Compact Roll to Roll Slot die Coater w/ 300mm Max. effective coating width
I. Equipment parameters
Basic material thickness: Aluminum foil: 0.010-0.030mm,
Copper foil:0.006~0.030mm
2. Basic material width: Aluminum foil:100-320mm, copper foil: 100-320mm
3.The max. thickness of wet coating:8-400um(Viscosity of the slurry be allowed)
4.The Max. coating width:300mm, the max. coating roll width:360mm
5.The mechanical tape speed:0.5-7m/min
6.The coating speed:0.1-1.0m/min (different from the slurry material thickness, viscosity(The speed is different according to the slurry. This parameter is only based on the 6m oven length and the coating requirements of the lithium battery, and a range is for reference.The coating of ultracapacitors is faster, and usually can be set to about 2M/min) .
7.Drying oven length: 1 part dry oven * 1.0m/part=1.0m
II. Equipment specification
Coating method: Slot die coating
Intermittent coating distance: 5-8000 mm±1 mm (adjustable according to battery specifications)
Coating precision:
2.1 dry thickness of the accuracy tolerance::single-side cathode:±2.5um, anode:±2.5um (cross-section measurement 4-5 points, vertical section measurement spacing is 100mm)
2.2 Coating the positive and negative alignment tolerance : <± 1.0mm
2.3 The average length tolerance:≤±1.0mm
2.4 The average width tolerance:≤±1.0mm
Remarked: The first and second indicators above should have the best effect when the slurry conditions (viscosity, particle size, uniformity, etc.) match the settings of the equipment parameters
Battery inner diameter:3 inch, Adopt the air expansion roller
Tension control: Coated floating roller tension PID control
Deviation correction control accuracy: ±0.01mm, deviation accuracy:±1mm
The operator operates the coating mechanism from the front
Dry Type:
A.Hot air drying, hot air circulation(upper supply air); or upper and lower supply air
B.Heating: electric heating 5.0 KW*1 part=5.0 KW
C.Heater
8. Oven length:1part*1.2m/part=1.2m
9. Oven material: Stainless steel
10. Oven temperature:Room temperature ~150ºC,adjustable, temperature control accuracy <±5ºC
