Process and apparatus for coating a substrate

摘要

The invention relates to the process and apparatus coating of a substrate, particularly a glass ribbon, with a pulverulent product. The invention proposes the implementation of a distribution nozzle (10, 24) that sprays the pulverulent product in suspension in a gas, and a suction device (14) for evacuating the resultant waste of the decomposition of the pulverulent product from a coating zone (Z). The invention concerns the formation of at least one to extend the residence time of the pulverulent product in the coating zone to facilitate its deposit on the substrate. The invention also concerns the production of substrates, particularly glazings, coated with metal oxides.
