Embodiment 1

[0014] The preparation process of charcoal pottery for air purification includes the following steps in turn: (1) green body molding, mixing bamboo charcoal powder, clay, glycerin, silver nitrate, vegetable oil and water, adding each raw material to a mixer, stirring and kneading After the mud is vacuum smelted in the mud machine, it is extruded through the extruder, and the green body is honeycomb-shaped; (2) firing, cleaning the surface before drying, and then drying the green body into the kiln for high-temperature firing. Between 750-1100°C, the oxygen barrier burial method is used for firing, and the green body is placed in a fully airtight container with good thermal conductivity, and the green body is treated with bamboo charcoal powder around the green body in the container. Sealed, the container is one of high temperature resistant metal box, silicon carbide, mullite or cordierite saggar, to prevent the oxidation of bamboo charcoal during firing; the carbon content of ...

Embodiment 2

[0019] The preparation process of carbon pottery for air purification, the green body is prepared from the following raw materials according to the mass percentage: 70% bamboo charcoal powder, 15% clay, 5% glycerin, 3% vegetable oil, 0.5‰ silver nitrate, and the balance is water. The carbon content in the fired carbon pottery accounts for 66% of its overall mass. After the firing is completed, the nano-titanium dioxide aqueous solution is sprayed on the surface of the carbon pottery. The quality of the sprayed nano-titanium dioxide aqueous solution is 40% of the mass of the carbon pottery. The surface area is 250 square meters per gram, the concentration of the nano-titanium dioxide solution is 1%, the nano-titanium dioxide is 4% of the mass of the fired carbon pottery, and the dispersant is one of ethylene glycol or isopropanol. Others are the same as in Example 1.

Embodiment 3

[0021] The preparation process of carbon pottery for air purification, the green body is prepared from the following raw materials according to the mass percentage: bamboo charcoal powder 50%, clay 35%, glycerin 2%, vegetable oil 7%, silver nitrate 0.5‰, and the balance is water. The carbon content in the fired carbon pottery accounts for 45% of its overall mass, and the impregnated quality of the nano-titanium dioxide aqueous solution in the carbon pottery after soaking is 30% of the mass of the carbon pottery, and the specific surface area of ​​the obtained carbon pottery is 200 square meters per gram. Others are the same as in Example 1.

Abstract

The invention relates to a preparation process for carbon pottery. The preparation process for the carbon pottery for purifying air comprises the following steps in sequence: 1-, molding a body; 2-, firing; and 3-, soaking the molded body in a nano-titanium dioxide aqueous solution or spraying the nano-titanium dioxide aqueous solution onto the molded body. The preparation process for the carbon pottery for purifying air has the advantages that silver ions and nano-titanium dioxide are loaded on the prepared carbon pottery, and an adsorption function, a decomposition function and an antibacterial function are integrated.

Description

technical field [0001] The invention relates to a preparation process of carbon pottery, in particular to a preparation process of carbon pottery for purifying air. Background technique [0002] Bamboo charcoal products loaded with silver ions and nano-titanium dioxide are widely used for air purification. The bamboo charcoal product that is used for air purification in the prior art is as " 101041134 " in Chinese Patent Publication No., and the name is called " surface rich AG porous TIO Modified bamboo charcoal and preparation method thereof " described in the patent, " nano-modified bamboo charcoal, the surface AG-rich porous TIO2 modified bamboo charcoal, including pretreated bamboo charcoal raw materials and TIO2 nano-sol filled with pore-forming agent AG / N co-doped in bamboo charcoal ducts or vascular bundles, wherein, containing pore-forming agent AG / N co-doped Miscellaneous TIO2 nano sols include the following components: TIO2 sol particles, pore-forming agents, nit...
