Product Description

Device Name: Electrophoresis equipment
Equipment introduction: Electrophoresis is carried out by anodic electrophoresis [AED] and cathodic electrophoresis [CED]; electrophoresis anode coating or electrophoresis cathode coating is selected according to the metal activity of the workpiece. Cathodic electrophoresis is generally used for inactive metals.
The electrophoresis tank of the main body of the apparatus generally has two kinds of ship shape and rectangular shape; the ship shape is used for continuous pass electrophoresis, and the rectangle is used for intermittent up and down lifting electrophoresis. In order to avoid the precipitation of the paint liquid caused by the dead angle, the corner of the bottom of the groove adopts a circular arc shape. The large tank is made of epoxy resin or unsaturated polyester fiberglass or medium and small tank engineering plastics (PP or PVC). With overflow tank.
Grouped equipment:
1. Temperature regulating device: During the electrophoresis process, heat will be continuously generated, and the temperature of the paint liquid is controlled at *7 °C**8 °C through the heat exchanger and the heat and heat unit. Because the bath temperature is low, the film thickness is lowered and the appearance of the film is rough. The high bath temperature causes the film to thicken, and the surface is imprinted, and the bath is aged.
2. Washing device (RO): After the workpiece is electrophoresed, the floating paint is adhered to the surface of the coating film, and it must be washed with pure water through multiple stages. Therefore, industrial pure water units must be equipped, and the ratio of electrophoretic paint must also be pure water.
3. Ultrafiltration device (UF): (1) remove various impurity ions in the paint solution and purify the bath. (2) The ultrafiltrate is used for cleaning the workpiece after electrophoresis. (3) Recover most of the electrophoretic paint.
4. Select a qualified rectified power supply to ensure automatic fluctuation and steady flow, the fluctuation amplitude is less than 5%.
The conveyor chain uses a C-type hook to prevent dust from falling into the electrophoresis bath and the product during chain operation.
Technical parameters: coating line design speed **4 m / min,
The film thickness is about *0μm. The product can be tested for neutral salt spray after cathodic electrophoresis for *******0 hours. The product can be tested for neutral salt spray after anodic electrophoresis for ******0 hours.
