Description
Technical field
The present invention relates to field of feed additive technology, particularly relate to a kind of coating calcium chloride and preparation method thereof.
Background technology
Calcium chloride is inorganic compound, is a kind of salt be made up of chlorine element and calcium constituent, is typical ionic halide.Calcium chloride molecular formula is CaCl
2, relative molecular mass is 110.98, and proterties is white, hard fragment or particle, micro-hardship, odorless.The hygroscopicity of calcium chloride is extremely strong, and to be exposed in air very easily deliquescence, soluble in water, release a large amount of heat, its aqueous solution is alkalescence simultaneously.
Calcium chloride is often applied in dairy cow diet as anion salt additive, there is anion needed for supplementary milk cow, reduce dairy cow diet DCAD (daily ration ionic equilibrium) value, improve the functions such as milk cow body fluid acid-base balance, effectively can increase the concentration of blood Free Calcium, reduce the generation of low blood calcium, reduce the incidence of disease of milk fever, retention of afterbirth and left displaced abomasums, add the output of milk, improve reproductive performance, improve conception rate.
The common calcium chloride very easily moisture absorption, strong to the mechanical erosion of feed, easily cause feed to lump and destroy other nutritional labelings.In addition, if calcium chloride Direct-fed is easily caused milk cow food refusal, have intense stimulus effect to body tissue, can impact ruminal pH value, during rumen bypass, loss is larger.Therefore, common calcium chloride is not suitable for Direct-fed.
The technological means of carrying out reasonable employment to calcium chloride in prior art mainly contains intravenous injection and calcium chloride gel is fed, but, intravenous injection and the requirement of calcium chloride gel feeding method to operating technology higher, efficiency is lower, and stress be larger to milk cow.In addition to the above methods, film-coating technique is also had, namely by selecting dissimilar coated fertilizer to carry out coating to calcium chloride, prevent the calcium chloride moisture absorption from luming as much as possible, reduce calcium chloride to the stimulation of body, make calcium chloride stable when rumen bypass, reach onset after small intestine.
At present, in feed additive field, types of functionality material obtains stable micro-capsule by the form of coating, then mix with feed or the research of Direct-fed more.Such as: application publication number is that the Patent Application Publication of CN103652366A discloses and a kind of stablizes micro-capsule coating Mercaptamine and preparation method thereof, this stable micro-capsule coating Mercaptamine is made primarily of the raw material that quality proportioning is following: Mercaptamine 20 ~ 55 parts, cornstarch 15 ~ 35 parts, sodium carboxymethylcellulose 0.1 ~ 10 part, sodium alginate 1 ~ 10 part, ethyl cellulose 0.1 ~ 10 part, beta-schardinger dextrin-10 ~ 15 parts, Brazil wax 10 ~ 50 parts.The preparation method of this coating is: by mass concentration be 1 ~ 10% sodium carboxymethyl cellulose solution mix with cornstarch, sodium alginate, ethyl cellulose and beta-schardinger dextrin-after, again the Mercaptamine after heating and melting is joined wherein, carry out fluidized bed granulation, carry out dressing at the Brazil wax adding liquid state, obtain finally stable micro-capsule coating Mercaptamine.
But the film-coating technique being directed to calcium chloride is at present also immature, solve the poor effect of moisture absorption problem, be difficult to promote.Therefore, be necessary to probe into a kind of film-coating technique can avoiding the calcium chloride moisture absorption, for feed additive field provides a kind of stable coating calcium chloride.
