What is the surface treatment of doors and windows
Surface treatment of doors and windows refers to the application of various technologies and coatings to improve their appearance, durability, and performance. These treatments not only enhance the visual appeal of doors and windows, but also protect them from environmental factors such as corrosion, weathering, and scratches, ensuring that doors and windows can undergo changes over time and be completely new.
Surface Treatment Description
Paint Coating: This is one of the most common surface treatments for doors and windows. Paint coatings provide a decorative finish and protect the surface from scratches and corrosion. They can be applied in various colors and finishes to match the desired aesthetics.
Powder Coating: similar to paint coating, powder coating involves applying a dry powder to the surface of the doors and windows. The powder is then heated to form a smooth and durable finish. This treatment is often used for aluminum doors and windows as it provides excellent corrosion resistance.
Anodizing: This treatment is commonly used for aluminum doors and windows. Anodizing involves passing an electric current through the aluminum surface, creating a protective oxide layer. This layer improves the corrosion resistance and durability of the aluminum.
Electrophoretic Coating (E-Coating): This process involves immersing the doors and windows in an electrophoretic bath, where a paint-like coating is deposited on the surface. The resulting finish is uniform and provides good corrosion resistance.
Wood Grain Transfer Coating: This treatment is used to create a wooden texture on doors and windows, providing a natural and elegant appearance. It involves transferring a wood grain pattern onto the surface using special techniques.
The specific process of surface treatment for doors and windows
The process of surface treatment for doors and windows is complex.The following is the processing flow for different surface treatments of doors and windows.
Surface Treatment Process
powder coating
💎Process: The profiles are colored using a brush particle seasoning method; Powder spraying, also known as electrostatic spraying, is a physical phenomenon based on electrophoresis that causes atomized paint particles to carry negative charges on a high-voltage electric field, and under the action of the electrostatic field, they are directed to flow to the surface of positively charged profiles, thereby adhering to form a solid thin film.
💎 Features: Multiple color options and strong weather resistance
💎Market demand: The equipment, process, and operability of powder spraying are stronger, and the customization of colors is more suitable for home decoration doors and windows. There are many spraying factories of various sizes, making it the most commonly used surface treatment method for profiles in the retail market.
anodic oxidation
💎Process: Put the cleaned profiles into a pool filled with color seasonings, soak them, and then bake them at high temperature; The profile with a glossiness similar to that of an Apple phone case appears;
The process of placing aluminum or aluminum alloy products as anodes in an electrolyte solution and utilizing electrolysis to create aluminum oxide thin films on their surface profiles.
💎 Features: Smooth surface, strong metallic texture, but with fewer colors
💎Market demand: High equipment and process requirements, only large aluminum factories can do it. The quality is very guaranteed, often seen in the surface treatment of large quantities of profiles, and the proportion of appearance in the home decoration retail market is not high.
electrophoresis
💎Process: Electrophoresis and anodizing are similar processes, but after baking, the surface needs to be coated with paint again, mainly for preservation;
The anodized product is an anode, with aluminum or stainless steel as the cathode, placed in a transparent acrylic resin solution. Under the action of an external electric field, negatively charged coating particles move towards the product, resulting in a layer of adhesive paint film on its surface profile.
💎 Features: Excellent weather resistance, smooth surface, shiny and gorgeous appearance, but the paint film is relatively easy to scratch.
💎Market demand: Similar to the retail market in Jiyang, there is almost no demand.
Wood grain transfer printing
💎Process: Apply a layer of penetrating film with wood grain transfer pattern on the surface of qualified aluminum material through powder electrostatic spraying, then vacuum and completely cover the surface of the profile with the penetrating film. Heat the film to transfer the ink penetrating on the film and penetrate into the powder coating, achieving the appearance effect of wood grain.
💎 Features: The wood grain appearance may be favored by specific groups of people, but the weather resistance of the color is slightly poor
💎Market Demand: making it more suitable for color decoration of indoor profiles; The side that rushes towards the outside is not recommended.
