Problems solved by technology

The problems of these biological carriers are: (1) Activated carbon: Although it has a huge specific surface area and strong adsorption capacity, the physical strength of activated carbon is low, the life is short, it is not easy to clean, and the treatment cost is high.
(3) Other bio-ceramic materials commonly used at present also have many defects: low porosity, especially low micropore content and insufficient surface roughness

Embodiment 1

[0046] Embodiment 1: Preparation of microcrystalline bamboo charcoal purple sand composite ceramsite filter material

[0047] The percentage by weight of raw materials is: 20-30% of microcrystalline bamboo charcoal, 40-55% of purple sand raw material, 10-30% of attapulgite, 5-30% of diatomite and 1-5% of binder.

[0048] Mix the proportions according to the proportion, after mixing by the mixer, add water to granulate in the granulator to form spherical particles with a particle size of 1-10mm, then dry the granules, and then put them into the sintering furnace for anaerobic sintering, and finally sintering The temperature is 800-1150°C, and the product can be obtained after cooling. For the preparation method, see figure 1 , the main properties are shown in Table 5.

Embodiment 2

[0052] Embodiment 2: Preparation of microcrystalline bamboo charcoal purple sand composite pottery tea set and rice cooker

[0053] The weight percentages of the raw materials are: 10-20% microcrystalline bamboo charcoal, 40-60% purple sand, 5-10% attapulgite, 2-5% diatomite, and 5% binder.

[0054] Grind microcrystalline bamboo charcoal, purple sand raw materials, attapulgite, and diatomaceous earth to a size below 200 meshes, mix them in proportion, add water to make the mud, and age it for several days (the degree of mud refining and the aging time depend on meeting the molding conditions), so that The water content of the mud mud is uniformly associated, and the mud material is added to the spinning machine for spinning and forming; after forming, it is air-dried first, and then put into a sintering furnace for anaerobic sintering. The final sintering temperature is 800-1150°C, and finally cooled to obtain the product. For the preparation method, see figure 2 , the main ...

Embodiment 3

[0058] Embodiment 3: the preparation of microcrystalline bamboo charcoal purple sand composite honeycomb or porous pottery

[0059] The weight percentages of the raw materials are: 20-30% microcrystalline bamboo charcoal, 30-45% purple sand, 5-15% attapulgite, about 5% diatomite, and about 5% binder.

[0060] Grind microcrystalline bamboo charcoal, purple sand raw materials, attapulgite, and diatomaceous earth, and mix them according to the proportion below 200 meshes. Put it into a forming abrasive tool and extrude it; after forming, let it dry naturally; then put it into a sintering furnace for anaerobic sintering, the final sintering temperature is 800-1150°C, and finally cool down to get the product. For the preparation method, see image 3 , the main performance indicators are shown in Table 7.

Abstract

The invention relates to a microcrystal bamboo charcoal purple sand composite pottery material and application of the microcrystal bamboo charcoal purple sand composite pottery material. The microcrystal bamboo charcoal purple sand composite pottery material is composed of, by weight, 5-40% of microcrystal bamboo charcoal powder, 40-60% of purple sand powder, 10-30% of attapulgite, 5-30% of kieselguhr and 1-5% of binder in a mixing mode. The microcrystal bamboo charcoal purple sand composite pottery material can be used for manufacturing a microcrystal bamboo charcoal purple sand composite pottery, the steps for manufacturing the microcrystal bamboo charcoal purple sand composite pottery are specifically forming, air drying, drying, calcination and cooling, and therefore the microcrystal bamboo charcoal purple sand composite pottery can be obtained. According to the microcrystal bamboo charcoal purple sand composite pottery material and the application of the microcrystal bamboo charcoal purple sand composite pottery material, through different raw material ratios and calcination crafts, the manufactured microcrystal bamboo charcoal pottery after processing is low in firing shrinkage coefficient, high in bending strength and strong in adsorption of formaldehyde, phenol, sulfur dioxide, TVOC and other hazardous substances and can be manufactured into pottery materials of different water adsorption rates as required.

Description

technical field [0001] The invention relates to a microcrystalline bamboo charcoal and purple sand composite pottery material with high adsorption performance and an application thereof, belonging to the field of composite pottery materials. Background technique [0002] Bamboo plants grow fast, have strong reproductive ability, and are easy to regenerate. Bamboo has many excellent properties such as high strength and good toughness. The high-temperature microcrystalline bamboo charcoal produced from it is hard, fine and porous, has a large specific surface area and strong adsorption force. It can not only be used in fuel energy, environmental purification, moisture absorption and deodorization of living rooms, soil improvement, fruit and vegetable preservation, daily health care, etc. , It can also be used in high-tech fields such as radiation protection, electromagnetic shielding, flame-retardant composite materials, and semiconductor materials. [0003] Due to a series o...
