Problems solved by technology

Although copper sulfate has the advantage of low price, it also has many substantial defects: 1. It has high water solubility and is very easy to absorb water, so it is easy to be damp and agglomerated, and it is easy to harden and corrode processing and production equipment
2. It has a strong oxidation effect and is easy to be reduced, which can destroy the vitamins in the feed and lead to fatty acid spoilage, thus destroying the nutritional content of the feed to a certain extent
3. The absorption and utilization rate of copper sulfate is low, and it has an antagonistic effect on the absorption of other trace elements, such as iron and zinc, which greatly reduces the normal absorption of trace elements in feed, and affects the normal metabolism and biological function of animals. Utilization
4. When used in large quantities, the soluble copper content in animal feces is high, and when discharged in large quantities, it will bring great pollution to the environment, especially water bodies
However, the spectroscopic study of basic copper chloride shows that in the crystal structure of basic copper chloride, the hydrogen bond strength in the basic copper chloride and paratacamite is greater than that of botallackite, so the botallackite The physical and chemical properties of copper ore are not as stable as that of chloride and paratacamite, and the moisture resistance and agglomeration and the storage period of the product are not as good as the two

Abstract

The invention provides a preparation method of an alkaline copper chloride crystal. The alkaline copper chloride crystal adopts paratacamite; a preparation method of the paratacamite comprises steps as follows: botallackite and water are added to a reactor to form a reaction system, the reaction system is heated, the pH (potential of hydrogen) and the reaction time of the reaction system are controlled, and precipitates of paratacamite are generated. The paratacamite prepared with the method is used as a feed nutrition additive, the stability of the paratacamite crystal is excellent, the problem of caking of alkaline copper chloride products can be solved, and great convenience is brought to storage and use of the products.

Description

Technical field [0001] The invention relates to the production and utilization technology of basic copper chloride, in particular to a preparation method and application of a basic copper chloride crystal-parachlorocopperite, and belongs to the technical field of basic copper chloride preparation. Background technique [0002] In the animal breeding industry, copper is a trace element necessary for animal growth. It plays an important role in maintaining the normal physiological metabolism of the animal body and improving immunity. It can participate in the synthesis of heme and the maturation of red blood cells. Osteogenesis, pigmentation and keratinization of hair and fur. A large amount of feeding data proves that the addition of copper can increase the growth rate of animals, the daily food intake and promote the refinement and high quality of feed. [0003] As the most important and first copper additive developed, copper sulfate has long been the most common source of copper...
