MSK-AFA-200 is a Roll-to-Roll coater with 6 optional coating heads or head combinations for film coating with a small footprint for materials research labs. This system integrates the functions/ features of reeling in & out, slurry feeder, coating blade, baking oven, and final electrode winding (reeling in). It can automatically coat electrode sheets up to 160mm in width and 500 meters in length. For Roll to Roll Coater Service, please fill out and submit the Roll to Roll Coating Service Request FormNote: upgraded to 4 coating heads option since Nov. 15, 2021 SPECIFICATIONS: Power 208 - 240VAC, 50/60Hz, Single phase ~4 KW 6 Types of Coating Heads Optional(1) Doctor Blade Coating(2) Reverse Comma Blade (Transforming)(3) Micro-Gravure Coating (4) Slot Die Coating(5) Slot Die + Doctor Blade Coating(6) Slot Die + Reverse Comma Blade Coating Please select the option bars to choose the coating head/combination(1) Doctor Blade Coating, MSK-AFA-E200 (2) Reverse Comma Blade (Transforming), MSK-AFA-EI200 (3) Micro-Gravure Coating (MSK-AFA-MG200) (4) Slot Die Coating (MSK-AFA-SD200) (5) Slot Die + Doctor Blade Coating (MSK-AFA-DC200) (6) Slot Die + Reverse Comma Blade Coating (MSK-AFA-DE200) Coating Width 160 mm Maximum (roller width is 200 mm and a maximum substrate width of 180 mm is acceptable) Coating thickness Reverse Comma Blade / Doctor Blade Coating: 30~200μm, depending on different slurry viscosity Slot Die Coating: 5 - 200 micron, which is decided by slurry viscosity, feeding speed, and the gap between the slot die and the substrate. it is made of stainless steel (SUS630) for coating thickness from 5μm to 300μm. Various shims can realize the coating width. Micro-Gravure Coating: 1~50 um (dried film) The precise digital thickness gauge (EQ-DTG) can be used to measure the electrode sheet thickness. It is an optional item and should be purchased at an extra cost. Coating Speed 0 - 200 mm/minute (actually, the maximum mechanical speed of the motor is 1 m/min), the coating speed is normally limited by the drying efficiency. Heating Heating method: Forced convection hot air (IR + UV heating is available upon request) Convection chamber: 500 mm length Max. Drying Temperature: 130°C Temperature Accuracy: ±1°C Temperature uniformity: ±3-5°C Customized design of dual heating chambers is also available Reeling/Unreeling Reeling/Unreeling shaft: 75mm (ID), which is a mechanical expanding shaft Reeling/Unreeling Roller: 200mm OD Max. Coating Length Depending on the coating and substrate thickness. Reverse Comma Blade / Doctor Blade Coating: 10um thick foil with 100um coating can get 500 meters of electrode length coated per run Slot Die Coating: 30 mm width and 0.2 mm thickness, the coating length can reach 15 meters for a 100 ml pump Micro-Gravure Coating: 2~3um ( dried film ) Slurry Feeding (Optional) As for doctor blade, reverse comma blade, and microgravure, a peristaltic pump of MSK-155 with 2L volume can be considered: As for the slot die, syringe pump of MSK-151-L500, and the screw pump of MSK-156 can be considered for continuous and intermittent coating, respectively: Compliance CE Certified NRTL (UL61010) or CSA certification is available upon request at extra cost. Application Notes Please use Acetone to clean and dry the doctor blade, slurry feeder, and roller to avoid rusting Customers are welcome to visit our facility to receive technical training before shipping equipment (Please schedule an appointment with us in advance) On-site Training is available for customers within the US only (Expenses will be covered by the customers) Optional The atmosphere plasma cleaning add-on for the substrate is available upon request. Such a surface treatment will activate and increase the energy of the substrate surface and thus enable a better adhesion & bonding to the coating materials. Please click the pic. 1 below for more details. You may use the Precision Peristaltic Slurry Feeding Pump for continuous slurry delivery during the roll-to-roll coating process. ( Click Pic.2 & Pic. 3 in below to order ) You may order the Dual-Filtration System for NMP Vapor (Pic. 4) and connect it to the coating system to keep the environment healthy. You may order a Magnetic De-ironing Filtration system (Pic. 5) for optimizing the slurry condition Pic.1 Pic.2 Pic.3 Pic.4 Pic.5
