Abstract
A method of plugging a honeycomb body is disclosed herein, the method comprising: contacting a first end of the honeycomb body comprising a plurality of channels with a light curable sealing mixture such that an infiltrate of the light curable sealing mixture flows into the plurality of channels proximate the first end; emitting a light toward a first portion of the infiltrate within the plurality channels of the filter; and curing the first portion of the infiltrate within the channels with the light to form a plurality of seals.
Claims19
A method of plugging a honeycomb body, the method comprising the steps:
- contacting a first end of the honeycomb body comprising a plurality of channels with a light curable sealing mixture disposed in a light transparent container such that an infiltrate of the light curable sealing mixture flows into the plurality of channels proximate the first end;
- emitting a light directed at the first end of the honeycomb body to expose a first portion of the infiltrate within the plurality channels to the light, wherein the light is emitted from a light source which is positioned such that the light passes through the container prior to reaching the honeycomb body;
- and
- curing the first portion of the infiltrate within the channels with the light to form a plurality of seals.
A method of plugging a honeycomb body, comprising the steps:
- contacting a first end of the honeycomb body comprising a plurality of channels with an ultraviolet curable sealing mixture disposed in a container such that an infiltrate of the ultraviolet curable sealing mixture flows into the plurality of channels proximate the first end;
- emitting a light comprising ultraviolet light toward a first portion of the infiltrate within the plurality channels of the honeycomb body;
- curing the first portion of the infiltrate positioned within the channels with the light to form a plurality of seals in the plurality of channels, wherein the light is emitted from a light source which is positioned such that the light passes through the container prior to reaching the honeycomb body;
- and
- removing the honeycomb body from the ultraviolet curable sealing mixture such that a second portion of the infiltrate drains from the channels.
A method of plugging a honeycomb body, comprising the steps:
- contacting a first end of the honeycomb body comprising a plurality of channels with a ultraviolet curable sealing mixture such that an infiltrate of the ultraviolet curable sealing mixture flows into the plurality of channels proximate the first end;
- imaging the first end of the honeycomb body through the ultraviolet curable sealing mixture;
- emitting a light comprising ultraviolet light toward a first portion of the infiltrate within a first portion of the plurality channels of the honeycomb body;
- curing the first portion of the infiltrate positioned within the first portion of the plurality of channels with the light to form a plurality of seals;
- removing the honeycomb body from the ultraviolet curable sealing mixture such that a second portion of the infiltrate drains from the channels;
- and
- removing the plurality of seals from the honeycomb body.
