Abstract
本发明公开了强酸弱碱盐或强碱弱酸盐在作为B型碱式氯化铜防结块剂中的应用。本发明发现将强酸弱碱盐或强碱弱酸盐添加到B型碱式氯化铜中，在充分搅拌的条件下，B型碱式氯化铜与强酸弱碱盐或强碱弱酸盐发生反应，B型碱式氯化铜的晶态结构趋于稳定，从而不再结块，克服了B型碱式氯化铜结块影响使用的缺陷。将强酸弱碱盐或强碱弱酸盐添加到B型碱式氯化铜中，使得B型碱式氯化铜的稳定性更好，长期贮存不结块。添加了强酸弱碱盐或强碱弱酸盐的B型碱式氯化铜可用作动物饲料添加剂。The invention discloses the application of a strong acid and weak base salt or a strong base and weak salt as a B-type basic copper chloride anti-caking agent. The present invention finds that strong acid and weak base salt or strong base and weak salt are added to B-type basic copper chloride, and under the condition of sufficient stirring, B-type basic copper chloride and strong acid and weak base salt or strong base and weak salt After the reaction occurs, the crystalline structure of the B-type basic copper chloride tends to be stable, so that it no longer agglomerates, and overcomes the defect that the B-type basic copper chloride agglomerates affects the use. Adding strong acid and weak base salt or strong base and weak salt to B-type basic copper chloride makes the B-type basic copper chloride more stable and does not agglomerate in long-term storage. The B-type basic copper chloride added with strong acid and weak base salt or strong base and weak salt can be used as 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.The reproduction of copper and animal also has 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 the method preparation is water insoluble but soluble in weakly acid soln because having; good fluidity; be easy to feed formulation; VITAMIN and the lipid in the catalyzed oxidation feed hardly; the bioavailability of copper is high; the growth promotion addition is little; be conducive to the advantages such as food safety and environment protection; and the traditional copper sulfate of replacing is used for fodder additives, and herding circle at home and abroad is promoted 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 larger, perhaps product fully dry, still contain in the situation of a small amount of moisture content, the phenomenon that caking and color bleach occurs easily, affected its Uniform Dispersion 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, the method utilizes mineral acid or organic acid to the chemical catalysis weathering of 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 respectively a kind of basic copper chloride that covers selenium and iron content, utilization contains the chemicals of selenium and iron content to the surface modification effect of crystalline state basic copper chloride, so that its crystal is more stable, be not easy caking.
Summary of the invention
The present invention is intended to solve the easily problem of caking of basic copper chloride, 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 for preventing 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 impact 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, so 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.
