APPARATUS AND METHOD FOR COATING SUBSTRATES WITH WASHCOATS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240024898 titled 'APPARATUS AND METHOD FOR COATING SUBSTRATES WITH WASHCOATS

Simplified Explanation

The abstract describes a washcoat showerhead for depositing a washcoat onto a substrate. The showerhead includes a housing with an inlet for receiving the washcoat, a showerhead plate, and a baffle. The housing and showerhead plate create a showerhead cavity, with the baffle located inside. The showerhead plate has multiple nozzle apertures for discharging the washcoat onto the substrate. The baffle consists of an impermeable central body and several arms extending from it, which define flow apertures arranged around the central body.

  • The washcoat showerhead is designed to deposit a washcoat onto a substrate.
  • The housing receives the washcoat, which is then discharged through the nozzle apertures of the showerhead plate.
  • The baffle, located within the showerhead cavity, helps control the flow of the washcoat.
  • The baffle's impermeable central body and arms with flow apertures ensure proper distribution of the washcoat onto the substrate.

Potential applications of this technology:

  • Coating substrates with a washcoat in various industries such as automotive, electronics, and energy.
  • Deposition of catalysts or protective coatings onto surfaces.
  • Applying thin films or layers onto substrates for functional purposes.

Problems solved by this technology:

  • Ensures uniform and controlled deposition of the washcoat onto the substrate.
  • Prevents clogging or uneven distribution of the washcoat during the deposition process.
  • Provides a reliable and efficient method for applying coatings or films onto substrates.

Benefits of this technology:

  • Improved coating quality and consistency.
  • Enhanced efficiency and productivity in the deposition process.
  • Reduced material waste and cost.
  • Enables precise control over the thickness and distribution of the washcoat.
  • Versatile and adaptable for various substrate types and sizes.


Original Abstract Submitted

a washcoat showerhead for depositing a washcoat onto a face of a substrate comprises a housing having an inlet for receiving the washcoat, a showerhead plate and a baffle. the housing and showerhead plate define a showerhead cavity with the baffle located within the showerhead cavity. the showerhead plate has a plurality of nozzle apertures for discharging the washcoat towards the face of the substrate. the baffle comprises an impermeable central body and a plurality of arms extending from the impermeable central body, the plurality of arms defining a plurality of flow apertures circumferentially arranged around the impermeable central body.
