Abstract
The invention discloses application of a strong acid weak base salt or a strong base weak acid salt in serving as an anti-caking agent of type B basic copper chloride. The invention discovers that: the type B basic copper chloride reacts with the strong acid weak base salt or the strong base weak acid salt under a condition of sufficient stirring when the strong acid weak base salt or the strong base weak acid salt is added into the type B basic copper chloride, the crystalline structure of the type B basic copper chloride tends to be stable and cannot be agglomerated again, and the defect that the agglomeration of the type B basic copper chloride influences the use is overcome. The strong acid weak base salt or the strong base weak acid salt is added into the type B basic copper chloride to ensure that the type B basic copper chloride has better stability, can be stored for a long time without agglomeration. The type B basic copper chloride added with the strong acid weak base salt or the strong base weak acid salt can be used as an animal feed additive.
Description
Technical field
The present invention relates to the preventing blocking technology of Type B basic copper chloride.
Background technology
Copper can participate in the hemopoietic function of human body, plays an important role in the synthetic and erythrocytic ripening process of protoheme.Copper mainly is pigmentation and the keratinization process that participates in osteogenetic process, hair and the fur of animal body as the essential composition of plurality of enzymes in animal body.Copper and animal reproduction also have extremely close relation, and it is the essential micronutrient element that adds of animal-feed, and it is as Animal nutrition supplement and growth stimulant, and herding circle at home and abroad is used widely.Chinese patent 200610060144.1 discloses the preparation method of a kind of Type B (Botallachite) crystal basic copper chloride; the Type B crystal basic copper chloride of this method preparation is because of having water insoluble but easily be dissolved in weakly acid soln; good fluidity; being easy to feed cooperates; VITAMIN and lipid in the catalyzed oxidation feed hardly; the bioavailability height of copper; the promotes growth addition is little; help advantages such as food safety and environment protection; and progressively replacing traditional copper sulfate to be used for fodder additives, herding circle at home and abroad obtains promoting as animal micronutrient element supplement.
In production and practical application, find, the Type B crystal basic copper chloride is in storage process, particularly higher at temperature, humidity is bigger, perhaps product not thorough drying, still contain under the situation of small amount of moisture, occur the phenomenon that caking and color bleach easily, influenced its homodisperse in the feed process for preparation.Trace it to its cause, basic copper chloride because of contain ammonium chloride, storage temperature height, high humidity, pressurized and long time stored be the externalities that causes its caking, the unstable of the crystalline structure of himself is the internal factor of its caking.
Chinese patent 200810218161.2 discloses a kind of preparation method of acid catalysis air slaking B type copper chloride hydroxide, this method is utilized mineral acid or the organic acid chemical catalysis weathering to the crystalline state basic copper chloride, the crystal grain cracking and puffing, cracked is 0.1～50 micron particle.By rapid ageing, do not had activity and cohesive force by the cracked particle of acid catalysis air slaking, therefore more stable, caking no longer.And patent 200810216000.X and patent 200810217571.5 have prepared a kind of selenium and ferruginous basic copper chloride of covering respectively, utilization contains the surface modification effect to the crystalline state basic copper chloride of selenium and ferruginous chemicals, make that its crystal is more stable, be not easy caking.
Summary of the invention
The present invention is intended to solve the basic copper chloride problem of caking easily, and a kind of anti-hard caking agent strong acid weak base salt or strong base-weak acid salt of Type B basic copper chloride are provided.
The contriver finds that through lot of experiments strong acid weak base salt or strong base-weak acid salt can be used to prevent Type B basic copper chloride caking, can be as the anti-hard caking agent of Type B basic copper chloride.
Utilize strong acid weak base salt or strong base-weak acid salt to prevent that the method for Type B basic copper chloride caking from comprising the steps:
A, add the Type B crystal basic copper chloride in the mixing vessel, start mixing vessel, in the process of mixing vessel running, add strong acid weak base salt or strong base-weak acid salt.
Strong acid weak base salt or strong base weak acid salt pair Type B crystal basic copper chloride that b, utilization add carry out surface modification, obtain complete non-caking Type B basic copper chloride.
In the step a of aforesaid method, described strong acid weak base salt or strong base-weak acid salt wiring solution-forming add, and the add-on of strong acid weak base salt or strong base-weak acid salt is the 0.5%-1% of Type B crystal basic copper chloride weight percent.
Described strong acid weak base salt is preferably any in copper sulfate, cupric chloride, cupric nitrate, ammonium chloride, ammonium sulfate, ammonium nitrate, iron(ic) chloride, zinc chloride, ferric sulfate, iron nitrate, zinc sulfate, the zinc nitrate.Described strong base-weak acid salt is preferably any in sodium-acetate, calcium acetate, Potassium ethanoate, yellow soda ash, salt of wormwood, potassiumphosphate, the sodium phosphate.
Compared with prior art, the present invention has following beneficial effect:
The present invention finds strong acid weak base salt or strong base-weak acid salt are added in the Type B basic copper chloride, under well-beaten condition, Type B basic copper chloride and strong acid weak base salt or strong base-weak acid salt react, the crystalline structure of Type B basic copper chloride tends towards stability, thereby no longer caking has overcome the defective that the influence of Type B basic copper chloride caking is used.
Strong acid weak base salt or strong base-weak acid salt are added in the Type B basic copper chloride, make that the stability of Type B basic copper chloride is better, long storage is not lumpd.The Type B basic copper chloride that has added strong acid weak base salt or strong base-weak acid salt can be used as animal feedstuff additive.
