Description
Technical field
The present invention relates to sterilization field, particularly a kind of quickly fumigant and method.
Background technology
In the large-scale cultivation of poultry, when carrying out batch and hatching, need hatching egg is carried out disinfection and incubate to improve
Rate, reduces number of dying of illness；At present in the sterilization method of hatching egg, most popular formaldehyde-potassium permanganate is smoked
Steaming method, has an advantage in that sterilization rapidly, and effect is preferable, and shortcoming is that formaldehyde toxicity is excessive, to human body and environment
Being respectively formed harm, many enterprises all begin attempt to find new method to carry out fumigation.
Chlorine dioxide, because of its efficient, feature of environmental protection, is gas form because of itself again, is ground by more and more
Study carefully for fumigation, have document report investigation and comparison chlorine dioxide and formaldehyde-potassium permanganate that hatching egg is smoked
Steaming Disinfection Effect, conclusion is to reach identical effect；Because the use of formaldehyde can be more and more restricted, use
It is promising that chlorine dioxide replaces first that hatching egg is carried out fumigation.
The time of hatching egg fumigation, generally at about 30 minutes, is on the one hand the long time to damage hatching egg,
The most long disinfecting time also affects the production efficiency of enterprise.
But, chlorine dioxide is gas, stores as product, transports or directly uses and inconvenient, the most all
It is as product form, to common are compound sodium chlorite, stable type titanium dioxide by generation chlorine dioxide indirectly
Solutions of chlorine etc., discharge chlorine dioxide and reach application target by dissolving or add acid activation during use.And it is existing
Veterinary drug national standard (" veterinary drug national standard " (chemical drugs, middle powder stick) first, in July, 2013
Publish, Chemical Industry Press) in be that sodium chlorite part is made to the regulation of compound sodium chlorite disinfectant
Solid, makes liquid by activator hydrochloric acid.If both directly mixing can not produce bumping even explosion phenomenon, therefore not
Can be directly used in the most stifling.If using compound sodium chlorite quickly to fumigate at present, it is necessary to by specific
Auxiliary equipment (such as generator or heater) can realize.
Summary of the invention
For solving the problems referred to above, it is an object of the invention to provide a kind of quickly fumigant, it can be used for directly
Fumigation, in 30 minutes, the release rate of effective ingredient (chlorine dioxide) i.e. can reach more than 90%.
Another object of the present invention provides a kind of quickly fumigating method.
The object of the present invention is achieved like this: a kind of quickly fumigant, it is characterised in that comprise A, B
Bi-component:
Component A is liquid, contains by mass percentage: sodium chlorite 16～25%, alkali 6～10%, water
Surplus；
B component is solid, contains by mass percentage: solid acid 50～80%.
Described alkali is selected from sodium hydroxide, the one or two kinds of of potassium hydroxide solution.
Described solid acid is selected from sodium bisulfate.
Described inorganic salt is selected from or several in sodium chloride, potassium chloride, sodium sulfate.
Described B component contain solid acid 50～80%, inorganic salt surplus.
Described A, the mass ratio of B component are 1:0.9～1.1.
A kind of the most stifling method, it is characterised in that: by airtight for required disinfection space, take above-mentioned disinfectant,
B component is uniformly laid on container, is subsequently poured into component A, after 30～60 minutes, i.e. complete fumigation.
The quick fumigant product of the present invention, is used conveniently and safely, and release rate is high, it is not necessary to by any auxiliary
Help equipment (such as generator or heater), also without dilution, be directly simply mixed and i.e. can be used for quickly
Fumigation, in 30 minutes, chlorine dioxide just can reach the release rate of more than 90%, and utilization rate is high, warp
Ji is calculated, and is especially suitable for the fumigation of poultry hatching egg.
Detailed description of the invention
The present invention is a kind of quickly fumigant, comprises A, B bi-component:
Component A is liquid, contains by mass percentage: sodium chlorite 16～25%, alkali 6～10%, water
Surplus.In sodium chlorite solution, add alkali, on the one hand can stablize sodium chlorite, additionally can also improve
The effusion rate (improving more than 10%) of chlorine dioxide when the most stifling, its principle is the acid-base reaction short time
Interior Fast exothermic, increases temperature, thus improves the effusion rate of chlorine dioxide, it is preferred that alkali is selected from hydrogen-oxygen
Change sodium, the one or two kinds of of potassium hydroxide solution.
B component is solid, contains by mass percentage: solid acid 50～80%.Preferably, solid acid
Selected from sodium bisulfate.Preferably, B component contain solid acid 50～80%, inorganic salt surplus, to prevent solid
Acid caking or deliquescence.Inorganic salt can be selected from sodium chloride, potassium chloride, sodium sulfate or several.
Preferably, above-mentioned A, the mass ratio of B component are 1:0.9～1.1.
When quickly fumigating, by airtight for required disinfection space, take above-mentioned disinfectant, by B component uniform spreading
In container, it is subsequently poured into component A, after 30～60 minutes, i.e. completes fumigation.
Component A is designed to the solution of sodium chlorite concentrations 16-25% by the present invention, and B component uses solid simultaneously,
Bumping is occurred even to explode when not only can prevent A, B component from mixing, and also for reducing solvent as far as possible
Consumption, because chlorine dioxide has certain dissolubility in water, the consumption reducing solvent can improve chlorine dioxide
Release rate.It is additionally, since gas solubility with temperature in water to raise and reduce, therefore highly basic in component A
Content is higher, employs this middle strong acid of sodium bisulfate in B component, it is therefore intended that quickly neutralizes when mixing and puts
Heat, makes system temperature quickly raise, and improves the release rate of chlorine dioxide.
