Embodiment 1

[0029] A preparation process of pure natural nanoscale superfine calcium powder, comprising the following steps:

[0030] 1) Material selection: take an appropriate amount of ore;

[0031] 2) Pretreatment: remove impurities on the ore surface;

[0032] 3) Cleaning: Preliminary cleaning, secondary cleaning, and deep cleaning are carried out on the pretreated ore. The primary cleaning is to use water washing and grinding to remove the surface stains and skin of the raw materials; 1.5-2.5 GPM nozzle sprays the raw material for 15-20 minutes to remove heavy metals and stubborn sludge on the surface of the raw material;

[0033] 4) Pulverization: pulverize the cleaned raw materials to pass 100 meshes to make the raw materials into small particles, and the particle size of the small particles is 5-10 mm;

[0034] 5) Calcination: Put the pulverized small particles in a high-temperature calciner, first heat up to 350-400°C for 2-2.5 hours, and then heat up to 1000-1200°C for 1-2 hou...

Embodiment 2

[0040] A preparation process of pure natural nanoscale superfine calcium powder, comprising the following steps:

[0041] 1) Material selection: take an appropriate amount of oyster shells;

[0042] 2) Pretreatment: remove impurities on the surface of oyster shells and internal carrion;

[0043] 3) Cleaning: Preliminary cleaning, secondary cleaning, and deep cleaning are carried out on the pretreated oyster shells. The primary cleaning is to use water washing and polishing to remove the surface stains and skin of the raw materials; the second cleaning puts the raw materials in alkaline protease In the aqueous solution, the pH of the solution is 11, the temperature of the aqueous solution is 50°C, soak for 4 hours, stir the raw materials every half an hour while soaking, use alkaline protease to effectively remove the residual carrion inside, and finally wash the surface of the raw materials with clean water ; Deep cleaning is carried out by soaking in acid water for 3 hours, ...

Embodiment 3

[0051] A preparation process of pure natural nanoscale superfine calcium powder, comprising the following steps:

[0052] 1) Material selection: take appropriate amount of clams;

[0053] 2) Pretreatment: remove surface impurities and internal carrion of giant clam shells;

[0054] 3) Cleaning: Preliminary cleaning, secondary cleaning, and deep cleaning are carried out on the pretreated giant clam shells. The primary cleaning is to use water washing and polishing to remove surface stains and epidermis of the raw materials; the secondary cleaning puts the raw materials in alkaline In the aqueous solution of protease, the pH of the solution is 11, the temperature of the aqueous solution is 50°C, soak for 4 hours, and stir the raw materials every half an hour while soaking, using alkaline protease can effectively remove the residual carrion inside, and then wash the raw materials with clean water Surface: Soak in acid water for 3 hours for deep cleaning, and then clean with clea...

Description

technical field [0001] The invention relates to the technical field of acid neutralizers, in particular to a preparation process of pure natural nanoscale superfine calcium powder. Background technique [0002] Calcium is the mineral with the most content in the human body. 99% of calcium exists in bones and teeth, and 1% exists in our blood, which is called blood calcium. The lack of calcium in the human body will cause stubborn porosis. According to the survey of the Chinese Medical Association, the average daily intake of calcium in China is only about 400 mg, while the daily calcium supplement recommended by the Chinese Medical Association is 800-1000 mg. In order to maintain the concentration of calcium in the blood, the body will draw out the calcium in the bones to replenish it in the blood, resulting in the loss of calcium in the bones. This situation is called calcium deficiency in the body. Calcium supplementation can be achieved by eating calcium-containing foods...
