Problems solved by technology

However, since most microorganisms cannot survive at high temperatures, and have little effect on inorganic materials at room temperature, in the prior art, except for using Thiobacillus ferrooxidans (T.f. bacteria) to whiten pyrite-containing kaolin There is no record of microbial treatment of inorganic materials such as ceramic raw materials, except for research records.

Embodiment 1

[0022] Embodiment 1 First prepare the microbial fermentation medium. Dilute 300 grams of brown sugar with 25% water, 400 grams of honey, 1000 grams of sterile fruit juice, and 10 kilograms of common enzymes to make a microbial fermentation culture solution.

[0023] Put lactic acid bacteria with a total colony of about 70 billion, yeast flora with a total of about 60 billion, and blueberry flora with a total of about 10 million colonies into the microbial nutrient solution prepared above, and control the temperature at 5-28°C Cultivate under certain conditions for 24-72 hours. If the temperature is too low, it can be extended to 100 hours to obtain the cultured microbial group.

[0024] Mix the cultivated microbial group and the microbial culture solution evenly into 70 kg of kaolin, put it into decay at room temperature for 150 hours, then dry the kaolin, put it into a furnace for calcination at 300-800°C, and obtain the calcined improved The modified clay is molded into a c...

Embodiment 2

[0025] Example 2 The sugar-based microbial fermentation culture solution was used to cultivate lactic acid bacteria, and the microbial culture solution was mixed with the clay according to the weight ratio of 200 billion: 15 kg of total bacterial colonies and clay for stale treatment. The treatment temperature was normal temperature and the treatment time was 200 hours. After the clay was modified by lactic acid bacteria, its particle shape and molecular structure changed slightly. Then the clay is dried and put into a furnace for calcination at 500-800° C. to remove organic impurities and fix the properties of the modified clay. The modified clay is ground, added with other ceramic raw materials and auxiliary materials, made into a billet, and then fired to obtain the bioceramics of the present invention.

[0026] Then kaolin is dried, put into a furnace and calcined at 300-800°C to obtain the calcined modified clay, and the modified clay is molded into a ceramic body, glazed...

Embodiment 3

[0027] Example 3 Use microbial fermentation culture liquid to cultivate yeast and penicillin bacteria, mix microbial culture medium and kaolin according to the ratio of 500 billion to 10 kg by weight of the total amount of colonies and kaolin for stale treatment, and stale at room temperature for 100 hours. Then the treated kaolin is dried and calcined at 600° C. to obtain the calcined modified clay. The modified clay is molded into a ceramic body and fired according to the conventional pottery-making process to obtain the biofunctional ceramics.

[0028] After testing and experiments, the biofunctional ceramics can reduce water molecular clusters, and have anti-oxidation effects, and can remove harmful substances such as pesticide residues, clenbuterol, hormones, antibiotics, fluorine, chlorine, nitrite, etc.; nicotine content. And has the antibacterial effect of good medicine.

Abstract

The invention discloses bio-functional ceramic and a preparation method thereof. The bio-functional ceramic takes clay as a main raw material, and is characterized in that the raw material clay is modified clay obtained after banalizing and decomposing are conducted through microorganisms, the modified clay is calcined and then crushed to prepare a ceramic blank, the ceramic blank is fired, and thus the bio-functional ceramic is prepared. The microorganisms such as bacteria and fungi are adopted for the first time to conduct banalizing and modifying treatment on the main raw material, namely the clay, of the ceramic, thus the microstructure of the clay is changed, accordingly the bio-functional ceramic with various functions and various active functions is obtained, and the use and beneficial functions of the ceramic are expanded.

Description

technical field [0001] The invention belongs to the application technology of microbial technology in a new field, and in particular relates to a biofunctional ceramic obtained by using microorganisms to modify ceramic raw materials and a preparation method thereof. Background technique [0002] Functional ceramics refer to ceramic materials whose non-mechanical properties are mainly used in applications. Such ceramic materials usually have one or more functions, such as electric, magnetic, optical, thermal, chemical, biological functions, etc.; some also have coupling functions such as piezoelectric, piezoelectric, pyroelectric, electro-optic, acousto-optic, magneto-optic ,. With the rapid development of material science, various new properties and new applications of functional ceramic materials are constantly being recognized and actively developed. Functional ceramics in the prior art are mainly obtained by adding various new materials such as hydroxyapatite, calcium c...
