Abstract
The present invention relates to a formula and a preparation method of silkworm medicine. A broad-spectrum silkworm disinfectant is prepared from components which has special sterilization function to a silkworm room and a silkworm instrument through chemical reaction. The broad-spectrum silkworm disinfectant is suitable for popularization and application for wide silkworm zones.
Description
The present invention relates to a kind of silkworm medicine composition and preparation method.In silkworm already produces, sterilizing prevent disease is a most important ring in the whole technique link, and silkworm medicine (disinfactant for silkworm) is to put out cause of disease, the prevention flacherie takes place and popular assurance, in recent years, the research of silkworm medicine is round chlorine-containing agent, the aldehyde preparation, carry out aspects such as oxidant, by medicine the single effect of specific pathogen is developed to the direction to the effect of multiple cause of disease wide spectrum, become single composition compound to multiple composition, the direction that is mixed develops and since to the attention of silkworm medicine development work and diseases prevention disinfection thoroughly, Japanese flacherie loss has been controlled in 3%, China is because single and quantitative deficiency and the quality of silkworm medicine on category can not get assurance, caused sterilization not thorough, residual cause of disease is wide, flacherie takes place many, thereby has influenced the output of silk cocoon, flacherie is lost in about 10%, and Sichuan is more than 17%.At present, in the sericulture of China, general its composition instability of the bleaching powder of usefulness, effect is difficult to be guaranteed, and supplies also very nervous; Formalin uses just can reach optimum efficiency in confined space mainly by its steam sterilization, uses inconvenient, and price is higher, be difficult in the silkworm raiser, promoting, therefore, be badly in need of a kind of multiple cause of disease all being had the high efficiency of killing action, broad spectrum activity silkworm medicine easy to use.
The object of the present invention is to provide a kind of stable components, effect is good, and is easy to use, the silkworm medicine of compound multiple-effect.
Another object of the present invention is to provide a kind of method for preparing above-mentioned silkworm medicine, alleviates the dull under-supply contradiction of silkworm medicine kind, reduces silkworm medicine cost.
The object of the invention can reach by following scheme, and said silkworm medicine is by NaOH weight ratio 20.8～22.8%, Na
3PO
4Weight ratio 0.7～2.7%, H
2O weight ratio 64.2～66.2%, Cl
2Weight ratio 10.3～12.3% is formed.
Above selected silkworm medicine component, can make the silkworm medicine by following method.Press prescription percentage with Na
3PO
4Be dissolved in H
2After treating its whole dissolvings among the O, add NaOH again, slowly feed Cl then
2, Bian Tongbian stirs, and reacts 2 minutes-2 minutes 30 seconds, and reaction temperature is no more than 50 ℃.
Selected component is to develop by practice among the present invention program, hypochlorite has stronger oxidation, energy oxidation cause of disease albumen, highly basic has stronger corrosion (dissolving) effect to cause of disease, sodium phosphate has obvious synergistic effect, and three kinds of components are compound and obtain a kind of composite disinfectant that contains multiple disinfection composition.
The solution of the present invention is described further by embodiment, and said each components by weight of silkworm medicine is NaOH-21.8%, Na
3PO
4-1.7%, H
2O-65.2%, Cl
2-11.3%, best in the silkworm drug effect fruit of this ratio preparation.
Get Na in the present embodiment
3PO
41.7kg, under 45 ℃, be dissolved in 65.2kgH
2Among the O, treat that its full 22.7kg content that adds again after molten is that 96% industrial NaOH solid (is amounted to pure Na
3OH is 21.8kg), feed 11.3kgCl at last
2Notice that Bian Tongbian stirs Cl
2Gas is controlled at 45 ℃ with reaction temperature after feeding, and makes its natural reaction 2 minutes and 15 seconds.It is yellowish to shallow dark brown that the silkworm medicine that is generated is, and normal temperature is the smelly liquid of tool chlorine down, and proportion 1.2-1.3, soup are strong basicity (PH＞12), can any ratio mix mutually with water, and growth, physique and the cocoon quality of silkworm had no adverse effects.
Gained silkworm medicine of the present invention is compared with existing silkworm medicine, has the following advantages:
The silkworm medicine of various dose has good Disinfection Effect to common disease such as virosis (matter type pus illness, nuclear polyhedrosis), nosomycosis (white muscardine, aspergillosis) bacterial disease and granulosis, is a kind of broad spectrum activity disinfactant for silkworm.
This silkworm medical instrument has ingredient stability, and characteristics easy to use are used This silkworm medicine is promoted easily than bleaching powder, formalin economy, and the raw material of producing this silkworm medicine is easy to get, and equipment is simple, can reduce the pollution of production environment simultaneously.
Use 0.5% silkworm medicine, 1% lime white sterilization silkworm room and rearing instrument, to silkworm grow and the amount of cocoon production has no adverse effects, test shows, this method single box of sterilizing produces cocoon 29.7kg, improves 7.4% than contrast kind of the per unit area yield of breeding silkworms with 1-2% bleaching fluid or lime white sterilization.
In sum, the product of this invention is successful.
