Abstract
To solve the problem that the sterilization range of the existing disinfectant is not applicable to article disinfection, the invention provides an acid washing sterilization disinfectant and a use method thereof, and belong to the technical field of composite sterilization disinfectants, wherein the sterilization disinfectant comprises 0.2-1mol.L<-1> hydrochloric acid, potassium permanganate and sodium thiosulfate (the mole ratio of HCl in the hydrochloric acid to the potassium permanganate and the sodium thiosulfate is 1:(0.0106-0.137):(0.027-0.312), and the sterilization disinfectant can be used for killing bacterium, virus, rickettsia, chlamydia, mycoplasma, spirochete, actinomycetes and as well as fungus, mold, parasite and the like. The acid washing sterilization disinfectant integrates the functions of disinfection, sterilization and whitening, furthermore dirty in seams can be washed, enhanced composite sterilization effects are achieved, the sterilization range is increased, and pathogen can be sterilized, which is impossible for a single sanitizer; and the sterilization disinfectant can be used for washing public urinals in hospitals after being used, so that the sterilization disinfectant can be both used for sterilizing and washing urine dirty and the like.
Description
Technical field
The present invention relates to a kind of acid washing and sterilizing disinfectant and using method thereof, belong to the technical field of composite sterilization disinfectant.
Background technology
Remove easy breed bacteria and mould because the inner residue of hospital's hand brush, all kinds of hairbrush slit is difficult, residue cleans totally not only not attractive in appearance, and disinfection thoroughly not have hidden danger be a present difficult problem.Have again blood sampling with in the middle of the rack for test tube if utensils such as the washbowl that having residual bloodstain hairbrush to be difficult to brushes, the lazaretto ward patient uses, Sputum cup (broad-mouthed receptacle for holding liquid), chamber pot, toilet have the dirt of urine and smell big, do not sterilize and easily propagate infectious diseases such as skin disease, venereal disease, hepatitis, so need especially to remove the slit dirt, again can wide spectrum kill bacteria (Gram-positive and Gram-negative bacteria), pathogene, parasitic disinfectant such as fungi, virus, gonococcus, mould, trichomonad, microspironema pallidum, this invention disinfectant all can satisfy every requirement.Virus, bacterium, fungi, parasite etc. all are the arch-criminals who causes infectious disease, have public object each hospital, hotel, hotel, receive in one's power that family all will use in a large number, according to statistics because floating population's increase, infectious disease incidences such as venereal disease, skin disease, hepatitis have the tendency that increases at present, so resolve the sterilization problems of public place, the propagation of control infectious disease is the task of top priority of society.
Summary of the invention
But; The sterilization scope of existing each disinfectant has the limitation that is not suitable for sterilizing objects.In order to address this problem, but the invention provides a kind of can kill bacteria, the acid washing and sterilizing disinfectant of virus, rickettsia, Chlamydia, mycoplasma, conveyor screw, actinomycetes and fungi, mould, parasite etc.Have wide spectrum, sterilized (but various microorganisms such as kill vegetative forms of bacteria, fungi, virus and bacterial spore), little to environmental influence, economic environmental protection.
The present invention also provide should acidity washing and sterilizing disinfectant using method.
Technical scheme of the present invention:
A kind of acid washing and sterilizing disinfectant is by concentration 0.2-1 molL
-1Hydrochloric acid, potassium permanganate and sodium thiosulfate are formed; The mol ratio of HCl, potassium permanganate, sodium thiosulfate is 1:0.0106-0.137:0.027-0.312 in the hydrochloric acid.
Above-mentioned acid washing and sterilizing disinfectant, the concentration of hydrochloric acid is preferably 0.6024mol/L.
Above-mentioned acid washing and sterilizing disinfectant, HCl, potassium permanganate, the preferred mol ratio of sodium thiosulfate are 1:0.0315:0.064 in the hydrochloric acid.
A kind of using method of above-mentioned acid washing and sterilizing disinfectant comprises the steps:
At first, the article that needs are handled place hydrochloric acid, soak 10-30min;
Then, add potassium permanganate and it is dissolved fully after leave standstill 5-45min;
At last, add again sodium thiosulfate and it is dissolved fully after leave standstill 15-50min.
Described article are non-metal article, alloy and the metal (as copper, platinum, gold) that comes the hydrogen back in the periodic table of elements.
The using method of above-mentioned acid washing and sterilizing disinfectant,
The soak time of step (1) is preferably 15-20min, more preferably 15min;
The time of repose of step (2) is preferably 15-20min, is more preferably 20min;
The time of repose of step (3) is preferably 25-30min, is more preferably 30min.
The using method of above-mentioned acid washing and sterilizing disinfectant, preferred, step (1) (2) (3) is all carried out under closed environment; More preferably adopt and have the plastic box of lid as container.
The using method of above-mentioned acid washing and sterilizing disinfectant, the preferred method of shaking with oscillator that adopts makes potassium permanganate and sodium thiosulfate dissolving.
The using method of above-mentioned acid washing and sterilizing disinfectant, preferred for the more article of grease, in step (1) before, earlier with 0.1% acid degreasing agent (BG-CLEANER) article-cleaning.
The using method of above-mentioned acid washing and sterilizing disinfectant, preferred, filter after step (3) finished treatment fluid; And treatment fluid be used for cleaned incrustation scale, urine dirt and tea stain; Preferred, soak incrustation scale, urine dirt and tea stain 5-15min with treatment fluid.
On the sterilizing objects during microbial contamination especially severe, during article that sterilization is polluted by blood, fester etc., need proper extension action time.
Acid washing and sterilizing disinfectant of the present invention, watery hydrochloric acid can kill part bacterium and virus in the process of soaking article; And potassium permanganate chance organic matter is namely emitted the effect that nascent oxygen has kill bacteria, discharges chlorine under the hydrochloric acid effect, and further bacterial propagule, virus, fungi, tubercle bacillus and pathogene such as bacterial spore, conveyor screw are killed in sterilization, and sterilization is bleached; And then generate the sulphur effect of a step disinfection again with the sodium thiosulfate effect, also produce sulphur dioxide and the sulphur (hairbrush easily produces mould and fungi, and sulphur dioxide and sulphur are to its special efficacy) that bleaching and antisepsis are arranged simultaneously.The present invention makes each component both can bring into play self sterilization, disinfection efficacy when interacting by limiting wherein consumption and the concentration of each component; The material that possesses sterilization, sterilization, bleaching effect of release new can interact again.
Acid washing and sterilizing disinfectant of the present invention is usually used in the sterilization to the utensil in article such as all kinds of hairbrush of hospital, plastic test tube frame, enamel chamber pot, enamel, ceramic toilet and infectious disease ward.Also but inner wrapping is used for the article that there are the epidemic victim in family disinfection toothbrush and family, with after clean the lavatory urinal again.The amount of finished product hydrochloric acid, potassium permanganate and sodium thiosulfate of can designing a package according to user's needs satisfies preparation 0.5L, 1L, 5L, 10L, the acid washing and sterilizing disinfectant of 50L supply the market.
Beneficial effect of the present invention:
(1) integrates the effect of sterilization, sterilization, bleaching; Can also clean the dirt in slit;
(2) possessing several bactericidal effects that repeat to close, the sterilization scope is increased, can kill pathogene, is that independent disinfectant is not available;
(3) can be used for cleaning the public urinal of hospital after the use, can sterilize, can clean up urine dirt etc. again; Can be used as the efficient clear lavatory agent of sterilization.
