Embodiment approach

[0023] Due to the very high specific surface energy of nanoparticles, if they are not treated during the preparation process, the obtained nanoparticles often lose many of the properties of nanoparticles due to agglomeration, which limits their research and application. In order to overcome the agglomeration of nanoparticles, stabilizers, such as polymers and surfactants, are generally added to coat the surface of nanoparticles during the reaction process to reduce their surface energy. In recent years, using the confinement effect of nano-reactors, such as the nano-water center in the center of capsules and microemulsion droplets as the reaction medium, uniformly dispersed nanoparticles with smaller particle sizes can be obtained. Similarly, some porous mineral materials with nanopores in their structure also have a confinement effect and can be used as a carrier and medium for manufacturing nanostructure assembly materials. The present invention utilizes the nanopore structu...

Abstract

The invention discloses feed addictive carrying super fine chromium and the preparing and usage method. The super fine chromium is carried by porous mineral material, the average grain size of chromium is smaller than100 nanometer, and the chromium content in the porous mineral material is 0.05-0.5% by weight percent. The invention employs porous mineral material as microreactor, and adds reducer to reduce chromate salt to chromium. The bore diameter of porous material is uniform, and so the distribution of grain size of chromium is narrow. The chromium powder is characterized by low toxicity and high effective, and can be used for cow, sheep, poultry and aquatic creature, and the powder is easy to mix with feed stuff.

Description

technical field [0001] The invention relates to a chromium-supplementing feed additive loaded with superfine chromium and a preparation and use method thereof, in particular to a chromium-supplementing feed additive loaded with ultrafine chromium powder by a porous mineral material and a preparation and use method thereof. Background technique [0002] Chromium is a transition metal element first discovered in 1797 by a French chemist (Louis Vanquelin). In 1957, Mertz and Schwarz first proposed the glucose tolerance factor (glucose tolerance factor, GTF) hypothesis, and in 1959 it was confirmed that chromium is an essential element for the growth and maintenance of GTF in rats. The biological function of chromium: [0003] (1) Improving the immunity of animals: Adding chromium to the feed can stimulate lymphocytes to produce immune stress products to improve the immunity of animals. [0004] (2) Improve animal carcass quality: A large number of studies have shown that chro...
