EQ-HDS-100 is a hybrid film applicator that can do tape coating for thicker film and slot die coating for thin film. It is an excellent tool to make lab scaled film coator via slurry for battery electrodes, perovskite solar film, and fuel cell membranes. This applicator can be used for all brand film coaters. Structure The hybrid film applicator includes two parts, which are made of stainless steel. 100 mm width doctor blade with dual micrometers to adjust film thickness at the range at 0.01 mm - 5 mm (click Picture 1 to see details) 50 mm width slot head, which can be fixed on the doctor blade to coat film thickness from 0.005mm - 0.02 mm (click Picture 1 to see details) which includes ( see picture left column) 2 pcs of 0.2 mm thickness Shim 2 pcs of 0.3 mm thickness shim 2 pcs of 0.4 mm thickness shim 1 pcs PTFE tube ( 1/8"OD x 2.175 mm ID) Join connectors to pump and slot die Other widths slots die heads (10 or 30 mm) may be installed on the doctor blade upon request (Pic.2) The PTFE buffering pad installed on the bottom of the doctor blade to reduce friction (Pic. 3) Pic.1 Pic.2 Pic.3 Micrometer Head Digital micrometer head accuracy: +/- 0,001 mm The micrometer heads are built-in doctor blade frame to adjust the gap between the slot die and the substrate Optional Coater The most suitable for the hybrid film applicator is MSK-AFA-HC100 coater. because it has a lapped glass surface and < flatness of +/- 2 microns. Please click the Pic. 1 below right to order separately Slot die is removable if using the doctor blade head for tape coating For slot die coating, you may order a Syringe Pump as Pic. 2 below: Pic. 1 Pic. 2 Application Note Coating thickness is not dependent on or equal to the gap between the slot die head and substrate. Usually, the gap shall be larger than the coating thickness. Coated thickness is strongly dependent on slurry viscosity, coating speed, and flow speed. ( Lower viscosity, low flow rate, and low speed will result in the thinner film. Please practice finding the best parameters which suitable for you Example 5% carbon+ polymer, viscosity: 500mPa·s, substrate: Al foil of 16 um, Gap: 200 um, Slurry feeding rate:: 0.1 ml/minute , Coating speed: 12mm/s Dry coated film thickness: 5 um +/- 1 um
