Estimating the term…
A leaf coater, in which a constant quantity of a coating solution is supplied intermittently from a coating solution supply source through a predetermined coating solution quantity intermittent supply and a coating solution applier to a blank substrate, for coating blank substrates one by one with the coating solution, characterized in that a coating solution filtration is provided in the coating solution flow pipeline from the coating solution supply source to the coating solution applier, and the Young's modulus of the filter medium in the coating solution filtration is not less than 200 MPa, while the pore size of the filter medium is in the range of 0.05 μm to 100 μm; and a method for producing coated substrates using the leaf coater.
A leaf coater comprising the combination of a coating solution supply source, a coating solution quantity intermittent supply means, a coating solution applying means for applying coating solution to each blank substrate, a first coating solution flow pipeline connecting the coating solution supply source with the intermittent supply means, a second coating solution flow pipeline connecting the intermittent supply means with the applying means, and a coating solution filtration means provided in either the first or second coating solution flow pipeline, which comprises a housing having an inlet and an outlet of the coating solution and a coating solution filtration means composed of a filter medium provided in the passage of the coating solution in the housing, wherein the Young's modulus of the filter medium in the filtration means is not less than 200 MPa and the pore size of the filter medium is in the range of 0.05 to 100 μm.
