A Roll-to-Roll (R2R) Dip Coater is a classic "immersion" coating system where the substrate (web) is passed through a liquid bath to be coated on both sides simultaneously. While Slot-Die and Doctor Blade coating are preferred for primary electrodes, dip coating is a vital process in your research for functionalizing separators and fabricating ion-exchange membranes where full saturation or double-sided application is required.

In a R2R dip coater, the foil or membrane is guided into a reservoir (dip tank) by a series of rollers. (1) Immersion: The web travels down into the coating fluid. (2) Pick-up: As it emerges vertically, a liquid film adheres to both sides of the substrate. (3) Metering (The Landau-Levich Regime): The final thickness is determined primarily by the withdrawal speed and the viscosity of the fluid. (4) Doctoring (Optional): Many R2R dip coaters include "Air Knives" or "Squeeze Rollers" at the exit of the tank to blow off or press out excess liquid to achieve a specific target thickness.

Part Number
  • ESMR2RDC (ESM-R2RDC)
Power
  • AC220V±10%, single phase, 50/60Hz, 3000 W
General Features
  • Roller width: 300 mm 
  • Loading substrate width: Max. 280 mm
  • Coating width: Max. 280 mm
  • Mechanical coating speed: 0.05-0.75m/min (the real coating speed depends on the slurry properties and dry oven length/temperature)
  • The general design drawing is shown below:

         

Unwinding/Winding Parts
  • Roller diameter: 3", mechanical expansion for tightening the loading roll substrate and collection cardboard. 
  • Max. winding/unwinding roll diameter: 300 mm 
  • Alignment Sensors were installed and aligning position resolution could be ±0.3-0.5 mm. 
Dip Coating Parts
  • Slurry Container Size: 0.3 L (0.7 L and 2.7 L can be supplied upon request)
  • Slurry Viscosity: 50-500 cP (Recommended).
  • The peristaltic pump EABSFPP2L can be supplied as slurry feeder for the dip coating. 

                   
Metering Wire Rod
  • After dip coating, the wet coating film will go through the metering wire rods and obtain desirable thickness. 
  • The standard wire rod (ESMAWRW300) is D10 mm, effective coating length is 300 mm, and groove 

           

Heating Oven Features
  • Heating mode: IR heating (carbon fiber), 2 kW.
  • Heating chamber length: 0.5 m
  • Heating temperature: Max.150℃
  • Ventilation: centrifugal blower, air flow: 330m³/h (adjustable), 3" aluminum pipe

Tension Control System
  • Tension range: 10-60 N (resolution is ±3 N), which is controlled by swing roller system.
  • For low-tension substrate coating (eg: separator and membrane), the specially designed low tension version is highly recommended since its lowest tension can be down to 5 N.
Gas Compressor
  • A gas compressor (EUQOFGC) is needed to provide 60-80 psi for pneumatic operation.
Certification
  • CE certified
  • UL and CSA certification is available upon request at extra cost
Dimension
  • L980 * W750 * H1420 mm
Weight
  • ~580 kg
