Embodiment 1

[0065] Invisible chlorine dioxide oyster shell calcium supplement deodorization antibacterial material is prepared as follows:

[0066] In the first step, the oyster shells that have been piled up for natural fermentation and purification are firstly cleaned with clean water, then dried in the sun or in the shade under natural ventilation conditions, and finally crushed to particles with a particle size of 0.4-0.5mm to make raw meal;

[0067] In the second step, the above-mentioned raw material is put into a high-temperature furnace, and the clinker is obtained by a three-stage stepped heating calcination method; the specific calcination steps are as follows:

[0068] First, heat up to 300°C at a heating rate of 2°C / min, and then keep it warm for 10 minutes;

[0069] Then, continue to heat up to 650°C at a heating rate of 5°C / min, and keep it warm for 15 minutes; then, ventilate and cool down to 600°C;

[0070] Then raise the temperature to 810°C at a heating rate of 10°C / min...

Embodiment 2

[0074] Invisible chlorine dioxide oyster shell calcium supplement deodorization antibacterial material is prepared as follows:

[0075] In the first step, the oyster shells that have been naturally fermented and purified are first cleaned with clean water, then dried in the sun or in the shade under natural ventilation, and then crushed to particles with a particle size of 2.5-3.5mm to make raw meal;

[0076] In the second step, the above-mentioned raw material is put into a high-temperature furnace, and the clinker is obtained by a three-stage stepped heating calcination method; the specific calcination steps are as follows:

[0077] First raise the temperature to 350°C at a heating rate of 2°C / min, and then keep it warm for 10 minutes;

[0078] Then, continue to heat up to 650°C at a heating rate of 5°C / min, then keep it warm for 20 minutes; then, ventilate and cool down to 600°C;

[0079] Then raise the temperature to 830°C at a heating rate of 10°C / min, and keep it warm f...

Abstract

The invention discloses an oyster shell-invisible chlorine dioxide antibacterial material and a preparation method thereof. The oyster shell-invisible chlorine dioxide antibacterial material is a mixture of oyster shell powder, sodium chlorite powder and sodium hydrogen sulfate powder of which the particle size is not greater than 50 microns, and the weight ratio of the three types of powder is 1:(0.05-0.1):(0.1-0.2), wherein the oyster shell powder adopts a loose multihole structure, and is high-activity powder prepared by calcining and grinding the oyster shell serving as a raw material.Clinker is prepared by a three-stage stepped heating calcining method, so that the antibacterial material with the loose multihole structure and high chemical activity can be obtained; when used as a poultry feed additive, the antibacterial material can effectively supplement calcium of poultries and eliminate odor of excrements of the poultries, thus fulfilling multiple aims of improving the environment in a poultry housing, enhancing the physique of the poultries and benefiting the health of keepers. Compared with the prior art, the oyster shell-invisible chlorine dioxide antibacterial material disclosed by the invention has the characteristics of low cost, energy conservation, environment protection, use safety, efficiency, environmental friendliness and the like.

Description

technical field [0001] The invention relates to an antibacterial material, a preparation method and a use method thereof, in particular to an invisible chlorine dioxide oyster shell calcium-supplementing and deodorizing antibacterial material and a preparation method thereof, belonging to the technical field of oyster shell modification. Background technique [0002] According to statistics from the Food and Agriculture Organization of the United Nations (FAO), in 1985 my country's egg production reached 4.278 million tons, surpassing the United States to become the world's number one, and continued to grow rapidly in the following 10 years. In 1996, my country's egg production exceeded 15 million tons, accounting for the world's total egg production. The proportion is 35%. In 2014, the number of laying hens in my country exceeded 1.1 billion, the egg output reached about 24.5 million tons, and the output value exceeded 1.2 billion yuan, which was about 7 times that of India ...
