Abstract
A method of applying a circumferential coating material on a circumferential surface of a ceramic honeycomb structure to form a circumferential coat layer. The method includes vertically aligning the longitudinal axis of the ceramic honeycomb structure, rotating the ceramic honeycomb structure around the vertically-aligned longitudinal axis, and applying the circumferential coating material on the circumferential surface of the rotating honeycomb structure at a discharge speed of 50 to 120 mm/s, calculated by Discharge speed V [mm/s]=Supplied amount q [g/s] of circumferential coating material÷(Density ρ [g/mm3] of circumferential coating material×Area S [mm2] of discharge opening).
Claims5
A method of
- applying a circumferential coating material on a circumferential surface of a ceramic honeycomb structure to form a circumferential coat layer, comprising:
- (a) vertically aligning the longitudinal axis of the honeycomb structure and rotating the honeycomb structure around the center of the vertically-aligned longitudinal axis;
- and
- (b) discharging the circumferential coating material from a discharge nozzle disposed at a position opposite to the circumferential surface of the honeycomb structure to apply the circumferential coating material on the circumferential surface of the rotating honeycomb structure,
- wherein a discharge speed V of the circumferential coating material is 50 to 120 mm/s
- as calculated by:
- V
- =
- q
- ρ
- ·
- S
- where q is the supplied amount of the circumferential coating material in grams/second, p is the density of the circumferential coating material in grams/mm3, and S in the area of the discharge opening of the discharge nozzle in mm2.
