What is the copper plating process?

Insulated bottle is one of the commonly used items in our daily life, which can keep hot water or cold water warm, so that we can enjoy hot water or cold water at any time when we go out or office. The insulation and anti-corrosion performance of the insulated bottle depends largely on the coating on its inner wall. Among them, copper plating process is a commonly used coating process, below we will learn more about the copper plating process of insulated bottle.

I. What is copper plating process?

Copper plating is a process of plating copper layer on the surface of the object, the copper plating layer is pink, soft, easy to polish, and has good ductility. Nowadays, the commonly used copper plating process methods are acid copper plating, sulfate copper plating, ethylenediamine copper plating, cyanide copper plating and so on.

In the electroplating method, the surface of the object needs to be cleaned first, and then the object is immersed in an electrolyte containing copper ions, which are reduced to copper and deposited on the surface of the object through the action of electric current to form a copper layer. The thickness of the electroplated copper layer can be adjusted as needed, generally between a few microns and tens of microns.

In the chemical plating method, the surface of the object needs to be cleaned first, and then the chemical liquid containing copper ions is applied to the surface of the object, and the copper ions are reduced to copper deposited on the surface of the object through a chemical reaction to form a copper layer. The thickness of the chemical copper plating layer can be adjusted according to the need, generally between a few microns and tens of microns.

II. Why do insulated bottles need copper plating?

The advantages of copper plating include:

1.Aesthetics: Copper plating can make the surface of the object with a metallic texture and luster, increasing the aesthetics and added value of the product.

2.Corrosion resistance: The copper layer has good corrosion resistance, can protect the surface of the object from corrosion and oxidation.

3. Thermal insulation: Copper has good reflectivity, and copper plating can effectively form a thermal insulation layer in the inner liner of stainless steel bottles, which can reduce the heat loss through radiation and achieve high thermal insulation performance and long thermal insulation time.

III. What are the application areas of copper plating process?

The inner wall of the insulated water bottle is the part that directly contacts the beverage. If there are uneven places, it will not only affect the insulation effect, but also easy to breed bacteria, which is not conducive to cleaning and hygiene. Therefore, the copper plating technology of insulated water bottle requires that the inner wall of insulated water bottle have a smooth and flat surface without obvious bumps or imperfections.

The inner wall of the insulated water bottle copper plating layer should also be uniform, dense, strong adhesion. A uniform copper plating layer can ensure that the heat inside the thermal bottle is evenly distributed, improve the thermal insulation effect, and a dense copper plating layer can prevent the beverage from penetrating into the inner wall of the thermal water bottle, protect the stainless steel material, and prolong the service life of the thermal bottle.

The copper plating technology of thermal bottles also requires the appearance of the thermal bottle to be bright and beautiful.Copper plating layer should have a certain brightness and luster, making the insulated bottle look more high-end atmosphere. At the same time, the copper plating layer should also have a certain degree of abrasion resistance and corrosion resistance, which can maintain a long time beautiful.

The requirements for copper plating technology of thermal bottles also involve the selection and control of copper plating processes. Generally speaking, the copper plating process of insulated bottles can choose electroplating, chemical plating or vacuum plating and other methods. It is very important to choose the appropriate copper plating method according to the specific requirements and material characteristics of the thermal bottle. In addition, the control of copper plating process is also the key to ensure the quality of insulated bottle. This includes the control of the copper plating solution, copper plating time, and temperature, etc., to ensure the quality stability of the thermal bottle.

In conclusion, copper plating is an important inner coating process with a wide range of applications and important application value. Manufacturers need to choose the appropriate copper plating method and technology according to the needs and requirements of the product to ensure the quality and stability of the product. In the future, with the continuous progress of science and technology and people’s pursuit of high quality of life, copper plating technology will continue to develop and innovate, bringing more opportunities and challenges to various fields.
