Detailed Explanation of Vacuum Coating Technology for Colored Decorative Stainless Steel Sheets

For example, when we want to coat a stainless - steel plate with a golden color, we will evaporate and ionize the titanium - metal target in a vacuum environment. These charged titanium ions, under the action of the electric field, are evenly deposited on the surface of the stainless - steel plate, combine with the surface atoms of the stainless - steel plate, and form a golden - colored film, thus endowing the stainless - steel plate with a golden appearance.

1. Vacuum Pumping: Evacuate the impurity gases in the coating equipment to make the vacuum degree reach 10⁻²Pa - 10⁻⁴Pa, creating a pure environment with almost no interference from other gases for the subsequent coating process. It's like painting in a clean room; without dust interference, the painting can be more perfect.

2. Filling with Inert Gases: Fill with inert gases such as nitrogen and argon. These inert gases play an important role in the subsequent process. They participate in gas discharge and help to achieve the evaporation and ionization of the target material.

3. Ion Bombardment Cleaning: Generate ions from the filled gases through high - voltage direct current and bombard the surface of the substrate with ions. This step is like giving the surface of the stainless - steel plate a deep - cleaning. It can not only remove tiny impurities on the surface but also greatly enhance the adhesion strength of the film layer, laying a good foundation for subsequent coating and coloring, eliminating the phenomenon of titanium dropping, and making the plate surface clean and bright.

4. Evaporation Coating: Connect the AC power supply of the evaporation source. The evaporation - material particles melt and evaporate, enter the glow - discharge region and are ionized. The positively charged evaporation - material ions, attracted by the cathode, rush towards the workpiece together with the argon ions. When the number of evaporation - material ions deposited on the surface of the workpiece exceeds the number of sputtered - off ions, they gradually accumulate to form a color - coating layer firmly adhered to the surface of the workpiece.

5. Vent and Unload: After completing the above steps, vent the gas, open the furnace door, and take out the coated Colored decorative stainless steel sheets. So far, the entire finished - product operation is completed.

1. Color and Texture Diversity: From classic gold, silver, and black to fashionable rose gold, champagne gold, sapphire blue, and even natural textures such as imitation wood grain and imitation stone grain, it can almost meet the needs of all design styles. Designers can choose appropriate colors and textures according to different project requirements to create a unique atmosphere for the building space.

2. Strong Adhesion: There is a very good bonding force between the film layer and the stainless - steel substrate, and it is not easy to fall off. This makes the Colored decorative stainless steel sheets maintain integrity even after certain friction and collisions during subsequent use, greatly extending the service life of the product.

3. Good Weather Resistance: It can maintain stable performance under different environmental conditions. Whether it is exposed to sunlight, wind, rain, or in a humid environment, it is not easy to fade or deform and always maintains a bright appearance.

4. Enhanced Corrosion and Wear Resistance: To a certain extent, it enhances the corrosion - resistance performance that stainless steel originally has and also improves its wear - resistance ability, enabling the Colored decorative stainless steel sheets to perform well in various application scenarios.

1. Stainless - Steel Sheets: The surface of stainless - steel sheets is of uniform thickness and relatively easy to clean. The main task is to remove the protective film and surface glue, impurities, etc. However, if the sheets are placed for too long, the protective film may deteriorate, which may lead to difficulties in removing the surface glue later and affect the surface cleanliness. Therefore, pay attention during storage and use.

2. Stainless - Steel Components: The cleaning of stainless - steel components is more complex. Not only the obvious surfaces need to be cleaned, but also the polishing wax, glue, rust spots, dust, welding slag, and other impurities in the inconspicuous gaps such as welding, folding, and bending corners need to be removed thoroughly with cleaning agents. In particular, some substances that are difficult to remove, such as polishing wax, salt, rosin, sand, wood, glue, and plastic hidden in stainless - steel pipes and invisible places, will seriously affect the quality of vacuum coating, resulting in abnormal colors or color fading. Therefore, stainless - steel component manufacturers should try to avoid these substances being hidden in the components during the production process.

1. Corrosion - Resistance Issues: Although the vacuum - plated PVD film has certain corrosion - resistance, it is still difficult to resist the contact with strong corrosive substances such as acids and alkalis. During daily maintenance, try not to choose cleaning agents containing strong acids or alkalis or with strong decontamination ability, such as toilet cleaners, paint strippers, and metal cleaners. You can choose industrial alcohol and gently wipe with a soft cotton cloth. If there are dirt on the surface, choose weak - acid or weak - alkali solvents for treatment. In addition, if it is exposed to a harsh environment for a long time or in contact with corrosive liquids for a long time, the PVD film layer is also prone to problems such as peeling, such as in environments with fluorine (such as swimming pools), high salt content (such as seawater), and high - temperature and high - humidity (such as steam).

2. Use of Anti - fingerprint Light Oil: More and more customers choose to spray a layer of transparent anti - fingerprint clear oil on the stainless - steel products with colored PVD film layers. The effect is very obvious. There are no fingerprint marks when touched by hand, it is easy to clean, and it can also increase the wear - resistance and corrosion - resistance functions. However, its disadvantages cannot be ignored. The color of the oil - sprayed product is different from that of the non - oil - sprayed one. The processing requirements are high, the cost is not low, it will also affect the metallic texture of the product, and there are problems such as aging. Therefore, consider carefully before using it.

3. Subsequent Processing Issues: The PVD film layer has a good bonding force with the substrate, and the product can be subjected to simple subsequent mechanical processing, such as cutting, folding, bending, and shearing. However, welding has a great impact on the PVD film layer. The instant high temperature will cause the film layer to peel off and change color. Therefore, for stainless - steel products that need welding and coloring, it is best to make the components first and then color them. Do not use the materials with PVD film layers to process and make products.

1. High - end Residential Buildings: It is often used for exterior - wall decoration, balcony railings, interior partitions, etc. For example, in exterior - wall decoration, the unique color and luster of Colored decorative stainless steel sheets can make the residence stand out among many buildings and show a high - end and elegant quality; in interior partitions, it can divide the space and add a sense of fashion and art to the interior.

2. Commercial Complexes: With its unique texture and luster, it has become an iconic element in places such as brand stores, shopping centers, and hotel lobbies. In brand stores, Colored decorative stainless steel sheets can be used for the production of display racks, counters, etc., attracting the attention of customers and enhancing the brand image; in hotel lobbies, it can create a luxurious and elegant atmosphere, leaving a deep impression on customers.

3. Cultural Landmarks, Transportation Hubs and Other Public Buildings: With its excellent durability and artistic expressiveness, it has become an indispensable part of the urban skyline. In cultural landmark buildings, Colored decorative stainless steel sheets can show the local cultural characteristics and artistic styles through unique shapes and colors; in transportation hubs such as airports and high - speed railway stations, it can not only play a decorative role but also withstand the wear and various environmental factors brought by a large number of people.
