What is PVD for Stainless Steel Sinks?
PVD (Physical Vapor Deposition) is a technology that forms a thin film coating on the surface of stainless steel kitchen sinks. This coating not only adds to the aesthetic appeal of the sink, but also improves its wear and corrosion resistance.
How is a PVD Surface Formed?
The process of PVD surface formation mainly includes the following steps:
Vacuum Environment Preparation: The stainless steel kitchen sink is placed in a high vacuum environment to ensure that the coating material can effectively adhere to the substrate.
Material Evaporation: A specific coating material (e.g., titanium, zirconium, chromium, etc.) is selected and heated to its evaporation point to evaporate the material into a gaseous state.
Ionization and Acceleration: The evaporated material is ionized and accelerated by an electric field towards the surface of the stainless steel sink.
Deposition: The ionized material is deposited on the surface of the stainless steel to form a uniform and dense coating.
Advantages of the PVD Process
Wear Resistance: The PVD coating significantly increases the hardness of the sink surface, enhancing wear resistance.
Corrosion Resistance: PVD coatings provide good corrosion resistance and extend the service life of the sink.
Decorative: PVD coating can provide a variety of colors and surface effects, such as gold, black, rainbow colors, etc., to enhance the aesthetics of the product.
Environmentally Friendly: PVD process is more environmentally friendly compared to the traditional electroplating process as no harmful chemicals are used.
Strong Adhesion: PVD coating has high adhesion and is not easy to come off.
Disadvantages of the PVD Process
Higher Cost: Due to the complexity of the equipment and process, the cost of PVD coating is higher.
Strict Process Requirements: It needs to be carried out under high vacuum conditions and is difficult to operate.
Difficulty in Maintenance: Once the PVD coating is damaged, the repair is more complicated and requires specialized equipment and technology.
How to Test the Quality of PVD?
Visual Inspection: Observe whether the coating is uniform, with or without color difference, spots, or bubbles and other defects.
Hardness Test: Use a hardness tester to test the hardness of the coating to ensure that it meets the standard requirements.
Adhesion Test: Perform a scratch test or peel test to check the adhesion of the coating.
Corrosion Resistance Test: Test the corrosion resistance of the coating through a salt spray test and other methods.
Abrasion Resistance Test: Simulate the actual use environment and conduct an abrasion test on the coating to evaluate its abrasion resistance.
How to Maintain the PVD Surface Stainless Steel Sink in Daily Life?
Avoid Hard Object Collision: Try to avoid hitting the surface of the sink with hard objects to prevent damage to the coating.
Cleaning Attention: Use a soft cloth and neutral cleaner to clean the sink, avoid using acidic or alkaline strong cleaners.
Prevent Chemical Corrosion: Avoid prolonged contact with strong chemicals such as bleach and ammonia.
Regular Maintenance: Regularly maintain with a professional maintenance agent to keep the coating glossy and protective properties.
