Figure 1 From Modelling Of The Curtain Coating Process As A Basis For Such an operation only requires some sheets of the substrate to be coated on and a rather small amount of coating liquid in the order of 10 15kg per formulation. coating can be applied either in a single or in a multilayer mode. an example of such a sheet based coater is shown in the following picture. figure 5. Curtain coating a new coating process for speciality papers is emerging as a potential method for coating printing paper grades as well. in part 1, we discussed the operational principles of. The processing window for producing high quality coatings with this technique is bounded by two flow instabilities: the minimum flow rate to establish a stable curtain at the lower end, as illustrated in fig. 1 (b), and the maximum substrate speed that does not allow air bubbles to be entrained between liquid film and substrate at the higher end, as shown in fig. 1 (c). The operability limits of the process are set by different flow instabilities in the coating bead, such as air entrainment, low speed heels and curtain pulling in the impingement region, and by curtain breakup in the curtain flow region. edge guide are needed to maintain at specific width of the falling curtain.
