Embodiment 1

[0043] Preparation of Microcrystalline Bamboo Charcoal Honeycomb Ceramic Air Filter Panel

[0044] The average particle size of the used bamboo charcoal powder, porous non-metallic mineral powder and clay is 1-10 μm. The porous non-metallic mineral adopts zeolite, and the clay adopts attapulgite. Mix ingredients according to the ratio of 35% bamboo charcoal, 45% porous minerals, 18% clay and 2% binder. The process of preparing the microcrystalline bamboo charcoal honeycomb ceramic air filter plate is as follows: add water, dextrose, refine the mud, and stale, then add the mud to a special honeycomb ceramic carrier extrusion mold for extrusion molding, let it dry naturally for 24 hours, and then put Put it into a constant temperature drying oven, adjust the temperature to 90°C and dry for more than 4 hours; then put it into a sintering furnace for anaerobic sintering at a sintering temperature of 1250°C, keep it for 30 minutes, and naturally cool to obtain a microcrystalline b...

Abstract

A microcrystalline bamboo-charcoal cellular pottery-texture air filter panel with catalytic function is prepared by using a catalytic material to coat a microcrystalline bamboo-charcoal cellular pottery-texture air filter panel prepared from the following compositions in percent by weight: 20-40% of bamboo charcoal powder, 40-60% of porous nonmetal mineral powder, 10-30% of clay and 2-5% of a binder. The preparation method of the air filter panel comprises: adding the catalytic material into a silica gel water dispersion, stirring to form a suspension, and then putting the microcrystalline bamboo-charcoal cellular pottery-texture air filter panel into the suspension for dipping, taking out and drying. The photocatalytic function of the catalytic material and the adsorption function of the microcrystalline bamboo-charcoal cellular pottery-texture air filter panel are integrated, so that the photocatalytic effect of the catalytic material is improved, and the preparation method is simple and convenient to apply.

Description

technical field [0001] The invention relates to a novel pottery material, in particular to a novel ecological environment function pottery material, more specifically to a microcrystalline bamboo charcoal honeycomb ceramic air filter plate with a catalytic function and a preparation method thereof. Background technique [0002] Bamboo charcoal has a rich honeycomb microporous structure. This microporous structure makes bamboo charcoal have a large specific surface area and excellent adsorption function. It also has special effects such as electromagnetic shielding, radiating far-infrared rays, generating negative ions, and increasing water alkalinity. It is used for moisture absorption, deodorization, disinfection, sterilization, heat storage, humidity control, and improving the living environment. When the ambient humidity is high, bamboo charcoal uses its hygroscopic effect to absorb moisture in the indoor air; on the contrary, when the ambient humidity is low, bamboo char...
