Description
PVC powder coated wire mesh is manufactured using hot-dip galvanized or low-carbon steel wire with a wire diameter ranging from 1.0 to 5.0 mm. A powder coating process is used during production, with PVC powder applied electrostatically and then cured at 160-200°C to form a dense coating. This process offers a smooth, flat surface with a thickness of 0.1-0.3mm and a choice of colors. It is suitable for applications such as building fencing, industrial protection, and agricultural breeding. The powder coating thickness of PVC powder coated wire mesh generally ranges from 50μm to 200μm, or approximately 2mm. Coating thickness varies depending on the application requirements.
Production Process of PVC Powder Coated Wire Mesh
The production process of PVC powder coated wire mesh directly impacts its performance characteristics. To ensure every customer enjoys high-quality wire mesh, we maintain strict production standards, meticulously examining every detail and strictly adhering to the following procedures:
Preparation: Preparation is crucial. The appropriate material and wire diameter can be determined in advance. If corrosion resistance is critical, galvanizing may be required.
Welding: The mesh is welded to the desired mesh size and shape to create the initial shape. Resistance welding or arc welding is recommended to ensure strong welds and a stable structure.
Surface treatment: The welding process may leave residual oil, rust, and dust on the surface, which must be cleaned to ensure the powder is smooth and resistant to corrosion. The final coating has excellent adhesion to the steel wire surface.
Powder coating: This is the most critical step in the entire PVC powder coated wire mesh production process. PVC powder is sprayed through a spray gun and evenly adhered to the wire mesh surface through electrostatic attraction. It's important to maintain an appropriate distance and angle between the spray gun and the mesh to ensure a uniform coating thickness.
High-temperature curing: The mesh is placed in a high-temperature curing oven and cured at temperatures between 160-200°C. The specific time depends on the coating thickness and powder properties, forming a dense, uniform coating.
Cooling and setting: After removal from the curing oven, the mesh is cooled naturally or by forced cooling to lower the temperature. The coating solidifies and sets, completing the production of a beautiful PVC powder coated wire mesh.
Why choose PVC powder coated wire mesh?
Many users may wonder: Why choose PVC powder coated wire mesh? What are the advantages of PVC powder coating during use? When discussing PVC, we inevitably think of its corrosion resistance. Let's take a closer look:
● Corrosion Resistance: PVC coating effectively blocks corrosive media such as acids, alkalis, and salts. Whether used daily or in industrially polluted areas, it has a very impressive service life, typically up to 20 years.
● Tensile Strength: This is, of course, a characteristic of the steel wire itself. High-quality hot-dip galvanized steel wire boasts a tensile strength of ≥500N/mm², making it suitable for load-bearing applications such as building fencing and slope protection.
Let's expand on the performance of PVC powder coated wire mesh. When used outdoors, it can withstand external impacts and operate in temperatures ranging from -30°C to 60°C. It's also waterproof and moisture-resistant, allowing it to be used in humid environments. However, it does have limitations. For example, it isn't heat-resistant and will soften and deform in environments above 80°C, so this is something you should be aware of.
Maintenance and Care of PVC Powder Coated Wire Mesh
PVC powder coated wire mesh requires long-term maintenance. Check the surface for looseness, deformation, or peeling coating. If the surface is dirty, use a soft brush or neutral detergent. Avoid damaging the PVC coating with hard objects. If the coating is damaged and the metal substrate is exposed, polish it immediately and spray it with PVC powder or anti-rust paint of the same color to prevent further damage to the PVC powder coated wire mesh. If you encounter any problems during use, please contact customer service for the best solution.
