What Is Surface Treatment and Why It Matters for Valves
Surface treatment is a method that modifies a material’s outer layer to enhance its function. For industrial items like valves, surface treatment boosts protection against rust, wear, and chemicals. It also improves sealing and helps coatings bond better.
Knowing what is surface treatment is essential in valve production. It ensures valves last longer and perform reliably in harsh settings. Surface treatment is a standard practice. It enhances both performance and appearance. This ensures valves remain dependable in various applications.
Sandblasting uses swift abrasive particles to clean a valve’s outer layer. It removes grime, corrosion, and old paint. This creates a textured surface. The texture helps coatings adhere firmly. Sandblasting is often the first step in the surface treatment process. It is especially common for steel valves. The method ensures steady surface quality in large-scale production. It is widely used because it is quick and efficient.
Pickling is a surface treatment that uses acids, such as hydrochloric or sulfuric acid. It removes oxides and rust from the valve. The valve is dipped in a pickling tank. Then, it is rinsed with water. This process cleans deeply into the metal. It leaves the surface smooth and glossy.
The pickling surface treatment process is very useful for stainless steel valves. It readies the surface for further treatments or painting. It provides a clean finish needed before coating or welding.
Phosphating involves placing the valve in a chemical solution. This forms a phosphate coating. The coating resists rust and helps paint stick to the metal. This surface treatment technology creates a robust layer. It works well for valves exposed to moisture or outdoor conditions. Many industries use it to prevent paint from peeling. It also delays rust formation on the metal.
Electroplating uses electric current to apply a thin metal layer to the valve. Common metals include zinc, nickel, and chromium. This surface treatment process improves the valve’s look and lifespan. It also increases toughness and makes cleaning easier.
Spray coating applies paint or powder to the valve’s surface with a spray tool. It forms a strong outer layer after heat curing. Spray coating is popular for anti-rust and high-temperature paints. It is a low-cost, effective surface treatment method.
Before any surface treatment, the valve must be spotless. Oil, dust, and rust need to be removed. If not, the treatment may fail.
During the surface treatment process, factors like time, temperature, and current require close attention.
After treatment, the valve is cleaned, dried, and packed carefully. Leftover chemicals can damage the product.
