Embodiment 1

[0041] Preparation of Microcrystalline Bamboo Charcoal Ceramic Beads

[0042] Mix the raw materials evenly according to the ratio, add water in the granulator to granulate into spherical particles with different particle sizes.

[0043] 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 kaolin. The ingredients are mixed according to the ratio of 40% bamboo charcoal, 30% porous minerals, 25% clay and 5% binder. Add water and starch to the granulator to form spherical granules with a particle size of 0.5mm to 5mm, then air-dry the granules naturally for 24 hours, and then dry them in a drying oven at a temperature of 90°C for 4 hours before anaerobic sintering. Keep at 1250°C for 30 minutes, and cool naturally to obtain pottery pellet products. The performance indicators of the pottery pellets are shown in Table 1.

Abstract

A catalytic-materail-coated microcrystal bamboo-charcoal pottery bead is prepared by coating a microcrystal bamboo-charcoal pottery bead prepared from the following compositions in percent by weight with a catalytic material: 30-50% of bamboo charcoal powder, 30-40% of a porous nonmetal mineral powder, 20-30% of clay, and 2-5% of a binder. The preparation method of the catalytic-materail-coated microcrystal bamboo-charcoal pottery bead comprises: adding the catalytic material into a silica-gel water dispersion, stirring to form a suspension, then putting the microcrystal bamboo-charcoal pottery bead into the suspension, stirring, taking out the microcrystal bamboo-charcoal pottery bead and drying; or putting the microcrystal bamboo-charcoal pottery bead into the suspension for dipping, and taking out for drying. The photocatalysis function of the catalytic material and the extremely good adsorption of the microcrystal bamboo-charcoal pottery bead are integrated, the catalytic effect of the catalytic material is improved, and the preparation method is simple and application is convenient.

Description

technical field [0001] The invention relates to a novel pottery material, in particular to a novel ecological environment functional pottery material, more specifically to a microcrystalline bamboo charcoal pottery bead coated with a catalytic material 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 charcoal uses its...
