Pre-treatment is an essential step in the coating process, ensuring the workpiece surface achieves the required cleanliness and adhesion for superior coating quality, enhanced durability, and improved corrosion resistance. The ultimate goal of pretreatment is to remove surface contaminants such as grease, dirt, moisture, oxides, and rust, laying the foundation for the adhesion and corrosion resistance of subsequent coatings. Even with high-performance coatings, improperly treated surfaces are prone to problems such as blistering, peeling, and rusting. Therefore, pretreatment plays a decisive role in the coating process. Depending on customer needs, the main steps include:
Removes oil and dust using hot water and detergents.
Eliminates oxides and rust, activating the metal surface.
Enhances surface roughness, fatigue resistance, and hardness.
Forms a protective chemical layer to improve adhesion and corrosion resistance.
Removes chemical residues in every main steps.
Adds a protective layer to avoid oxidation after rinsing.
Liquid electrostatic spray equipment uses an electrostatic field to evenly attract charged paint particles onto workpiece surfaces, offering precise, efficient, and eco-friendly coating application.
Powder coating employs high-voltage electrostatic fields to adhere negatively charged powder particles to positively charged surfaces, ensuring a uniform and durable finish.
ED coating uses an electric field to deposit paint particles onto submerged workpieces. This technology is commonly used in the preparation of protective coatings for metal surfaces to improve rust resistance and form a strong film through electrophoresis to enhance the product’s corrosion resistance. It has the advantages of high efficiency, good uniformity, and environmental friendliness.
Pipes face various environmental challenges during manufacturing and use, such as corrosion, wear, and oxidation. Therefore, different coating technologies are required to improve their performance and extend their service life.
Coil coating equipment is mainly used for surface treatment of steel coils. The coating is evenly sprayed onto the surface of the steel coil and cured by baking to form a durable coating. The coating process can provide the surface with excellent corrosion resistance, acid resistance, and rust prevention properties.
Ovens are indispensable equipment in industrial production, used to heat coated workpieces to cure the coating. Different types of curing ovens have different characteristics in terms of heating methods, energy efficiency, and applicable scope.
