Problems solved by technology

However, as the particle size of metal copper powder and metal iron powder decreases, their oxidation resistance also decreases. Therefore, how to solve the contradiction between particle size and stability is a major problem in the practical application of ultrafine powder.

Embodiment 1

[0030] 1) Grinding the montmorillonite produced in Inner Mongolia to 300 mesh, adding water and stirring evenly to make a suspension slurry with a concentration of 10%;

[0031] 2) the zinc content is the zinc sulfate of 1.5% of montmorillonite weight, and the molar ratio is the sodium sulfite of 5 times of zinc sulfate, slowly add in the suspension slurry of step 1) under stirring, pass N 2 Reaction at 50°C for 2 hours;

[0032] 3) centrifugal dehydration of the suspension slurry in step 2);

[0033] 4) Drying and crushing the filter cake obtained in step 3) to 300 meshes to obtain a zinc supplement of loaded ultrafine zinc powder.

[0034] The transmission electron microscope observation shows that the average particle size of the ultrafine zinc powder supported by montmorillonite is 8nm, and the particle size distribution is between 3nm and 12nm. The content of zinc in montmorillonite is 1.5% by weight.

Embodiment 2

[0036] 1) Grinding the clinoptilolite produced in Jinyun, Zhejiang to 400 mesh, adding water and stirring evenly to make a suspension slurry with a concentration of 1%;

[0037] 2) Zinc chloride with a zinc content of 2.5% by zeolite weight, and sodium bisulfite equimolar with zinc chloride, are slowly added in the suspension slurry of step 1) under stirring, and the N 2 React at 90°C for 10 hours;

[0038] 3) the suspension slurry in step 2) is filtered and dehydrated;

[0039] 4) drying and pulverizing the filter cake obtained in step 3) to 500 mesh to obtain a zinc supplement of loaded ultrafine zinc powder.

[0040] The transmission electron microscope observation shows that the average particle size of the zeolite-loaded ultrafine zinc powder is 12nm, and the particle size distribution is between 8nm and 20nm. The content of zinc in the zeolite is 2.5% by weight.

Embodiment 3

[0042] 1) Grinding a commercially available ZSM-5 zeolite molecular sieve to 500 mesh, adding water and stirring evenly to make a suspension slurry with a concentration of 5%;

[0043] 2) Zinc nitrate with a zinc content of 4% by zeolite weight, and potassium borohydride with a molar ratio of 0.5 times zinc nitrate are slowly added to the suspension slurry in step 1) under stirring, and N 2 Reaction at 100°C for 10 hours;

[0044] 3) the suspension slurry in step 2) is filtered and dehydrated;

[0045] 4) drying and pulverizing the filter cake obtained in step 3) to 500 mesh to obtain a zinc supplement of loaded ultrafine zinc powder.

[0046] The transmission electron microscope observation shows that the average particle size of the zeolite-loaded zinc powder is 40nm, and the particle size distribution is between 20nm and 65nm. The content of zinc in the zeolite is 4% by weight.

Abstract

An zinc supplement used for the forage of animals and fowls and human health-care food or medicine is a porous mineral material carried superfine Zn powder. It is prepared through providing mineral material as micro reactor and reducing the Zn salt to obtain superfine Zn powder.

Description

technical field [0001] The invention relates to a zinc supplement for loaded superfine zinc powder, its preparation method and use, in particular to a zinc supplement for superfine zinc powder loaded with porous mineral materials, its preparation method and its use. Background technique [0002] Zinc is an essential trace element for the body. It has been proven that zinc participates in the composition of more than 300 enzymes and functional proteins in animals. It not only participates in the metabolism of DNA, RNA, proteins, sugars, lipids, vitamins and minerals in animals, And it is related to the function and activity of insulin cord, glucagon, prostatic cord, gonadotropin, etc. In addition, zinc is also a component of many functional proteins such as metallothionein, nucleoprotein, receptor, etc., so zinc has a wide range of physiological and biochemical functions. Zinc nutrients can be divided into: 1) Inorganic zinc: including zinc sulfate, zinc oxide, zinc carbonat...
