Method for making cold-set plug for ceramic honeycomb body

摘要

Various embodiments provide methods of making ceramic articles and cold-set plugs for ceramic honeycomb bodies. The methods of making ceramic articles include providing a ceramic honeycomb body and applying an aqueous composition to the ceramic honeycomb body to form a cold-set plug. The aqueous composition includes a refractory filler, an inorganic binder, and an organic binder. The refractory filler includes particles having a d50 ranging from about 10 μm to about 40 μm, a d10 greater than about 2 μm, and a d90 less than about 110 μm. Embodiments also provide methods of making the cold-set plug that include preparing the aqueous composition and forming the cold-set plug by applying the composition to the ceramic honeycomb body.

主权项

1. A method of making a cold-set plug for a ceramic honeycomb body, said method comprising:
preparing an aqueous composition comprising a refractory filler, an inorganic binder, and an organic binder; and forming a cold-set plug from the composition by applying the composition to the ceramic honeycomb body; wherein the composition is not fired before or after the cold-set plug is formed; wherein the refractory filler comprises particles; and wherein the particles of the refractory filler have a d50 ranging from about 10 μm to about 40 μm, a d10 greater than about 2 μm, and a d90 less than about 110 μm.
