Embodiment 1

[0012] Add 1.5% industrial grade K to the main raw material for preparing honeycomb ceramics 2 CO 3 , after kneading, aging, extrusion molding, first dried at 100°C for 0.5h, then dried at 150°C for 1.5h, then fired in a kiln at a firing temperature of 1175°C. Just can obtain the glaze layer that covers evenly, and this glaze layer is not softened at 900 ℃ through anti-softening test.

Embodiment 2

[0014] Add 2% industrial grade Na to the main raw material for preparing honeycomb ceramics 2 CO 3 , after kneading, aging, extrusion molding, firstly dried at 100°C for 1.5h, then dried at 150°C for 1h, and fired in a kiln at a firing temperature of 1155°C. Just can obtain the glaze layer that covers evenly, and this glaze layer is not softened at 800 ℃ through anti-softening test.

Embodiment 3

[0016] Add 2% Na to the main raw material for preparing honeycomb ceramics 2 CO 3 and 1% K 2 CO 3 , after kneading, aging, extrusion molding, firstly dried at 100°C for 1 hour, then dried at 150°C for 1 hour, and fired in a kiln at a firing temperature of 1160°C. Just can obtain the glaze layer that covers evenly, and this glaze layer is not softened at 850 ℃ through anti-softening test.

Abstract

The invention discloses honeycomb ceramic. The honeycomb ceramic is prepared by the following steps of: adding 1 to 8 weight percent (dry-weight based weight ratio) of soluble inorganic salt into a raw material; performing full vacuum refining and molding; drying at the temperature of 100 DEG C for 0.5 to 2 hours; drying at the temperature of 150 DEG C for 0.5 to 2 hours; and sintering at the temperature of between 1,100 DEG C and 1,180 DEG C.

Description

technical field [0001] The invention belongs to the technical field of inorganic non-metallic materials, and in particular relates to a honeycomb ceramic and a production method of the honeycomb ceramic. Background technique [0002] As a functional porous material, honeycomb ceramics are widely used in industrial flue gas treatment, filter materials, catalyst carriers, heat storage bodies and other fields due to their high specific surface area and good physical and chemical stability. With the development of technology, its scope of application is also expanding. Its production method is generally to use raw materials such as kaolin, talc, clay, etc., after the clay is molded, it is sintered at high temperature. [0003] Because honeycomb ceramics have a porous structure, the water absorption rate is relatively large, and it is generally easy to absorb dust in the waste gas in industrial flue gas treatment, resulting in blockage of the pores, and it is not easy to clean, ...
