistance, high temperature resistance, conductivity and other properties, which can effectively improve the durability and aesthetics of plastics. The thickness of the nickel metal layer is generally between 5-20 microns and can be adjusted according to different application requirements. The uniformity and adhesion of the metallic nickel layer are also important indicators for evaluating the quality of LCP nickel plating.

LCP nickel plating has been widely used in the fields of automobiles, electronics, home appliances, toys, and more. In the automotive field, nickel electroplating can be used for components such as car shells, wheels, and decorative parts to improve the aesthetics and durability of cars. In the field of electronics, nickel electroplating can be used for components such as phone cases, computer cases, monitor frames, etc., to improve the appearance quality and durability of electronic devices. In the field of home appliances, nickel electroplating can be used for components such as refrigerator door handles and microwave knobs to improve the aesthetics and durability of home appliances. In the field of toys, nickel electroplating can be used for metal toys, models, figurines and other components to improve the texture and durability of toys.

In summary, LCP electroplating nickel is a high-performance surface treatment technology that can form a uniform, dense, wear-resistant, and corrosion-resistant metal nickel layer on the surface of plastics, improving the durability and aesthetics of plastics.
