| Description |
We have an urgent requirement for a ceramic slurry coating / impregnation technology, used to produce ceramic filtration media from a reticulated polymer foam substrate.
Currently reticulated polymer foam filters, with ppi (pores per linear inch) ranging from 20 - 6 ppi, are coated with a ceramic slurry by first impregnating via submerged rollers, then spraying a more diluted version of the same slurry composition. When considering a coarse foam a strand thickness of 1-3mm is deposited during the impregnation process, and less than 1mm is added during the spray process. The spray process is a continuous one and the drying is done in batches. The process of spray, air knife and dry, is performed twice on each side of the filter (4-spray process). 30-50% of the total filter weight is added by spraying. The spray slurry viscosity is around 2.7 – 3.1 PaS and the solids content is approx. 60-70% (depending on the end product) The filters are then dried and fired prior to use. The... more |
