Pretreatment System
Pretreatment is a crucial step in the powder coating process, ensuring optimal adhesion and corrosion resistance of the coating to the substrate. At Zhanyao , we offer top-of-the-line pretreatment equipment designed to meet the diverse needs of our customers. Our pretreatment solutions are available in two primary types: spray type and dip tank type.
Pretreatment System
Spray Type Pretreatment Equipment:
Our spray type pretreatment equipment is designed to apply pretreatment chemicals evenly and efficiently onto the surface of the workpiece. This equipment utilizes spray nozzles to disperse the pretreatment solution, covering the entire surface area with a fine mist. It offers flexibility in adjusting parameters such as spray pressure, flow rate, and chemical concentration to achieve optimal results for different substrates and coating requirements.
Degreasing - Rinsing -Surface Activation- Conversion Coating
Advantage:
1. Spray type pretreatment equipment can be Utilized with automated conveyor systems to enhance production efficiency.
2. Above the pretreatment equipment, there is a ventilation device to prevent the accumulation of hazardous gases.
3. The shed body, cylinder block, and spray pipe are constructed from stainless steel, with meticulous welding ensuring a service life of over 15 years.
Dip Tank Type Pretreatment Equipment:
Our dip tank type pretreatment equipment immerses the workpieces into a tank filled with pretreatment chemicals. The workpieces are submerged in the solution for a specified duration, allowing for thorough and consistent coating of the surface. It ensures complete coverage of all surfaces, including recessed areas and crevices, resulting in enhanced adhesion and corrosion protection.
The material commonly used for dip tank pretreatment systems is typically corrosion-resistant materials such as stainless steel or polypropylene, (PP). These materials are chosen for their durability, chemical resistance, and ability to withstand the harsh conditions of pretreatment processes involving corrosive chemicals.
